Evaluación de dos fungicidas para el control de Moniliasis (Moniliophthora roreri) en cultivo de cacao en la Parroquia Enokanqui, provincia Orellana.

Abstract

In Enokanqui parish, Orellana Province, exist lack knowledge on good agronomic management and efficient fungicide uses to control moniliasis in cocoa crops by farmers due at scarce technical advice from public institutions. Therefore, the research objective was to evaluate two fungicides with different mechanisms of action into control Moniliophthora roreri cocoa crops (Theobroma cacao). The methodology implemented had a qualitative and quantitative approach, an open field experimental type, a completely randomized design was used with four treatments, three replicates each, data were taken from six plants at random for each one, with a total eighteen plants per treatment. In this work, variables evaluated were: number healthy ears, number diseased ears, moniliasis incidence percentage and cost analysis. By means this methodology, was determined by initial moniliasis incidence in crop 50 percent different frequent evaluation after 60 days it was considerably reduced: treatment 1 (Tebuconazole) presented 6.5 percent, treatment 2 (Azoxystrobin) 6.77 percent and treatment 3 (Tebuconazole plus Azoxystrobin) 4.83 percent. In this context, it is concluded the best treatment was Tebuconazole plus Azoxystrobin, which achieved a reduction considerable of moniliasis, being more effective and eventually economically profitable by farmer.
