CanolaCAP®

Adult parasitic wasps emerge from the capsule and mate. Fertilised females will then lay their eggs into aphids. A wasp larva will hatch within 2-3 days and feed on the aphid’s insides, eventually causing it to mummify and die. The parasitised aphid, known as a mummy, becomes easy to recognise as it appears bloated and takes on a shiny bronze or gold colour. Once development of the parasitoid is complete, a new adult wasp emerges from the mummy. It will mate and seek out new aphid hosts to parasitise, providing ongoing suppression of aphid populations.

Application Timing

• A preemptive inoculative release coinciding with the first detection of aphids is the most effective way to prevent aphid outbreaks in your crop.
• 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.
• Infestations may be patchy so sample multiple points across the field. Sticky traps are also a helpful monitoring tool to ensure early capsule application.

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.
