This project was initiated in 1991, following concern expressed by local cotton growers about suspected high insecticide resistance at St George. The performance of synthetic pyrethroids had been inadequate for a number of years, and was getting worse over time. The Balonne Resistance Committee, now the Balonne Cotton Advisory Committee (BCAC), was formed by the St George Cottongrowers Association. This committee, comprising growers and agronomists, requested assistance from the Department of Primary Industries (DPI), resulting in the establishment of the St George Heliothis Monitoring Program with CRDC funding
