Mode of Action

HRAC2
HRAC4

ALS Inhibitor + Synthetic Auxin

Celsius combines two modes of action: thiencarbazone-methyl and iodosulfuron-methyl-sodium both inhibit ALS (HRAC 2), blocking branched-chain amino acid synthesis, while dicamba mimics synthetic auxin activity (HRAC 4), disrupting cell elongation and growth. The dual mode of action broadens the weed spectrum and reduces resistance selection pressure.

Resistance Management

Low resistance risk due to dual mode of action (HRAC 2 + 4). The combination reduces the probability of resistance development versus single-mode products. Continue to rotate with non-ALS herbicides as part of an integrated program.
