In order to evaluate the effect of copper sulfate pentahydrate CuSO4 .5H2 O in the control of coffee rust Hemileia vastatrix Berk. et Br. the present research was carried out in the Toquián neighborhood of the San José Ixtepec ejido, municipality of Motozintla, Chiapas, Mexico. The experimental unit corresponded to 16 coffee trees and the useful plot with four central coffee trees, with five treatments: 0.5 l ha-1, 1.00 l ha-1, 1.50 l ha-1, 2.00 l ha-1 of copper sulfate pentahydrate and a control without application. A randomized block design with five treatments and four replicates was used, which resulted in 20 experimental units. The percentage of infection of coffee rust was evaluated before the application of copper sulfate pentahydrate, 15, 30, 45 and 60 days after application. Data in percent were transformed to sine arc √percent. The results show that the highest percentage of coffee rust infection was observed in the control treatment without application with an average of 22.12%, and the lowest infection in the highest dose treatment 2.00 l ha-1 with 7.33%. The results will be fundamental to put them into practice and thus develop strategies to control and combat coffee rust that will allow better production in the coffee plantations of the study area and the region.
