Another encouragement to scout high-risk corn and soybean fields as they emerge. Black cutworm larvae, some near pupation, were reported cutting soybean seedlings in Southwest Indiana. The river bottom fields, lush with weeds earlier this spring, had lost 4 to 8,000 plants/acre from the damage. Because of soybeans ability to compensate for lost plants, and the size of the cutworm larvae, no treatment will be necessary in these fields. Fortunately, the damage was scattered throughout, rather than concentrated in areas of the fields. If replanting, or filling-in, is being considered, the following publication may be of help, click HERE. In West Central Indiana, black cutworm damage was being reported in one-leaf sweet corn planted into cover crop residues. Most plants had some leaf feeding, and cutting[Read More…]

Moth trappers have been busy counting…look at the following “Black Cutworm Pheromone Trap Report”
Could this be a cutworm year? Black cutworm moth catches in many of our cooperator’s pheromone traps continue to be quite impressive (see “Black Cutworm Adult Pheromone Trap Report”).
When looking over the Black Cutworm Pheromone Trap Captures, you will notice that there have been some very busy traps!
Black cutworm trap cooperators have detected that moths are beginning their traverse to Indiana this past week.
Many black cutworm trappers have captured large numbers of moths, see “Black Cutworm Pheromone Trap Report.” In trying to find levity during the Covid-19 pandemic, there have been various quips during their reports about this pest’s lack of adherence to our social distancing guidelines!
