摘要
The indoor toxicity determination for several chemicals were carried out on Septoria pini-putmlae andDothistroma pini. The resutts showed that Carbendazol, Zineb and Thiophanate-methyl had better effect of killingthe fungi. The field experiment indicated that Zineb wettable powder with concentrations of 1:200, 1:300 and 1:500had 79.2%, 67.2% and 59.7% control results respectively. The control results of 1:200 Carbendazol wettable powder and 1:200 Thiophahate-methyl wettable powder were 67.7% and 67% respectively.
