Syngenta’s Callisto Xtra OK Anticipated

Callisto Xtra, the brand name for Syngenta Crop Protection‘s new postemergence corn herbicide, is expected to received EPA registration during the first quarter of 2010. The company says Callistro Xtra will be an excellent tank mix partner for glyphosate in glyphosate-tolerant corn.


The new herbicide combines two leading herbicides, Callisto and AAtrex, which perform synergistically to deliver long-lasting residual broadleaf weed control. In addition to corn, Callisto Xtra will also be registered for use in sugarcane.

“The weed control delivered from Callisto Xtra is better than expected based on the control from the individual components,” says Gordon Vail, herbicide technical brand manager, Syngenta Crop Protection. Vail says the two modes of action will provide enhanced control of broadleaf weeds that are becoming harder to manage with glyphosate alone.

“We will continue to provide Callisto to the market for use in corn greater than 12 inches in height, atrazine restricted areas, and for the wide range of other crops for which Callisto is registered,” says Carroll Moseley, herbicide brand manager, Syngenta Crop Protection. These include cranberry, blueberry, lingonberry, flax, pearl millet, asparagus, bluegrass grown for seed, perennial ryegrass grown for seed, tall fescue grown for seed, oats, rhubarb, grain sorghum, and sweet sorghum.
