West-Central Missouri | I have been using sulfentrazone for preplant residual in soybeans. The last 2 years, I have used 7 oz. Authority Supreme & 3 oz Authority XL.
I always have let it get rained in before planting. So far i have never had soybean damage from it.
I really am impressed with how long the residual holds even with lots of rain. Currently i am at 40 days with no weeds breaking through yet, even though it has had @ 10” rain on it.
My question is, even though i see no damage, could it still be causing yield loss compared to using pyroxasulfone?
