RUNNER™ is a benzoylhydrazine MAC (Moulting Accelerating Compound) insecticide for the control of tortrix (Adoxophyes orana), winter moth (Operophtera brumata) and codling moth (Cydia pomonella) larvae in apples and pears. Methoxyfenozide mimics the natural moulting hormone 20-hydroxyecdysone, causing complete cessation of feeding and premature moulting within hours of the moth pest larvae ingesting treated plant tissue. The larvae subsequently die within a few days as a result of dehydration and starvation.

 

Because RUNNER is harmful to caterpillars of pest species, it is likely that it will also be harmful to caterpillars of some non-target butterfly and moth species. To minimise the risk posed by RUNNER to these non-target species, users should minimise off-target drift into natural habitats (e.g. hedgerows and meadows) using the best available application techniques.

 

 

Alternating insecticides with different modes of action is a recognised anti resistance strategy. Methoxyfenozide, a member of the MAC (Moulting Accelerating Compound) class of compounds which have a different mode of action from other top fruit insecticides (including chitin biosynthesis inhibitors and juvenile hormones), is ideally suited for this practice. To further minimise the likelihood of less susceptible pest strains arising, RUNNER should always be applied at the full recommended rate of use and in sufficient water volume to achieve the required spray penetration into the crop and uniform coverage necessary for optimal pest control.

 

Apply RUNNER at 0.6 litre per hectare where trees are large (3 metre or greater foliar canopy height). The rate of RUNNER should be reduced in proportion to foliar canopy height to a minimum of 0.4 litre per hectare where trees are small (up to 2 metre foliar canopy height). This is equivalent to 0.04% spray (40 millilitres in 100 litres of water) using a water volume of 1500 litres per hectare for large trees or a water volume of 1000 litres per hectare for small trees.

 

Apply RUNNER in 150 to 1500 litres of water per hectare (with air assistance). It is important, particularly when spraying post-blossom, to achieve full penetration of the leaf canopy and uniform coverage of the foliage and blossoms or fruitlets.

 

RUNNER must be applied early, when the Lepidopterous larvae are small, for maximum effectiveness according to the life cycles of the individual pests species. The latest timing of application for RUNNER is 14 days before harvest.

 

A spray should be applied pre-blossom from early green cluster or during blossom when the first signs of active larvae, which spin themselves into the young leaves and blossom after overwintering, are seen. In the summer (about June), another treatment can be carried out if there are larvae of the summer generation present (Tortrix only).

 

A post-blossom spray should be applied on the basis of pest monitoring. The optimal application timing is from early to peak egg deposition. Codling Moth will usually require a series of follow-up treatments and RUNNER may be used for up to two of these, - see ‘Number of Sprays’ section.

 

 

Effective larva control in top fruit usually requires several sprays of insecticide per year and RUNNER may be used for up to a maximum of three of these sprays. No more than two sprays of RUNNER should be applied consecutively (see ‘Pesticide Resistance Management Strategy’).

 

 

The maximum residue level for methoxyfenozide in apple and pear of 0.5 mg/kg must not be exceeded.

 

Thoroughly shake the pack before use.

 Add the required quantity of RUNNER to the half-filled spray tank with the agitation system in operation, and fill to the required level. Continue agitation at all times during spraying and stoppages until the tank is completely empty. Spray immediately after mixing.
