Evaluación fitosanitaria de Diatraea saccharalis en caña de azúcar (Saccharum officinarum) variedad Poj negra, parroquia el Dorado, provincia de Orellana

Abstract

Sugarcane is one attacked severely crops by stem borer pest (Diatraea saccharalis), however, it is ignored by most farmers who do not carry out a proper phytosanitary control, causing a significant decrease in product performance therefore, by-products production. The research objective was to evaluate the phytosanitary control effect on pest Diatraea saccharalis in sugarcane, through different chemical products application, in order to minimize damage and improve yield. The methodology implemented had a quantitative approach, experimental design used was a randomized block design, using three treatments; T1 (Thiamethoxam + Lambdacyhalothrin), T2 (Deltamethrin), T3 (Profenofos) with a dose 1cc/l, plus as well as control under three replicates. Morphometric variables were measured like height and stem diameter, incidence, severity and crop yield were taken into account as yield variables. By means this methodology, it was determined T1 had greater efficiency in controlling compared pest to the other treatments, obtaining a stem with greater height and diameter, a better yield, and effective results by presenting a lower degree incidence; therefore, it is located on a scale 1 into result table. In this context, it concluded Thiamethoxam + Lambdacyhalothrin a dose 1cc/L is the most appropriate and effective product to pest control Diatraea saccharalis, because it obtained better results all measured variables, thus phytosanitary control importance is raised, since it contributes at development, sugarcane quality cropág.
