| Abstract: | The fungistatic effects of prochloraz,fludioxonil,tebuconazole,iprodione and procymidone on tomato Fusarium wilt were evaluated in this study.The concentration and proportion of compounds with mycelium growth-inhibition effect on Fusarium oxysporum were screened.The results showed that prochloraz and fludioxonil had significant inhibitory effect on the growth of mycelium.The inhibition rate of 0.1μg·mL-1 prochloraz and fludioxonil on Fusarium oxysporum were 73.8%and 48.7%,respectively.EC50 was 0.02μg·mL-1 and 0.17μg·mL-1 respectively.When the concentration of 0.1μg·mL-1 of prochloraz was mixed with fludioxonil,the inhibition rate was 91.1%.When the volume ratio was 2:8,it showed the significantly inhibitory effect.The results provide a theoretical data for the scientific and rational use of chemical fungicide,and provide important information for controlling tomato fusarium wilt as well. |
