Mesotrione is a synthetic mimic of the natural herbicide leptospermone. It was developed and first marketed by Syngenta in 2001.  Mesotrione is a systemic pre-emergence and post-emergence systemic herbicide of broad-leafed weeds.  In pre-treatment the compound is absorbed by the seedling as it emerges, in post-treatment the compound is absorbed through the leaves. Mesotrione has a strong residual effect.  Mesotrione acts by inhibiting the plant enzyme 4-hydrophenylpyruvate dioxygenase which is necessary for the biosynthesis of cartenoids. Without cartenoids chlorophyll is no longer protected from sunlight and breaks down, therefore preventing photosynthesis and resulting in the death of the target weeds.  Mestrione is effective in controlling annual broadleaf weeds such as water hemp, velvet leaf, common ragweed, redroot/ smooth pigweed, wild mustard, common lambsquaters as well as crabgrass.  Mstrione has been shown to been effective on many species that have become round-up resistant. Mestrione is registered for use on maize/corn for foraging and grain.  Mesotrione is also used in conjunction with terbuthylazine to control pre-emergnce grasses as well as broad-leaf dicotylendous weeds.
