Testing the Anti-Fungal Effect of Aqueous Extract of Allium cepa L. in Potato
Abstract
According to FAO-STAT data updated until 2020, worldwide, Europe ranks first in terms of the proportion of potato production at global level (41.90%), followed by Asia (39.60%), America (12.70%), Africa (5.30%) and Oceania, which only has a contribution of 0.50% in the world potato production. The present study aims to emphasize the effect of aqueous extract of Allium cepa L. in fight against Alternaria solani Sorauer in potato. Over the entire experimental period, the best results were obtained with the conventional and non- conventional treatments performed with metiram 80% aqueous solution of 4% Allium cepa L. (GA = 12.20%, and GA = 13.80%), and the weakest (but much lower compared with the untreated control) under the conditions of treatment with 2% Allium cepa L. aqueous solution (GA = 15.90%).
