Question:

I’ve got a grower concerned about getting a later season flush of weeds on peanut land, primarily pigweed, as there have been issues in past years. He is considering cultivating, and applying dual & pursuit. I was curious if you had any insight on the residual this would have for decreasing later emerging pigweed, or if you knew of something else that would work better for this task?

Answer:

I would avoid cultivation as that will bring up additional weed seed and essentially create another flush. I would try to control the weeds with POST herbicides and include Dual Magnum or Warrant in with the spray program and hope the residual gets activated. If pigweeds are a real big issue and he needs to make two more POST sprays (which most fields will need) I would include Dual Magnum with the next POST and Warrant with the distant future POST spray (probably a month from now.) That is a lot of money but I think if you cultivate you are doing away with gains you had with your PPI or PRE programs. Pursuit is rather expensive for what it gives and there may be ALS resistant Palmer amaranth in those fields.
