Rimsulfuron

Trade Names: Elim (available only in Battalion and Galaxy co-packs), Prism

Group 2

Site of Action: Inhibitors of acetolactate synthase (ALS) and also called acetohydroxyacid synthase (AHAS)

Symptoms
Following POST emergent application:

  • Within an hour the inhibition of ALS enzyme leads to a rapid cessation of cell division and plant growth
  • Within 1- 2 weeks symptoms become visible
  • Meristematic regions are the first to experience chlorosis and necrosis followed by general foliar chlorosis and necrosis
  • The most recently emerged leaf at time of application will show a characteristic Group 2 “flash” (a chlorotic band running perpendicular across the middle of the leaf)

Uptake and Translocation

  • Following foliar application rimsulfuron is rapidly absorbed through the leaves
  • Translocated in both xylem and phloem

Persistence

  • Rimsulfuron rapidly degrades in soil
  • There are no rotational restrictions
