From the Field Updates
What a wild ride this season has been. A lot of work and crop progress has occurred over the last month of July. As of two weeks ago, the last top dress rig was sent out on 300 acres of sweet corn, so outside of alfalfa spraying and R3 work on beans, custom work has wrapped up.
Corn: We’ve been tendering helicopters & planes that are doing some post-brown silk fungicide spraying on corn the last couple weeks. In the past, Delaro has worked well for late season work, so we’re using that again this year. Weed pressure has been held at bay – in some cases, with just a SOLID pre-emerge program. Disease wise, there has been Tar Spot identified in some counties in WI and northern IL – Rock and Lafayette counties in WI and DeKalb county in IL. Given the year, corn is looking good!
Soybeans: R3 work (top 4 branches/nodes showing a pod that’s ¼” in length) has been in full swing for the last two weeks. In my opinion, beans like to be stressed early and pampered late, so a solid R3 program containing a fungicide, insecticide, and foliar micro-nutrient blend is ideal.
Alfalfa: I’ve seen and had more calls on alfalfa these last 2 weeks than in years past. One answer to many issues is sulfur deficiency when the entire plant is yellow or chlorotic in color – especially if nothing has been applied this year or has only been applied in early spring before all the rains. The second most common issue I’m seeing is aphid and leaf hopper pressure when sweeping the fields. Good news, there is an insecticide/drift control pass (Mustang Maxx with InterLock) which is very affordable.
