Join us this Thursday (10/28/21) at 12:30pm for the next installment of our CUltivating SC Growers Series. This month Zack Snipes will be discussing the ins and outs of cover cropping. To register, click here.

Coastal Region

Zack Snipes reports, “We had a nice week of weather last week and are getting some rain this morning (10/25). Strawberry plants are arriving and growers will be busy putting in plants this week. I’ve gotten several calls about doing plant dips to prevent disease for the upcoming season. Most growers are using Zivion but it has been somewhat hard to come by so others are using Switch. We are dipping plants so crown rot diseases don’t wipe out our crop. Speaking of wiping out our crop…DEER. Get your fences up now BEFORE you plant. We see black rot on brassicas every season but it seems particularly bad this season. Cultural practices such as crop rotation, using clean seed and transplants, and spacing plants out can help with the disease. There are no products that will help with this disease. We had a great fall watermelon crop that will be wrapping up here shortly.

Justin Ballew reports, “We finally got our strawberry transplants in and most are now in the ground. We still have a few to finish up and we should be done this week. Even though it is cooling off this week, don’t forget to overhead water newly planted transplants for the first several days. Drip irrigation is often not enough in our sandy soil while the plants are trying to get established. Now is also a good time to go back through the field and check for plants that settled too much after transplanting. Gently pull them up to the correct depth and refirm the soil around them. If you are in an area with deer pressure, now is the time to put up deer fencing. Don’t wait until feeding has already begun or it will be even harder to keep the deer out of the field.”

Upstate

Andy Rollins reports, “We are still in process of planting our 2022 strawberry crop. Growers are looking closely for root diseases of plants as well as leaf disease. Many are concerned about the new disease Neopestalotiopsis (see this article). Growers need to be careful with cutoffs and bare-root planting. J rooting is a common problem. The L-shaped planting tool should be used to hold tips of roots, push plants to the proper depth, hold the crown above ground with the other hand, and push down. This last step was commonly being neglected on several farms. Roots should be straightened or cut off in the last step. We had a case of herbicide damage on turnips. Sulfentrazone (Spartan) is believed to be the culprit. This product builds in the soil, especially when used multiple years in a row. So, please be careful not to cause your own problem.”

This strawberry planting is looking good so far. Photo from Andy Rollins.

Sulfentrazone can build up in the soil over time and cause some plant damage. Be careful about using it in the same fields in successive seasons. Photo from Andy Rollins.

Don’t forget to check out the Upcoming Events page for all the meetings coming up over the next couple months. The next one is this Wednesday evening (1/27/21) from 6 to 8:30 and will be about tomato and pepper production. We hope to see you there!

Coastal

Rob Last reports, “Strawberry crops in the area are looking good with good crown development. We are seeing open flowers and some fruit set based on warmer conditions. These crops are cause for some concern as we are likely to see damage from forecast cold snaps. There is evidence of botrytis (gray mold) in crops on cold damaged flowers and fruit. Sanitation can really help to mitigate the spread of the disease. Spider mites remain active and in places are requiring treatment. Remember to avoid pyrethroids for mite control as these can flare mite populations.”

Zack Snipes reports, “The three components of the disease triangle are a conducive environment, the host plant present, and a virulent pathogen. With that being said; It has been pretty wet as of late, we have warmer weather coming this week, and I have seen pathogens in our fields. I fully expect some diseases to really take hold and start to spread this week. For strawberries, make sure to clean dead tissue (leaves, blooms, fruit, etc) and for other crops removal of dead tissue and a preventative fungicide application (conventional or organic) can really help you get ahead of the fight against diseases. Also, my pet peeve…get your deer fences up!!!! This is the time of year that deer run out of food (and corn piles) and will meander into your strawberries and eat thousands of dollars’ worth of profits.”

Justin Ballew reports, “This past week was a little warmer and more sunny, but not by much. Crops are still growing slowly as a result. I’m seeing a lot of deer damage in strawberry fields that boarder the woods. Nothing reduces yield potential in strawberries faster than deer. Once they start nibbling leaves off, those plants will always be behind and they’ll never yield the same as a healthy, undamaged plant. Keep in mind that wildlife in the field is also a significant food safety risk. Once we get into bloom, this will become a major concern. Fencing is the most effective means of keeping deer out of the field. Fencing doesn’t have to be expensive or permanent. Check out this publication.”

Look at all those stems where leaves used to be. The deer have set these plants way back and they will never catch up. Photo from Justin Ballew.

