Abstract
Changes in net returns from modifications in insecticide use are evaluated by estimation of three component models: a yield function, a cotton-quality relationship and an alternative pesticide use equation. Data from 41–99 production regions and 3 crop years are used to evaluate a shift from conventional insecticides to ground-applied aldicarb for late-season insect control. Analysis of multiple effects of insecticides reveals that net returns from aldicarb use in the short term are about 220%. This change in pesticide use has improved yields and increased cotton quality.
