立枯清(38%福·甲)防治水稻苗期立枯病研究

Study on the Control of Rice Wilt at the Seedling Stage With Likuqing

立枯清(38%福·甲)是一种新型的防治水稻苗期立枯病药剂,水稻旱育苗防治立枯病试验结果表明,在药种比1∶200～1∶500之间防治立枯病效果为100%～89.9%,对水稻的出苗日期无影响,出苗率略有降低,是一种比较好的防治水稻苗期立枯病药剂。

Likuqing (38% thiram-metalaxyl) is a new type of fungicide for rice wilt control at the seedling stage. The experimental result of drought nursery raised seedling show that its controling effect for rice wilt reached to 100%～89.9%, with the ratio of the fungicide to seeds is 1:100～500. The result also show that this funogicide has no influence on emergence of seedlings, but the rate of seedling emergence is a little lower compared with control. It could be concluded that Likuqing is a good fungicide for rice wilt control at the seedling stage.
