Importância dos adjuvantes na eficiência de controle de plantas daninhas

Abstract

The need to increase the effectiveness of herbicides in weed control motivated the development of this work, which aimed to identify the effect of different adjuvants in weed control. The same was conducted in an experimental field for soybean production at the State University of Goiás, Ipameri unit. The weeds at the initial stage were subjected to desiccation with the use of a mixture of herbicides Glyphosate Zapp QI 620 and Verdict Max and five different combinations of adjuvants corresponding to the treatments (Iharol gold, Dessek, Alvo, Alvo + Agrofix, Dessek + Agrofix). The variables evaluated were performed at 24 h, 72 h and 120 h after application, where they presented significant results in relation to the evaluated parameters of temperature of the plot, control efficiency of wide, narrow leaves and the total of weeds. All adjuvants, with the exception of Iharol, promoted greater efficacy in the control of weeds (narrow and wide leaves), in all periods evaluated (24 and 72 and 120h).
