| 摘 要： | 对5种不同药剂进行了室内孢子萌发、雨水冲刷和田间药效试验。结果表明:5种供试药剂中20％三环唑·异稻瘟净WP和30％稻瘟灵乳油对防治水稻稻瘟病有较好的效果,其对稻瘟病的孢子萌发有强烈的抑制作用,孢子萌发率仅为 0．33％～1％;耐雨水冲刷时间为1 h,田间防治效果可达98％左右,能较好地防治水稻穗颈瘟的发生。

| Abstract: | Five pesticides were tested to investigate spore germination rate in door, tolerance to scouring by rain and control effects in rice field. The results show that 20% of tricyclazole and IBP and 30% of isoprothiolane have better effects for controlling Magnapothe grise in rice field. Three pesticides strongly control spore germination (only 0. 33%~1. 0% of spore germination rate). The time of tolerance to scouring by rain is 1h and the control effect is up to 98% in rice field. |
