Eficiencia de una boquilla electrostática en el control terrestre de sigatoka negra mycosphaerella fijiensis m

The research on the efficiency of a nozzle in the electrostatic Black Sigatoka (Mycosphaerella fijiensis M.) control was carried out on the farm of 6.7 ha named Cuba, located in the Pajonal area Machala. The goals set out in the investigation were: 1. Establish the efficiency of the nozzle electrostatic control programs in the Black Sigatoka. and 2. Using the GIS as a tool for displaying the efficiency of the joint control. The experimental area was 3.8 ha area where plots were set up 10 plants each, with four replicates in a randomized complete block. The repetitions were four, two products were used organic (Quitosano-based nutritional formula and Potassium) Fungicide a conventional family of tebuconazole. Witness and treatment. It was conducted eight consecutive applications at intervals of 21 days. The atomizers were ground using a jet electrostatic incorporated in a pump motor. The variables were evaluated: State of evolutionary Black Sigatoka, Index of Severity of illness at the time of flowering, Drift, and the mapping of the evolution of the disease using GIS and GPS. The results show significant differences in the evolutionary state variables, young leaf with striates, rate and severity of drift, when all these have been low in the Electrostatic applications, but not the same variables, had no significance when applications were made without the system. We conclude that, under the conditions of this test, the electrostatic effect caused an improvement in the impregnation of the products applied in stages to increase the efficiency of control and geographic information systems helped visualize the spatial distribution of the disease.
