Noxious and Troublesome Weeds

A Guide to North Dakota Noxious and Troublesome Weeds - W1691

This guide was made with collaboration of the author with the North Dakota State University Extension Service and the North Dakota Department of Agriculture, with funding from the U.S. Forest Service. This publication is designed to help land managers identify the state- or county-listed noxious weeds. Other species included are those with the most potential to spread within the state or into North Dakota from bordering states.

Invasive and Troublesome Weeds in ND

Identification and Control of Invasive and Troublesome Weeds in North Dakota - W1411

Th is publication is intended to help land managers properly identify and control noxious and invasive weeds found in the state. Th e current list of 11 noxious weeds are included, as well as species listed by various counties as noxious. Other species included are either invasive weeds found in bordering states with the potential to move into North Dakota or are commonly misidentifi ed native species that do not require control eff orts, such as the native thistles.

Spray Equipment and Calibration

Spray Equipment and Calibration - AE73

Many pesticides used to control weeds, insects, and disease in field crops, ornamentals, turf, fruits, vegetables, and rights-of-way are applied with hydraulic sprayers. Tractor- mounted, pull-type, pickup-mounted and self-propelled sprayers are available from numerous manufacturers to do all types of spraying.

Thistles of ND

The Thistles of North Dakota - W1120

Thistles in agriculture have a reputation as a sign of untidiness and neglect, and are often found on good ground not properly cared for. However, this unfortunate characteristic is only true of a few invasive species and is not accurate for the vast majority of native thistles which have many useful traits.

Spotted Knapweed

Spotted Knapweed (Centaurea maculosa Lam.) - W842

Spotted knapweed is an aggressive, introduced weed species that rapidly invades pasture, rangeland and fallow land and causes a serious decline in forage and crop production. The weed is a prolific seed producer with 1000 or more seeds per plant. Seed remains viable in the soil five years or more, so infestations may occur a number of years after vegetative plants have been eliminated. Spotted knapweed has few natural enemies and is consumed by livestock only when other vegetation is unavailable. The plant releases a toxin that reduces growth of forage species. Areas heavily infested with spotted knapweed often must be reseeded once the plant is controlled.

Perennial and Biennial Thistle Control

Perennial and Biennial Thistle Control - W799

Thistles are especially troublesome following cool, wet summers and falls, when seed production and seedling establishment are high. An integrated weed control program that combines chemical, cultural (such as crop rotation or grass competition), mechanical and biological methods is most likely to be successful.

Leafy Spurge Control Using Flea Beetles

Leafy Spurge Control Using Flea Beetles - W1183

Leafy spurge is an exotic perennial weed that infests over 800,000 acres in North Dakota. Although leafy spurge can be successfully controlled with herbicides, treating large acreages is not cost-effective. In fact, approximately 40 percent of the leafy spurge infested rangeland has a carrying capacity below the herbicide cost break-even point. Using biological agents to control leafy spurge has become an economic alternative in many locations in the state.

Integrated Management of Leafy Spurge

Integrated Management of Leafy Spurge - W866

Leafy spurge is the most difficult noxious weed to control in North Dakota and infests all 53 counties in a variety of environments. Leafy spurge is found in pasture, rangeland, cropland, roadsides, shelterbelts, and other non-cultivated areas. Cultivation will control leafy spurge in conventional cropland, but the weed can become the dominant species in reduced-till cropland, pas-ture, and rangeland if not controlled.

Know Your Knapweeds

Know Your Knapweeds - W1146

North Dakota is being threatened by three noxious weeds that could infest more acreage in the state and at a faster rate than leafy spurge. Members of this trio include spotted, diffuse, and Russian knapweed. These three knapweeds already infest more acreage than leafy spurge in Montana and Minnesota, and have been found in over 25 counties in North Dakota. Knapweeds are related to thistles and can spread even faster.

ID and Control of Purple Loosestrife

Identification and Control of Purple Loosestrife (Lythrum salicaria L.) - W1132

Purple loosestrife, a beautiful garden plant with an aggressive nature, was first introduced into North America in the early 1800s. The plant was sold in North Dakota by its genus name Lythrum for at least 50 years. Lythrum plants were brought to North Dakota for flower gardens because of their striking color, ease of growth, winter hardiness, and lack of insect or disease problems. The garden varieties of purple loosestrife were sold by many cultivar names including Morden Pink, Drop-more Purple, and Morden Gleam. These garden cultivars were thought to be sterile but have now been shown to cross-pollinate with the wild Lythrum type and sometimes with other Lythrum cultivars.

Houndstongue ID and Control

Houndstongue (Cynoglossum officinale L.) Identification and Control - Stop the Spread - W1307

Houndstongue is a biennial, poisonous herb that is native to Eurasia. The plant is a member of the Borage family, which includes more commonly known plants such as Virginia bluebells, forget-me-nots and the fiddlenecks. Houndstongue commonly is found in disturbed areas, including roadsides and trails, and in pasture and woodlands following soil disturbance or overgrazing.

Biennial Wormwood

Biology and Management of Biennial Wormwood - W1322

Biennial wormwood is an aggressive and prolific seed-producing plant that has become a problem mainly in soybean and dry edible bean production areas of Minnesota, North Dakota and South Dakota. Biennial wormwood, as its name infers, was primarily biennial when the species fi rst was classified, but weedy cropland biotypes of biennial wormwood are annual plants. Many factors, such as season-long emergence, prevalence in moist environments, adaptation to all tillage systems, tolerance to commonly used soil-applied and postemergence herbicides, and misidentification of biennial wormwood as common ragweed, contribute to increased biennial wormwood infestations. Some herbicides used to control common ragweed do not control biennial wormwood.
