Harvest is soon to be underway as summer gives way to the fall, and that is the time when growers need to think about getting a clean start next spring. For growers having problems with chickweed and marestail, a fall burndown program can provide good benefits.
“Fall is the best time to really deal with winter annuals,” says FMC Senior Technical Sales Manager Brent Neuberger. “You can apply a product to kill what is up but also a product that gives you some residual so come next spring you have a clean seed bed.”
The two main products FMC recommends for fall application are Authority XL and Authority MTZ.
Authority XL provides a good residual and burndown for the grower who is going to plant soybeans again while Authority MTZ provides more flexibility from a crop rotation standpoint. A grower can come back with corn or soybeans after applying Authority MTZ if you use less than 14 oz. The ideal time to begin the process is when the temperature drops down to 55 degrees or below but to be effective, Authority needs to be applied prior to the ground freezing.
