Contribution to the study of the effect of fungicides on the growth of fungi with agricultural interest in El-Oued region

Abstract

The aim of this scientific research is to study the effects of antifungals and their effectiveness to eliminate the widely spread fungi that threaten the products of El-OUED State, especially Alternania, Botrytis, and Rhizoctonia. We have selected many samples from El-Oued, which are: potatoes, beans, peas, zucchini, salad, carrots, and tomatoes. We have grown it in the media PDA and Sabouraud, and we selected samples that showed results in the first stages of cultivation, which are: potatoes, carrots, tomatoes, and salad. They contain a variety of fungal species, with fungi in particular: Alternaria, Rhizoctonia, and Botrytis. We use for this study and in order to prove the effectiveness of the fungicide used and the optimal and least harmful concentration on plants and on human health, later on, the method of diffusion and the method of tablets, so that we conclude later that the most effective of the resistance is the latnif-itna TACHIGAZOLE + VALETTE, followed by TACHIGAZOLE and lastly by VALETTE. The reduction in fungal growth ranges from 50 to 100 %. We conclude that to reduce the fungi that affect the growth of vegetables and fruits in our agricultural stores, we need means of protection and prevention, with the use of fungicides with the aforementioned notifications and instructions without excessive use of them.
