"the best opportunities for achieving quick gains in productivity may be by making small, simple improvements in farmers' current practices. this approach must be based on research firmly rooted in the environment and land-use system of the target group of armers and must reflect the farmers' own criteria for success. in this context, on-farm research is indespensable in achieving agroforestry's long-term research objectives."

    "biological control is particularly appropriate for pest problems where: a certain amount of damage is tolerable; the initial or recureent cost of other control methods is too high in comparison with the value of the crop; or existing control measures are unsatisfactory, or their deleterious side effects are unacceptable."

    "crop protection specialists are increasingly being asked to develop pest control methods that are more compatible with the goals of sustainable, productive, stable and equitable agriculture. to meet these aims, research must seek to integrate a range of complemetary pest control methods in a mutually enhancing fashion..."
