Abstract:
Taking Fulvia fulva as material,the effect of toxicity of boscalid and pyraclostrobin against Fulvia fulva were studied by spore germination method,and this mixture was tested in the field trials.The results showed that the mixture of boscalid and pyraclostrobin with the ratio of 2∶1 exhibited obvious synergistic effects against Fulvia fulva,with synergistic ratio 1.94.Under the dose of 240-300 g a.i.?hm-2,the control effect of the mixture (2∶1) against tomato leaf mould in the field was 81.96%-89.09%,which equal to difenoconazole 10% WG at the dose of 120 g a.i.?hm-2.The mixture of boscalid and pyraclostrobin display characteristics of action from both fungicides,enhancing their acivity to,and might be helpful to delay the development of resistance by target fungus.
