Temperatures warmed into the 80s by the end of Memorial Day weekend, but low dew point temperatures made the heat bearable.

Armyworm moth captures have varied throughout the state for the last eight weeks (see “Armyworm Pheromone Trap Report”).
Cool mornings and warm afternoons have made conditions pleasant across the state.
The weather has been absolutely beautiful over the past few days. Temperatures have finally rebounded, vegetation is green again, and agricultural crops are beginning to emerge from the freshly planted fields. Despite the warming temperatures, we still have not dug ourselves out of the below-normal start to May. Through the first ten days of the month, Indiana averaged 0.7◦F below normal (Figure 1). The largest departures occurred in climate divisions 6 and 9, which were 1.6◦F and 1.9◦F below normal, respectively. Angola, located in Steuben County, was the coldest location with an average temperature of 50.9◦F (4.0◦F below normal). Evansville was the warmest with an average temperature of 63.4◦F, which was 2.0◦F below normal. Accumulated Modified Growing Degree Days (April 1 – May 10) continued to run within 60 MGDDs of normal throughout the state (Figure 2). Statewide, MGDDs have accumulated between 160 and 420 units since April 1. Four-inch[Read More…]
Every spring, voluteers throughout the state put forth considerable effort in trapping for the arrival and intensity of black cutworm moths. We are indebted to these faithful bug counters, hoping you also appreciate their efforts as reported in the “Black Cutworm Adult Pheromone Trap Report.” If you recognize a name or two on this list of volunteers, by county, please thank them for their efforts! Heck…buy them a cup of coffee! Not since 2012 have we seen such an early flush of black cutworm moths! As described in a Pest&Crop #3 article, an intense storm causing lives and destruction on April 1, also brought massive numbers of moths from the Southwestern States. In addition, we’ve not had widespread freezes since then. Because of that, we set that date as biofix, and began accumulating heat units for cutworm development, that also tracks very closely to corn development. This is all explained[Read More…]
Once again, we urge you to view the “Black Cutworm Pheromone Trap Report.” For the fifth consecutive week, our volunteer trappers have been busy counting captured moths, e.g., lots of intensive captures.
It is May, the sun is shining, of course the wind is blowing, and the weather forecast is calling for warmer temperatures.
Early planted corn always involves the risk of cold weather in the weeks after planting.
