 20 miles west of Indianapolis Indiana | Hopefully someone tells me I’m wrong. But I don’t feel like you can “clean up” marestale or waterhemp like other weeds. I feel stopping them from emerging is what sets some farms apart and makes one think farmer A has a lower seed bank than farmer B when it is really just keeping them from emerging.
Marestale IMO needs a 2 shot approach and will make you look like a star if you do a fall and spring burndown both and a spring residual. One year I didn’t use Metrabuzin in my spring pre on a couple farms and I had bad marestale on them even with spring burndown on it. Marestale is one of the weeds tillage helps to reduce but doesn’t get rid of it.
Fall 24D and Dicamba and spring 24D, Metrabuzin and your favorite pre(s) will usually keep it at bay well.
Do you have waterhemp? If you don’t when it shows up it’ll make marestale seem like Childs play. We have a lot of good growers in my neighborhood who have perfectly clean plentish (RR only) fields of just Beans and waterhemp. (Probably a few marestale too but the waterhemp are shading them) |
