Small coffee growers consider the existing recommendations for managing the coffee-berry borer to costly and revert to home remedies. Within these producís figures the mixture of creolin, molasses and lye, with unknown effects on the plant nutrition, the quality of the grinded coffee and the possible phytotoxicity. To determine these aspects, different proportions.in several application frequencies of the mixture were evaluated in a plot, plantes with the coffee vac Colombia. The methods employed were foliar analysis to know the ¡nfluence of the mixture on the nutritional State of the coffee plant; weekly evaluations of the phytotoxicity according to a visual scale of 0 to 3; benefit and processing of the harvest and quality evaluation by means of a survey. The results showed no marked influence of the components of the mixture on the nutritional State of the plant. In general an increased concentraron of calcium and magnesium, and a decrease in the boron content was detected. Although the content was considered adecúate, the treatments decreased the potassium concentration compared with the check, due possible to the effect of Ca and Mg. Nitrogen content was not affected; however the relationship of this nutrient with Ca, K and Mg was found disbalanced, compared to normal, aspect which could influence the yield. During the 17 weeks, the field experiment was carried out, no sympthoms of phytotoxicity were observed. The coffee plant foliage preserved its normal coloration, neither were flowers affected by the applications. The survey indicated that the applications of the mixture neither affected the grain quality ñor that of the beverage, being the samples evaluated between desirable and reduced quality. In no moment the tasters detected flavor or taste of phenol, active ingredient of creolin.
