Weekly Field Update – 11/23/20

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!”

Pee Dee

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.”
