Estudios iniciales sobre la produccion de habichuela en Sumapaz, Colombia, indicaron uso excesivo de plaguicidas en la region. En 1989 se inicio una investigacion mas a fondo sobre la utilizacion de productos quimicos para controlar insectos y enfermedades y sobre las implicaciones economicas y agroecologicas de este uso. La confiabilidad en los plaguicidas se relaciono en gran parte con la susceptibilidad a enfermedades de la var. mas popular cultivada, Lago Azul. De los agricultores encuestados, 90 por ciento asperjaba sus cultivos una vez por semana con una mezcla de 1-2 plaguicidas, 2-3 fungicidas y un fertilizante foliar. Al parecer, la aplicacion indiscriminada de insecticidas tiene poco o ningun efecto en el rendimiento, aunque si un efecto destructor en los enemigos naturales del minador de las hojas. Sin embargo, la habichuela evaluada hasta el momento por residuos quimicos de la region no ha mostrado niveles considerables de contaminacion. (RA- CIAT)
Initial studies on snap bean production in Sumapaz, Colombia, indicated excessive use of pesticides in the region. A more in- depth investigation of how chemicals are used to control insects and diseases, and the economic and agroecological implications was thus initiated in 1989. It was found that reliance on pesticides was largely related to the disease susceptibility of the most popular variety grown, Lago Azul. Of the farmers surveyed, 90 percent sprayed their crops once a week with a mixture of 1-2 pesticides, 2-3 fungicides and a foliar fertilizer. Indiscriminate application of insecticides appears to have little, if any, effect on yields, but a destructive effect on natural enemies of leafminer. So far, though, snap beans tested for chemical residues from the region have shown no appreciable levels of contamination. (AS)
