春雷霉素·噻唑锌40%悬浮剂防治水稻稻瘟病试验初报

A Preliminary Report of 40% Kasugamycin-Zinc thiazole SC on Controlling Rice Blast

田间药效试验结果表明,春雷霉素.噻唑锌40%悬浮剂对水稻稻瘟病有较好的防治效果,其药效随用药量加大而显著上升,其中第2次药后14d 40mL/667m2的校正防效达80.91%,极显著优于对照药剂噻唑锌20%悬浮剂120mL/667㎡的校正防效,与对照药剂春雷霉素2%液剂80mL/667m2的校正防效相当,且安全性好,因此可以在生产上加以推广应用。

Field efficacy trials indicated 40% Kasugamycin-Zinc thiazole SC had good effect on controlling the rice blast. Disease preventing efficiency grows with dose increase, with a efficiency up to 80.91% when 14d after the second spraying, which significantly better than 20% Zinc thiazole SC, but had no significant differences with Kasugamycin 2% AS. More importantly, Trifloxystrobin-Tebuconazole40% SC was safe to humans. A regional application can be developed.
