Evaluación de recomendaciones técnicas de almacenes agrícolas para el control de paratrioza (Bactericera cockerelli sulc.) en papa en Chambo, Colta y Guamote, provincia de Chimborazo

Abstract

This investigation aimed to evaluate the technical recommendations of the agricultural warehouses for the control of paratrioza in potato in the cantons Chambo, Colta and Guamote, in Chimborazo. Descriptive and correlational methodology was implemented in an experimental way since the technicians of the agricultural warehouses were interviewed by using images of the insect and the symptoms of purple top in order to know their recommendations for control. The results showed that only 8.16% of the technicians surveyed were able to provide an adequate recommendation, based on exclusive insecticides in the crop with adequate dosages, correct application frequencies and effective rotations by changing the mode of action to avoid resistance. The recommended products were Buffago (1B - Fipronil 70 g.L-1 + Profenofos 500 g.L-1), Curacron (1B - Profenofos 500 g.L-1), Engeo (3A and 4A - Lambda-cyhalothrin 106 g.L-1 + Thiamethoxam 141 g.L-1) and Solvigo (6 - Abamectin 36 g.L-1 + Thiamethoxam 72 g.L-1). It is concluded that 100% of the technicians were able to recognize the pest, but not all were able to give an adequate recommendation, determining that 91.84% of all the technical recommendations of the farm houses were wrong. This confirms that there is an inadequate use of insecticides for the control of paratrioza in the cantons Chambo, Colta and Guamote.
