A: A weed is any plant growing where it doesn't meet your management plans. A noxious weed is a plant that is declared noxious, by the state or county, because it causes significant economic impacts within the state and/or county. An invading weed is a non-native plant that is newly established within the state/county and poses a threat of gaining noxious weed status.
A: We spray noxious weeds on pasture, rangeland, road sides, railroads, and ditch banks. We do not spray weeds in residential lawns, crops, or parking areas. Private companies will be happy to spray these areas for you or you can find information about residential weed control here.
A: We are committed by state law and county policy, to spray weeds on the state/county noxious weed list.
A: This is a difficult question to answer because many species of noxious weeds respond better at certain times of the year or with different herbicides. Generally, most plants respond well to herbicides in early growth stages, particularly annuals and biennials. Many perennials also respond well to fall applications of herbicide. However, a chemical that eradicates one weed may not affect another. Federal laws describe what chemicals may be used and where they may be applied. This information can be found on the label on the herbicide container. Read the labels. Contact the Vegetation Management Division for detailed information.
A: An excellent source for calibration can be found here.
A: Absolutely! Most annuals and biennials can be controlled by hand pulling or tillage. Biocontrol (pathogens, insects, herbivores, etc.) are available for several noxious weed species and can be used effectively in some large scale situations to reduce noxious weed populations, contact USDA-APHIS or the weed division for specifics. Competitive vegetation may be introduced or re-introduced to help control noxious weeds. However, these methods usually take a long time and likely will not eradicate the weed problem. These methods are meant to reduce noxious weeds to tolerable levels within the ecosystem. Fire without replanting competitive species generally exacerbates the noxious weed problem by increasing resources available to noxious weeds.
A: No, we don't. You can find information about the Cache Mosquito Abatement District here. You may also call one of the local pest control companies
