Protecting Corn from Herbicide Injury by Seed Treatment

Abstract
The use of 1,8-naphthalic anhydride, at 0.5% by corn (Zea maysL. ‘501D’) seed weight, eliminated most of the corn yield loss caused byS-ethyl dipropylthiocarbamate (EPTC) at 3.4, 6.7, or 10.0 kg/ha. The seed protectant partially reduced the moderate corn yield loss fromS-ethyl diisobutylthiocarbamate (butylate) at 9.0 kg/ha. This seed protectant provides a new approach to increased weed control while maintaining selectivity in the production of corn.
