Preventive Measures

  •   Use certified seeds or clean seed from a known source free from admixture of weed seeds.
  •   Avoid application of un-decomposed organic manures as it contains viable weed seeds.
  •   Cleaning seeds by dipping in 2% brine solution (salt solution) helps in the selection of high-density seeds and separation of floating weed seeds.
  •   Off-season ploughing after rice harvest reduces weed seed replenishment.
  •   Deep summer ploughing once in three years.
