M. O. Way said new technology is available to help manage some of rice producers’ most damaging insect pests.

“CruiserMaxx and Dermacor X-100 have Section 3 labels for rice,” Way said. “Nipsit INSIDE likely will have a Section 3 label on rice within two years. An EUP for Nipsit INSIDE was approved in Texas for 2011. All three new technologies are being evaluated in Texas for control of an array of pests including the rice water weevil, a key pest of rice in Texas.”

Way said a 2010 seeding rate study with Dermacor X-100 applied to Cocodrie seed at 1.75 fluid ounces per hundredweight with seeding rates of 60, 90 and 120 pounds per acre resulted in excellent rice water weevil control. “Yield increases were 888, 993, and 1,100 pounds per acre, respectively,” Way said.

He said Cruiser 5FS, “the insecticidal component of CruiserMaxx,” applied to Cocodrie seed at 3.3 fluid ounces per hundredweight, also provided excellent control of rice water weevil when seed was planted at 90 pounds per acre in the same study.

He said increased yield from the Cruiser 5FS treatment was 1,183 pounds per acre. A separate Nipsit INSIDE study, applied as a seed treatment to Cocodrie at 3.3 fluid ounces per hundredweight, “provided excellent control of rice water weevil with 1,048 pounds per acre yield advantage compared to untreated seed.”

Way said a long-horned grasshopper control study with Tenchu at 8 ounces per acre resulted in 95 percent mortality. “We’re working on a Section 18 for Tenchu,” he said.
