While many growers may be finalizing their cotton plans and getting planters ready for the field, it’s also a good time to start thinking about managing early season insect pests, especially thrips.
“In normal years, we usually have to overtreat 20-to-30 percent of our cotton acres on top of the seed treatments for thrips,” stated Angus Catchot, Extension entomologist with Mississippi State University. “But for the last two years, for a variety of reasons – maybe cooler weather, maybe residual herbicides holding the cotton plant growth back a bit – we’ve had to make multiple applications on up to 70 to 80 percent of the acres. That’s a trend that may be with us for a while.
