The EPA has granted an emergency use Section 18 for use of COUNTER 20G on cotton for management of nematodes and thrips.
Here is a comment from UGA Extension Pathologist, Dr. Bob Kemerait:
Please note the restrictions on the label for use of herbicides. Of significant concern is the potential for adverse interactions with specific herbicides (see notes on label). Dr. Culpepper is conducting further studies now to refine the potential for interactions. As one person associated with the product told me, “We have been super cautious with regards to limiting use of herbicides in conjunction with Counter 20G.”
Unfortunately, we do not have much of the data we would like to have in making recommendations for this product. I believe that most growers who use COUNTER 20G for nematodes will use a 6.5 lb/A rate.
