Field Update – 11/11/19

Midlands

Justin Ballew reports, “The weather was a little cooler this week. The soil is cooling down also and is causing some purpling at the tips of the leaves of brassicas (a sign of phosphorus deficiency).  Roots have a hard time taking up nutrients in cold soil, so make sure your fertility is adequate. Caterpillar populations are still relatively low. We’re still seeing a few whiteflies, but their numbers seem a little lower this week also. Strawberries are looking great so far. We are about done with the fall crops.”

The soil Monday morning (11/11) was just under 50 degrees.  This will cause root growth and nutrient uptake to slow.  Photos from Justin Ballew

Sarah Scott reports, “There have been several nights where temperatures dipped into the low 30s and we have had a few frosty mornings along the Ridge. Pepper plants are beginning to come out and late summer/fall crops wrapping up. Broccoli continues to be harvested along with kale, spinach, sweet potatoes and collards. Peach growers are preparing their orchards for planting new trees.”

Pee Dee Region

Tony Melton reports, “Last week, I found Clubroot on collards in a home garden in Florence and the plant problem clinic confirmed.  This is clubroot an awful disease of brassicas (greens, cabbage, etc.).  It was first found in SC in 2015.  That farm has a voluntary quarantine to keep it from spreading.  Please do not move plants or soil and cause it to spread.  It will stay in the soil for a long time (almost forever) and has the capability to destroy the brassica industry in SC.  Brassica and sweet potato harvest are at full speed because of the possible cold damage this week.

Field Update – 11/4/19

Statewide

Dr. Matt Cutulle cautions growers to be careful with late planted greens. “If getting out late with greens planting I would be careful with applying treflan pre-plant herbicides, as cold soil temperatures can facilitate injury.”

Coastal Region

Zack Snipes reports, “We are finishing up with summer crop harvests of cucumber, squash, and beans and harvesting fall crops like broccoli, collards, root crops, and lettuces. The rains and, at times, cooler weather have helped our fall crops. This past week I found some really cool beneficial insects in our Lowcountry brassica fields.  When scouting take note of any beneficials in your fields and know that they are providing lots of pest control for you.  Black rot in brassica has started showing up pretty regularly with the recent rains and lower temperatures.  Crop rotation, using clean seed and transplants, and sanitation (removing of diseased tissue) can help with control of this disease.  Many farms are seeding cover crops this time of year. Cover crops like clover can be grown to increase soil biomass, produce nitrogen, suppress weeds, and provide nectar and pollen for our beneficial insects.”

Justin Ballew reports, “We got some rain from thunderstorms last week and the weather has turned significantly cooler since. We are seeing a few spidermites on strawberries. Keep an eye out for those. We don’t normally see a lot spidermites this early, so don’t let them catch you not paying attention. Caterpillar populations are still low on brassicas and disease has been relatively low also. A few false chinch bugs have been reported on mustard and turnip. We’re cropping kale and collards and still picking some last minute fall squash, zucchini, peppers, eggplant, and tomatoes.”

Pee Dee Region

Tony Melton reports, “Bacterial leaf diseases of brassicas have been terrible this fall, maybe due to heat we had early  – processing greens had to be harvested early to meet grade.  I have found millions of  False Cinch Bugs on brassicas especially turnips – imidacloprid is a good control without killing beneficial insects.  Farmers (especially row crop farmers) need to be rotating from products containing chlorantraniliprole to other active ingredients – I have noticed a reduction of the length of control with these products.  Frost is here – protect.

Field Update – 10/28/19

Coastal Region

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.”

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.”

Field Update – 10/21/19

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.”

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.”

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.”

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.”

Coastal Region

Zack Snipes reports, “Cooler days and nights have really helped out our crops as of late.  Fall planted brassicas are taking off and looking good.  Fall watermelons are being harvested this week and look good overall. I have seen more cucumber beetle damage on the rind of watermelons lately.  While there is nothing wrong with these melons, this damage can impact the marketability of melons.”

Lalo Toledo reports, “Eggplant with symptoms resembling Cercospora leaf spot were found in Clarendon and Orangeburg county. A calendar-based protectant fungicide spray program combined with cultural practices can help reduce losses from Cercospora Leaf Spot. Cabbage whiteflies were also found in broccoli fields. Preventative application of insecticides to manage whiteflies is the best tactical management option. Refer to the vegetable handbook for recommendations.”

Upstate

Kerrie Roach reports, “Nighttime temperatures are finally indicating that fall might be on it’s way despite continued daytime highs in the 90’s. Currently listed in moderate drought with no rain in the extended forecast, the upstate is literally baking. The apple crop as a whole looks good, but red varieties are not coloring because of the heat, picking is about two weeks ahead of schedule, and with the lack of rainfall, moisture content is very low.”

