ABSTRACT
A greenhouse experiment was conducted to determine thiobencarb (S-4-chlorobenzyl diethylthiocarbamate) toxicity to IR-36 and RD-19 rice cultivars as affected by the time of NA (1,8-naphthalic anhydride) application. Both cultivars responded similarly to time and sequence of NA and thiobencarb application. Application of both NA and thiobencarb at planting was the least injurious to the plants and appeared to be the most promising treatment. NA treatment at planting followed by thiobencarb at 3 days after planting seemed a good alternative If simultaneous application is not possible. These results imply that the antidote must be applied at the same time or ahead of the herbicide to reduce if not prevent herbicide damage to rice.
