1%丙环唑·嘧菌酯颗粒剂防治辣椒立枯病田间药效试验

Field efficacy trials of propiconazol azoxystrobin 1%granule against Rhizoctoniasolani

[目的]明确1%丙环唑·嘧菌酯颗粒剂对辣椒立枯病的防治效果,并筛选出最佳田间防治剂量,明确对辣椒种子的安全性。[方法]依照《农药登记试验质量管理规范》,参考《农药田间药效试验准则(一)杀菌剂种子处理防治苗期病害》进行田间药效试验。[结果]1%丙环唑·嘧菌酯颗粒剂制剂用量为600、800、1000 g/m3时,防效分别为76.21%、81.13%和85.58%,高于对照药剂且对辣椒种子和幼苗安全,对周围作物安全。[结论]使用1%丙环唑·嘧菌酯颗粒剂在辣椒播种前,以制剂用量600~1000 g/m^(3)进行基质拌药1次,可以有效防治辣椒立枯病的发生,且对辣椒种子、幼苗及周围作物具有较好的安全性。

[Aims]This study aims to determine the control effect of propiconazol·azoxystrobin 1%granule(GR)on the blight of capsicum,to screen out the best field control dose,and to test the safety of capsicum seeds.[Methods]Field efficacy trials were conducted according to the‘Quality Management Standard for Pesticide Registration Trials'and the'Guidelines for Pesticide Field Efficacy Trials(I):Fungicide Seed Treatment for Control of seedling Diseases'.[Results]When the dosage of propiconazol·azoxystrobin 1%granule was 600,800,1000 g/m^(3),the control effect was 76.21%、81.13%and 85.58%,respectively,which was higher than that of control agents,and safe for seeds and seedlings of capsicum and surrounding crops.[Conclusions]Using the formulation of propiconazol azoxystrobin 1%granule to mix the matrix once at the dosage of 600-1000 g/m^(3) can effectively prevent and control the blight of capsicum,and has good safety for the seeds,seedlings and surrounding crops of capsicum.
