Evaluation of Mepiquat Chloride Management in Irrigated Cotton

A field experiment was established in a commercial cotton field under the management of Algodonera de Baja California in Ejido Tula in the Mexicali Valley, Baja California, Mexico in 2006. The study was conducted with two main objectives: 1) Evaluate University of Arizona (UA) guidelines for mepiquat chloride (MC) management in irrigated cotton in the Mexicali Valley of Baja California, Mexico; and 2) evaluate a series of MC treatments in terms of crop vigor control, fruit retention, crop maturity, lint yield, and fiber quality.  Results will be presented in relation to previous research results and an evaluation of over 20 years of field experimentation in this region.
