Has anyone figured out a chemical control for spot treatment of milkweed that is not restricted? I know that rup will work, just trying to not have my wife walk aimlessly around the field painting milkweed plants. Seems like they thrive when the ground is rock hard and therefore hoeing them is not an option. I think spraying is the only way to get the tuber. I have a mess of them in my new og field and I want them gone. Thanks.
2-4d overspray and 5 years is the most environmental way.....you have to spray for them about twice a season....after emerging....and then later in the summer they re-emerge. Keeping them suppressed starves their root system....but it takes a long time.
Milestone is very over-rated here in the South. I used it for about 5 years on some hard to control perennials weeds and it never killed them. Too expensive for that kind of result. I could have gotten suppression a whole lot cheaper....and suppression is not what I was looking for. I have had better results with Pasturegard than I have with Milestone.
"Few herbicides are good on milkweed. In university testing, the best results were obtained with products containing the active ingredients aminopyralid and/or fluroxypyr; examples include GrazonNext HL and Surmount. A high rate of dicamba (32-64 oz/acre) can also be effective, but can injure grasses during periods of stress. Surmount is a restricted-use product. Surmount and GrazonNext HL are labeled for pasture only."
Also think dicamba and 2,4 D (Weedmaster) might be a good choice.
I have the Antelope horn variety on my place. I tried Grazon HL with no effect. I tried Cimmaron Max on another pasture with the same result. I'm at the point of using Eraser with a surfactant in a pump sprayer. I fly a desk all day so aimlessly wandering the pastures with a pump sprayer seems to be my exercise ethic every weekend.
