| Abstract: | The botanic fungicide, which was made from the methol extracts of cottonseed meal and mineral, was used to prevent from wheat powdery mildew and cucumber downy mildew in field tests. The results showed that the inhibitory effect against cucumber downy mildew was 55.5 % after 1 week of spraying 500 - fold dilution; the infection indexes of wheat powdery mildew of wheat seedlings decreased by 28.22% after 1 week of treatment with 750- fold dilution and by 42.01% by treatment with 1000 - fold dilutions, respectively. |
