Evaluación del jabón potásico y ozono como alternativa para control de paratrioza (Bactericera cockerelli sulc) en el cultivo de papa (Solanum tuberosum) variedad Superchola

Abstract

This research was developed with the purpose of evaluating the control of paratrioza (Bactericera cockerelli sulc) in the potato crop (Solanum tuberosum) superchola variety. With the application of Potassium soap and Ozone as an alternative solution for the prevention of this pest, responsible for the disease known as purple tip, which presents various symptoms such as leaf curling, yellowing of the plants and the presence of purple spots on new leaves, and the decrease in both flowering and therefore tuberization. This crop is has a great worldwide importance and especially in our country, due to the source of employment it generates, so the application of Ozone at 0.25 and 0.5%, and Potassium soap at 0.5 and 1% to control B .cockerelli in the potato crop, which helps to increase production and profitability, for this reason, a random block design was used with a 2x2+1 factorial arrangement with 4 repetitions and a chemical treatment as a control, in addition to using the ANOVA analysis of variance. and Tukey's LSD Test. Data collection was carried out at 30, 60, 90 and 120 days from the emergence of the potato. The variables evaluated were the number of eggs (h), nymphs (n) and adults (a), and production (kg). With the data obtained, 1% potassium soap was determined as the best product and dose, since its results in which the average number of eggs, nymphs and adults were 4.67, 4.18 and 49.25 respectively, reflected greater control over the presence of the paratrioza, and its average yield of 30.06 kg
