After several weeks of above-normal precipitation across much of Indiana, we are now entering a relative dry period.  The national Climate Prediction Center is indicating enhanced chances for below-normal precipitation amounts over the next several weeks.  Temperatures are also expected to be above normal over this period which will cause increased rates of evapotranspiration.  This may induce the onset and establishment of a flash drought – defined as a rapid intensification of drought conditions and impacts sustained for a relatively short amount of time (e.g., less than a year).  The key is to start planning and preparing for this now, even if a flash drought does not end up developing, so that one is being proactive rather than reactive to drought impacts. Modified growing degree days range from about 1500 units (northern Indiana) to 200 units (southern Indiana) (Figure 1).  With temperatures being relatively mild lately, this has kept accumulated[Read More…]

It is important to continue to scout for diseases in both corn and soybeans. Recent rains have created favorable environmental conditions for the development of foliar diseases in both crops. In our scouting rounds this week we continue to find gray leaf spot, northern corn leaf blight, and tar spot in corn (Figure 1 and 3), and frogeye leaf spot, downy mildew and Septoria brown spot in soybean (Figure 2). In addition, we continue to add counties with active tar spot and southern rust in Indiana. The most frequent question I have received is, “Should we make a fungicide application?” My response – What diseases are you finding in your field? What is your hybrid/variety susceptibility and field history? What growth stage? Are you irrigating? A fungicide application can be effective at reducing disease and protecting yield, but there are a number of factors that need to consider: the field[Read More…]









Purdue Extension Soybean Specialist Shaun Casteel and Corn Specialist Dan Quinn are back for another episode of the Purdue Crop Chat Podcast. On this episode, the guys discuss the most recent crop condition ratings and compare that to what they’re seeing around the state. Casteel also discusses the advantages to having a drone to scout your field at this point in the season.
