Common questions
- How do I recognise Sugarcane borer on sugarcane?
- Caterpillars tunnel inside the stalk, leaving entry holes plugged with frass; 'dead-heart' in young cane, weakened stalks that snap, and red rot entering the bore holes. Tiny egg masses sit on the leaves.
- Do I have to report Sugarcane borer?
- No. Sugarcane borer is not a notifiable organism, so there is nothing to report to an authority. Treat it as a normal garden problem.
- How is Sugarcane borer treated?
- Mainly with biological and cultural measures — removing affected material, changing the conditions that favour it, and treating with agents approved in your country. The exact steps and their timing depend on the plant, the season and where you live: Dr. Phyto works them out in a free diagnosis.
