Control of Sugarcane Pyrilla
These insects are very agile, jumping from one leaf to another. In the area where the infestation is much more, louder noise is noticed. Both nymphs and adults suck the sap from the leaves. Honeydew like substance is secreted from their bodies and falls on the leaves. As a result, black sooty mould is formed on sugarcane leaves, which affects the cane's photosynthetic activity, and thus drastically yield loss is observed.
Below mentioned are important management practices to control sugarcane pyrilla:
• Collect & destroy the bunch of eggs laid by the adults
• Spray Metarhizium anisopliae, a fungual-based powder @ 40 g per 10 lit of water
• Release of Epiricania melanoleuca, parasite @ 1 lakh parasites (250 egg masses) or 2000 pupae per hectare
• Do not spray any chemical insecticides in the parasites released area/fields
• If parasite activity are not observed, pyrilla infestation will be more in the field, then spray Chlorpyriphos 20 EC @ 20 ml or monocrotophos 36 EC @ 10 ml per 10 lit of water
