Abstract:
Soil were sprayed by different concentration of ethanol to study the effect of the concentration of ethanol solution and processing time on two soil-borne pathogens，Fusarium oxysporum and Phytophthora capsici.The results showed that ethanol solutions all had significantly suppression on the Fusarium oxysporum?and Phytophthora capsici in soil.The numbers of the two pathogens detected in 1.0%,2.0%,3.0% were less than the control group as well as the 0% concentration group at the time of 5,10,15,20,25 d and the differences reached a highly significant level.The numbers of the pathogens were the least in 3.0% concentration group.The processing time also had important effect.It was the best for Fusarium oxysporum after 20 days that the inhibition rate reached the maximum value，which were 92%，82%，67% for 3.0%，2.0%,1.0% concentration group respectively.It was the best for Phytophthora capsici after 20 days that the inhibition rate reached the maximum value，which were 83%，78%，62% for 3.0%，2.0%,1.0% concentration group respectively.
