Novas técnicas no controle de doencas e pragas do cacaueiro
The margin of profit in cocoa production is experiencing a considerable reduction due to increase in cost of inputs. One of the increases is attributed to chemical control of diseases insect pests. In addition pesticides routinely used need to be reexamined for detrimental effects on the ecosystem. The application of pesticides may remain the main system of control of diseases, caused by Phytophthora spp., Corticium and Crinipellis: pest such as Monalonion, Selenothrips, Xyleborus, and other responsible for defoliation and storage problems. In this line of research considerable advances have been made, aimed at less wasteful and more timely applications and also a research for alternate products. However, for economic reasons, urgent consideration need to be given to systems involving integrated control. Various studies to date show that integrated control involving genetic host selection, cultural practices, physical aspects (agroecological) and biological control are showing good returns in production with minimum collateral effects.
