CGA 362622 is a new sulfonylurea herbicide being developed by Syngenta for post-emergence weed control in cotton. The proposed ISO name is Trifloxysulfuron Sodium, the current formulation is a 75 WDG, and the mode of action is ALS inhibition. CGA 362622 controls a wide spectrum of broadleaf weeds, a few grasses, and sedges. The use rates of CGA 362622 are extremely low, between 0.1 B 0.25 oz/A in cotton. CGA 362622 can be applied over the top of cotton at the early post application timing, (maximum of 0.1 oz/A, minimum of 3 leaf cotton), as well as post directed at the post, late post, and lay by application timings, (maximum of
0.25 oz/A). No more than 0.4 oz/A may be applied per season. CGA-362622 will be approved for use on conventional, RR, and BXN cotton.

CGA 362622 controls many of the most troublesome weeds in cotton. Weeds controlled include redroot pigweed (Amaranthus retroflexus), common cocklebur (Xanthium strumarium), coffee senna (Cassia occidentalis), sicklepod (Senna obtusifolia), hemp sesbania (Sesbania exaltata), pitted morningglory (Ipomoea lacunosa), and ivyleaf morningglory (Ipomoea hederacea). Suppression of yellow nutsedge (Cyperus esculentus), and purple nutsedge (Cyperus rotundus), is achieved with a single application and control of yellow nutsedge is achieved with a sequential application of CGA 362622. CGA 362622 controls both small and large weeds in cotton. Initial crop response in cotton can be 13% or less following an early post application of CGA 362622, (0.1 oz/A), and 6% or less with all directed application timings, but is gone within 14 days after application under normal growing conditions. Cotton yields have not been affected by applications of CGA 362622.
