Zack Snipes reports, “Finally we have a break from the rain! I lost count of how many inches of rain we had. In fields with clean ditches and water furrows, water drained off pretty quickly, however, some fields suffered from all the rain. If your fields are wet, try to stay out of them until they dry. One of the worst things that can happen is when fields are entered when wet and soggy, causing compaction issues in the soil. I am seeing lots and lots of disease in strawberry and blueberry. The cold weather a few weeks ago killed many developing fruit and blossoms leaving them vulnerable to fungal infection. With over a week of consistent rain/cloudy weather and mild temperatures, the fungal pathogens have exploded. If you can get into your fruit fields then both protectant and systemic fungicides should be applied.

Justin Ballew reports, “We had lots of rain last week, but a very nice weekend and I saw the first bit of pollen on my windshield Saturday afternoon. Despite the rain, spider mites are starting to build up in strawberries in several places, requiring treatment. This is probably a result of having the row covers on for so long. Conditions are still perfect for disease development and we are seeing lots of Botrytis as well as some anthracnose fruit rot. More rain is coming this week, so be timely with fungicide applications and be sure to sanitize dead leaves, flowers, and fruit from the plants. These become sources of inoculum as disease develops, so get that material out of the field.

Pee Dee

Tony Melton reports, “Fields are rapidly drying – hopefully, it doesn’t rain until later this week so we can finally get some greens planted. We have got some acres planted but there are thousands left to be planted. Peaches are still up in the air. Some varieties are totally lost but others are fine. Growers are running wind machines and burning hay bales most nights to protect blooms from the cold. Covering and watering to protect strawberries and some growers have been picking for weeks, though others want to wait until they have enough fruit to open. With all the rain, Botrytis is tough on strawberries. Some growers are spraying twice a week, while others are letting it go and will pick-off bad fruit with the good fruit and sell what they can.

Upstate

Kerrie Roach reports, “Last week was the annual ‘Upstate Fruit Grower Meeting’ in Oconee County. Extension Agent, Kerrie Roach, along with Extension specialists from Clemson and NC State presented on topics to more than 30 attendees. Topics covered included apple diseases, PGRs, peach disease management, insect & disease ID, fungicide resistance, blackberry PGR research, the MyIPM app. along with much more. Lots of great networking and conversations were had over lunch and continued after the meeting. The Upstate is looking forward to a great growing season!”

Zack Snipes reports, “The horticulture team got the opportunity to tour some really nice greenhouse/transplant providers last week. One point I’d like to bring up is transplant quality. Yes, quality transplants cost more upfront but healthy, quick-growing plants will help you recoup your investment. I see lots and lots of subpar transplants going into fields that come from transplant providers with disease and insect issues from the start. The plants will require more attention and cost more to fertilize and spray than healthy plants from the start. We also got to see some grafted tomato and melon plants. If you have been having trouble with a particular disease, cultivar, or area within your farm then grafted transplants may be an option for you. I have seen several farms in the past few years switch to using grafted plants and they are loving the results. Again they cost more but they are less likely to die with a full fruit load in late May.”

Midlands

Justin Ballew reports, “We had a little break in the rain over the weekend. Hopefully, strawberry growers have taken advantage of that to sanitize the fields and get a fungicide application out. Conditions have been perfect for Botrytis development (lots of moisture and temps in the 60’s) and we are seeing a ton of it. The MyIPM app is a great resource for determining which fungicides to include in your rotation. There are a few fruit out there that are ripening up, but they’re ugly and don’t taste great yet. This will improve with time as long as pollination is good and we get some sunny days. Keep in mind it’s still very early in the season. Start taking tissue samples now to make sure we get the fertigation right.”

Botrytis growing on decaying tissue is plentiful right now. It’s going to be a rough strawberry season if the rain doesn’t slow down. Photo from Justin Ballew

Sarah Scott reports, “Recent rains have caused a lot of erosion issues in orchards, especially those with trees planted on berms. With more heavy rain in this week’s forecast, farmers should focus on problem areas and consider erosion control methods such as coconut coir logs to help slow the movement of water through the orchard. Peach trees are progressing quickly but it is still too early to make predictions about this year’s crop.”

