摘要

Although herbicides provide effective weed control, some herbicides may pose serious health and environmental threats. Thus the bioefficacy and the persistence of three formulations of a herbicide, anilofos [GR (granules), W/O (water in oil emulsion), and EC (emulsifier concentration)], at 300, 450, and 600gha(-1) as pre-emergent applications were evaluated in transplanted rice (Oryza sativa L.). All of the formulations enhanced the rice grain yield by 50% over weedy check and the grain yield was greatest in the 30% EC treatment applied at a 450gha(-1) rate. Phytotoxic symptoms of anilofos were not observed with any of these formulations on the transplanted rice. Terminal residues of anilofos in the soil and mature rice plants were below the maximum residues limit (MRL, 0.05mg/kg) in the soil, grains, and straw treated with the various formulations of anilofos. Study showed fast degradation of anilofos in the soil and rice plants.
