You better read that basagran label. Lond term residual
I just went back and looked at the Winfield and BASF labels and saw nothing on plant back restrictions or residuals. There are grazing restrictions. It is labeled for the following crops : Alfalfa, clover, soybeans, corn, sorghum and has no effect on grasses. Maximum rate is 4 pints per acre per year. If you have information on residuals, please share it.
