ABSTRACT

Suprend™ is a new post-directed herbicide pre-mix for use in Cotton developed by Syngenta Crop Protection, and its application for registration is currently pending with US EPA. Suprend™ is a pre mix of trifloxysulfuron sodium (the active ingredient in Envoke™) and prometryn (the active ingredient in Caparol™), formulated as an 80 WG in a 1:112 ratio. Suprend™ contains two herbicide modes of action that aid weed control as well as provides sound glyphosate resistance management. Suprend™ also provides excellent residual weed control in cotton. Suprend™ is compatible with conventional, Roundup Ready^® and BXN^® cotton production systems.

Economically important weeds controlled by Suprend™ in cotton include but are not limited to: coffee senna (Cassia occidentalis), hemp sesbania (Sesbania exaltata), sicklepod (Senna obtusifolia), common cocklebur (Xanthium strumarium), pitted morningglory (Ipomoea lacunosa), ivyleaf morningglory (Ipomoea hederacea), entireleaf morningglory (Ipomoea hederacea var. integriuscula), redroot pigweed (Amaranthus retroflexus), smooth pigweed (Amaranthus hybridus), and suppression of seedling johnsongrass (Sorghum halepense), yellow nutsedge (Cyperus esculentus), and purple nutsedge (Cyperus rotundus).

Suprend™ can be used in all picker cotton varieties across a large section of the southern cotton growing areas, including the Southeast, Mid-South as well as portions of Texas. Applications should be post directed beginning in cotton as small as 8 inches in height up through the lay-by timing. Use rates will be 1 to 1.5 pounds of formulated product per acre. Do not apply more than 2.7 pounds of formulated product per year nor do not apply 60 days before harvest. Suprend™ is expected to be available for the 2004 cotton use season.

Tank mix options include several commonly used herbicides in cotton such as MSMA, Touchdown^®, Dual Magnum^®, Aim™, diuron, linuron, Cobra^®, Caparol^®, and Buctril®. Do not tank mix Suprend™ with malathion, profenofos (Curacron^®) or emamectin-benzoate containing insecticides (Denim^®), acephate, Bidrin®, Capture^®, Karate^® or unacceptable cotton injury can occur.

Rotation restrictions include: 3 months: wheat, transplanted tomato, 7 months : cotton, corn, sorghum, peanut, rice, soybean, transplanted tobacco, 12 months bell pepper, Irish potato, radish, parsley, 18 months: all other crops.
