I am a small, older woman and plan to cut the smaller buckthorn plants to the ground, then spray with Remedy Ultra. For the larger buckthorn trees someone will help me cut them to the ground. Can I spray the stumps in the same way? My Remedy Ultra supply is more than three years old. Is it still effective, perhaps with less diluting?
The mixing ratio of Remedy Ultra Herbicide is 1.28 - 1.92 fl. oz. per gallon of water for spot treatments. For smaller volume treatments, a 1 gallon hand pump sprayer needs to be used, this should not be applied using a hand held trigger spray bottle.
For stump treatments, you would use 25 fl oz to 38.4 fl oz per gallon of water, being sure to get the outer layers and cambium of the stump. You will still need to remove the stumps and root systems physically after using herbicides to stop regrowth.
Remedy Ultra Herbicide has a shelf life of 3 to 5 years if stored out of extreme temperatures (heat/freezing) and out of direct sunlight.
