Title: Effects of Wettable Powder Mixed with Butachlor and Pyrazosulfuron for Control of Weeds in Transplanted Rice Fields
Abstract: To provide guidance for chemical weed management in broadcasted rice fields,trials were conducted to evaluate the effects on weed control and crop yield of a fertilizer formulation mixed with 28% butachlor and pyrazosulfuron WP.The results showed that 28% butachlor and pyrazosulfuron WP 226.8~525.0 g(a.i)/hm2 had good control effects on Echinochloa crusgalli(L.) Beauv,Monochoria vaginalis(Burm.F.),Rotala indica,Cyperus difformis L.in transplanted rice fields.The overall fresh control effects and density control effects were significantly higher than 60% butachlor EC and 10% pyrazosulfuron WP.The application of 28% butachlor + pyrazosulfuron WP significantly reduced the weeds absorption of nutrition and water,resulting in prominent yield enhancing.
