From Luis Espino UCCE Rice Farming Systems Advisor
The number of true armyworm moths has shot up quite a bit in several locations. True armyworm has been the problem species in the past. Western yellowstriped armyworm moths have been variable, increasing in some locations, decreasing in others, but in general, the numbers are much lower than at the beginning of the season.
The Intrepid® 2F Insecticide (EPA Reg. No. 62719-442) section 18 has been approved for use in Butte, Colusa, Glenn, Merced, Sacramento, San Joaquin, Sutter, Yolo, Yuba Counties.
UCCE Rice Farm Advisor Luis Espino reports in this week’s update that true armyworm numbers are on the rise.
