ABSTRACT: There is a need for an increase nin efficiency and a reduction in the risk of environmental contamination in controlling weeds; this can be obtained with the development of the new techniques for the application of herbicides. The objective was to verify the efficiency of different herbicide application techniques on soybean crops (Glycine max (L.) Merrill). The experiment was conducted in a commercial area in the municipality of Sinop, Mato Grosso state. The design was a randomized block, with four replications and six treatments, namely: herbicide application with a manual backpack sprayer; application with an acrylic wool roll with 9 mm long hairs; sheep’s wool roller with 9 mm long hairs; high density polyester foam roller; weeding with a hoe and free growth (no control). The used cultivar was TMG 132. The herbicide spray used in the treatments was: glyphosate 960 g ha-1, 80 g ha-1 haloxyfop-p-methyl 600 mL ha-1 and oil, diluted in water and applied 14 and 27 days after emergence (DAE). The weed population, vegetative growth, chlorophyll content and soybean yield were evaluated. The use of the sprayer and the application with the sheep’s wool roller showed greater efficiency in weed control, but the mixture of herbicides resulted in culture phytotoxicity when applied via foliar spraying.
