试验示范结果表明,41%甲硫·戊唑醇悬浮剂对水稻纹枯病有较显著的防治效果,并能促进水稻增产。用药量以900~1 125 m L/hm2为宜。一般要求在纹枯病发生初期和水稻破口抽穗期各施药1次;1季水稻防治1次的宜在水稻破口抽穗期用药,用药量以1 125 m L/hm2左右为佳。
The experimental demonstration results show that 41% methothiazole tebuconazole suspension has a significant control effect on rice sheath blight and can promote rice yield. The dosage of 900 ~ 1 125 m L / hm2 is appropriate. The general requirements in the early blight and rice breach heading stage of the application of 1; 1 season rice prevention and treatment of 1 should be used in the heading of rice breaking heading, the dosage to 1 125 m L / hm2 or so better.
