Zack Snipes reports, “After a long Thanksgiving nap, I was able to waddle out in the fields and look at some strawberries. We have had some really good strawberry growing weather especially considering most folks got their plants out somewhat late this year. We need some cold weather to slow them down a bit in places. I am seeing a tiny bit of plant collapse and death in some spots within the fields. It is very important to send these plants into our lab to get a positive identification of the pathogen. Phytophthora crown rot and anthracnose crown rot can cause similar symptoms but are managed completely different. For information on how to submit a sample during COVID times, click here. I am also keeping my eye on a good bit of leaf spotting in some fields to make sure its not the new disease, Neopestalotiopsis. I don’t think we have it yet, but being proactive is better than being reactive. More information on that disease can be found here.”

Justin Ballew reports, “The mornings were nice and cool last week and we saw light frosts in a few more areas. We’ve been getting a fair amount of rain also. This has the brassica crops looking great. Caterpillar populations are still fairly high. Don’t give up on scouting as it gets cooler this week. Diamondback moth caterpillars and adults can survive for several hours at temperatures well below freezing, so a few nights in the upper 20’s is unlikely to affect them, other than slowing down their life cycle a bit. Don’t give up on scouting for mites in strawberries either. Even though we’ve had some wet weather lately, they’re still out there.”

Tony Melton reports, “We still have some sweet potatoes in the ground. Greens are growing well except for bacterial diseases. Some diamondback are hard to kill. We are trying everything.”
Upstate
Kerrie Roach reports, “With a low of 30 degrees Fahrenheit predicted tonight, and 26 degrees F predicted tomorrow night(Tuesday), growers in the Upstate should be making preparations for a hard freeze event. Wind speeds from 10-25 miles per hour have begun, and are expected to continue through Tuesday. So make sure any protective measures are held down tightly!”
We have added a new resource under the “Resources” section. On the right side of the page, you will find a link labeled “Plant and Seed Supplier List.” This is a list of reputable nurseries and seed suppliers that growers in SC regularly work with. If you know of a good nursery or seed supplier you would like to suggest adding, just let us know.
We would also like to take the opportunity to wish everyone a happy, healthy, and safe Thanksgiving!

Rob Last reports, “Strawberry crops continue to develop well with minimal pest and disease pressure so far. Fall vegetables are progressing towards market. We are continuing to see pest pressure from caterpillars and a few isolated aphids have been spotted during scouting. As we progress towards the holiday season, scouting of crops remains of vital importance to catch insect infestation and disease progression early for treatments to be effective.”
Zack Snipes reports, “The week of wet weather two weeks prior prevented folks from getting out in the fields to spray for insects. I am seeing lots and lots of worm damage, particularly the diamond back moth. We need to get ahead of this pest so that we have good looking greens for the New Years Market. There are some very good products that we can use but knowing which ones to use and when to use them is where Clemson Extension can help. If you have swiss cheese plants, then give us a call to help out. The strawberry crops looks ok so far this season. The warm weather has really helped later seeded/transplanted crops. I am seeing some die off/rot in root crops in lower lying areas of fields.”

Justin Ballew reports, “Temperatures got a little cooler last week, with frost showing up in some low lying areas, mostly north of Columbia. Early season growth of strawberries has been impressive so far. As warm as it’s been this fall, early season row covers probably will not be necessary this year unless plants were transplanted late. Caterpillar population size and damage seems to be on the rise in brassicas. I saw some fields this past week where insecticide applications weren’t made in a timely manner nor were materials rotated properly and the caterpillar populations have really gotten out of hand. Call us if you have questions about controlling caterpillars and never use broad spectrum insecticides when caterpillars are your primary pest!”
We’ve had good early season strawberry growth so far. Photo from Justin Ballew.How many diamondback moth caterpillars and pupae can you count on this leaf? This is a key reason why weekly scouting, timely spraying, proper insecticide rotation, and avoiding broad spectrum insecticides for caterpillar control are so important. Photo from Justin Ballew.

Tony Melton reports, “Still a lot of sweetpotatoes in the ground. The bacterial diseases (Xanthomonas and Pseudomonas) on greens are raging havoc. Rotation is the best control I have found. I hate swinecress when it comes to greens -it takes over. Yellow margined beetle is getting worse in greens and spreading all over the state – Imidacloprid is a good control without killing beneficials.”
Upstate
Kerrie Roach reports, “Things have certainly slowed down in the field the last few weeks. Apples are mostly finished for the season with ‘Arkansas Black’ being the last variety to be picked. Most growers will keep roadside markets open until Thanksgiving and then call it a quits for the season. Now begins the prep for next year with educational meetings, pesticide certification credits, soil testing, land prep and more. Make sure you are checking the events page for the upcoming trainings.”
Pestalotia leaf spot and fruit rot are emerging diseases that were discovered last season on strawberries in the southeast. This could potentially have an impact on SC strawberry production, though the extent is yet to be determined. Please see these two publications (UF and UGA) and be on the lookout. If you suspect you’ve found Pestalotia leaf spot or fruit rot, please let your local Clemson Extension Agent know.

