Evaluación de planes de manejo para el control de (Peronospora sparsa) en mora de castilla (Rubus glaucus benth)

Abstract

The blackberry is a fruit of great commercial interest within our national market, it is one of the crops that supports more than 12,000 families, however its production is affected by the excessive attack of downy mildew (peronospora sparsa) which is a pathogen that attacks the leaves, buds, flowers and fruits, causing the fruit to not develop or have a bad formation, this has caused great losses at a productive and economic level, which is why it has been necessary to look for control alternatives through both organic, chemical and alternative management plans (between chemical and organic) to help us eradicate the attack of this pathogen. In this study, the percentage of incidence of Peronospoa sparsa was evaluated in terms of mulching plans to determine the best treatment, the results were obtained by counting the number of fruits per plant, other variables to be measured were weight, Brix Degrees and yield Kg/ha. The treatments were 3 that received application of both chemical and organic products and one without application, these data were analyzed through a completely randomized design (DCA) and 5% tukey tests. The results reflected that the treatment (T2) which is a chemical management plan obtained a lower incidence of peronospra sparasa, as well as greater weight and better yield, but the T3 treatment (alternate management plan) obtained better results in brix degrees.
