Evaluación de dos herbicidas orgánicos para el control de malezas en el cultivo de caña de azúcar (Saccharum officinarum)

Abstract

This research was conducted in the Tarqui parish, Pastaza canton, Pastaza Province, Ecuador, during the months of October and November 2023. The objective was to evaluate two organic herbicides for the control of weeds in sugarcane cultivation (Saccharum officinarum). The variables evaluated were weed vigor and toxicity, and crop phytotoxicity. The treatments were T1 (Baner Kill at a dose of 20ml.L-1), T2 (Baner Kill at a dose of 25ml.L-1), T3 (10% vinegar at a dose of 20ml.L-1), T4 (10% vinegar at a dose of 20ml.L-1), and the control treatment was glyphosate at a dose of 10ml.L-1. The experiment was conducted in a completely randomized block design in a 2x2+1 factorial arrangement with 3 replicates. At 30 days after treatment application, the best treatment was H1D1 (Baner Kill at a dose of 20ml.L-1). Applying the Tukey test at 5% for weed vigor, it was located in range (a) with an average of 1; in weed toxicity, it is located in range (a) with an average of 99.00%; in phytotoxicity range (a) with an average of 3.33%, and in weed counting it resulted in 0 present, controlling broadleaf and narrowleaf species in an excellent way. In conclusion, it is recommended to use Baner Kill at a dose of 20ml.L-1 for the control of broadleaf and narrowleaf weeds in sugarcane cultivation.
