Avert 25WP is a low cost option for control of porina caterpillar and clover flea in pasture
When used correctly it will prevent significant pasture damage from these pests
Because Avert 25WP only affects organisms that moult, it has relatively low toxicity to humans and other mammals
Avert 25WP has a convenient low use rate of 50g/ha
Application
Avert 25WP can be applied with conventional spraying equipment correctly calibrated to apply the correct rate of Avert 25WP in sufficient water to provide full coverage of the foliage. Do not use strainers finer than 300 microns.
For Porina Caterpillar, Avert 25WP is best applied when the majority of caterpillars are in the late surface dwelling or early tunneling stages, before they have grown to 25mm long. This will usually be 10-12 weeks after peak moth flights. Where peak moth flights occur in spring (October-November), caterpillar tunnels can be found in January-February. Where peak moth flights occur in January – March, caterpillar tunnels can be found in May-July.
For Clover Flea, Avert 25WP is best applied at the first sign of Clover Flea, which is usually in April – May when nymphs emerge from resting eggs. This will reduce the build up of subsequent generations in winter.
For full information on application rates and timings please refer to the product label.
Mode of action
Avert 25WP is an insect growth regulator that disrupts chitin deposition and prevents moulting of porina caterpillar and clover flea of pasture. Avert 25WP is only effective if eaten by target insect larvae. Best results will occur from application to larvae when they are small, growing rapidly and moulting frequently.
