2020 Western Bean Cutworm Pheromone Trap Report
2020 Western Bean Cutworm Pheromone Trap Report
For the first time in what seems like months, the 8-to-14-day climate outlook is not showing significant confidence for above-normal temperatures in Indiana (Figure 1).
The vast majority of cornfields in the northwestern counties of Indiana have reached or have passed pollination.
Corn blotch leafminer, Agromyza parvicornis, is a leaf-feeding insect normally considered an “occasional or non-economic” pest.
Environmental conditions that exist when forages are ready to be harvested influences the amount of hours that it takes to get to a safe baling moisture.
White-tailed deer (Odocoileus virginianus) are among the common mammal pests of field corn in Indiana.
The “notched leaf edge” symptom in corn is a curious genetic leaf “disorder” that appears in certain hybrid families during periods of rapid development.
The past 30 days have been met with warmer than normal temperatures in the northern counties and drier than normal conditions throughout most of the state. This warm and dry environment is conducive to developing drought – particularly with the increased evapotranspiration rates. While climate outlooks are calling for increased confidence of above-normal precipitation throughout the rest of July, these events are likely to remain spotty with inconsistent coverage across the state.
Many plants have poisonous compounds that can cause all kinds of concerns, and even death, if consumed. The interactions that I have had with veterinarians, suggest that the yew is right at or near the top of plants that cause livestock death.
The field crop pathology research program is tracking the distribution of corn and soybean field diseases in Indiana. We are predominantly interested in the following samples (but always keeping an eye out for others):
Corn: tar spot, northern corn leaf blight, and southern corn rust
Soybean: frogeye leaf spot
