| Abstract: | Combination toxicity potential and synergistic effect of macozeb and dimethomoph on Pseudoperonospora cubensis was tested by leaf disk floating method in the laboratory.The result demonstrated that the macozeb and dimethomoph mixtures at the ratio of 12.8∶1,8.9∶1,6.7∶1 and 5.3∶1 had additive effect.The synergistic ration(SR) was 1.06 and 1.21.The mixtures at the ratio of 4.3:1 and 5.3:1 had synergistic effect.And the SR value was 1.54 and 1.56,respectively.It was concluded that the rate of 5.3∶1 was the best mixing proportion.In this test some useful data for further research was also provided. |
