Time Of Naphthalic Anhydride Application And Its Influence On Thiobencarb Selectivity In Rice

Abstract:

A greenhouse experiment was conducted to determine thlobencarb (S .. 4•chlorobenzyl diethytthlocarbamate) toxicity to IR-36 and RD-19 rice cultivars as affected by the time of NA (1,8•naphthallc anhydride) appllca• tion. Both cultivars responded slmllar'ty to time and sequence of NA and thlobencarb application. Application of both NA and thlobencarb at planting was the least Injurious to the plants and appeared to be the most promising treatment. NA treatment at planting followed by thlobencarb 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.
