Integrated Pest Management for sugarcane woolly Aphid

Cultural and Mechanical control

  • Paired/ wider row planting - In the endemic pockets, paired or wider row planting of sugarcane is beneficial in implementing the plant protection practices.
  • Seed selection- Care should be taken in selecting seed material from pest free areas and uninfected fields. Burn the sugarcane leaves, remaining after the sett preparation in infested area. .
  • Balanced use of chemical fertilizers – Apply the recommended chemical fertilizers. Excess use of nitrogenous fertilizes leads to increase the pest problem.
  • Intercropping – Intercrops viz. cowpea, green gram, black gram, ladies finger, cabbage etc. needs to be taken in sugarcane, as predators may survive on a common aphids in absence of sugarcane woolly aphid.
  • Earthing up - Timely earthing up avoids lodging of cane and crop is exposed to more sunlight.
  • Weed control - Keep the crop weed free and clean the bunds and fields as pest survive on some of the weeds Viz. Sorghum halepens, Coix lacrima jobi, Miscanthus sinensis and Cynodon dactylon (hariyali) which is alternate hosts of the pest.
  • Transport of cane - Avoid the transport of infested leaves or cane to pest free field/area.
  • Destruction of infested leaves - Clipping and disposing of affected leaves, when the pest problem is noticed initially in patches.

Biological control

  • Release of predator -Release of predator, Dipha aphidivora larvae or cocoons @ 1000 / hectare or Micromus larvae/cocoons @ 2500/ hectare or Syrhid fly larvae or cocoons @ 1000 / hectare Release the predators only on 1000 sq. ft. area in one field and it will take care for one hectare area within three months. During heavy incidence, apply the recommended dose of chemical insecticides to reduce the pest population and then release the predator after 15 days. Avoid use of chemical insecticides if, predators are noticed in infested fields.
  • Biopesticide - Spraying of biopesticide during May to August, when infestation of aphid is less and predator development is poor, will help to avoid the use of toxic insecticides.
  • Erection of minimum six shade nets each on one R area at each factory level for the multiplication of predators and its supply.
