The discovery of poison ivy in the vicinity of a business or residence is always a cause for concern. Poison ivy often grows amid other types of plants and goes undetected for some time. Property owners or managers who have discovered poison ivy can rest assured that the problem can be eliminated by the proper use of herbicides.

Herbicide Basics

The action necessary to eliminate poison ivy is to spray the green leaves with herbicide. To avoid excessive dilution, the herbicide is applied when rain is not in the immediate forecast. The effect of herbicide on poison ivy is systemic. The herbicide is absorbed by the leaves and gradually drawn into the stems and roots of the plant system.

After a few days, the leaves start to change color from green to yellow. The yellow leaves then turn to brown and shrivel. Within roughly a couple weeks from the initial spraying, the shriveled plants are dead. Because poison ivy sometimes appears alongside your desired plants, a strategic approach may be necessary.

Protection of desired plants

Poison ivy is categorized as a broad-leaf weed and is controlled by the same herbicides that kill various broad-leaf weeds, so grass is typically safe. The location of poison ivy in relation to your other plants largely determines which herbicide is best suited for your particular parcel of land. All your desired flowers and shrubs can be safeguarded, and the poison ivy is strategically exterminated.

Broad coverage of glyphosate

Glyphosate is referred to as a nonselective herbicide and is also intended for controlling grass. Glyphosate can be directly sprayed on poison ivy, or it can be used to additionally control the weeds and grass surrounding the poison ivy. The consistency of the spray from a pressurized sprayer is adjustable, so herbicide may be applied as a mist or as a steady stream.

Targeted application of triclopyr

Triclopyr is a selective herbicide. It eliminates poison ivy and broad-leaf weeds, but it does not affect grass. Triclopyr is more effective at controlling tougher, woody weeds.

Poison ivy sometimes grows as a climbing vine. Thicker vines are carefully severed above the ground, and triclopyr is applied to the stump of the vine. Triclopyr is absorbed through the open cut and drawn into the root system.

The presence of poison ivy detracts from your ability to fully utilize all your land. Contact a landscape professional, like C S Flournoy Inc, for more information about poison ivy control or to receive advice on other uses of herbicide.
