摘要
通过室内毒力测定和网室生物测定,筛选出6%三消丹(6%丙多·多)水分散粒剂用于防治水稻稻瘟病。经田间小区试验结果表明, 施用三消丹水分散粒剂60 g/667m2 防治水稻穗颈瘟发生,防治效果可达到70%以上,推荐剂量60 g/667m2,对水稻植株的生长安全。
Sanxiaodan (6% bingduo·duo) WG was selected to control rice blast through virulence determination in vitro and pot test in greenhouse. The result of plot trial in rice fields showed that it could effectively prevent the incidence of rice blast with above 70% of control efficiency and was safe to rice. The field dosage was proposed as 900g/ha.
