| Abstract | ||
| The study was carried out to determine the effect of aquatic extracts of some plants including Myretus communis , Ocimum bacilium and Mentha spicata on the growth of pathogenic fungus Phytophthora infestans and to protect tomato plants from infection by this fungus. The results showed the ability of extracts in the inhibition of fungal growth at different levels of each extract and each concentration in same extract. Where the aquatic extract of Myretus at 5% caused the highest rate of inhibition of fungal growth and increased the germination percentage to 73%, and reduced the percentage of seedling damping-off to 4.4% as well as increase in fresh weight and dry of shoot and root, followed by the Mentha extract and Ocimum extract at 50% and 75% respectively as compared to the treatment of control (B). | ||
