Agricultural chemistry is the chemistry, especially organic chemistry and biochemistry, as they relate to agriculture. Agricultural chemistry embraces the structures and chemical reactions relevant in the production, protection, and use of crops and livestock .
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 use of herbicides in US agriculture is mapped by the US Geological Survey. As of 2019 [update] , 2,4-D was the most used of the auxins. 45,000,000 pounds (20,000,000 kg) were sprayed that year, [ 5 ] compared to 2,000,000 pounds (910,000 kg) of the next most heavily applied, MCPA. [ 6 ]
The use of herbicides as a chemical weapon by the U.S. military during the Vietnam War has left tangible, long-term impacts upon the Vietnamese people and U.S soldiers that handled the chemicals. [ 37 ] [ 38 ] More than 20% of South Vietnam's forests and 3.2% of its cultivated land were sprayed at least once between during the war. [ 39 ]
This is a list of fungicides.These are chemical compounds which have been registered as agricultural fungicides.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]
Like other pesticides, fungicides are numerous and diverse.This complexity has led to diverse schemes for classifying fungicides. Classifications are based on inorganic (elemental sulfur and copper salts) vs organic, chemical structures (dithiocarbamates vs phthalimides), and, most successfully, mechanism of action (MOA).
The industry-sponsored Insecticide Resistance Action Committee (IRAC) advises on the use of insecticides in crop protection and classifies the available compounds according to their chemical classes and mechanism of action so as to manage the risks of pesticide resistance developing. [4]
The word pesticide derives from the Latin pestis (plague) and caedere (kill). [5]The Food and Agriculture Organization (FAO) has defined pesticide as: . any substance or mixture of substances intended for preventing, destroying, or controlling any pest, including vectors of human or animal disease, unwanted species of plants or animals, causing harm during or otherwise interfering with the ...
