25%丙硫克百威悬浮种衣剂对水稻干尖线虫病的防效

Efficiency of 25% Benfuracarb Flowable Concentrate for Seed Coating to Rice Nematodiasis Caused by Aphelenchoides bessyi

25%丙硫克百威悬浮种衣剂每千克种子4mL、8mL包衣水稻种子,对水稻种子的发芽、出苗没有影响,水稻苗高显著高于对照,实际产量、穗长、每穗实粒数都显著高于不用药处理,该种衣剂各处理对干尖线虫病的防效均高于95%杀螟丹可溶性粉剂6000倍浸种处理的防效。

The test results revealed there was no negative effect to the rice germination rate and seedling emergence treated by 25% benfuracarb flowable concentrate for seed coating （FSC） at the dosage of 4 mL and 8 mL per 1 kg seed. However, the height of seedling, actual yield, panicle length and filled grains per panicle were all higher than the control. The effectiveness of all the treatments to rice nematodiasis was much higher than that of 95% cartap soluble powder treated by 6000 fold and employing seed soaking methods.
