2. MCPA - Wikipedia

   en.wikipedia.org/wiki/MCPA

   MCPA is used as an herbicide, generally as its salt or esterified forms. Used thus, it controls broadleaf weeds, including thistle and dock, in cereal crops and pasture. It is selective for plants with broad leaves, and this includes most deciduous trees. Clovers are tolerant at moderate application levels.

3. Glyphosate - Wikipedia

   According to Ian Heap, a weed specialist, who completed his PhD on resistance to multiple herbicides in annual ryegrass (Lolium rigidum) in 1988 [189] – the first case of an herbicide-resistant weed in Australia [190] – by 2014 Lolium rigidum was the "world’s worst herbicide-resistant weed" with instances in "12 countries, 11 sites of ...

4. Clopyralid - Wikipedia

   en.wikipedia.org/wiki/Clopyralid

   Clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) is a selective herbicide used for control of broadleaf weeds, especially thistles and clovers.Clopyralid is in the picolinic acid family of herbicides, which also includes aminopyralid, picloram, triclopyr, and several less common herbicides.

5. Aminocyclopyrachlor - Wikipedia

   en.wikipedia.org/wiki/Aminocyclopyrachlor

   Aminocyclopyrachlor belongs to the pyrimidine carboxylic acid chemical family and mimics auxin which is a growth-regulating hormone in dicots including broadleaf terrestrial plants. [4] This causes undifferentiated cell division and elongation, with resulting appearance characteristic of auxin herbicide damage such as leaf twisting and curling ...

6. Chlorsulfuron - Wikipedia

   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 ...

7. Mesotrione - Wikipedia

   en.wikipedia.org/wiki/Mesotrione

   The triketone herbicides were found to be effective on a wide range of commercially-important weed species and to have both pre- and post-emergence activity. [9] Mesotrione was chosen for development (by Zeneca Agrochemicals under the code number ZA1296) because it controls a wide range of broad-leaved weeds that compete with maize and can also suppress some annual grass weeds that may be ...
