Product scienceHow It Works: Mode of Action

Ojika works by disrupting the internal "food factory" of the weed. It is absorbed through the roots and leaves, moving rapidly to the growing tips.

  1. Absorption: The herbicide is taken up by the weed's roots from the soil solution.
  2. Enzyme Block: It inhibits the ALS enzyme, which is responsible for creating essential amino acids (Valine, Leucine, Isoleucine).
  3. Starvation & Death: Without these proteins, cell division stops immediately. The weed turns yellow, stunts, and dies within 7-14 days.

Note: Rice plants naturally detoxify this chemical, which is why your crop stays healthy.
