Difenoconazole·azoxystrobin: Control Efficiency on Anthracnose,Safety and Effect on Crop Quality

To select effective and safe insecticides to control anthracnose, the authors conducted field trials. The results indicated that after difenoconazole·azoxystrobin were applied for 7d and 14d, its control effect of on bitter gourd was the best. Comparatively, the control effects of difenoconazole·azoxystrobin on strawberry and cucumber were also ideal. The research indicated that difenoconazole·azoxystrobin had better and durable control effect on anthracnose, which was an ideal insecticide against anthracnose in strawberry, bitter gourd and cucumber, in the same time, difenoconazole·azoxystrobin could control diseases, increase production and improve quality in strawberry production. The suggested dosage is 450-600 mL/hm2 in production.
