- EVALUACIÓN DE LA ACTIVIDAD ANTIFÚNGICA DE Trichoderma asperellum Samuels ANTE PATÓGENOS FÚNGICOS QUE AFECTAN AL CULTIVO DE LA SOYA ( Glycine max L.) Ariel Cruz Triana Deyanira Rivero González Benedicto Martínez Coca Anayza Echevarría Hernández Aida Tania Rodríguez Agrociencias Fusarium sp Biological control Cercospora kikuchii Phakopsora pachyrhiz Among the factors that adversely affect crop yield of soybean ( Glycine max L.) the incidence of pests and more specifically pests caused by fungi stand out. Numerous fungicides in increasing doses are used in the phytosanitary control of these agents, and in most cases the desired control is not achieved, a situation that increases production costs and significantly reduces farmer benefits. Based on these antecedents, the objective was to evaluate fungal diseases of highest incidence in soybean crop and antifungal activity of Trichoderma asperellum Samuels. The experiment was carried out at the Basic Scientific and Technological Unit “Los Palacios”. The in vitro antagonism of T. asperellum strains by the method of dual culture in Petri dishes was assessed. Besides, the distribution and the attack index of soybean crop key diseases under field conditions when the crop was treated with the Ta. 13 strain of T. asperellum were evaluated. Generally, T. asperellum showed a high potential for the biological control of evaluated diseases, significantly reducing its distribution and infection percentage and it provoked that the number of pods per plant were higher. 2017 artículo científico 1819-4087 https://www.redalyc.org/articulo.oa?id=193254602002 https://www.redalyc.org/journal/1932/193254602002/ https://www.redalyc.org/journal/1932/193254602002/html/ https://www.redalyc.org/journal/1932/193254602002/193254602002.epub https://www.redalyc.org/journal/1932/193254602002/movil es http://www.redalyc.org/revista.oa?id=1932 Cultivos Tropicales application/pdf Instituto Nacional de Ciencias Agrícolas Cultivos Tropicales (Cuba) Num.4 Vol.38
