MCPA (2-methyl-4-chlorophenoxyacetic acid) is a widely used phenoxy herbicide introduced in 1945. It selectively controls broad-leaf weeds in pasture and cereal crops. The mode of action of MCPA is as an auxin, which are growth hormones that naturally exist in plants. [2] [3]
Methylene cyclopropyl acetic acid (MCPA) is a compound found in lychee (Litchi chinensis) seeds.[1]The major carbocyclic fatty acid in the seed oils of Litchi chinensis is a cyclopropane fatty acid named Dihydrosterculic acid; these have been found in many plants of the order Malvales (), in up to 60% of seed oil content, depending on the species but also in leaves, roots and shoots.

It is often used in combination with other chemically related herbicides such as 2,4-D, dicamba, and MCPA, which mimic the plant hormone IAA (auxin) and kill most broadleaf weeds by causing uncontrolled growth. The United States Environmental Protection Agency has classified mecoprop as toxicity class III - slightly toxic. [4]

The use of herbicides in US agriculture is mapped by the US Geological Survey. As of 2019, 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]

Invasive species are often grouped by threat levels that vary from county to county from very high impact to remarkable increased growth. The species below are by no means comprehensive and are listed in type order rather than level of threat [1] [2] [3]
