NW Wisconsin | Metribuzin increases efficacy in higher Ph soils therefore you can lower the rate and get similar control.
UW has done plenty of research on MTZ and PPO in soybeans... If you dont like splash damage from PPO spray early. 1 Rain and the risk basically disapears. MTZ look at your soil test look at the label. 7ph 4-5 oz works good.
I spray a ton of prefix because of the shortened season up here. Same efficiacy as Sulfentrazone and valor but with the flexibility to go post emergence. Soil applied PPO's are the best thing against waterhemp. | |
