Chemical management

  • Discourage the indiscriminate use of insecticides, particularly synthetic pyrethroids
  • Use of proper insecticides that are comparatively safer to natural enemies such as phosalone at the correct dosage and alternating different groups of insecticides for each round of spray
  • Avoid combination of insecticides as tank mix
  • Adopt proper delivery system using spraying equipments like hand compression sprayer, knapsack sprayer and mist blower to ensure proper coverage with required quantity of spray fluid and avoid ULV applications
  • Proper mixing and preparation of spray fluid for each filling of spray fluid tank
  • At early stages of square formation apply one of the following insecticides

Acephate 75% SP 780 g/ha or Flubendiamide 39.35% SC 100-125 ml/ha or Azadirachtin 0.03% EC 500 ml/ha or Indoxacarb 14.5% SC 500 ml/ha or Carbaryl 10% DP 25 kg/ha or Lufenuron 5.4% EC 600 ml/ha or Chlorantraniliprole 18.5% SC 150 ml/ha or Novaluron 10% EC 1000 ml/ha or Chlorpyriphos 20% EC 1250ml/ha or Diflubenzuron 25% WP 300 g/ha or Profenofos 50% EC 1750-2500 ml/ha or Emamectin benzoate 5% SG 190-220 g/ha or Pyridalyl10% EC 1500-2000 ml/ha or Fipronil 5% SC 2000 ml/ha or Spinosad 45.0% SC 165-220 ml/ha or Flubendiamide 20% WG 250 g/ha or Thiodicarb 75% WP 1000 g/ha.

  •       During bolling and maturation stage, apply any one of the following insecticides (1000 lit.  of spray fluid/ha):

                           - Quinalphos 25 EC 2.0 l/ha

                                  - Carbaryl 50 WP 2.5 kg/ha

                                  - Pyraclofos 50 EC 1.5 l/ha

  • Dicofol, methyl demeton, monocrotophos and phosalone are comparatively safer to Chrysoperla larva recording low egg mortality
