Target Weeds

Katyayani MSM effectively controls several problematic broadleaf weeds, including:

  • Chenopodium album (Lambs quarters) 
  • Melilotus indica (Sweet Clover) 
  • Lathyrus aphaca (Yellow Vetchling) 
  • Anagallis arvensis (Scarlet Pimpernel) 
  • Cyperus rotundus (Purple Nutsedge) 
  • Amaranthus viridis (Green Amaranth) 
  • And other similar broadleaf weeds 

These weeds are common in cereal and cash crop fields and can significantly reduce productivity if not controlled.

Suitable Crops

Katyayani MSM is recommended for use in:

  • Wheat 
  • Rice 
  • Sugarcane 

It ensures effective weed management without harming the crop when used at recommended doses.

Mode of Action

Metsulfuron methyl works by inhibiting a key enzyme in plants called Acetolactate Synthase (ALS).

  • Blocks synthesis of essential amino acids (valine, leucine, isoleucine) 
  • Stops cell division and plant growth 
  • Causes gradual wilting and death of weeds 

This systemic action ensures that weeds stop growing soon after application and are eliminated over time.
