Four types of stalk-shredding operations, including both horizontal-rotary and vertical-flail shredders, were compared with a nonshredded check at Phoenix, Arizona, the winter of 1966-67 for effectiveness in reducing spring moth emergence of Pectinophora gossypielia (Saunders). The test was conducted in a field of Pima cotton which had been infested heavily with the pink bollworm during the 1966 growing season. Additionally, of the horizontal-rotary shredders was evaluated in an adjacent field of upland cotton. In the winter of 1967-68, a horizontal-rotary and 2 vertical-flail shredders were evaluated at Mesa, Arizona, on upland cotton, and a vertical-Hail was tested on Pima cotton at Safford, Arinzona. Hand-harvested stalks comprised the nonshredded checks in each experiment. Results indicated that the shredders had little, if any, direct influence on reducing pink bollworm populations in any of the experiments. All machines satisfactorily shredded the stalks which permitted better burial of plant debris.
