In 1976 expt. were conducted on var. trials, fertilization, insecticides, and herbicides in order to identify new technology that could be introduced into small- and intermediate-scale bean production in Honduras. Factors of a complete technological package were also discarded to identify the mos...

Beans are attacked by a large no. of plant pathogens and insect pests, many of which can reduce yields drastically. Farmers with small land holdings usually have limited resources but produce most of the beans in L.A. Control strategies feasible for these growers may be restricted to those strate...

El frijol es atacado por un gran no. de organismos fitopatogenos y plagas, muchas de las cuales disminuyen los rendimientos significativamente. Los agricultores que poseen pequenas parcelas tienen generalmente ingresos muy limitados pero producen casi todo el frijol en America Latina. Las estrate...
