Determinación del efecto de agrozoil sobre la incidencia de necrosis radical de fresa Fragaria x ananassa (Duch) variedad monterrey

Abstract

The strawberry crop Fragaria x ananassa (Duch) is considered of great economic importance at national and international level, so its production among farmers of this crop has become its main source of economic income, one of the main problems that occur in its production are the bad practices and agricultural actions that occur in an irrelevant way among farmers, which leads to generate economic losses and production of the farmer. Following this problem, certain organic prevention methods have been implemented which seek to maintain disease control to improve the quality of the product, so this study evaluates the effectiveness of the product called "Agrozoil" whose composition is associated with vegetable oils with an amount of ozone in the production of strawberry (Fragaria x ananassa) in which 3 different doses were applied (5; 7 and 10 cc / L). Subsequently, the number of diseased plants and the number of plants planted 20, 40 and 60 days after the application of Agrozoil were identified. The main results were: at 40 days, treatment 2 F1D2 (10 days, 7 cc/l) with 15.75% of disease incidence was the lowest of all, also in the leaf area the highest value of 36.44 grams was at 40 days in treatment 2 F1D2 (10 days, 7 cc/l), as for the length of the root system the highest was 12.45 cm, at 60 days with treatment 2 F1D2 (10 days, 7 cc/l), with reference to the fresh mass of the root the highest was 45. 82 grams on day 60 in treatment 1 F1D1 (10 days, 10cc/l), on the other hand, in the number of flowers the highest was 4 units in treatment 2 F1D2 (10 days, 7cc/l), so also the highest yield was 17133. 33 kilograms per hectare in treatment 2 F1D2 (10 days, 7cc/l), in addition, the size of the fruits was counted, which were separated in the category extra fruits > 51mm, of this result, the highest obtained was 1.73 averages, in treatment 4 F2D1 (15 days 10cc/l)). With reference to the first category, fruits between 31-50 mm, the highest mean was 2.89, located in treatment 2 F1D2 (10 days 7cc/l), and finally in the second category, fruits between 20-30 mm, the highest was 2.85 means, treatment 4 F2D1 (15 days, 10cc/l). With these results it is recommended to implement the use of Agrozoil in strawberry cultivation, because it is an organic product that provides nutrients to obtain a less polluting crop, besides helping to keep the root of this fruit vitalized and free of diseases (root necrosis)