Pee Dee

Tony Melton reports, “Farmers are hurrying to get greens/cabbage/collards planted before the rain this week. Also, getting sweet potato beds in for transplant production. Growers are fumigating fields for tomatoes, peppers, and other summer vegetables.”

Upstate

Kerrie Roach reports, “Last week several S.C. agents toured two different grafting/vegetable transplant production operations in WNC. Grafting can translate some great resistance/tolerance traits to otherwise susceptible varieties of tomatoes we commonly plant in small scale production. Check with your agent to see if grafted tomato plants might benefit your operation. Meanwhile, in the upstate, it didn’t rain for a few days and growers have finally been able to get into the field to prep and plant some early crops. Temperatures have been typical for this time of the year. Hang tight because more rain is forecasted for this week!

Zack Snipes reports, “As probably guessed the topic of the day is the 2 nights of sub 32F temperatures. Most folks were able to cover their strawberries and hopefully, the row covers did their jobs. I know in some places temperatures lower than 25F were seen. The blueberry crop took the biggest blow. Many of our rabbiteye types were ahead of schedule with the warm weather and were almost in full bloom or close to it when the cold nights came in. I have seen several pictures from several farms that have a good bit of damage. It is important to get fungicides out sometime this week as we have the perfect storm for a disease outbreak (warmer temperatures, wet weather, dead plant tissue, disease inoculum). Recently planted brassicas are showing some damage but should grow out of it. Only time will tell the extent of the cold damage.

Midlands

Justin Ballew reports, “We had plenty of rain last week and two cold nights this weekend. It got to 28 Saturday morning and 29 Sunday morning at my house. Strawberries were all covered, so they were protected, but now we’re getting to where we need to get the row covers off to make a fungicide application. The rain and the threat of near-freezing temperatures this week is holding us back from getting that done. Bees won’t able to get to the flowers for pollination either until we get the row covers off. As soon as we’re able, we need to remove dead flowers, leaves, and fruit from the plants also.

Strawberries split open to show cold damage. The strawberry on the bottom is healthy and the two on top have varying degrees of discoloration and necrosis. If not removed from the field, these two damaged berries will become a source of botrytis inoculum. Photo from Justin Ballew.

Sarah Scott reports, “Wet weather is still prevalent and temperatures have dipped below freezing a couple of nights this past week. Warm weather earlier in the month began to push peach trees into a bit of an early bloom so we are watching for cold injury now. It is still too early to tell if the weather will affect the crop.

Pee Dee

Tony Melton reports, “Rain won’t stop for us to get greens/cabbage/collards planted. Transplants are having to be held back as much as possible so they won’t get too leggy. Some growers got their sweet potato beds planted in real sandy fields. Most strawberry growers have started covering to save fruit. Remember that covering encourages spider mites and fruit rots.”

Upstate

Kerrie Roach reports, “After a couple weeks with cooler temperatures, chill hours for the Upstate fruits crops (apples & peaches) are looking good. The dry weekend was too good to be true as we are getting more rain today. The forecast calls for dry weather the rest of this week. Hopefully, we can start getting into fields for prep work and early plantings for market growers.

Statewide

Dr. Matt Cutulle reports, “Love is in the air, and your crabgrass (Digitaria spp.) PRE herbicides should be on the ground if you are in the Low Country. When soil temperatures reach 55 F for 2 to 3 days, which will usually occur before March 1^st in the Low Country, March 15^th in the Midlands and March 30^th for the upstate crabgrass germination is possible and can continue throughout the spring and summer. No matter how well crabgrass has been controlled in previous years, there is still a tremendous seed bank in the soil and open spots in crop canopy will allow this fast-growing summer annual to invade. Crabgrass’ rapid emergence and extremely fast growth rate make it a problematic weed in early spring to summer. One study by NC State showed that for every week large crabgrass emergence was delayed an increase in 373 watermelon fruit was observed. This relatively small grassy weed can cause a big problem in early season cucurbit crop plantings.”

Coastal

Zack Snipes reports, “A wet week is coming to the Lowcountry. Most farms are discing up land and pressing beds in preparation for the season. I saw some potatoes going in last week on a farm or two. If you have strawberries and have started spraying, then keep spraying. Protectant fungicides applied before a weather event are the best measure at preventing disease. The weather coming is perfect for gray mold and Anthracnose to develop. If you have a smartphone download the MYIPM app (make sure to use WiFi) to key you in on diseases and preventative measures for small fruits.

