An Expert System for Disorder Diagnosis in Sugarcane Crop


Integrated Management of Major Sugarcane Insect-Pest
(Plant Crop)


Stage Insect-Pest Management
Selection of seed Cane borers, scale, mealy bug and woolly aphid Canes affected with such insect-pests should be discarded.  Canes from woolly aphid infested field should not be used for seed.
Sett treatment Scale, woolly aphid Setts should be dipped in Malathion (0.1%) or Dimethoate (0.08%) for 15 min. before planting.
At planting time Termite, root borer, early shoot borer Chlorpyriphos @ 1 kg a.i./ha to be sprinkled on setts placed in furrows.
From emergence up to May Early shoot borer
  1. Release of Sturmiopsis inferens @ 125 adult females/ha (for coastal region in Tamil Nadu).
  2. Granulosis virus (@ 107-109/ml) spray on foliage (for coastal region in Tamil Nadu and Karnataka).
Thrips Foliar spray of Dimecron (0.03%) or Monocrotophos (0.04%) or Dimethoate (0.04%).
April-June Woolly aphid Intensive survey for locating woolly aphid infestation especially near water source (river, pond. marshy land). Alternative hosts may also be searched.  Such foci of aphid infested plants should be sprayed with insecticide like Metasystox (0.05%) 2-3 times at 15 days interval.
June-July Top borer
  1. Soil application of Carbofuran 3G (1.0 kg a.i.) or Phorate 10G (3.0 kg a.i.)/ha as and when moth of II brood appear.
    In eastern U.P. and Bihar, application should be done in 2nd week of June, while in western U.P., Haryana and Punjab (in case of high sugar varieties) in last week of June.
  2. In tropics, release of laboratory reared Isotima javensis in field.
July to August White grub
  1. After first shower of monsoon, adult beetles should be collected from the nearby trees and killed.  For effective collection, light trap may be used.
  2. When adult (beetles) emerge, soil application with Quinalphos 5G @ 2.5 kg a.i./ha.
Woolly aphid
  1. No insecticide spray against the pest.
  2. Release of predators of woolly aphid, Dipha (Conobathra) aphidivora and Micromus igorotus in infested field where predator activity is absent or low.
July to September Gurdaspur borer, Plassey borer Mechanical removal of infested plants bearing gregarious larval stage through a campaign.
  1. Redistribution of Epiricania melanoleuca cocoon and egg masses from high population bearing fields to low population ones by stapling cocoon.egg bearing leaf pieces on lower side of leaves.
  2. Foliar spray of Metarhizium anisopliae @ 106-107 spores/ml.
  3. Release of adult of Pyrilla infested with M.anisopliae spores @ 250 adults/ha in infested field.
July to October Stalk borer, Internode borer, Gurdaspur borer, root borer
  1. Release of Trichogramma chilonis through Trichocards @ 50,000 parasitised eggs/ha (4 Trichocards/ha) at 10 days interval.
  2. Release of Cotesia flavipes @ 500 mated females/ha at weekly intervals till November.
October to November Stalk borer
  1. Detrashing of leaves at monthly intervals.
  2. Removal of water or late shoots at fortnightly intervals.
  3. Sprayed Monocrotophos @ 0.75 kg a.i./ha on detrashed canes (recommended for ring planted canes).
November to December Stalk borer Spray Beauvaria bassiana @ 107 spores/ml.
Black bug Release of black bug adults infested with Beauvaria bassiana @ 5000 adults/ha.
At harvesting of crop All insect pests
  1. Stubble shaving flush with the ground.
  2. Removal and destruction of water/late shoots.
  3. Burning of crops debris.
Plassey borer Early harvesting of canes latest by February end.
