- Chilo infuscatellus (crambidae) or early shoot borer
- Number of feeding punctures near the base of shoot. Rotten portion of straw colored
dead heart emits offensive odour. It can be pulled out eastly.
- Earthing up during early stage.
– Trash mulching
– Trichogramma Chilonis
Soil application of Gammas HCH emulsion @ 1 kg a.i./ha over the cane sets in
famous at the time of planting Granulosis Virus can also be used
2) Top borer:
- Scirphophaga excerptalis (Pryalidae)
- Midrib tunnelling. Shot – holes on axial bud growth leaves, dead heart and can be
pulled out easily and given bunchy top appearance, Acrial root formation.
- Avoiding of frequent irrigation
- Carbofuran @ 1 kg a.i./ha synchronizing with brood emergence
- Trichogramma japonicum
- Pre-pupal parasitoid Isotima Javensis
Resistant var: COJ67, CO 1007
3) Internode borer:
- Chilo sacchaviphagus indicus (crambidac)
- Attack starts from 4th months onwards. Internodes constricted and shortened with
many bore holes: fresh bore holes with wet frass, stunted growth. Major pests in
peninsular India. Hardening of internodes.
- Detrashing at 5.7 & 9th months
T- chilonis @ 3.5 cc/ha/fortnight from 4th month until a month before harvest.
- (Crambidae) Acigone steniellea
- Two phases: Gegarious phase – feed on first internode from to & may larvae enter
into the core through single hole.
- Solitary phase – dispersed to other came by silhen treads.
5) White grub: Holotrichia consanguinea: H. Serrata. (Meloionthidae Anomula
- Drying of crops : Yellowing & nibbling of leaves: roots eaten away.
- Netarhizium onisopliae
- Pudding & crop rotation
- Popillae milky disease
- Odentotermes spp: Microtermes obesi
- Older leaves dry up first & cane falls down if disturbed.
Filled with moist soil inside the papery rind.
- 7) Sugarcane scale: Melanaspis glomerate: (diaspridiadae)
- Grayish block appearance of stem.
- Reduced yield, juice quality of Jaggery production
Detrashing & Trash burning.
8) Leaf hopper:
- Pyrilla perpusilla (Lophopidae) Yellowish white spots on leaves; sooty mould on later stages.
- Externel parasitoid: Epiricarlia melanoleuca (Ephpyropidae)
- Green muscardine fungus: Aceria sacchari (Eriophyidae)
- Forming a circular Ereneum gall in the inner side of the leaf sheath