Sarah Scott reports, “New plantings of peach trees are going in along the Ridge. A weather station went up in Johnston at one of our variety trials this past fall and we are watching to see chilling hours accumulated. Currently we are at 714 chill hours and 43 chill portions looking at temperatures between 32 and 45 degrees. The upstate at the Musser location is sitting at 773 chill hours and 46 chill portions. It’s looking like we will have no problem meeting all of our chilling requirements for the season.”

Pee Dee

Tony Melton reports, “I keep finding more strawberry fields with spidermites. Some fields are damaged or devastated by deer. If you ever let deer get a taste of strawberry plants it is very difficult or almost impossible to stop them.”

Upstate

Andy Rollins reports, “Strawberry plants are doing well in the upstate of SC. Some plants are smaller than others mainly due to planting time. Growers need to look for uneven growth with in a field which can be indication of root rot. Also, some growers are spraying Rovral because of early dead blooms producing excessively high amounts grey mold. Some are using it with Captan others with Thiram. Thiram would give some deer deterrence. Growers need to be very careful with covers this time of year. They can force even more unwanted early blooms. Remember 18 degrees hurts crown 30 degrees kill blooms. So we are still in the protect plant time, not the protect bloom time. There are several farms planting peach trees now and still others finishing ground preparations. We also have a new pecan farm whose trees I was able to inspect and help with last minute details before planting this week. I hope and pray all of you stay safe amid the Covid19 pressure around us. The loss of a farming friend and leader of men, Mr. Ervin Lineberger will be greatly missed.”

Statewide

Dr. Matt Cutulle reports, “A good stand of fall cover crops will typically suppress most weeds. However, you may want to pursue herbicide options for cleaning up the weeds that have pushed through the cover crop canopy. If these cover crops act as buffers in fall vegetable crops, one has to proceed with caution regarding herbicide application. The best selective herbicide option for controlling broadleaf weeds in cereal rye would be a low volatility 2,4D or dicamba product ( the low volatility dicamba products may not be available right now). Enlist One is a 2,4D choline formulation. Apply the herbicide with a hooded sprayer using nozzles that produce coarse droplets. We are approaching cooler temperatures so the conditions do not favor volatility as much as they did in late spring/summer. If you have a clover cover crop and do not want to kill it, do not spray 2,4D. Using a labeled graminicide (clethodim or sethoxydim products) in clover will provide control of grass weeds that have escaped the clover cover. Remember to read the label and use appropriate surfactants with the graminicides for maximizing activity”

A good fall cover crop can suppress late summer weeds and early winter weeds.

Coastal

Rob Last reports, “Strawberry plants and cut offs are going into the ground in the area. Remember to check roots and crowns before planting and also supervise planting crews to ensure correct depth of planting is achieved. Caterpillar and whitefly on a range of fall crops, pressure remains high in the area so vigilance and regular scouting will be required to spot potential problems.”

Zack Snipes reports, “This past week was all about strawberries. I visited many farms and saw lots of plastic being laid. I checked many strawberry plants from a multitude of nurseries. Overall the plants look ok this year. I haven’t found any glaringly obvious root or crown rots and very little foliar issues in our plugs and cutoffs. Overall the plants are on the smaller side and I hope for a good fall growing season so they can size up a bit before going into the winter. I saw, on a few farms, issues with calibration and equipment for fertilizer distribution. If you need help calibrating or calculating fertilizer rates, please give me a call. I would be more than happy to come give you a hand. I hate to even mention it but I am already seeing deer tracks in strawberry fields…if you need it…”

Imagine that…deer tracks in a strawberry field…Get up your fences! Photo from Zack Snipes.

Midlands

Justin Ballew reports, “Strawberry planting has wrapped up in the midlands and the earliest transplanted fields are already pushing out new leaves. This cooler, damp weather is much better for getting strawberries established than the dry, 95 degree days we saw this time last year. Be sure to go back through the fields shortly after planting to ensure the plants are set at the proper depth. If any were planted too deep or settled too much after the first overheard watering, gently pull them up to the proper depth and refirm the soil around them. This should be done before new roots start to form. Also, get ready for deer! it doesn’t take them long to find newly planted strawberries.”

Pee Dee

Bruce McLean reports, “Strawberry planting is going full pace. Much of the acreage was planted in the last half of last week. The remainder will be planted this week. So far, the transplants look very good. Acreage is up compared to last year. Brassicas are (for the most part) looking good. Insects have not been much of an issue – minimal caterpillar occurrences, occasional aphids, and some grasshopper damage. Some fields have experienced some plant stunting and plant losses due to persistent wet soil conditions (root rot). Die-off really started to show on affected plants with last week’s heat. Some growers will begin harvest next week.”

