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.”
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.”
Sarah Scott reports, “Lower temperatures have brought a few light frosts to the area with scattered damage to tender vegetation. We continue to harvest broccoli, bell peppers, tomatoes, eggplant, sweet potatoes, spinach and collards.”

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.
