Disease Management: Foliar Fungicide May Have Provided Yield Increase to Soybeans
We have conducted numerous studies over the last 10 years on soybean seeding rates. In almost all instances, we rarely observed a response to rates above 150,000 seeds/acre. In 2015, we examined the response of soybean under high input management (~200,000 seeds/acre with a fungicide/insecticide seed treatment as well as a foliar fungicide, Priaxor, applied at 4 fluid oz. /acre on 7/31 at the R3 stage) compared with recommended input management (150,000 seeds/acre with a fungicide/insecticide seed treatment). This was part of a larger study comparing the response of all the crops in the corn-soybean-wheat/red clover rotation under conventional and [...]