Midlands

Justin Ballew reports, “More rain on the horizon. Lots of collards are bolting and fall brassicas, in general, are wrapping up. Some spring brassicas have already been planted. Black rot is showing up in some fields following the storms and warm weather, so if, you’re done with a field, get rid of it! It never got cold enough Friday to kill strawberry blooms, but lots of growers had their row covers on just in case. Growers are protecting blooms from now on. This will have us picking around mid-March. Make sure to sanitize the fields as soon as it stops raining and it’s safe to pull off the row covers and start your fungicide programs and fertigation now.

Pee Dee

Bruce McClean reports, “We have been on a bit of a roller coaster for the last couple of weeks… warm temps separated by brief periods of cool, windy conditions. The cool weather has not been that severe or persistent, and the warmer weather has been much more dominant. This has caused crops like blueberries and strawberries to really start to push. Heavy flowering in both crops is very evident now. With strawberries, we’re not too worried about losing early blooms… the plant will make more. But with blueberries, persistent early warm temps can ruin the upcoming season’s crop quickly. Some growers have asked about frost protecting this early. The challenge is “do you have enough water to protect until all risk of frost is gone”… likely not. The only thing worse than losing a crop because you didn’t frost protect is frost protecting all winter only to run out of water on the last night of freezing temps. Try to assess how much water supply you have and try to make decisions based on that. If you need help, please reach out to Clemson Extension for assistance.

Some chores to be doing now – finish up pruning your vineyards and orchards over the next week, or so. Look closely for dead wood in your vineyard, especially on the cordons. Now is the best time to identify it and remove it. Also, if you are planning to do some hardwood propagation on blueberries, now is the time to select one-year-old canes for cuttings. Be sure to keep them bagged (with moist peat moss or pine bark) and refrigerated until you are ready to sprig in the spring.

Tony Melton reports, “Farmers wish the rain would stop so they can get greens planted. One way to keep plants from growing too tall in the greenhouse is blowing with a leaf blower every day it will harden them off and cause them to be shorter. Time to bed sweet potatoes for slips if not to wet. If you’ve started to save/protect strawberries, blueberries, peaches, etc. (some already in full bloom) get ready for Friday night.

Spring fruit and vegetable meetings are being announced daily, so keep an eye on the “Upcoming Events” tab over the next several weeks.

Coastal Region

Dr. Matt Cutulle reports, “I have been seeing a lot of Henbit in the coastal area this year (A big chunk of it in Dr. Brian Ward’s research fields). Don’t be deceived by the pretty flowers. We don’t really have any options for selectively controlling the weed POST in most vegetable crops. Mowing before viable seed head formation is a good way to reduce the weed seed bank deposit of this problematic winter annual. More description of the weed can be found at (https://www.clemson.edu/cafls/research/weeds/weed-id-bio/broadleaf-weeds-parent/broadleaf-pages/henbit.html)”

Dr. Tony Keinath reports,”White mold (Sclerotinia sclerotiorum) is active in the Charleston area. The two nights of freezing temperatures December 18-19 likely stimulated sclerotia to germinate and produce ascospores. Warm, overcast weather with mist and light rain is ideal for spread and germination of the airborne ascospores. Weather conditions likely will remain favorable for white mold over the next 3 months. Growers will need to rotate conventional white mold fungicides due to limits on the number of applications that can be made per crop.

For organic crops, Sonata at 8 pints per acre may offer some protection. See pages 185 and 222 in the 2020 Vegetable Crop Handbook for Southeastern United States.”

Zack Snipes reports, “Warm and muggy is the only way to describe the past week. I was out in a blueberry patch and noticed some low chill hour varieties already blooming. We have gotten very few chill hours to date in Charleston. Chill hours are the number of hours below 45F and are required for proper fruiting of perennial fruits. For a normal year in Charleston we should get anywhere from 400-600 chill hours. I have also seen strawberries pushing out some blooms. Growers should not worry as that is normal for this time of year. I think it is still too early to starting pushing strawberries for fruiting. Remember that it takes 35 or so days to go from bloom to picking a strawberry. It we let our plants grow and develop more crowns right now (rather than fruit), then we will have greater production this spring.”

