Integrated Management of Major Sugarcane Diseases
||Red rot, smut, wilt, leaf scald, ratoon stunting etc.
- Crop debris should be burnt after harvest. Weeds around the
field should be destroyed.
- Irrigate the field if preceding crop was
affected with smut (soil with moisture stress promotes smut incidence).
- Dried or chlorotic clumps should be uprooted. Smut whips
should be cut and burnt.
- GSD affected shoot should be uprooted and discarded. Spray
Dimecron (0.02%) 2-3 times at 15 days interval.
||Red rot, GSD, leaf scald
- Keep keen watch on red rot affected canes. As and when
yellowing or drying of top leaves is seen, confirm red rot by splitting.
Such affected stools should be uprooted and burnt. Bunding should
be done around the field to check flow of water to other fields.
Regular attention should be given on drying of canes.
- On border of
field, GSD affected plants should be looked for. If GSD affected
plants are frequent, Dimecron (0.02%) may be sprayed 2-3 times at 15
- Uproot leaf scald affected canes and discard.
||As and when rust pustules start appearing on leaves, spray Dithane
M-45 or Dithane Z-78 (0.25%) at 15 days intervals 3-4 times.
|Yellow spot, eye spot
||Removal and burning of affected leaves. Spray copper
oxychloride (0.2%) 3-4 times at 15 days interval.
|October to harvesting
- Removal and destruction of smut affected tillers.
harvesting of crop if disease incidence is high.
- Discontinue ratooning if red rot, wilt or smut incidence in high.
- Crop rotation should be followed with suitable crop. Use certified
seed of sugarcane after rotation.
