Black Cutworm and True Armyworm Moth Captures and Weed Pressure in SWNY
Joshua Putman, Field Crops and Forage Specialist
Southwest New York Dairy, Livestock and Field Crops Program

This week, Field Crops Specialist, Josh Putman, with the Southwest NY Dairy, Livestock, and Field Crops program scouted traps and fields throughout the region. In Avoca, NY, both moth species were present having 7 cutworm and 10 armyworm; not much larvae feeding was found. In Springville, NY 3 black cutworm and 3 armyworm were collected; we now have evidence of cutworm feeding on corn plants. According to Dr. Mike Stanyard of the NWNY Dairy, Livestock, and Field Crops team, it is important to be out scouting your fields now for pest damage and economic threshold that may require management. In addition, with the warm temperatures and increased day length, we are seeing an increase of weed pressure in our field crop production systems. Summer annual weeds compete for sunlight, nutrients and water. Don't let these pests rob your crop yields!