Midlands

Justin Ballew reports, “It was unseasonably warm this past week and we had a couple significant rain events over the weekend. I’ve seen a few daffodils and forsynthia blooming already. Strawberries are growing a little faster right now and that’s good new for fields that are a little behind. The weather conditions we have right now are very conducive to Phytophthora development, so now would be a good time for a Ridomil application through the drip, especially in fields with a history of Phytophthora. Winter weeds are really exploding now. Make sure to pull any weeds coming up in the plant holes so they aren’t competing with the strawberries. We’re still harvesting brassicas and they look good other than a little Sclerotinia here and there.”

Sarah Scott reports, “Wet and overly warm temperatures have set in along the Ridge over the past week. 2.5 inches of rain have fallen but with soil already wet it is making for difficult working conditions. Fields are still being prepped for peach tree planting and pruning should begin this week. With temperatures reaching into the 70s there is a concern that higher chill varieties of peaches may not get adequate chilling requirements to produce optimum yields but we will have to wait and see what the weather continues to do. Cabbage, collards, and kale are still being harvested along with a few other late winter crops. Strawberries are putting on a lot of growth with the warm temperatures. Some spider mites in the field but very minimal observations.”

Strawberries are growing fast in this warm weather. Photo from Sarah Scott.

Lalo Toledo reports, “Spider mite populations are begging to increase in our area. Most brassica producers are selling out. Remember to disk in remaining plant material as soon as possible, this reduces the chance of disease in your following crop year. Sclerotinia white mold has been very prevalent in our area. Remember to rotate for a minimum of three years if disease emerges. Weather has not allowed for spring bedding to begin.”

Pee Dee Region

Tony Melton reports, “Last week, folks hurried before rain to get land bedded for greens to be planted the first of February. This will allow weeds to emerge so they can be killed before planting in stale-bed-culture. Strawberries are loving this warm weather.”

Upstate

Kerrie Roach reports, “We have some growers who are finished pruning apples and peaches, some who have just started, and others who haven’t touched their orchards yet. We will see who fairs the best… I have concerns with what I would consider to be early pruning, combined with continued warm temperatures creating a perfect storm for when cold temperatures finally arrive. Heavy rains have plagued the area, with more than 13 inches recorded at the Oconee airport in January thus far.”

We hope everyone had a great Christmas and New Year! Please keep an eye on the Upcoming Events tab for several spring production meetings and conferences coming up around the state.

Midlands

Justin Ballew reports, “We’ve gotten a lot of rain over the last 30 days, including around an inch and a half late last week. The weather was warm in the afternoons for most of the week also. Our corps are going well, though spider mites seem to be picking up in strawberries. Mites are easy to forget about this time of year, so be sure to get out there and scout. We should have 3 branched crowns on our strawberries at this point, but we are a little behind in several fields. Caterpillar populations remain low and the brassicas we are harvesting look great. Sclerotinia white mold is showing up in some brassica fields following all the recent moisture we’ve had. This is a good reminder to use a crop rotation of at least 3 years.

Lalo Toledo reports, “We have seen ‘Sclerotinia stem rot’ on brassicas increase in the last couple days. This moist weather helps promote stem infections that spread rapidly downward to decay roots and expand upward wilting leaves, resulting in plant collapse. We have observed a white, cottony growth near the soil line. Disease development is generally favored by abundant soil moisture and temperatures ranging from 10-25°C (50-77°F). It is important to implement good sanitation practices and long rotations to non-host crops. Cultivate to help promote good soil drainage. Fungicide application are also available. Refer to Vegetable handbook. Remember to rotate fungicide groups.

Pee Dee Region

Tony Melton reports seeing spider mites in most strawberry fields. “Fall strawberries covered in hoop houses or just covered outside are doing well and producing well. Selling out the few remaining regrowth collards and greens. This week should be dry enough to start bedding land for spring greens to allow weeds to emerge and kill using stale-bed-culture. Stale-bed-culture is my favorite way to destroy most of the weeds before planting any crop.”

