This research aimed to determine the contamination of spraying equipment on operators during applications to control coffee berry borer. Productive coffee plots were selected at La Catalina Experimental Station in the municipality of Pereira (Risaralda). The evaluated equipment were: hydraulic back sprayer with lever, retained pre-compression 40-100-10, retained pre-compression with vertical sprayers and semi-stationary hydraulic motorized back sprayer. The study was carried out in two moments during the day with five operators at the time. A randomized complete block design with 10 repetitions per equipment was used. Thirty-nine kromekote paper cards were placed on each operator in different parts of a protective suit: cap, operator glasses, mask, overall, gloves and boots. As a colorant, 1% technical methylene blue was used. The cards were digitized and the percentage of the card area covered by the spray and the number of drops per card were determined through a Scilab 5.4.0 image analysis program in Linux. The results showed an exposure to pesticides in all the elements of the protective suit. However, the mask and the operator glasses had the least contamination; while the gloves and the cap had the highest exposure. The hydraulic motorized back sprayer equipment deposits the least amount of product on the operator during spraying. In contrast, the retained pre-compression with vertical sprayers equipment produces the greatest contamination on the operator.
