Poison-ivy can be controlled by grubbing (digging) out the roots and stems as well as by the use of certain herbicides (chemical weed-killers). Herbicides offer some advantages over mechanical methods. The danger of a person receiving poison-ivy dermatitis either by direct contact with the plant or indirectly by touching contaminated tools, etc., is much less with herbicidal methods than with mechanical methods. Control of the weed is usually simpler and more effective by the careful and correct use of herbicides than by mechanical methods (It is almost impossible to remove every piece of underground stem so regrowth is likely to occur.)
However, all of the
herbicides which kill poison-ivy may also kill or damage other plants growing
nearby. If poison-ivy is growing among perennial ornamentals, in a hedge, or
entwined about a favorite tree, one must resort to cutting and digging to
destroy it. Wear gloves and other protection while cutting and grubbing. Take
care also to prevent other persons from being inadvertently contaminated by the
tools, the roots, stems and leaves.
(chemical weed-killers) have been used effectively for providing good control.
However these chemical cannot be use in public parks, school yards or next to water bodies.
