| Abstract | ||
| Faba bean is a legume that is economically important throughout the world. One of the global diseases, chocolate spot disease, causes losses in crops that range too modest to catastrophic. Botrytis cineria is one of the main causes of this disease. To control the effects of the biotic stress brought on by the occurrence of disease, certain phenolic acids were sprayed topically. Some chemical catalysts such as Nano zinc-oxide (ZnONPs) with concentration (10, 50 and 100 ppm), also the fungicide (Diacin) with the recommended dose (100L/fed) and control, were applied in this study to evaluate its effectiveness in controlling chocolate spot disease. The severity of the disease was substantially reduced by every chemical inducer that was tested. Additionally, they improved the treated plants' defense mechanism by raising the activity of antioxidant enzymes (catalase in comparison to the corresponding control. Comparing plants infected with Botrytis fabae to healthy leaves, the latter showed the highest values of antioxidant activity (p < 0.05). According to the results, ZnONPs could be used to reduce the effects of the chocolate disease. | ||
