The APVMA confirmed that both the Spinosad and Spinetoram labels cover Mango shoot looper as the labels state Geometrid loopers. The directions for use (on both labels) read “loopers” for use in tropical and sub-tropical fruits (inedible peel).
Only spray if mango shoot loopers (Perixera cf. illepidaria) are present. Inspect flowers, immature fruit and new shoots for damage and caterpillars stripping leaves and/or flower panicles. Small larvae are difficult to see. To monitor, vigorously shake flower panicles or new flush into a tray or bucket.
The APVMA also advised that the minor use permit PER14743 Trichlorfon / Custard apple, Lychee, Mango, Persimmon would cover the Mango shoot looper as the permit is approved for control of “loopers (multiple species)”. However, some growers have reported failures with Trichlorfon on mango shoot looper. It is likely mango shoot looper may have developed some resistance to this chemical.
Growers have reported widespread failures of synthetic pyrethroids (e.g. beta-cyfluthrin) on mango shoot looper, these pesticides are not registered for use on mango shoot looper and should be avoided as they may exacerbate the problem.
Applying for emergency use permits and registering chemicals is a priority for the affected plant industries, Hort Innovation, DAF and NT DITT.
An emergency use permit has been issued by the Australian Pesticides and Veterinary Medicines Authority (APVMA) for Methoxyfenozide (Prodigy Insecticide). See permit details here.
