Time is ticking on the use of chlorpyrifos in the banana industry. Last year the Australian Pesticides and Veterinary Medicines Authority (APVMA) released their regulatory decision to cancel all uses of chlorpyrifos in bananas. There was a 12 month ‘phase out’ period to allow use of products already in the supply chain or on farm. Here are some important dates to be aware of.

Important considerations
- Changing to alternative chemicals may not as be as simple as changing chemicals. Especially if changing from dusting to bunch spraying, consider the whole bunch pest management strategy.
- Before use of any chemical: – Confirm the registration status by checking the Australian Pesticides and Veterinary Medicines Authority website portal.apvma.gov.au – Check product label and permit rates.
- Consider resistance management.
- Good bunch spray coverage is important to get effective control of bunch pests.
– Consider which equipment set up to use and how best to achieve good coverage with recommended volumes.
– Staff training is important for calibration and application of pesticides.
– Additional training will be required for farms transitioning from bunch dusting to spraying. - The rate for bell injecting spinetoram, listed in the minor use permit (PER87198), is different to the label rate for bunch spraying with spinetoram.
- When changing from bunch dusting to spraying, consider if other elements of bunch pest and disease management need to be considered, e.g., reducing fungal damage by increasing air flow in bunch covers.
- Regularly calibrate equipment and check application techniques and revisit product label and permit rates.
- Check the storage requirements of chemicals and only mix volumes required for immediate use.
- Always comply with WH&S directions on labels and permits when applying chemicals, including wearing personal protective equipment.
The chemicals that are registered for control of banana rust thrips that target the soil-dwelling pupal stages can be applied by stem injection, stem spray and/or band application (always check label directions). Timing of these applications should be carefully considered and applied ahead of high-pressure periods which can help reduce banana rust thrips pressure.

"Ingrid and I have been visiting growers as they are making changes to their bunch pest management practices. This has led to some good discussions about different options, experiences and things to keep an eye out for. We want to share our learnings from the bunch pest trials we have undertaken, so I encourage growers to give us a call."
