Ada County Weed Pest and Mosquito Abatement
Ada County's 5 Worst Weeds - Poison Hemlock
|
***IMPORTANT NOTE***
According to Idaho Code 22-2407, Idaho property owners carry the primary burden of controlling noxious weeds on their land. County Weed Superintendents may only treat noxious weeds on private property if the landowner fails to fully mitigate the situation. In such instances, the County will treat the noxious weeds and bill the property owner for the weed control efforts.
Poison Hemlock is one of the most common noxious weeds in Ada County. As the name implies, Poison Hemlock contains highly toxic alkaloids and is a health hazard to humans and livestock. This plant is prevalent in poorly drained soils, particularly along rivers, ditches, and in pastures with high water tables. While horses and cows do not find this plant particularly palatable, it can be accidentally ingested while animals are foraging.
Fortunately, Poison Hemlock is easily controlled with herbicides like 2, 4-D, which controls broadleaved plants and works very well on Poison Hemlock. Be careful when selecting the herbicide, since some formulations of 2,4-D are salt based and can make the plants attractive to livestock for a few days after spraying. All grazing restrictions stated on the herbicide label should be observed. If Poison Hemlock is growing near water, herbicide options may change, or special steps might need to be taken to protect our waterways. Under no circumstances should herbicides be sprayed or allowed to drift into any waterway, pond, or stream.
At Ada County Noxious Weed Control, we look forward to discussing your weed control issues with you. We have several spraying trucks and can spray most properties for a fee. If you would like, we can provide an estimate of the cost involved beforehand. If you chose to have us treat your property, we ask that you have your property ready to spray when we arrive. This includes unlocking gates, clearing irrigation pipes, removing livestock, and withholding irrigation long enough for us to get a ¾-ton pickup truck on it without getting stuck. Weather permitting, we normally arrive on the day we have scheduled to spray your property. In the spring, treatments are often made two to three weeks away from when you call us about spraying a property. It is best if you call early to make an appointment. Please tell us if you have any unusual circumstances associated with your spraying needs.
For help controlling a weed control problem, or for clarification about using herbicides, feel free to call Ada County Noxious Weed Control at (208) 577-4646, or visit our office at 975 E. Pine in Meridian. Our office hours are from 7:30 a.m. to 5 p.m. Monday through Friday except holidays.
