Pre-sowing stage 

  • Deep ploughing to reduce the population of insect pest and nematodes.
  • Synchronised sowing.

  • Foliar spray with Mancozeb 1.125 -1.5 kg a.i/ha in 750 lit water for dry root rot.
  • Rogue out diseased infected plants.

Vegetative stage 

  • Collection and destruction of larvae.
  • Use light traps for monitoring of lepidopteran pests.
  • For bacterial blight and leaf spot apply foliar spray of streptocycline (500 ppm)
  • For seedling blight and alternaria leaf spot, spray 0.2% mancozeb or carbendazim 0.05%.
  • For powdery mildew, spray 0.2% sulphur.

Flowering stage

  • Clip the galls, pick and burn the shed buds.
  • Rogue out the phyllody affected plants.
