Performance of Blizzard™ Defoliation Treatments Across the Cotton Belt A. Dalrymple, K. Griffith and R. Hinkle Chemtura USA Corporation
Blizzard™ Characteristics Common name: fluthiacet-methyl Mode of Action: inhibition of Protoporphyrinogen oxidase (PPO or PROTOX) Formulation: EC – 0.91 lb ai/gal Use rates tested in cotton: 0.4 – 0.6 fl oz/A Seasonal use total not to exceed 1.25 fl oz/A Requires a crop oil concentrate (COC) adjuvant to maximize performance - Not unlike other PPO defoliants
Field Trial Objectives Evaluate Blizzard™ for cotton defoliation performance compared to other PPO defoliant products in picker and stripper types of cotton across the Cotton Belt. Obtain performance data for Blizzard + ethephon products commonly used such as Finish® 6 Pro, FirstPick™ and Prep®. Measure performance of Blizzard in sequential applications with paraquat products Firestorm™ and Gramoxone® Inteon. Confirm Blizzard use patterns and performance with thidiazuron products such as Dropp® 50W and Dropp® 4SC. Evaluate performance of aerial applications.

Blizzard Cotton Defoliation Performance in South Texas - 2006
Summary Blizzard 0.91EC provided effective cotton defoliation across a number of locations and environments and was comparable to Aim, ET and Resource at rates tested. Ethephon products CottonQuik, FirstPick, Finish Pro and Prep enhanced defoliation performance when tank mixed with Blizzard. Blizzard treatments were equal to “standards” in Mid-South university trials. Dropp followed by Blizzard and Dropp + Blizzard followed by Blizzard were effective defoliation and regrowth suppressing treatments in south Texas. Blizzard + ethephon was more effective than Resource + ethephon for regrowth suppression in two south Texas trials. Single applications of Blizzard + ethephon were equal to other PPO defoliants in leaf removal while showing less leaf desiccation than Aim or ET in Georgia consultant demonstrations. Blizzard + ethephon followed by Blizzard and Firestorm (paraquat) were very effective treatments applied by airplane to irrigated cotton in West Texas.
