Abstract: In order to provide reference for chemical weed management in seedling-throwing rice fields, trials were conducted to evaluate the effects of % mefenacet + bensulfuron-methyI granules (pesticide-fertilizer mixture) on controlling weeds in s
eeding-throwing rice fields and on yield of rice. The results showed that % mefenacet + bensulfuron-methyI granules had good control effects on Echinochloa crusgalli(L.)Beauv,Cyperus difformis L.,Monochoria vaginalis (Burm. F.) in seedling-throwing rice fields,with %~% overall control effects, and significantly higher than 50% acetochlor EC and 10% bensulfuron-methyI WP. The application of % mefenacet + bensulfuron-methyI granules effectively improved the light and water-fertilizer conditions in fields, with significant yield-increasing effect.
