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 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 non-conventional treatment performed with an aqueous solution of 3.3% Allium cepa L. (GA6 = 8.11%) and 4% Allium cepa L. (GA2 = 13.42%), and the weakest (even weaker than in the case of the untreated control) under the conditions of treatment with Alcupral 50 PU (GA4 = 16.07%).
