Efects of cow urine in the agroecological management of insects an witches' broom (Moniliophtora perniciosa Stahel Aime &Phillips Mora) in cacao crops (Theobroma cacao L.)
Witches' broom (Moniliophtora perniciosa Stahel Aime & Phillips-Mora) was first reported in th state of Bahia (Brazil), in 1989, in areas of cacao cultivation, where it immediately became the mos important disease of this culture, responsible for marked losses in production, mainly by weakenin the plants and causing leaf area reduction, leading even to the death of the adult plant. Afte several years of dropping cacao production in the southern region of Bahia, producers hav renovated their hopes for farming by adopting practices that favor increments in productivity, suc as stand renewal using productive, self-compatible genetic material that is more resistant to thi disease, thus enhancing the cultural management of cacao in agroforestry systems. In order t combat this disease, farmers have resorted to pesticides; however, their indiscriminate use has le to the contamination of workers and the environment, which is increasingly unbalanced an creating resistance to the fungus. Alternative methods to control this disease are already bein tested by the producers themselves, who have perceived improvements in their crops and in thei quality of life when using them, mainly since they are natural, cheap, and easily accessible, as i the case of cow urine pulverization. In this study, we evaluated the application of cow urine a different concentrations, with five treatments and four repetitions each, using a completel randomized design. The results showed that lactating cow urine at concentrations of 0.5%, 1.0% and 1.5% was as efficient as the pesticide used as a control in the experiment, simulatin conventional treatment. However, no significant differences in results were observed when usin the Tukey test at 5% probability.