Zack Snipes reports, “Strawberries are planted and for the most part looking good. I am seeing some spider mite damage on plug plants. Get out and scout and treat as needed. In some areas we had 4 or more inches of rain last week which made fields sloppy, unable to be harvested, and tough to spray. Get out and look for worms in brassica this week.”

Justin Ballew reports, “Last week was warm and wet, as expected. We had a good amount of rain Tuesday evening and Wednesday. I expect to see foliar diseases increase this week. Pecan harvest continues in the midlands. While yields have been very good, nut quality isn’t quite where we want it. This is most likely from the trees not getting enough water at certain times during the summer when the nuts were filling. The weather is forecast to get cool this week. It there should happen to be a frost, that would be the end of the fall squash and tomato crops.”

Tony Melton reports, “We have seen some flea beetles/larvae feeding on strawberry transplants and yellow-margined leaf beetle has been bad on brassicas. Some crops have been drowned by the rain. Harvest or row-cover warm season vegetables before the frost to avoid damage. Harvesting the last of the butterbeans and peas this week. A lot (500 or more acres) of sweet potatoes are still in the ground and harvest will begin again after the soil dries.”
Upstate
Andy Rollins reports, “Still inspecting strawberry plantings across the upstate. Look for uneven growth on either side of the bed and also in the row. Placement of drip tape depth and distance from plants is very important as is proper planting. Uneven up and down growth can be indication of root rot or other problems too, so look carefully. Unusually wet weather from recent hurricanes has given us conditions very favorable for fungal Botrytis growth. Dead tissue is very susceptible to being colonized first. Use of Captan, a protectant fungicide would be advised as long as conditions remain favorable.”

Zack Snipes reports, “It seems like we experience fall and summer in the same day this time of year. I visited a few farms and saw residual damage from whiteflies (silver leaves, virus, and stunted plants). The good news is that overall populations of whiteflies are down this week. The armyworm numbers are still high in a lot of crops so keep an eye out for those. We have lots of good products for them so choose something other than a group 3 or 4 insecticide. I have seen some white mold (Sclerotinia sclerotiorum) in some brassica crops this week. I have some great reports from strawberry fields and other not so great reports. If you have issues, please call me so we can fix them before they get out of hand.

Justin Ballew reports, “We had some very warm afternoons this past week. The air has been much drier as well. Young strawberries are responding well and have put out a good amount of new growth. Weak plants caused by J-rooting and deep planting are making themselves evident now. The drier air has allowed some growers to get a handle on the disease issues that have plagued us for the last few weeks. However, there is lots of warm, wet weather in the forecast, so plan your fungicide applications accordingly and rotate modes of action. Other crops are still growing well and we have folks picking tomatoes, squash, beans, and various brassicas.
All the strawberry plants in this small area were J-rooted and subsequently died. Photo from Justin Ballew.Brassicas are looking good in the midlands. These collards were just recently cropped for the first time. Photo from Justin Ballew.
Sarah Scott reports, “Patchy frost brought an end to some fields of summer crops like squash and zucchini, however most areas did not see damage from cold temps. Cole crops are progressing nicely but insect populations are high this fall, including aphids and imported cabbage worms. Strawberry plants have gone in and are taking root and getting established.”

Tony Melton reports, “Getting dry. Hope get some rain later in the week. Greens are growing very fast with warm weather. Frost burned the very tops of some crops like sweet potatoes, tomatoes, peas but did not really hurt them much. Very little grasshopper pressure for some reason this fall.”
Rob Last reports, “Strawberry planting is mostly complete in the area. Plants received from nurseries have been very good this year and establishment is progressing well. In fall vegetable crops Southern army worms continue to be present and numerous. Whiteflies in fall vegetables are beginning to reduce. Disease pressure remains relatively low.”
Zack Snipes reports, “Strawberry planting continued last week. Bare root plants look good going into the ground. Stay on top of workers to plant them correctly. I saw some patches with “J” roots or long roots that went to the bottom of the hole and back out. Those plants will die or produce considerably less yield than properly planted plants. Also, I have seen and heard reports of spider mites on plug transplants. Check your fields and get out miticide this week if you need it. Fall growth is very important as well as knocking out the existing spider mite populations. Remember that the threshold for spider mites is 4-5% of the leaves with a population. And lastly, I have seen AWFUL disease on purchased transplants. If you purchase transplants and they have disease on them, DO NOT plant them. The plants will never produce like they should and you are inoculating the rest of your crops and land with that disease.

