MNL Weed Control Mix

A mix of Clopyralid resistant species to aid in invasive weed control 

Diverse mix of grasses & wildflowers that are Clopyralid resistant for effective weed control without loss of mix diversity. This mix was specially designed for use in sites with a history of weed pressure from a mix of undesirable invasive weeds, such as: Canada thistle, bur dock, spotted knapweed, sweet clover, and more. The flowering species in this mix were chosen because of their resistance to Clopyralid herbicides, making future weed management more effective without losing diversity of native species. Each seed mix order will ship with an appropriate amount of cover crop seed for the project area – species of cover crop seed will depend on the time of year the product is ordered (if you have a delayed planting time in mind, please indicate that in a note at check out).
