Dead heart in young sugarcane crop with dead hearts emitting an offensive odour is due to the attack of early shoot borer, Chilo infuscatellus.
Release of Sturmiopsis inferens @ 312 gravid females/ha against C. infuscatellus kept the pest under control.
Earthing up operation reduces the attack of early shoot borer, Chilo infuscatellus.
Attack of stem or internode borer, Chilo sacchariphagus indicus results in constriction and shortening of internodes. Affected tissues also become reddened.
Dethrashing is followed for the control of internode borer.
Release of Trichogramma chilonis at 4th and 11th week stage of the crop @ 1,25,000 adults/ha provided effective control of internode borer in sugarcane. .
Dead heart of grownup canes with shot holes in emerging leaves, red tunnels in midrib of leaves and bunchy top due to the growth of side shoots is due to the attack of top shoot borer, Scirpophaga excerptalis (nivella).
Top borer can be controlled by releasing parasitoid, Isotima javensis.
Gurdaspur borer, Bissetia steniellus feeds below the rind in a spiral manner and series of punctures are seen externally.
Yellowing, sooty mould formation in leaves, drying up of top leaves and formation of lateral buds is the symptom of attack of Pyrilla perpusilla in sugarcane.
Release of Epiricania melanoleuca (Lepidoptera) egg masses @ 4-5 lakh and 4000 to 5000 viable cocoons per ha. reduces Pyrilla infestation.
Sugarcane wooly aphid is scientifically known as Ceratovacuna lanigera which is a major outbreak in 2003.
Scientific name of pale headed striped borer is Chilo suppressalis and dark headed stripped borer is C. polychrysa.
Hot water treatment, dipping of sets for 15 minutes in 0.1% malathion 50 EC before planting controls sugarcane scale, Aulacaspis tegalensis.
Damage of mites in sugarcane is characterised by red streak on the leaves and webbing on the
under surface of the leaves.
