Different types of herbicides in inducing the hormetic effect on soybean culture

Abstract

The objective of this study was to evaluate the effect of 2,4-D and chlorimuron-ethylunderdosage on the soybean hormesis effect. The study was conducted in the facilities of the University Center of Vale do Araguaia (UNIVAR), in Barra do Garças, MatoGrosso. Was used or the randomized block design (DBC) with five replications for each treatment, where an experiment was performed for 2,4-D and another forchlorimuron ethyl. The treatments used were: 2,4-D (0, 5, 10, 15 and 20g ea ha-1) and Ethyl Chlorimuron (0.4, 0.8, 1.2 and 1.6 g eaha-1). The use of the lowest chlorimuron dose and the highest 2,4-D tested showed significant results for plant height, stem diameter, biomass accumulation and dry matter.
