Astute observers have recently reported mysterious egg masses on the outside of their homes, including siding, gutters, soffits, facia, and porch ceiling fan blades!
Soybean fields throughout the state are rapidly undergoing their annual color changes, deep green to golden yellow.
The sugarcane aphid (Melanaphis sacchari), a relatively new pest of grain sorghum, forage sorghums, sudangrass, sorghum-sudangrass hybrids and Johnson grass, first detected in Indiana in 2016, is making its presence known primarily in southcentral and southwestern counties.
Reports of denuded forage crops, especially alfalfa, from large numbers of fall armyworm have been shared from throughout Kentucky and southern counties of Indiana and Illinois.
In recent weeks, fall armyworm infestations have been decimating some soybean and forage crops in Kentucky.
Although some other states in the corn belt, and to the north in Ontario, Canada are seeing high moth flights (and we thought Indiana would follow suit), as it turns out, Indiana is a “have-not” state for WBC this year.
Corn and soybean growers are very familiar with neonicotinoid seed treatments, and some of the debates that surround their use – including examining their yield benefits and the potential for off-target negative effects.
It’s western bean cutworm season – as discussed in last week’s Pest&Crop, moth trap counts are peaking, primarily in Indiana’s northern counties.
The western bean cutworm (WBC) trapping season continues, and after a slow start, moth flights have rapidly increased in many northern Indiana county traps this past week.
