Eastern Washington State | I have a WeedIt, we have kochia where I'm at, but its not nearly the problem it is other places. RoundUp + Group 4s still works well on it for us. Early in the summer here is what I've been using with my WeedIt:
- 32 oz RT3 or equivalent
- 8 oz LV-6
- 2.66 oz Dicamba
- 1 qt LI700
- 5 qt/100 liquid AMS - this is how much I need to treat the hardness of my water, your water might need a very different amount.
- 7.5 GPA
Later in the summer I switch over to a paraquat based mix, this is not a cheap mix and not something you are going to want to spray broadcast over every acre, but with a spot sprayer its liquid fire. Its three modes of action and completely different than my mixes I use earlier in the season. I'm not messing around when it comes to herbicide resistance.
- 32 oz Paraquat
- 8 oz 2 lb Bromoxynil
- .8 oz Vida or Aim - Vida requires a water pH below 5.0, I treat my water with citric acid to get it below 5 beforehand.
- 2 qt/100 High surfactant oil concentrate
- 3 gal/100 UAN
- 5 qt/100 liquid AMS - - this is how much I need to treat the hardness of my water, your water might need a very different amount.
- 30 GPA
For my very last application of the summer when I'm applying to < 5% of the field I'll increase the paraquat/Vida to 32 oz/1.2 oz. I don't know if it necessary but when so few acres are getting sprayed its cheap insurance.
