二硫氰基甲烷对水稻干尖线虫的防治效果研究

Study on the activity of methylene bisthiocyabate in controlling rice nematodiasis caused by Aphelechoides besseyi

水稻干尖线虫是水稻上最重要的寄生线虫之一,为研究二硫氰基甲烷对其的防治效果,本研究利用二硫氰基甲烷浸种处理对水稻干尖线虫病进行了田间防效试验。结果表明,10%二硫氰基甲烷EC和95%杀螟丹WP浸种处理对水稻干尖线虫病的防效均在84%以上,但10%二硫氰基甲烷EC处理的防效较后者更好;两种药剂处理对水稻产量的影响差异显著,产量均明显高于对照。

Aphelechoides besseyi is one of the most important nematodes on rice. In order to study the activity of methylene bisthiocyabate against rice nematodiasis, the field trails were conducted to test the efficacy of methylene bisthiocyabate in controlling this disease. The result demonstrated that,the control efficiency of 10% methylene bisthiocyabate EC and 95% cartap WP on stem tip nematode disease of rice were both above 84%, and that of 10% methylene bisthiocyabate EC was better. Morever, there was significant difference in rice yield treated by 10% methylene bisthiocyabate EC and 95% cartap WP, the rice yield treated with these two pesticides was significantly higher than that of CK.