Andy Rollins reports, “Muscadines are continuing to sell well in the upstate and are very high sugar compared to normal.  We are finishing with ‘Fry’ but still have ‘Supreme’ and ‘GrannyVal’ being harvested.  The crop will finish sooner this year because of higher than normal temperatures this month.  So if you wantem’ you better gettem’ because they’ll be gone soon.”

Dr. Tony Keinath reports, “Watermelons with symptoms resembling cucurbit leaf crumple virus (CuLCrV) were found at the Coastal REC after Hurricane Dorian. Whiteflies were present before the hurricane, so they did not arrive with the hurricane. Laboratory confirmation is in progress. Preventative applications of insecticides to manage whiteflies is the best management option. CuLCrV also affects squash, pumpkin, and cantaloupe.

Justin Ballew reports, “It was hot and dry early in the week, but we got some rain Thursday and Friday and temperatures are a little cooler now. Irrigation was running a lot in the first part of the week and some crops wilted in between waterings.  Keep an eye out for diseases now that moisture and humidity has returned. Diamonback moth caterpillar numbers seem up be picking up in places as well.”

Sara Scott reports, “It’s been hot and dry along the Ridge with no significant rainfall this past week. Fall fertilizer applications are going out in the peach orchards.”

Pee Dee Region

Bruce McLean reports, “Here we are in mid-September waiting for cooler temps, but having to endure some persisting summer heat. Luckily, the forecast is for some cooler weather about mid week. Muscadine harvest is coming to a close. Carlos and Noble grapes had good yields, this year. Doreen muscadines harvest should be just about to wrap up. Sweetpotato harvest is just getting geared up. Okra is still being harvested in good volumes. Cucumbers, yellow squash, and zucchini are a little light right now, but should be more plentiful in a few days. Peas and butterbeans are still available in limited supply. Fall planting of collards, cabbage, and other cole crops are being done now. Strawberry planting should be starting shortly.

Tony Melton reports, “Processing sweet potato harvest has begun.  Pickling cucumber harvest continues.  Brassicas have been slowed in growth and lost some stand due to the excessive heat – hope it cools down.  Processing spinach was delayed by heat, but planting has now begun.

 

 

Field Update – 9/9/19

Coastal Region

Zack Snipes reports, “Hurricane Dorian caused some damage, but it could have been a lot worse.  There are some trees down and some fields are flooded.  We’re still figuring out the extent of the damage.  Be sure to take lots of pictures for insurance.  Remember, all produce that was flooded cannot legally be sold and should be destroyed.  I’ll send out damage paperwork to growers in the low country soon.

Midlands

Justin Ballew reports, “Areas west of Columbia got just a little bit of wind and almost no rain from Hurricane Dorian.  We’re still picking muscadines and summer planted squash, eggplant, cucumbers, and tomatoes.  The cooler temperatures and recent rain has greatly increased disease pressure.  We’re seeing lots of bacterial spot and speck in tomatoes, black rot and ripe rot in muscadines, and various leaf spots in hemp.  Stick to your disease programs.  Fall brassica planting continues as does strawberry land prep.

Tony Melton reports, “Too wet to harvest sweet potatoes or pickling cucumbers.  Water is standing in some fields.  The closer the beach, the worse it is.  It’s time to plant spinach.  Much of the collards, turnips, kale, and mustard were planted and up before rain started.  If not up before the rain, seed could be washed away.  Many waited until after the rain to finish planting.

Upstate

Kerrie Roach reports, “Apples are in full swing. Growers are picking ‘Gala’, ‘Golden Delicious’, ‘Early Fuji’, ‘Mutsu’, and ‘Granny Smith’ varieties. Croploads look better than expected thus far, and seem to be about 2 weeks ahead of typical ripening due to the heat and drought. Muscadines are starting to come in to the markets along with the last bit of summer crops. Many of the smaller farmers markets are slim with produce right now because of the transition to fall crops.”

Andy Rollins reports finding some severe cases of anthracnose in late peppers. “The bright orange colored powdery substance are 1000’s of spores of the fungus Colletotrichum.  Leaf symptoms are not evident, just the obvious fruit lesions.   Hot rainy weather has persisted in the mountains and lack of good airflow caused this to be a major problem for some growers.  Even under the best spray program these problems can still exist if conditions for the disease are favorable enough.  Although some variety differences have been noted none are highly resistant to this problem.  A good spray program and good sanitation in keeping fruit picked is essential for the best control possible.

Justin Ballew reports, “This past week felt a little like fall.  We had some scattered showers and the temperatures cooled down a bit, especially in the mornings.  Hemp is blooming well and we are seeing some caterpillars feeding on the buds in some areas.  Fall brassicas are still being planted and the young plants are looking good so far. Beans, squash, zucchini, muscadines, eggplant, and tomatoes are being harvested.”