Bruce McLean reports, “Even though the calendar says January, it’s been feeling a bit more like April here lately. The remaining brassica crops look really good (for the most part). Cabbage, collards, turnips and broccoli are still in good supply. Pest pressure has been extremely low this season. Strawberries are looking very good as well. The recent heat is pushing blooms a bit. I haven’t seen anyone dragging the row covers out yet, so blooms are getting bitten on these coldest nights. No worries… they’ll be plenty more blooms to take their place. I’ve not seen any significant pests on strawberries, either.

The recent heat has really pushed the broccoli out. Photo from Bruce McLean.

Upstate

Kerrie Roach reports, “We’ve had cold weather along with lots of precipitation in the Upstate over the last few days. There were even some flurries up in the mountains. Pruning for apples is going to commence over the next few weeks. The SE Apple Growers Association Meeting is this week Tuesday and Wednesday in Asheville, NC, and many of our SC growers will attend.”

Dr. Matt Cutulle shared the photos below of a direct seeded collard weed control study. “Below is the untreated check (Left) and a plot treated with Treflan (Pre-plant incorporated) and Dual Magnum (Post-applied when collards are at least 3 inches in height). This is approximately 9 weeks after seeding. Main weed is corn spurry.”

Zack Snipes reports, “The mild temperatures and rain have helped our crops out. The collard crop is looking great for the Christmas and New Year’s harvest with very little insect or disease damage. Strawberries are looking good as well with excellent fall growth and color. Strawberry plants should be about the size of a baseball cap this time of year. Blueberry plants have turned a beautiful deep red color and are beginning to get some chill hours going into winter dormancy. I hope everyone has a wonderful holiday season spent with family and eating lots of SC GROWN products.”

Justin Ballew reports, “We had decent growing weather again last week. Steady rain fell all day Friday and we saw 6.5 inches at my house. Luckily, the sandy soil soaked most of it up. Growers are continuing to harvest brassicas and they look great right now (very little insect damage). We are still battling spidermites in some strawberries.”

Pee Dee Region

Tony Melton reports, “Fresh Market collards are selling rapidly. Many growers are re-growing the first cut collards of September/October to have them ready for second cut for New Years because they are running out of first cut collards. Turnip roots are getting large and need to be sold if tops are to remain. Turnip roots alone are a cheap commodity. The last of the processing turnips tops and mustard are being harvested this week and all that will be left is second cut collards to be harvested. Hopefully the rain helped to control spidermites on strawberries.”

Zack Snipes reports, “Strawberries have been planted in the Lowcountry. Some rain throughout the week has really helped them take. Already seeing deer tracks in fields without fencing. I scouted a few fields and found enough juvenile spider mites to warrant a spray. We need to stay on top of the mites this season. Please scout your fields and take necessary measures to manage them.”

Justin Ballew reports, “We had a few showers come through the midlands last week. Strawberry planting has wrapped up and the young transplants are getting established well so far, as we’ve had pretty favorable weather lately. Fall brassicas are looking great and worm pressure is still a little below average. Fall crops of cucumbers, tomatoes, peppers, green onions, eggplant, squash and zucchini are still being harvested.”

Broccoli head developing well. Photo from Justin Ballew.

Bruce McLean reports, “Brassica (cabbage, collards, turnips, broccoli, etc.) and strawberry planting has finished. The crops look very good. Okra and squash will finishing up soon. Downy mildew is still a challenge on squash. Brassica insect pressure has been relatively light, except for aphids which have been moderate in limited locations. Continue to scout regularly.”

Tony Melton reports seeing lots of worms and moths. “I have seen sweet potatoes stripped by stripped armyworms, armyworms, loopers and velvetbean caterpilars in greens, and millions of corn earworm moths in peas. Also false chinch bugs are loving the turnips, kale, and mustard. Strawberries are getting established. ”

Zack Snipes reports, “A few rain showers and some cooler temperatures have really helped out our fall crops. Collards, kale, and broccoli have really perked up this week and some early stuff could possibly be cut this week. Our worm pressure has not been terrible this year but that does not mean you can take a week off of scouting. Strawberries have gone in throughout the Lowcountry and are looking great after some cooler temperatures and rain. If you have not put up your deer fencing for strawberries, get it out ASAP. Each plant can be worth around $3, so one night of feeding can really cut into your bottom line.”