Justin Ballew reports, “Young strawberries are growing well so far in the midlands. We’ve had good weather for getting the plants established. We are starting to see some spider mites already, so don’t forget that we need to be scouting regularly as soon as the plants are in the ground. If you plan to cover your strawberries for a couple weeks in the fall, getting rid of mites should be priority #1. Other crops are doing well also, though we are seeing high numbers of caterpillars and diseases like black rot and Alternaria on brassicas have really been ramping up.”

Once populations reach the threshold of 4% infestation, treatments need to be made in a timely manner to keep spider mites from hanging around throughout the winter and into the spring.

Tony Melton reports, “First time I have seen large numbers of yellow-margined beetle in Orangeburg County – we had to treat 1 out of 10 fields for them. If possible do not use a pyrethroid on young greens it will encourage worm and aphid problems. Still seeing a lot of boron and Magnesium deficiency in greens, mostly because farmers are not liming properly, using sul-pho-mag, or using premium fertilizers with minor elements. Spray with boron and many applications of Epsom salts and the greens will eventually grow out of the problem. Like always, swine cress and corn spurry are awful weeds in greens – to control I recommend using a stale-bed culture technique before planting. We still have butterbeans, peas, and cucurbits in the ground – hope frost stays away until after Thanksgiving.
Upstate
Kerrie Roach reports, “High winds, heavy rains and now cold over night temperatures have laid down a gauntlet for growers in the Upstate over the last week. Many growers in Oconee County lost power from the remnants of hurricane Zeta for anywhere from 1-4 days. Apples are just about finished with mainly Yates and Arkansas Blacks left to pick. Apple growers concerned with fungicide resistance should contact Kerrie to pull Bitter Rot samples now to be sent to the shared lab at NC State.”
Andy Rollins reports, “Finishing up strawberry planting in the upstate. I’ve been inspecting farms and assisting some growers with planting different types of plants they weren’t used to planting. Unlike the pictured transplants some are a little smaller than normal but appear to be healthy at this point. Colder weather is a slight concern as we need decent growing conditions to get them rooted in well. Some may need to use row covers to keep strawberry plants growing during the first 30 days in the ground if temperatures stay low. Peach growers are putting down fall herbicides still and some are preparing to do delay blooming. This involves waiting till at least 50% of the leaves are off of the trees before applying a liquid form of ethylene. Other stipulations are also important regarding temperatures after application. If it is your first time trying this, speak with your county agent to get the correct method.

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.

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…”

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.”

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.”

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.”
Rob Last reports, “As we approach the time where strawberry plants will be delivered I would urge all growers to inspect plants before planting. Whiteflies continue to be numerous along with caterpillars in fall brassica crops. Scouting as always will remain very important.”
Zack Snipes reports, “Hide ya collards, hide ya tomatoes, they eatin’ everything! The Southern Armyworm is wreaking havoc on crops in the Lowcountry. The Southern Armyworm is a heavy feeder on a wide range of crops. They are dark in color, with yellow to cream colored horizontal lines and a reddish/orange head. If inspected closely, one will find a yellow “Y” shape on their head. I see this pest in fields with a variety of crops as well as weedy field borders. We have a full offering of insecticides to battle this pest but remember to rotate insecticides each time you spray. We are also finding some Tomato Yellow Leaf Curl Virus (TYLC) in tomato. This virus is transmitted via the whitefly. Strawberry cut-offs and plugs are going in. Be sure to inspect roots and crown before planting. Give me a shout if you need an extra pair of eyes to check them out.”

Justin Ballew reports, “We had a welcome light rain towards the end of last week and the temperatures cooled off nicely. Strawberry planting has begun and is progressing well. Remember to supervise planting crews closely to make sure plants are being set at the proper depth. Now is also the time to get deer fences up. Once the plants develop new leaves, it won’t take the deer long to find them. We’re still seeing a fair amount of powdery mildew and downy mildew in cucurbits and anthracnose in pepper. Caterpillar populations remain high in brassicas as well.
Strawberry cutoffs are being watered in after being transplanted. Following transplanting, cutoffs need to be overhead watered for at least a week to keep the plants from drying out while new roots get established.

