	Weed-feeders Introduction
		Using biological agents for weed control is beneficial because there is less overall expense compared to herbicidal sprays.
		Traditional methods of weed control, such as cultivation and the use of herbicides, are not practical or desirable for such wide-ranging stands of weeds, and biological control has become an attractive strategy for control of pest weeds.
		In the U.S., it is estimated that 50% to 75% of problem weeds were either accidental or intentional introductions from other areas.

	Understanding Montana's Noxious Weed Law, from the MSU Extension Service
		Noxious weeds are defined by this act as being any exotic plant species which may render land unfit for agriculture, forestry, livestock, wildlife or other beneficial uses or that may harm native plant communities.
		Under the noxious weed law, embargo programs may be implemented to reduce the spread of noxious weeds within the county or to prevent the introduction of noxious weeds into the county.
		After the establishment of a county weed management district, a county weed board is appointed by the county commissioners of each district to oversee responsibilities established by the noxious weed control law.

	Plants and Society Biological Controls
		Table 3 is a list of combinations of vegetables, herbs, flowers, and weeds that are mutually beneficial according to empirical information, primarily from current reports of organic gardeners and companion planting traditions.
		In 1974, the Weed Science Society of America published a special committee report (Weed Science 22:490-95) on the biological control of weeds, summarizing the status of projects on the biological control of weeds with insects and plant pathogens in the United States and Canada.
		In undisturbed natural areas, weeds are never a problem, and even though pests may be present, they seldom destroy the community.

	Breezeco - Noxious Weed Prevention
		Noxious weeds are a non-indigenous invasive plant, which often crowd out beneficial plants, creating a "monoculture" of just themselves.
		The best way to manage Noxious Weeds is by controlling the spread of their seeds and rhizomes to uninfected areas.
		The Breezeco method was designed to address one of the most common causes of new noxious weed infestation, vehicle and machinery transport.

	Putting the Brakes on Mile-a-Minute Weed
		Mile-a-minute weed has been on the march ever since, depriving indigenous plants of sunlight and often out-competing natives in spring seeding.
		The U.S. Department of Agriculture Forest Service counting on the weevil's voracious appetite for mile-a-minute weed, which is native to China, to disrupt the invasive weed's onslaught, thus protecting native vegetation.
		Following the official release in White Clay Creek Park, a number of Asian weevils were transported to the Phillip Alampi Beneficial Insect Rearing Laboratory in Trenton, N. J., where researchers hope to find a way to rear the weevil quickly -the greater number available for release, the faster results will be seen.

	Biological Control of Plant Pests
		These beneficial insects help control damaging weeds and insects, and reduce the amount of pesticides that farmers and gardeners would otherwise use, as well as assist in the conservation of natural enemies that would be impacted by the use of broad-spectrum pesticides.
		Purple Loosestrife is an exotic and invasive noxious weed that is threatening New Jersey's wetlands.
		The Department is rearing and releasing two species of leaf eating beetles, Galerucella spp., that feed on purple loosestrife to control this weed pest in wetland areas.

	Noxious Weeds are capable of rapid spreading.
		These weeds are capable of rapid spread and invasion of lands, rendering lands unfit for beneficial uses.
		These weeds are capable of rapid spread and render land unfit or greatly limit beneficial uses.
		Instead, getting weeds under control, i.e., not spreading and not choking out native growth, is an outcome to strive for.

	Simulated Hail Damage on Guar
		The guar variety Kinman was planted on 11 June 2002 in a Miles fine sandy loam on a conventional-tilled field to achieve a population of about 3 to 4 plants/ft. After guar emergence plots were maintained and kept weed-free via chemical weed control or hand hoeing.
		Currently, guar bean splits (germ removed) are imported from either Pakistan or India; therefore, development and promotion of guar production would be beneficial to agriculture in this area and supply an alternative source of the raw material for U. processing plants.
		Hail has been shown to decimate a field of corn or soybean beyond the point where it is economically beneficial for the farmer to harvest the crop.

	Year: 1996
		Project Title: Weed Suppression and Enhancement of Wildlife and Beneficial Insect Habitat in Center Pivot Irrigated Field Borders and Corners
		In the long-term, these re-vegetated corners might harbor wildlife and beneficial insects that would prey on pests in the adjacent crops.
		These native grasses, forbs, and shrubs would compete against weedy species and, in the long-term, reduce weed seed in adjacent fields and reduce herbicide use.

