CrossCut Select like other herbicides has a 3-5 year shelf life if kept out of extreme temperatures and direct sunlight.
You would use a stump killer on fresh cut stumps such as the CrossCut.
CrossCut Select Weed and Brush Herbicide should not be applied in desired areas. It should only be applied to the following locations:
Rangeland, Permanent Grass Pastures, Conservation Reserve Program (CRP) acres, Commercial Turf, Sod Farms, Fence Rows, Non-Irrigation Ditch Banks, Roadsides, specified Non-Crop areas and Industrial sites. We would recommend carefully spot treating with a glyphosate product.
