蓝莓拟茎点霉枝枯病药剂防治试验

Fungicidal test against Phomopsis twig blight of blueberry

选6种绿A生产可用杀菌剂对拟茎点霉Phomopsis vaccinii进行室内毒力测定,结果表明:抑菌作用从强到弱的顺序为吡唑醚菌酯,腈苯唑,咯菌腈,苯甲·丙环唑,氟啶胺,嘧菌酯;从中选4种药剂进行田间药效试验,结果表明:吡唑醚菌酯防效73.6%,最好;咯菌腈防效50.71%,较低。

The indoor toxicity of six fungicides of Green A to Phomopsis vaccinii,pathogen of twig blight of blueberry,was tested to select effective fungicides. The result indicated the efficacy of inhibition against Phomopsis vaccinii was Pyraclostrobin Myclobutanil Fludioxonil Difenoconazolepropiconazole Fluazinam Azoxystrobin. Among them four fungicides were tested in the field,the results showed that Pyraclostrobin had the best control effect of 73. 6%,the contool effect of Fludioxonil was the lowest,which was 50. 71%.
