Interpretive Summary:

Technical Abstract: Acala 1517-99W (Widestrike) is a trademark of Dow AgroSciences LLC for its proprietary Bt cotton trait expressing Cry1F and Cry1Ac insecticidal proteins from Bacillus thuringiensis. This Widestrike trait is intended to offer season long protection against a broad spectrum of insect pests including bollworms and pink bollworms. Acala 1517-99W was derived from a cross of Acala 1517-99/Phy72W and then backcrossed three times using Acala 1517-99 as the recurrent parent. Acala 1517-99W has been extensively tested in the Mesilla Valley and the Pecos Valley of New Mexico in 2003, 2004 and 2005. This new cultivar showed consistently higher yield than the Acala 1517-99 check. Since its release in the United States in 2005, Acala 1517-99W has been grown on from 1,500 acres to 8,417 acres during the 2005 to 2007 cotton production years and has increased cotton production by an estimated 70-140 pounds per acre where grown. The development of Acala 1517-99W was supported in part by funding from USDA-ARS and Cotton Incorporated. An intellectual property right with ownership of Acala 1517-99W was granted to Dow AgroSciences by the New Mexico Agricultural Experiment Station for commercialization in 2005.
