CanolaCAP®

Adult parasitic wasps emerge from the capsule and mate. Fertilised females will then lay their eggs inside aphids, causing the host to swell, harden, and form a characteristic ‘mummy’. The developing wasp kills the aphid and later emerges as an adult. These subsequent generations provide ongoing in-field suppression, with the first mummies typically visible 2–3 weeks after release.

Application Timing

• Results from large-scale trials show that CanolaCAP® is most effective when well-timed with initial aphid detection and early population development. While we cannot yet guarantee complete suppression, the existing data indicates that a well-timed parasitoid release is likely to provide significant reductions in aphid pressure and reduce the need for chemical insecticides.
• Start monitoring weekly at 4-leaf to early budding, focusing on the underside of lower leaves and terminal flowering spikes. Aphids typically first appear along crop edges.
• Timing of release usually coincides with 6-leaf stage.

Application Rate

Current guideline is 1 – 2 capsules per ha. Research to determine the optimum rate is ongoing. In some cases, multiple releases may be required to provide adequate suppression, particularly if pests are persistent or you have multiple reinfestations.

Application Method

• CanolaCAP® capsules are released across fields using a light aircraft equipped with a purpose-built hopper, ensuring quick and even distribution through precision placement technology.
• We have a network of approved aerial operators and light aircraft fitted with capsule-spreading technology.