Pee Dee Region

Bruce McLean reports, “On most years, the beginning of muscadine harvest occurs right around the Labor Day weekend. This year was no different. A few weeks ago, there were some concerns that a few vineyards may have been experiencing early ripening due to this summer’s heat. Luckily, the heat broke a bit, and the grapes were able to hold on for a timely harvest. So, harvest of juice/wine grapes began earlier this week. Carlos and Noble varieties’ volume looks very good. Doreen is still a little ways out, and needs a few more days of ripening. Harvest will likely be pretty steady for the next couple of weeks. Fresh market muscadines are still coming off in good volumes. Strawberry growers are busy putting down plastic and getting beds ready for planting. Strawberry planting is just a few weeks away. Other produce available in good volumes are: late peas and butterbeans, cucumbers, squash, zucchini, and canary melons. The start of sweetpotato harvest is not too far away.

Coastal Region

Dr. Tony Keinath reports, “Phytophthora crown rot was observed on bronze fennel in a home landscape (mine) in Charleston. Fennel apparently is a new host for Phytophthora  (species not identified). Foliar symptoms include a progressive yellowing, starting with the older leaves. Symptoms on the lower stem and leaf sheath are a water-soaked, “greasy” rot. It is very likely that Florence (green, edible) fennel also is susceptible. Potassium phosphite products are the only fungicides registered for post-transplant applications on the leafy vegetables crop group that includes fennel.”

Sarah Scott reports, “Peaches are wrapping up around the ridge. Broccoli plants are still going in for fall harvest. We have had rain in the last week which has been a nice break on irrigation systems.”

Pee Dee Region

Tony Melton reports, “Last of pickling cucumbers have been planted.  Collard, kale, turnips, mustard, etc. planting in full swing with both transplants and direct seeding.  Bed prep for strawberries has begun.  Getting late to order strawberry plants. Fall blackberry harvest is continuing.   Sweet potato harvest will begin soon.  Double cropped processing peas are starting to flower.  Butterbeans planted for fall production are starting to flower.”

Upstate

Kerrie Roach reports, “The last few peaches are being picked this week in Oconee County. The apple harvest is coming along nicely, ‘Early Fuji’ and ‘Golden Delicious’ apples will start to be picked this week. A spotty hail storm in Long Creek last week has caused some damage across the orchards, but is very localized. Summer market vegetable growers are wrapping things up with some of the Farmers Markets closing at the end of August. With rain & cooler weather forecasted, disease and weed management will be a continued battle for growers.”

Coastal Region

Dr. Tony Keinath reports, “Phomopsis blight is showing up on eggplant at the Coastal REC. On susceptible cultivars, like ‘Black Beauty,’ the disease starts as leaf spots; later in the season stem cankers and fruit rot appear. Although several fungicides are registered on eggplant, none are specifically labeled for Phomopsis blight. Aprovia Top and Priaxor might give some control; more testing is needed before a definite recommendation can be made.”

Justin Ballew reports, “Last week we had some scattered rains, but some areas remain bone dry.  Irrigation is running a lot in those areas.  Muscadine harvest has started and so far, this is the largest yield we’ve seen in recent years.  Squash, zucchini, eggplant, cucumbers, and tomatoes are also being harvested. Quality looks good, but volume is down a bit in some areas.  More fall brassicas are being planted and strawberry growers are just starting the process of prepping their fields.”

Pee Dee Region

Bruce McLean reports, “Much of the upper Pee Dee Region received beneficial rains late last week. This helped to drop temps back to about normal, following the excessive heat from a few days earlier. On most crops, the rain really helped to push production again. Late season cucumbers, squash, zucchini, and okra are looking good. Canary melons are looking excellent. Volumes on these crops are good. Last week’s heat did take a toll on watermelons, though. Volumes are significantly down from the prior week and are likely winding down for the season. Muscadines are a bit varied across the region. In some locations, ‘Carlos’ and ‘Noble’ (wine and juice varieties) are getting very close to harvest, while other vineyards are ripening a bit slower. Harvest on the most mature wine and juice muscadines could begin as soon as next week.

Mark Arena reports seeing pecan scab. “Pecan Scab fungus is a weather dependant disease. There are varieties/cultivars that exhibit tolerance to this disease as shown below in the photos. Observed in Picture #1, we see both the nuts and foliage are showing signs of infection (the brown lessions). Picture #2 shows no sign of disease on either the nuts and/or foliage at the present time. Pecan scab can go undetected for days before the lessions appear, therefore, it is imperaitive to use a preventitive fungicide program to insure nut production.
