If not, what do you recommend?
Tordon RTU Specialty Herbicide is not labeled specifically to control prickly pear or other cacti, but some articles recommend this active ingredient to aid in control. One very difficult part of controlling this plant is that all debris must be removed from the area to prevent resprouting. Unfortunately, we do not have any herbicides currently labeled to control cactus. This Field Guide from the USDA discusses control methods for prickly pear cactus. Another active ingredient mentioned is Fluroxypyr, which we do have in the product E-2 Herbicide. We recommend consulting your local Cooperative Extension office for assistance. Since this is a heavily invasive species of importance, most local offices will want to know where the plant is being found.