Tony Melton reports, “Very little insect and disease problems on greens. However seen a lot of B and Mg deficiencies. Continues to harvest sweet potatoes yield is very good. Some late Butterbeans and peas are planted. Most strawberries are planted already some deer damage.”

Upstate

Kerrie Roach reports, “Late season rot issues have sent some apple growers looking for more answers with fungicide resistance testing. Apple pathologist Sara Villani’s lab at the MHCREC in Mills River, NC is conducting tests to look at resistance to specific modes of action(MOA) and fungicides in Apple production. Harvest in apples is about 80% complete with only a few varieties left to pick.”

Coastal

Zack Snipes reports, “Summer crops are all but about done. The afternoon thunderstorms, humidity, and heat have just about finished off the tomato and watermelon crops. Growers are getting fields ready for the fall season now. Consider putting up deer fencing now before crops are planted.

Midlands

Justin Ballew reports, “We got some more rain early in the week and the sky was overcast most of the week. Downy mildew finally showed up here in cucumbers. Even though it’s been found all over the coast, it took a while to make it this far inland this year. The dry weather we had most of the month of June may have had something to do with that. Anyone growing cucurbits from now through the fall definitely needs to be applying preventative fungicides. Lots of fields are transitioning from spring crops to fall crops right now. We’re still picking sweet corn, tomatoes, peppers, eggplant, squash, zucchini, cucumbers, etc.”

Lalo Toledo reports, “Sweet potatoes are in the ground and thriving. Please be aware of any pest activity and disease activity. Weeds are becoming a problem, especially in organic operations. However, there are several options to suppress weeds. Please contact your extension agent for information on chemical and cultural practices. Hemp is having trouble taking off with so much heat and weeds are gaining ground on it. Peppers are doing great with some minor bacterial lesions.”

Pee Dee

Tony Melton reports, “Poured rain every day last week – awful. Processing peas are ready to harvest but cannot get a dry period to burn down to harvest. Need to get second crop processing peas planted before August if fields will ever dry out – don’t forget to control thrips early and do your best to keep deer out of fields. Processing tomatoes & peppers are being harvested. Pickling cucumbers are continually being harvested and replanted. Sweet potatoes are planted, most have been laid-by, many have vines covering beds, and some are starting to size potatoes. We may have some insect damage on roots since it is difficult to get bifenthrin applied and plowed-in. Hopefully, the Lorsban will control insects, and since it is too wet to plow until the rain can wash the bifenthrin into the soil to keep the sun from degrading it. Don’t forget the boron on sweet potatoes.”

Upstate

Kerrie Roach reports, “Peaches are the showstopper this week in the Upstate! Even with what appears to be late cold damage causing split pits and some varieties not to ripen, the peach crop is still booming. Apples are maturing on schedule and growers should begin harvesting early varieties over the next few weeks. With limited and spotty rain events over the last seven days, irrigation has been vital for vegetable producers…. but heat and humidity (despite the overall lack of rain) has increased the need for fungicide cover sprays, as we’ve seen various fungal activity picking up across the board.”

All of SC is now under a “Home or Work” order from Governor McMaster. Farming is an essential industry, so Commissioner Weathers has issued this Notice of Essential Food and Agricultural Employee form that farms may fill out for each employee certifying them as an essential employee. Employees should keep this form with them while commuting to and from work.

Coastal

Zack Snipes reports, “We had a great week of weather last week in the Lowcountry. I am extremely concerned and curious to see what things look like after the powerful line of storms we had Monday morning. I feel like we will see lots of damage to taller crops and in areas where there were no windbreaks. If plants suffered in the storm and have open wounds from sand, wind, or tying twine, then expect to see more disease. It would be a great time to get out some fungicides and bactericides to prevent spreading of diseases. As of Friday, our crops looked great. I have been seeing LOTS of damage by our biggest pest in the Lowcounty…DEER. Fencing is cheap compared to the amount of money you are losing to browsing damage. Check out this publication on fencing.

Midlands

Justin Ballew reports, “The weather was nice last week and crops really responded. Brassicas and sweet corn are both growing really fast. Strawberry production really picked up last week too. Luckily, sales at produce stands have been really good lately. We had a really strong storm come through early Monday morning and we expect to see some water damaged strawberries as a result and probably some diseases like black rot on brassicas. Strawberry growers, be sure to sanitize the plants well so damaged fruit won’t become inoculum for Botrytis and anthracnose.

