Second, knowledge of the user groups' resource base and the institutional framework within which the group operates—producers or those who advise them —prevents the conduct of research that might otherwise lead to the development of unfeasible or inappropriate technology. Third, the use of economic criteria to develop and refine pest control strategies helps to ensure that the end-product of the research is not only feasible and ecologically appropriate in this context but also preferable to the users' current approaches.
