Product scienceHow It Works: Mode of Action

Rifit works by creating a chemical layer on the soil surface under the paddy water.

  1. Uptake: As weed seeds germinate, their emerging shoots (coleoptiles) absorb the chemical from the treated soil/water interface.
  2. Inhibition: The active ingredient stops the production of VLCFAs (Fatty Acids) needed for cell membrane growth. This prevents the weed cells from dividing.
  3. Elimination: The weed seedling dies before it can surface, while the rice plant (protected by the Safener) grows healthy and unaffected.

Note: Weeds that manage to emerge often show "buggy-whipping" (tightly rolled leaves) and die shortly after.
