Crop monitoring from July onwards is key to making effective decisions for controlling diamondback moth.
- Diamondback moth (DBM) can be a serious pest
of canola and is found in all grain-growing regions.
- DBM outbreaks have become more frequent and
severe in some regions, particularly in seasons with mild winters.
- The key to DBM control is to monitor crops
from mid-July onwards.
- Resistance to commonly used insecticides
is a major concern.
- Use thresholds to guide spray decisions
and rotate insecticide groups between years.
- High-risk situations may require two sprays applied
within seven days to control DBM.
- Spray application withholding periods before harvest
or windrowing are the same, and must be observed.
