摘　　要：为探明当前常用水稻稻瘟病防治药剂的防效差异,以7种杀菌剂为试验对象,参照农药田间药效试验准则开展了对稻瘟病的田间防效评价。供试的7种杀菌剂均对稻瘟病有一定的防治效果,其中40%嘧菌酯可湿性粉剂(WP)、75%三环唑WP和32.5%苯甲·嘧菌酯悬浮剂(SC)对水稻稻瘟病的防治效果较好,防治效果均超过80%。值得注意的是30%稻瘟·戊唑醇SC对水稻生长具有一定抑制作用,造成水稻抽穗困难。这些结果为水稻稻瘟病的化学防控提供了科学参考依据。In order to find out the difference in the efficacy of the commonly used rice blast control agents,7 fungicides were used as test objects,and the field control efficacy of rice blast was evaluated in accordance with the guidelines for field efficacy trials of pesticides.The results showed that all the 7 fungicides tested had a certain control effect on rice blast,among which azoxystrobin 40%WP,tricyclazole 75%WP and difenoconazole·azoxystrobin 32.5%SC had a better control effect on rice blast,with the control effect exceeding 80%.It is worth noting that isoprothiolane·tebuconazole 30%SC had a certain inhibitory effect on rice growth,causing difficulty in rice heading.These results provide a scientific reference for the chemical control of rice blast.
