Evaluación de tres productos para el control de Oídio (Oídium sp.) en el cultivo de duraznero (Prunus persica) en el Cantón Cevallos

Abstract

The objective of this study was to evaluate three products for the control of powdery mildew (Oídium sp.) in the peach crop (Prunus persica) in Cantón Cevallos. In an established crop of badger variety and 5 years old. This project was carried out specifically in Caserío Santo Domingo in the property of Mr. Olguer León. We analyzed which is the best product and the best frequency of applicationfor powdery mildew control, the variables studied are: percentage of incidence, fruit size,fruit weight, measurement of chlorophyll and nitrogen. The treatment that gives us the lowest incidence and the one that gives us the highest weight and size is T3 and the one that contains the best chlorophyll and nitrogen is T1. All these data were analyzed in a significant Tukey test at 5% which results show that the lowest percentage of incidence is 13.06% and the highest weight 102.67 g, the largest equatorial size 6.27cm, the largestpolar size 7.03cm, these results are obtained with treatment 3 (Libertaje), in chlorophyll we have 20, 16SPAD, in nitrogen 6.58mg/g, these results were obtained with treatment 1(Vitanica ZR) to obtain a lower percentage of incidence and give a better crop yield withhigher production and quality fruit, the product that helps us with these results is the Libertaje in the frequency of application every 12 days
