甲酰胺磺隆与拌宝混用对甜玉米田杂草的防效

Efficacy of Foramsulfuron Plus Biopower for Weed Contol in Sweet Corn

探讨了甲酰胺磺隆+拌宝不同浓度配比对玉米田杂草的防除效果。试验结果表明,在玉米苗期,用甲酰胺磺隆与拌宝混用可有效地防除多种玉米田杂草,其中甲酰胺磺隆+拌宝165+1200g/hm2防除效果最好,药后40d对杂草的株数防效和鲜重防效分别为92.2%、95.8%,增产30.1%。

This paper discusses the efficacy of foramsulfuron used with Biopower at different concentration ratios for weed control in corn. When applied to corn in the seedling stage, foramsulfuron plus Biopower controlled several species of weeds. Foramsulfuron + Biopower at 165 + 1200 g/ha provided the best control, with weed stand and fresh weight reductions of 92.2 and 95.8%, respectively, 40d after application, and a crop yield increase of 30.1%.