Tony Melton reports, “Greens are loving cool weather and growing well. Very little disease or insect problems. Large numbers of armyworm moths in some green fields but they are not feeding on greens but on the purslane, pigweed, and other weeds – control the weeds. Sweet potatoes are being harvested as quickly as possible. Many strawberries are planted – already seen some deer damage. I have seen large fields of peas without a pea left on top of the plants – from deer damage. Pickle harvest is finished for the year. Cool weather is slowing bean and pea growth and production. Agri-tourism is flourishing because people want to get out of the house.”
Rob Last reports, “Crops are generally looking very well to press with some welcome rain benefiting fall crops. Whitefly and caterpillar numbers are increasing. With a few foggy mornings happening over the last week be on the look out for foliar disease pressure to increase given the increase in leaf “wetness”. Plastic and, where applicable, fumigants are applied, ready to begin strawberry planting. Just a reminder to check plants carefully before planting for crown rots and early foliar pest and disease activity.”
Zack Snipes reports, “We had another wet week in the Lowcountry with 2.5 inches of rain collected at the Coastal Research Station in Charleston. Things are looking great for strawberry planting in the next few weeks. Be sure to check your plants and roots before you plant them. Many issues can be solved before plants go into the field. Fall brassicas, squash, lettuce mixes, and root crops are growing and looking great. We still have whiteflies on many farms. On most of these farms, spring fields were not terminated once the crop was done which could have led to the explosion of whiteflies we have been seeing this fall.”

Justin Ballew reports, “Last week was warm and we saw a heavy dew most mornings. We also had some pretty decent rain come through over the weekend. This warm, moist weather has disease increasing fairly aggressively on some crops. Powdery mildew and downy mildew on cucurbits are pretty rough right now. Pecan shucks are opening and nuts are falling from the earlier varieties like Pawnee and Excel. Strawberry planting should begin this week.”

Tony Melton reports, “Still planting processing greens mostly kale and collards because they are a little more resistant to winter cold. Greens are rapidly growing. I have already seen some Reflex damage from carryover from last year. Personally I think it affects roots and keeps them from taking up nutrients and the damage is very similar to magnesium and boron deficiency – so I always recommend applying Epsom salts and boron to combat the problem and it usually works. Strawberries are going into the beds. Since many are using vapam or k-pam, make sure that enough time is allowed for the fumigate to escape before planting. Many do not fumigate anymore so don’t forget velum, nimitiz, and majestine are available for nematode control.”
Zack Snipes reports, “The cooler weather and lots of rain have brought out the diseases. I saw some watermelon diseases last week including gummy stem blight. We need to protect our foliage just a few more weeks to finish off those melons so keep at the spray programs if you can. Whiteflies continue to hammer us in all crops this fall. Strawberry planting is just about upon us. Rains and wet ground have slowed some farms from laying plastic. Remember that preplant fertility and herbicides are critical to spring success. Spartan and Devrinol are the only two preplant herbicide options this late in the season. Other products require a 30-day wait period. Let me know if you want me to come check your strawberry plugs before you plant them.”

Low spots in fields may remain wet and this could lead to potential problems. Peppers are looking good as well as eggplant and late squash. Brassica crops are having some issues with aphids causing leaf curling. Pecans are beginning to fall as well. Scab seems to be particularly bad this year, most likely because of wet weather during critical spray times for fungal management in late June and July.

Tony Melton reports, “Greens are growing fast with cool temperatures; however, beans, peas, pickles, and sweet potatoes have slowed down with these temperatures. Most sweet potatoes need to find a home. We are using a lot of potassium phosphide to keep down root rot especially on greens. Most growers also use it as a dip for strawberries transplants or put through drip system as soon as they plant. Getting ready to plant strawberries as soon as the transplants get here.”

Kerrie Roach reports, “Clear skies since Tuesday with cool fall temperatures at night and warm days has consumers looking for all things fall. Growers with pumpkins, gourds, mums, corns stalks, and/or anything fall related have been busy keeping up with demand. Agritourism demand/opportunities has picked up significantly in the last few weeks. Apples are in peak season with Stayman being one of the current varieties available.”
Andy Rollins reports, “Upstate peaches are finished up for the year but muscadines are still being harvested although slowing some and strawberry planting is in full swing. I was called to examine poorly growing peach trees at an upstate farm. The majority of trees were dying from the most devastating disease of peach ‘Oak Root Rot.’ There was gumming at the base and I was fully expecting a greater peach tree borer problem but closer examination and cutting of the below ground bark revealed the Oak Root Rot fungus growing at the base of the trees. When pushing your older peach trees up be sure to examine the main roots for the sign of this disease which is the white to yellowish fungal growth deep inside of the bark below the soil level. There are a few other fungi that can have a similar symptom but they tend to grow just on dead tissue and don’t grow as deep into the wood of the tree. There are some things you can do about it, but proper identification comes first.”
