Interpretive Summary: We developed the short-season cotton management system that was adopted by the Imperial Valley, California for pink bollworm control in 1989. Trap catches of male pink bollworm (PBW) moths were reduced from 10.81 to 0.17 male moth/trap/day from 1989 to 1994. During the same period, lint yield increased from 6.2 to 6.9 bales/ha and grade 31 or above lint increased from 54 to 99. The short-season cotton management system may be useful as a component of resistance management programs to delay or reduce development of PBW resistance to transgenic (Bt) cotton.
