Beschreibung
Imazamox is registered throughout the world for use
in leguminous crops, including soybeans, alfalfa, and
edible beans, as well as in imidazolinone-resistant
crops (9). A nonionic surfactant or oil adjuvant is
required for maximum activity. Imazamox
is much more active when applied post-emergent to the
weeds compared with pre-emergence application (9). One
difference between imazamox and other imidazolinones is
the much shorter interval needed before sensitive follow
crops can be planted. This difference is due to the more
rapid degradation of imazamox in the soil compared with
other imidazolinones.
Chemische Eigenschaften
Off-White Solid
Verwenden
Imazamox is an imidazolinone based acetolactate synthase inhibitor that is utilized as a herbicide for weed control.
Pharmakologie
Imazamox kills plants by inhibiting acetolactate synthase
(ALS) (I50 = 1 μM), which is the first common enzyme in
the biosynthesis of the branched chain amino acids, valine,
leucine, and isoleucine. Imazamox is rapidly absorbed
through the leaves of plants. Once it enters the plant,
imazamox rapidly translocates to the growing points and
growth ceases within 1 day after herbicide application,
followed by chlorosis and then by necrosis of the growing
points. Total plant death will occur within 2 to 3 weeks
after treatment.
Stoffwechsel
Plant Metabolism. The selectivity of imazamox is due to
differential rates and routes of metabolism in tolerant
crops versus susceptible weeds (10). The primary
metabolic route is hydroxylation followed by conjugation
to glucose. In imidazolinone-resistant crops, the primary
mechanism of selectivity is due to an altered acetolactate
synthase that is not inhibited by imazamox (11).
Animal Metabolism. Metabolism studies in the rat
showed that imazamox is rapidly excreted in the urine.
There was no accumulation of imazamox or any of its
derivatives in the liver, kidney, muscle, fat, or blood (9).
