Antifungal activity of chitosan against Phytophthora infestans and activation of defence mechanisms in tomato tolate blight. Using bicarbonates for controlling late blight disease of potato plants under field conditions. ![]() In conclusion, the results of this study show that it is possible to reduce the dependency on copper in crop protection by using low copper dosages or natural products.Ībd-El-Kareem, F., & Abd-El-Latif, F. The best results were obtained with the formulation containing copper at low doses and leaf licorice extract. Under greenhouse experiments, all treatments significantly reduced late blight in comparison with water control plants. ![]() The results showed a remarkable inhibitory effect on hyphae growth and sporangia germination of the tested products. The disease severity for each pot was estimated. After 24 h, they were inoculated with a sporangial suspension of Phytophthora infestans. Tomato seedlings were transplanted into pots containing pasteurized soil and were then treated with the investigated products. The greenhouse trial was carried out on 5-week-old tomato seedlings cv. The in vitro tests consisted of evaluating both the development of oomycete colonies on an agar medium supplemented with the tested products at various concentrations and the inhibiting effect of products on sporangial germination. The effect of plant extracts, inorganic products, microorganisms and chitosan were investigated in vitro and in a greenhouse pot trial. In fact, due to its persistence and toxicity, copper appears incompatible with organic farming’s objectives of environmentally friendly farming. The aim of this paper is to explore appropriate alternative products to copper for the control of late blight disease in organic farming.
