1986
Cabanilla, H.C.
All the rates tested resulted in better control of annual weeds compared to those of standard herbicides. Results also showed that pretilachlor applied 2 and 4 days after seeding at 0.30, 0.45, and 0.60 kg ai/ha were safe to direct-seeded wet sown rice and gave substantial yield increases over other times of application including those of standard herbicides. The optimum suggested rate and time of application is 0.30 kg ai/ha applied 3 to 5 days after seeding
