Abstract
The inhibitive effects of garlic bulb crude extract on Fulvia fulva in tomato were studied both In vitro and pot experiment. The results indicated that, the inhibitive rate to spore germination reached 96.08% and to mycelia growth increased to 100% when the concentrations of garlic extract reached to 40mg.mL-1 and 80mg.mL-1, respectively. The preventive and curative effects were 85.32% and 83.49% in young tomato leaves In vitro, 76.50% and 68.91% in function tomato leaves In vitro, 69.92% and 69.36% in bottom tomato leaves In vitro when the concentration of garlic was 80mg.mL-1. In pot trial, the preventive and curative effects on tomato seedlings reached 82.19% and 79.37%, respectively when garlic concentration increased to 160mg.mL-1, however, the higher concentrations of garlic bulb crude extract did not show any bad effects on growth of tomato in this experiment. In conclusion, garlic bulb crude extract is effective and environmental friendly for control of leaf mold in tomato caused by F. fulva.