	Preventing Chemical Foodborne Illness
		Examples of beneficial chemicals (Table 1) are some of the metals and vitamins (nutrients), nitrite (a preservative), monosodium glutamate (a flavor enhancer), pesticides (for insect, weed and rodent control) and cleaners (for environmental hygiene).
		Some of the known chemical agents involved in chemical foodborne illness are beneficial and essential in the diet as nutrients, others serve to preserve food or improve eating quality, while others are beneficial in food production or to assure a clean and sanitary food handling environment.
		Chemical foodborne illness is normally the result of a human error that could have been prevented.

	County Of Marin: Agricultural Weights and Measures - Integrated Pest Management (IPM) Program
		We have established a Weed Management Area in the County where pest weeds are removed mechanically and beneficial control agents are released to suppress weed populations through natural biological control.
		IPM, or Integrated Pest Management, is an approach to pest control that is based on an understanding of the pest’s life cycle and habits.
		The goal of IPM is long-term pest control; therefore, emphasis is placed on preventing pests and on eliminating their habitat.

	Beware of Sour Mulch
		Mulching garden or landscape plants with bark, straw, leaf, or sawdust mulch can be beneficial to plants in a number of ways.
		Mulch not only helps conserve moisture around plants, but also serves as a barrier to weed growth and can be an effective method of weed control.
		Toxicity of sour mulch is caused by by-products of the decomposition process, such as methane, alcohol, ammonia gas, or hydrogen sulfide gas, that build up to levels toxic to plant growth.

	Musk Thistle Biological Control Plan
		The goal of each of the biological pest control programs is to successfully establish beneficial insects in a situation where access for collection and redistribution is possible.
		When a plant species, such as musk thistle, has been introduced into a new land and is not held in check by local or accompanying natural biological controlling agents, it often becomes a problem and is labeled as a "weed" or a "noxious weed," depending on its impact on the rancher or farmer.
		It is necessary for pest populations to be maintained while proliferation of the exotic parasites and predators occurs.

	Current advances in bioherbicide research
		A bioherbicide is a preparation of living inoculum of a plant pathogen, formulated, and applied in a manner analogous to that of a chemical herbicide in an effort to control or suppress the growth of weed species.
		The bioherbicide approach is an attempt to bypass many of these restraints on disease development by periodically dispersing an abundant supply of virulent inoculum uniformly onto a susceptible weed population.
		Therefore, the term "mycoherbicide" has often been used interchangeably with "bioherbicide." In addition the term "bioherbicide" is generally restricted to the use of plant pathogens and does not include attempts to augment populations of beneficial insects, nor does it generally include the use of naturally occurring compounds (phytotoxins) produced by microorganisms.

	Teosinte - Wikipedia, the free encyclopedia
		In some areas of Mexico, teosintes are regarded by maize farmers as a noxious weed, while in a few areas farmers regard it as a beneficial companion plant, and encourage introgression.
		There is currently a large amount of scientific interest in conferring beneficial teosinte traits, such as insect resistance, perennialism and flood tolerance, to cultivated maize lines, although this is very difficult due to linked deleterious teosinte traits.
		There are five recognized species of teosinte: Zea diploperennis, Zea perennis, Zea luxurians, Zea nicaraguensis and Zea mays.

	Managing Saskatchewan Rangeland
		This is particularly beneficial on rangeland where a mixture of grasses and forbs are desired.
		True range weeds invade rangeland or pasture and are not part of the natural plant complex.
		Although the term "weed" is often used to refer to undesirable rangeland and pasture species, a weed is any plant growing out of place.

	Veganic Gardening
		Weeding is a constant task for the vegan organic grower but it is always easier to hoe small weeds when they are at the white stringy stage rather than having to up root established weed clumps by hand which is far more arduous.
		Beneficial insects, birds and mammals will not inhabit your garden unless they have a water body in which to drink and places to shelter.
		Vegans buying or growing their own food may also believe that the prospect of growing organically without animal derived material is impractical or downright impossible.
