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]
Penoxsulam is sulfonamide and triazolopyrimidine herbicide that acts as an acetolactate synthase inhibitor. [1] [2] It is primarily used for rice production. [3]
Atrazine was invented in 1958 in the Geigy laboratories as the second of a series of 1,3,5-triazines. [26] Atrazine is prepared from cyanuric chloride, which is treated sequentially with ethylamine and isopropylamine. Like other triazine herbicides, atrazine functions by binding to the plastoquinone-binding protein in photosystem II, which ...
The triazine family of herbicides, which includes atrazine, was introduced in the 1950s; they have the current distinction of being the herbicide family of greatest concern regarding groundwater contamination. Atrazine does not break down readily (within a few weeks) after being applied to soils of above-neutral pH. Under alkaline soil ...
Terbuthylazine is a selective herbicide.Chemically, it is a halogenated triazine; compared with atrazine (1958 inv., Geigy lab) and simazine, it has a tert-butyl group −[C−(CH 3) 3] in place of the isopropyl −[CH−(CH 3) 2] and ethyl group, respectively.
Alachlor mixes well with other herbicides. It is marketed in mixed formulations with atrazine, glyphosate, trifluralin and imazaquin. It is a selective, systemic herbicide, absorbed by germinating shoots and by roots.
Atrazine Chlorohydrolase (AtzA) is an enzyme (E.C.3.8.1.8), [1] which catalyzes the conversion of atrazine to hydroxyatrazine. Bacterial degradation determines the environmental impact and efficacy of an herbicide or pesticide. Initially, most pesticides are highly effective and show minimal bacterial degradation; however, bacteria can rapidly ...
