Insect research at the LSU AgCenter’s Rice Research Station is concentrating on three pests: stinkbugs, rice water weevils and Mexican rice borers.
LSU AgCenter entomologist Dr. Mike Stout said farmers probably will have two new products to fight weevils soon. A new seed treatment, NipsIt, could be available for weevil control next year from Valent. In addition, a new Valent product, Belay, is expected to be released for foliar application. Both are in the neonicotinoids group of chemicals.
Stout also said he is working with LSU AgCenter rice breeder Dr. Xueyan Sha to develop varieties resistant to weevils, but he said any results from those efforts are years away.
Research regarding stinkbugs is focusing on the appropriate threshold level for control efforts, and Stout said the second year of research continues to suggest the currently recommended threshold should be increased.
Farmers also got help with the stinkbug problem this year with the Section 18 release of Tenchu, and the chemical may also be available next year.
Stout said stem borer research is continuing – with work on resistant varieties and insecticides.
"The LSU AgCenter will continue to cooperate with the Louisiana Department of Agriculture and Forestry to monitor the spread of the Mexican rice borer into Louisiana using traps baited with pheromones," he said, adding, however, that it is inevitable the pest will continue moving eastward into the state.
"The real question is: How severe of a pest will it be?"