Sarah Scott reports, “The peach crop is coming along nicely. Some high chill hour requiring varieties are developing at an uneven rate but only time will tell if there will be a good crop on those. Strawberry production is picking up. A couple of cooler nighttime temperatures may have slowed progression a bit but harvests are still on the rise. Field crops like spinach, kale, and broccoli are performing well. Some cucurbits being planted as well as tomatoes as labor needs are filled.

Blossom blight caused by the fungi, Monilinia fructicola. Extended bloom and lots of rain during winter months made ideal conditions for infection. Refer to the 2020 Peach Management Guide for information on treating and preventing spread of brown rot. Photo from Sarah Scott.

Pee Dee

Tony Melton reports, “Awful infestation of early season diamondback caterpillar on brassicas like collards/cabbage most likely due to the overwintering on brassicas like radish in cover crops. When these crops are terminated for summer cropping these insects and other insects like yellow-margined beetle invade vegetable production fields. Also, cover crops containing brassicas should not be used in vegetable production fields because they increase diseases like bacterial soft rot and sclerotinia, which are tremendous problems in all types of vegetable crops.

I hope all strawberry growers got their ripe fruit out of their fields before this storm – if not a lot of fruit will most likely be discarded. Some rain was needed hope not too much falls – in S.C. when it rains it pours. Most summer crops are planted and we did get some wind damage and sandblasting causing stunting but no frost damage in the Pee Dee. The first plantings of processing tomatoes, peppers, and cucumbers are in and after this rain more will be quickly following. Spring brassicas are loving this rain.”

Upstate

Kerrie Roach reports, “It was confirmed that a tornado touched down in Seneca, SC early this morning around 3:30am. Reports of damage to agricultural operations have been limited, but there is certainly significant damage to business and residential structures. Apple and peach crops are looking good right now. We have many farmers market operations who will be replanting/reseeding after last night’s heavy rains.”

Andy Rollins reports, “We have been trapping high numbers of Oriental Fruit Moths in pheromone traps in peach orchards in upstate SC weekly. Numbers have been much higher in our late season varieties. We are assisting growers with correct timing of spray applications directed at egg hatch. We are also encouraging growers to rotate insecticide classes to prevent failure of the pyrethroids if this hasn’t already occurred. Dr. Brett Blaauw UGA/Clemson peach entomologist has been directing the effort aimed at reducing damage from this pest.”

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.

Pee Dee Region

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. ”

Coastal Region

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.

Midlands

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.”

Collards are looking great after the rain and cooler weather. Photo from Justin Ballew.

Sarah Scott reports, “Cooler temperatures and much needed rain are giving a boost to fall crops including collards, cabbage and broccoli. Bell peppers, tomatoes, squash, broccoli, sweet potatoes are still being harvested as well as hemp. Strawberry plants have been going in over the past couple of weeks.

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.”

Dr. Tony Keinath reports, “A new technical bulletin published online by Clemson University’s Land-Grant Press will help watermelon growers choose tactics to manage Fusarium wilt. Options include partially resistant varieties, delaying transplanting until soil has warmed, grafting, applying fungicides at transplanting, and winter cover cropping with vetch. See: Keinath AP. Integrated Management for Fusarium Wilt of Watermelon. Land-Grant Press by Clemson Extension. 2019; LGP 1022.

Coastal Region

Zack Snipes reports, “Strawberries are going in or will be going in very shortly here in the Lowcountry. I want to remind everyone how important it is that deer fencing is put up. Ideally the fencing should be put up BEFORE the strawberries go in the ground. I see hundreds of plants each year destroyed by deer. Assuming the value of that plant is around $3 (1.5 lbs berries per plant and $2 lb), it doesn’t take losing a lot of plants to really feel the financial loss. Please read an article I wrote about setting up and maintaining an inexpensive deer fence here.

Deer feeding damage can cause significant yield loses to strawberries.

Midlands

Justin Ballew reports, “The weather felt more like fall this past week, but still no significant rain. The very first strawberries have been planted in the midlands with a lot more planting expected this week. The first plants were set just before the weather cooled down and the heat really took a toll on them. 95 degrees just isn’t good for strawberry transplants. The current weather should be much more favorable for planting. Be sure to set plants at the proper depth and overhead water transplants adequately. Take a look at this Strawberry Growers Checklist for some good tips for fall strawberry management.”
