水稻纹枯病高效防治药剂的筛选试验

Screening of Effective Fungicides in Controlling Rice Blast

[目的]筛选防控水稻纹枯病的高效药剂。[方法]按照农药田间药效试验准则,研究防治水稻纹枯病常见药剂控病效果。[结果]6种药剂在试验条件下对水稻生长安全,以32.5%苯甲·嘧菌酯SC 600 mL/hm^2的病指防效最高。[结论]该研究为有效防控水稻纹枯病合理选用药剂提供理论依据。

[Objective]To screen effective fungicides for controlling rice sheath blight.[Method]According to the criterion of pesticide field efficacy test,the control effect of common fungicides on rice sheath blight was studied.[Result]All tested six fungicides were safe to rice growth under the experimental conditions,and the disease index of 32.5%Difenoconazole-azoxystrobin SC 600 mL/hm^2 was the highest.[Conclusion]The study provides basis for the rational selection of fungicides for the effective control of rice sheath blight.
