Muster: ethametsulfuron-methyl

Trade Names	Muster
Formulation	DF
Guaranteed active concentration	75%
Groups	2
Ontario Schedule	5
Winter Storage	C

Crop and/or Non-Crop Registrations	Spring canola
Sensitive Weeds	Wild mustard
Uptake and Translocation	Following foliar application, is rapidly absorbed and translocated in both xylem and phloem.
Basis of Selectivity	Inhibition of acetolactate synthase in susceptible plants leads to a rapid cessation of cell division and growth. Tolerant species rapidly convert ethametsulfuron-methyl to non-phytotoxic metabolites.
Application Methods	Postemergence
Residual Activity	Rapid soil microbial degradation.
Unique Characteristics	A non-ionic surfactant must be added. Typical symptoms of plant death (leaf crinkling, curling, chlorosis) occur 5-10 days after application depending on growing conditions.
