CAS 81777 89 1 clomazone herbicide
Clomazone is a oxazolidinone that is 1,2-oxazolidin-3-one substituted by a 2-chlorobenzyl group at position 2 and two methyl groups at position 4.
It has a role as an environmental contaminant, a xenobiotic, a herbicide, an agrochemical and a carotenoid biosynthesis inhibitor.
It is a member of monochlorobenzenes and an oxazolidinone.
Clomazone is a broad spectrum herbicide used for control of annual grasses and broadleaf weeds in cotton, peas, pumpkins, soybeans, sweet
potatoes, tobacco, winter squash and fallow wheat fields.
It can be applied early preplant, preemergent or preplant-incorporated depending on the crop, geographical area and timing.
Because clomazone is an inhibitor of plant pigments, users must exercise caution to avoid drift or vapors
which may cause bleaching damage to non-target foliage.
Clomazone is available in emulsifiable concentrate formulations.
Clomazone is an agricultural herbicide, The molecule consists of a 2-chlorobenzyl group bound to a N-O heterocycle called isoxazolidinone.
It is a white solid. Clomazone I used for broadleaf weed control in several crops, including soybeans, peas, maize, oilseed rape, sugar cane,
cassava, pumpkins and tobacco. It may be applied pre-emergence of incorporated before planting the crop.
Clomazone is relatively volatile (vapor pressure is 19.2 mPa) and vapors induce striking visual symptoms on non-target sensitive plants.
Clomazone undergoes biological degradation, exhibiting a soil half life of one to four months. Adsorption of the herbicide to soil solids slows
degradation and volatilization. Encapsulation helps reduce volatility and therefore reduces off-target damage to sensitive plants. Clomazone
suppresses the biosynthesis of chlorophyll and other plant pigments.
