The aim of the study was to evaluate the effectiveness of a combination of personal protective equipments (PPE) for the tractor operator applying herbicides on soybean and peanut crops with a tractor mounted boom sprayer and the safetyness of these work conditions. The application of the herbicides were in pre-planting soil-incorporated (ppi), pre-emergence (pre) and post-emergence (post) treatment, with volumes of 200 L ha-1, except in the post application for soybeans where it was 150 L ha-1. It was shown that exposure with PPE was 102.77 mL of spray per day in ppi, 39.62 in pre and 47.14 in post applications. The effectiveness of PPE in controlling dermal exposure was 76.5% in ppi, 50.9% in pre and 75.3% in post applications. With soybeans, were safe for the tractor operator, with or without PPE, the applications of the herbicides pendimethalin, imazaquin and flumetsulam in ppi; pendimethalin, acetochlor, clomazone, flumioxazin, imazaquin, metribuzin, sulfentrazone, dimethenamid and flumetsulam in pre; and bentazone, glyphosate, imazethapyr, quizalofop-ethyl, chlorimuron ethyl and oxasulfuron in post. In peanut crops, were safe the application of pendimethalin ppi, with and without PPE. In pre, the application of alachlor was classified as unsafe with or without the use of PPE.
