The barangay (village) integrated pest management (IPM) project was conducted to determine the costs, benefits, institutional requirements, farmer training needs and constraints to IPM implementation in irrigated rice ecosystem. The study compared three treatments corresponding to three pest control regimes set-up in separate villages. Treatment 1, T1, is no pesticide spraying for the whole duration of the crop in contiguous 60-hectare rice area farmed by 33 households in La Torre, Talavera, Nueva Ecija [Philippines]. Treatment 2, T2, is composed of 28 farms cultivated by IPM trained households in Matingkis, Munoz, Nueva Ecija. Treatment 3, T3, or farmers' practice treatment, is comprised of 30 randomly chosen farms cultivated by households with no training in IPM in Sto. Rosario, Sto. Domingo, Nueva Ecija. Two-year data showed consistently that for the dry season yield, T1T2T3 and for the wet season yield, T2T3 T1. Compared with the benchmark data, T2 yield was higher after the IPM training. Income from rice was also consistently highest in T2. Insecticide use remained the same for T3 over the years, almost zero in T1, and dramatically decreased in T2 during the period of IPM training. After the training, insecticide used in both T1 and T2 were comparable. Herbicide and molluscicide use in T2 was significantly reduced. Half of the T2 farmers succeeded in their experiment to substitute water management for herbicide
