Armyworm Pheromone Trap Report – 2019
With large amounts of rain across the state during the month of May, farmers have struggled to plant hemp this season. There is also the threat of increased weed pressure and seedling diseases for anybody that manages to get seeds in the ground. From four years of hemp research at Purdue, we can attest that hemp does not like wet feet.
Many alfalfa fields in northeastern Indiana suffered serious winter injury. Statewide, alfalfa weevil damage was more common this year and control was difficult because of persistent spring rain. Timely forage seeding of perennial legumes and cool-season grasses this spring was not possible because of excessive rain. Continued rainfall has limited the ability to make hay on a timely fashion and forage quality will be compromised. A result of all of these concerns is that forage supplies in the Midwest USA will likely be reduced in 2019. Producers need to carefully consider all options to meet forage needs if winter injury and waterlogged soils reduced forage yield and quality.

Armyworm primarily feed on grasses. As seen in the past, and now being reported this spring, they will feed on no-tilled soybean into a cereal rye cover crop.
A few soybean fields were planted early, and they are not only emerged, but well into the V-growth stages. Producers are just now finding that these “islands” of legumes have become a trap-crop for bean leaf beetle activity early this season.
As we close the doors on May for the year, one of the biggest stories throughout the month was the precipitation. The entire state was above normal. Northwestern Indiana was 3.41” above normal and southeastern Indiana was 0.18” above normal for the month (Figure 1). Temperatures were near normal in the northern and above normal in the central and southern tiers of the state. Some stations in Central Indiana recorded rainfall on 24 out of 31 days.
