Control of Colletotrichum “causal agent of anthracnose in mango fruit (Mangifera indica L.)” applying Trichoderma metabolites
Article Sidebar
Main Article Content
Abstract
The use of controlling fungi for the control of phytopathogenic fungi is currently being widely applied as part of the organic agriculture process but also for the marketing of export fruits that are exposed to fungal diseases that cause significant losses. The objective of this work was to evaluate the control of Colletotrichum "causal agent of anthracnose in mango fruit (Mangifera indica L.)" by applying Trichoderma metabolites to determine the percentages of mycelial growth inhibition and germination inhibition. of the conidia of Colletotrichum sp. and control of Colletotrichum anthracnose lesions in mango fruit. In vitro evaluations were made applying antagonism of T. harzianum and T. viride against Colletotrichum sp. in dual tests and solution of Trichoderma metabolites against suspensions of Colletotrichum sp. conidia; and in vivo by applying Trichoderma metabolite solutions on mango fruit infected with Colletotrichum sp. The results show that Trichoderma, in vitro, as a fungal inoculum, and as a solution of metabolites, respectively inhibit mycelial growth and conidia germination of Colletotrichum sp. significantly; and in vivo as a solution of metabolites on the fruit of the mango control the anthracnose of Colletotrichum sp.; being the solution of metabolites of T. viride the one that exerts a greater control comparable to that of a biocontroller that can be used to control anthracnose in mango fruit, especially for export.
