When considering fungicide applications this year, timing is something to carefully manage. In any crop this is important, but especially when looking at soybeans. Determining the proper growth stage to spray at is a must. This is why an aerial application could be a strong choice for this year’s applications. The track damage caused by a ground rig is unavoidable, but can be made worse depending on how vulnerable the beans are.
According to UW-Madison soybean specialist Shawn Conley, when soybeans begin to flower at R1, they become more susceptible to wheel track damage. At this reproductive stage, there is a small window of time for applications to be made. The problem with wheel tracks come down to yield loss. At the R3 stage, when pods are starting to develop, soybeans will pay the price of wheel track damage. Purdue University Extension shared data from an estimated impact of boom width on grain yield loss per acre from wheel track damage. The averages of yield loss per acre are below:
Boom Size- (Yield loss per acre):
30- (4.9%), 60- (2.5%), 90- (1.9%), 120- (1.3%)
Research has also shown that soybeans in narrow roads, late-planted beans, and thin stands are more vulnerable. With faster speeds in a ground rig, avoiding plant damage could be difficult.
We see many benefits using an airplanes capability when applying fungicides to your soybeans this year. There is no wheel track damage, uniform spray coverage, zero compaction, and a faster application. This is why we have designed our Soybean Aerial Assault discount program. Why wait to commit to aerial applications until later? From now until April 1st, if you pre-pay for your aerial application, we will take $2.00 off. Our associate partners would be happy to assist in application recommendations and foliar nutritional additives. This saves not only your soybean bushels, but your budget as well.
