| Abstract: | The toxicity of 5% allicin EW to three kinds of cotton pathogens as Rhizoctonia solani Kuhn.,Fusarium moniliforme Sheldon.,Fusarium oxysporum F.were assayed in the laboratory using growth velocity method and their EC 50 were calculated as 19.4 mg/L,7.1 mg/L,20.6 mg/L,resp.The results showed that The activity of allicin to three pathogens can inhibit all of the three fungus effectively. The experiment results will be benefit to application of 5% allicin EW as fungicide to cotton diseases. |