Brassicas have really perked up in the lowcountry. Photo from Zack Snipes.

Justin Ballew reports, “We got some much needed rain this past week thanks in part to Tropical Storm Nestor. This has our fall brassicas growing fast and looking great. We’re still seeing some whiteflies in brassicas, but the caterpillar numbers are a little lower for the time being. Lots of strawberries were planted last week and they are developing well so far. The rain and cooler weather has really been helpful in getting them established. Strawberry planting will finish up this week for the folks planting larger acreages.”

Pee Dee Region

Bruce McLean reports, “The recent rain from the remnants of Tropical Storm Nestor helped to improve dry soil conditions in the Pee Dee. This beneficial moisture should help the remaining cucurbit crops (yellow squash, zucchini, and cucumbers) and the okra crop through the final few weeks of the season. Planting of brassicas (collards, cabbage, kale, broccoli, etc.) and spinach are finished. Strawberry planting should be finished in the next week. Worm damage on brassicas has been light, but aphids have been plentiful in isolated locations. Be sure to scout your fall crops regularly.”

Okra crop is really starting to slow down, but quality is still good. Photo from Bruce McLean.

Tony Melton reports, “Still in the middle of harvesting processing sweet potatoes – not enough rain to size them up earlier, now having to wait for soil to dry and more rain is coming. Bacterial disease on turnips bad this year (maybe because of the heat), losing about 1/3 of yield because we’re having to harvest early. Also, reduced stand on greens from the beginning because of the excessive heat at planting. Also, bacterial soft rot is bad in the heat where irrigation and harvest equipment has spread through the fields. A lot of moths (Hawaiian webworm) flying in fields. We’re spraying once, which is more than usual (with Coragen and similar products) to keep larvae out of greens. Last of the pickling cucumbers are being harvested this week.”

Upstate

Mark Arena reports early harvest of pecans may begin soon. “Here are some tips for pecan management for the month of October. Prepare for harvest by mowing the orchard floor and keep it free of limbs and other debris. Maintain adequate soil moisture. Treat all “mouse ear” nickel deficiency noticed. Lime, zinc, phosphorus and magnesium can be applied if deficient. Scout and treat aphids, mites and pecan weevils as necessary. Apply preventative fungicides as scheduled and be aware of pre-harvest intervals for all chemicals applied.”

Statewide

Dr. Tony Keinath reports, “Growers who have “slacked off” on fungicide applications during the dry spell should resume biweekly or weekly fungicide sprays in areas that are or have received rain. For most fungal diseases, the amount of rain determines how severe the disease becomes. The more rain, the more fungicide sprays are needed. Note that many fungicide labels now state that the product may only be applied once every 7 days; 5-day spray schedules are going away.

Coastal Region

Zack Snipes reports, “Another hot and dry week in the Lowcountry. Non irrigated crops are really starting to suffer. Many farms are waiting on rain to plant fall crops. We are beginning to prepare for strawberry season but dry conditions are making it hard to lay plastic. Festivals, corn mazes, pumpkins, and haunted trails are in full gear in the Lowcountry.”

Justin Ballew reports, “Last week was hot, but temperatures finally dropped over the weekend. It finally feels like fall. Dry weather remains, though. A few areas got some light showers, but it didn’t amount to much. Growers have laid their plastic for strawberries and planting is approaching quickly. Caterpillars are still very active in brassica crops and we are seeing some whiteflies as well. Keep scouting and stay on top of the insects.”

Sarah Scott reports, “We have had spotty rain throughout the Ridge but conditions are still very dry. Cooler night temperatures are bringing some relief. Field preparation for new peach tree plantings are underway including soil fumigation. With the recent discovery of the root knot nematode, Meloidogyne floridensis, in fields in Edgefield County, growers can request a PCR test if nematode samples test positive for root knot nematodes.

Lalo Toledo reports, “Phytophthora blight on bell peppers has been found in Clarendon and Orangeburg County. Phytophthora blight on peppers is extremely damaging and can result in total loss of the crop prior to the first harvest. Proper fungicide applications and resistant cultivars can be used to suppress this disease. Sweet potatoes are being harvested, as well as eggplants. White-fly populations have been found in broccoli and mustard.
