Abstract
During the summers of 1969-71, an average of 11,152 acres of cotton was examined weekly at an average season al cost of $1.65 per acre. Resulting information Contributed to grower decisions to eliminate pesticide applications season long from 84, 82, and 71%, respectively, of the acreage during these years and to make 1.6, 1.7, and 3.8 applications, respectively, per treated acre, largely for control of the pink bollworm, Pectinophora gossypiella (Saunders). Costs were much lower than under a grower-sponsored program in 1968, when 13,263 acres each automatically received 6 pesticide applications.
