This is a list of herbicides.These are chemical compounds which have been registered as herbicides.The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [1]
The detailed mechanism of action for nitrofen, acifluorfen and related diphenyl ether herbicides was unknown at the time they were invented. The effects visible on whole plants are chlorosis and desiccation: several hypotheses were advanced regarding the molecular-level interactions which might explain these symptoms. [11]
The biological activity of a pesticide, be it chemical or biological in nature, is determined by its active ingredient (AI - also called the active substance). Pesticide products very rarely consist of the pure active ingredient.
The purpose of the label is to "provide clear directions for effective product performance while minimizing risk to human health and the environment." A label is a legally binding document that mandates how the pesticide can and must be used and failure to follow the label as written when using the pesticide is a federal offense. [4]
Tebuthiuron is a nonselective broad spectrum herbicide of the urea class. It is used to control weeds, woody and herbaceous plants, and sugar cane. [1] It is absorbed by the roots and transported to the leaves, where it inhibits photosynthesis.
One major complication to the use of herbicides for weed control is the ability of plants to evolve herbicide resistance, rendering the herbicides ineffective against target plants. Out of 31 known herbicide modes of action, weeds have evolved resistance to 21. 268 plant species are known to have evolved herbicide resistance at least once. [59]
Chlorpropham or CIPC is a plant growth regulator and herbicide used as a sprout suppressant for grass weeds, alfalfa, lima and snap beans, blueberries, cane fruit, carrots, cranberries, ladino clover, garlic, seed grass, onions, spinach, sugar beets, tomatoes, safflower, soybeans, gladioli and woody nursery stock.
Agent Purple is the code name for a powerful herbicide and defoliant used by the U.S. military in their herbicidal warfare program during the Vietnam War. The name comes from the purple stripe painted on the barrels to identify the contents.
