Weed Management in Maize

Chemical Control:

Maize crop is sensitive to weed competition during early crop growth period for first 3 – 4 weeks. 2-3 days after maize sowing (before germination), pre-emergence application of Atrazine 1.5-2 kg. /ha. mixed in 500 lts. of water (2.5-3 g. /lt.) is recommended. This prevents the emergence of weeds up to 30 days after sowing.  Precautions to be taken are:

  1. Use adequate amount of water.
  2. Ensure proper moisture in soil. To check, take a fistful of soil and press. It should form a soft lump.
  3. Use flat fan nozzle.
  4. Spray uniformly walking backwards.
  5. Spray in evening.
