Integrated Weed Management

For Pure crop of Sugarcane

  1. Line weeding once along the crop row and spade digging of ridges have to be done on 30, 60 and 90 DAP, or
  2. Spray Atrazine 2 kg or Oxyflurofen 750 ml/ha mixed in 600 liters of water as pre emergence herbicide on the 3rd day of planting, using deflector or fan type nozzle fitted with knapsack sprayer, or
  3. The pre emergence application of atrazine @ 1.0 kg a.i./ ha on 3 DAP followed by post emergence directed application of glyphosate @ 1.0 lit/ha on 45 DAP with hood+ one hand weeding on 90 DAP, or
  4. If pre-emergence spray is not carried out, go in for post-emergence spray of Grammaxone litre + 2,4-D sodium salt 2.5 kg/ha in 600 liter of water, 20 DAP, or
  5. If the parasitic weed striga is a problem, post-emergence application of 2,4-D sodium salt @ 2.0 kg/ha in 500 litre of water/ha may be done. 2, 4-D spraying should be avoided when neighbouring crop is cotton or okra. Apply 20% urea also for the control of striga as direct spray, or
  6. Pre- plant application of glyphosate at 2.0 kg/ha along with 2% ammonium sulphate at 21 days before planting of sugarcane followed by post emergence direct spraying of glyphosate at 2.0 kg/ha along with 2% ammonium sulphate with a special hood on 30 DAP to suppress the nut sedges (Cyperus rotandus).
  7. If herbicide is not applied, work the junior-hoe along the ridges on 25, 55 and 85 days after planting for removal of weeds and proper stirring. Remove the weeds along the furrows with hand hoe. Otherwise operate power tiller fitted with tynes for inter-cultivation.
  8. Control of creeper weeds post emergence directed application of fernoxone (2, 4 –D sodium salt) @ 2 gm + 10 gm of urea per liter of water may be sprayed over the creeper weeds.
