Control químico del ácaro del café(Oligonychus sp.) en Cumbres de Huicicila, Compostela, Nayarit, México

The present study was realized in Cumbres de Huicicila municipality of Compostela, Nayarit with the purpose to find alternatives to control of Oligonychus sp. in coffee crop. The used treatments were: 1) sulfur 200 g·100 L-1 of water, 2) sulfur 400 g·100 L-1 of water, 3) abamectin 0.5 L· ha-1, 4) abamectin 1.0 L·ha-1, 5) fenpropratin 0.3 L·ha-1 6) fenpropratin 0.5 L · ha-1 and 7) control without applying. An experimental design was used in randomized complete blocks with four replications and seven treatments. The experimental unit consisted of five trees, which were selected from among and five leaves were collected, so taht the sampling unit was 15 leaves, five leaves per tree. Before applying treatments a sampling was performed to estimate the population density of the pest. A week after application of teatments, alive and dead mites were accounted the percentage of effectiveness of treatments. The resulting information was subjected to analysis of variance and comparison of means by Tukey´s test (α = 0.05), no statistical difference among means of mite per leaf was found with analysis of variance. The realized evaluation, one week after the application, showed statistical differences among treatments, so that the best of them was abamectin 1.0 L· ha-1 with average 0.37 individuals per tree, which represents 96.3% of control.
