Abstract

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