| Abstract: | In this test,40% myclobutanil suspension,45% difenoconazole microemulsion & mancozeb and 50% diniconazolc were used to control pear scab in field.The results showed that their control effect was significant.At the initial occurrence stage of pear scab,using 60,204.5~225.0 and 40.0~50.0 a.i.mg/kg of the three fungicides respectively could let the control effect reach to more than 75%.Therefore,they were the ideal fungicides against the pear scab. |
