EFEITO DE DIFERENTES PRODUTOS QUÍMICOSS NO CONTROLE DA BROCA DO CAFEEIRO (Hypothenemus hampei)

Abstract

The research was conducted at Fazenda Estreito, located in the municipality of Guapé, Southern region of the state of Minas Gerais. For conducting the experiment, adult plants (approximately 1.90 meters tall) of the Catuaí cultivar are used Yellow 62. The experimental design used was randomized blocks (DBC), and the treatments consisted of four active ingredients, being Chlorantraniliprole, Abamectin, Azadiractin, Beauveria bassiana IBCB 66,

Ciantraniliprole, used to control the coffee borer, and the Witness used if only water. Percentages of grains attacked by the borer were investigated

7 days after the first and 15 days after the second application, and the control efficiency. The lowest number of grains drilled was with the treatment with Beauveria bassiana IBCB 66, in which the best result was obtained in the experiment, and a greater number of live insects was obtained, when only water was used. With the use of the same product (Beauveria bassiana IBCB 66) presented 9.9% efficiency in pest control and a biological product can be effective in controlling of pests. It is concluded that Ballvéria® product (Beauveria bassiana IBCB 66) can be effective in controlling the coffee borer, providing a decrease in the quantity of brocaded beans, reducing losses for coffee producers and assisting the work of the Agronomist in the fight against this pest.
