A field after application of a herbicide Weeds controlled with herbicide. Herbicides (US: / ˈ ɜːr b ɪ s aɪ d z /, UK: / ˈ h ɜːr-/), also commonly known as weed killers, are substances used to control undesired plants, also known as weeds. [1]

An herbicide is an agent, usually chemical, for killing or inhibiting the growth of unwanted plants, such as weeds, invasive species, or agricultural pests. A great advantage of chemical herbicides over mechanical weed control is the ease of application, which often saves on the cost of labor.

2025年2月7日 · This herbicide is applied to the soil to control target vegetation by inhibiting or disrupting cell division in shoots. Adapted from Ross and Childs (1996) and USDA; commercial names in italics. Herbicides may cause biological impairments of water bodies if they occur in water or sediment at sufficient concentrations.

2021年12月7日 · Knowing how herbicides work and how to use them safely is important for both agricultural producers and home gardeners. This publication describes the symptoms of each category of herbicides (growth regulators, photosynthesis inhibitors, etc.), and lists products by common and trade names.

Herbicides, chemicals designed specifically to kill weeds, account for nearly 60% of all pesticide sales in the U.S. U.S. farmers spent an estimated $5.63 billion in 1998 for herbicides, with about $1.1 billion more spent in application costs. Herbicide use declined in 1999 to only a little more than $5.0 billion (Donaldson et. al., 2002).

2007年4月2日 · Understanding herbicide mode of action is helpful in knowing what groups of weeds are killed, specifying application techniques, diagnosing herbicide injury problems, and preventing herbicide-resistant weeds.

HERBICIDE CLASSIFICATION by MODE OF ACTION (effect on plant growth) This chart groups herbicides by their modes of action to assist you in selecting by PREMIX herbicides 1) to maintain greater diversity in herbicide use and 2) to rotate among effective herbicides with different sites of action to delay the development of herbicide resistance.

2021年1月1日 · Herbicide use is very common in agrochemical-based agriculture, especially due to the promotion of herbicide-tolerant genetically modified crops. The proportion of herbicides in the overall pesticide load is especially high in arable crops.

2025年2月5日 · In late August 2024, the U.S. Environmental Protection Agency (EPA) released the final version of its Herbicide Strategy.
