Desiccated potato plants prior to harvest. Pre-harvest crop desiccation is the application of an agent to a crop just before harvest to kill the leaves and/or plants so that the crop dries out from environmental conditions, or "dry-down", more quickly and evenly.
Alternatively, spraying after weeds are already present in the crop will also lead to control. The product is used at application rates of 0.008–0.0155 pounds per acre (9.0–17.4 g/ha). [ 16 ] The estimated use in US agriculture is mapped by the US Geological Service and shows that from 1992 to 2017, the latest date for which figures are ...
Mesotrione was introduced in 2002 and like sulcotrione is a triketone, so it is effective on the same weeds and crops, but is more potent, making it more useful in mixes with other herbicides - an important factor for fully controlling weeds and preventing the development of resistance. It has become the biggest selling member of the HPPD class ...
Pendimethalin protects crops like wheat, corn, soybeans, potatoes, cabbage, peas, carrots, and asparagus. It is used to control annual grasses and certain broadleaf weeds which interfere with growth, development, yield and quality of agricultural and horticultural crops by competing on nutrients, water and light.
In the 1970s, agrochemical companies were working to develop new herbicides to be complementary to the auxins. The aim was to find materials which would selectively control grass weeds in broad-leaf crops such as cotton and soybean.

Metolachlor is a popular herbicide in the United States. [3] As originally formulated metolachlor was applied as a racemate , a 1:1 mixture of the ( S )- and ( R )-stereoisomers. The ( R )-enantiomer is less active, and modern production methods afford a higher concentration of S-metolachlor, thus current application rates are far lower than ...
Pesticide degradation is the process by which a pesticide is transformed into a benign substance that is environmentally compatible with the site to which it was applied. . Globally, an estimated 1 to 2.5 million tons of active pesticide ingredients are used each year, mainly in agricult
