Weekly Field Update – 10/19/20

Coastal

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.”

Midlands

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.

Pee Dee

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.”
