The participatory research cum extension methodology was used in generating and validating IPM component technologies for rice and vegetable crops under farmer's field condition. Results indicate that farmer's practice in controlling pests are traditionally pesticide dependent and the research methodology offered the opportunity to compare their traditional practice with that of the IPM approach. In addition, the two-year data showed that IPM approach can reduce pesticide use by as much as 50% without adversely affecting yield. This information appealed to sensitivities of cooperators' wives whose primary concern is to reduce costs of farm inputs so they can stretch the family income to the actual needs of the household.
Finally, it was noted that the cooperators' wives have varying levels of participation in farming activities. Wives of rice farmers normally do not have direct on-farm participation but have a significant role in the choice and purchase of pesticides. On the other hand, wives of vegetable cooperators have more direct roles in on-farm activities in that they take care of the crops after planting until harvest. Farm women decide on matters of pesticide use, hired labor and marketing of crops.
