Evaluación de tres macerados vegetales con tres dosis cada uno, para el control del pulgón (brevicoryne brassicae) en el cultivo de col (brassica oleracea), en la parroquia Luis Cordero Cantón Azogues.

Abstract

This work was developed in the community of belonging to the parish Ayasamana Luis Cordero Azogues canton province of Cañar, which is 2622 m, with an average temperature of 16 ° C, an annual rainfall of 869.6 mm and humidity relative to 70%, these being suitable for the production of cabbage characteristics. In our country we can say that cabbage is a crop that has grown in recent years, with increased demand due to its nutritional properties therefore should be viewed and produce properly. The cabbage crop in times of drought has increased pest attack including the most important aphid (Brevicoryne brassicae), which has been inadequately controlled by insecticides that farmers have often generated pest resistance. Therefore it was proposed to investigate the use of natural macerated to avoid resistance and generate a clean crop for consumers especially in times where rains are scarce and where the pest is generated further damage. Hence arose as a general objective: To evaluate three macerated plant for aphid control in this crop. Meanwhile, the specific objectives were: to develop macerated plant for aphid control and macerated plant and determine the most effective dose. With regard to these objectives is the best treatment was observed with respect to plant height was the pepper mash with all doses for the number of aphids after inoculation between 8 and 72 days was observed that the pepper mash dose of 30 ml/l of water was more effective on the control of aphids, for diameter and weight of the cabbage, the pepper mash with the dose of 30 ml/l of water had a higher yield per plant (4.82 Kg) compared to the control (1.31 Kg) and finally to the variable days to harvest treatment with a dose of pepper 20 ml/l of water obtained fewer days (98), being the earliest in assay .
