DIRECTIONS FOR USE
IMPORTANT: This leaflet is approved as part of the Product Label. All instructions on this leaflet and on the label should be read carefully in order to obtain successful results from the use of this product.

RESTRICTIONS AND WARNINGS
This product is dangerous to honeybees and bumblebees. It must not be applied to plants in flower or plants that are being actively visited by honeybees or bumblebees.
The best available application technique, which minimises off-target drift should be used to reduce effects on non-target insects or other arthropods. Consult processor before use on crops grown for processing, or for use in cider production.

PESTS CONTROLLED
Envidor is a ketoenol insecticide with a mode of action as a lipid synthesis inhibitor.
Fruit tree red spider mite (Panonychus ulmi)
Two-spotted spider mite (Tetranychus urticae)
Apple and pear rust mites (Aculus schlechtendali, Epitrimerus pyri)†
Pear sucker (Cacopsylla pyricola)
Mussel scale (Lepidosaphes ulmi) ††
For optimum efficacy application early in the pest development cycle is necessary. Young larval stages are most susceptible.

† Limited data indicates that Envidor can provide good control of rust mites. Applications should be timed to coincide with the beginning of conditions that favour the pest (typically shortly after flowering) to ensure that eggs and young larval stages are the principal targets. Alternatively, application in summer against a mixed population of eggs, larvae and adult mites can be carried out but efficacy may be reduced.
†† Limited data indicates that Envidor is effective against mussel scales when applied during the mobile ‘crawler’ phase of the pest in late spring/ early summer (typically late May). Field experience has indicated that about 1-2 weeks after blossom is the optimal application timing on apples.

CROP SPECIFIC INFORMATION
Rate: Apply Envidor at 0.6 litre per hectare where trees are large (3 metre or greater foliar canopy height).
Where tree height and or canopy density is reduced, the dose (and water volume) should be adjusted in accordance with an appropriate dose adjustment scheme, for example PACE. Consult your specialist advisor for further information. Further information on the PACE scheme is available from HDC, or see the HDC leaflet available also at CRD’s website.

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.

Apples and pears, to control fruit tree red spider mite (Panonychus ulmi). In orchards where populations of fruit tree red spider mite winter eggs are above threshold numbers and where populations of predatory mites are inadequate apply the product in spring when 10% of the mite larvae have emerged from their winter eggs, or apply immediately after flowering should this coincide with the flowering period. Alternatively, application in summer against a mixed population of summer eggs, larvae and adult mitescan be carried out but efficacy may be reduced (see statement regarding
optimal efficacy in PESTS CONTROLLED section).
Apples and pears, to control rust mites (Aculus schlechtendali, Epitrimerus pyri). Applications should be timed to coincide with the beginning of conditions that favour the pest (typically shortly after flowering) to ensure that eggs and young larval stages are the principal targets. Alternatively, application in summer against a mixed population of eggs, larvae and adult mites can be carried out but efficacy may be reduced. (see statement regarding optimal efficacy in PESTS CONTROLLED section)
 Apples and pears, to control two-spotted spider mite (Tetranychus urticae). Apply the product as soon as infestation is observed.
Pears, to control pear sucker (Cacopsylla pyricola). Apply the product when the eggs are about to hatch (when they are yelloworange in colour). Envidor is effective on early larval stages but not on the adult form.
High water volumes are recommended for this pest to ensure thorough coverage.
Apples and pears, to control Mussel scales (Lepidosaphes ulmi). Limited data indicates that Envidor is effective against mussel scales when applied during the mobile ‘crawler’ phase of the pest in late spring/early summer (typically late May). Field experience has indicated that about 1-2 weeks after blossom is the optimal application timing.

PESTICIDE RESISTANCE MANAGEMENT STRATEGY
Total reliance on one pesticide will hasten the development of resistance; pesticides of different chemical types or alternative control measures should be included in a planned programme. The compatibility of Envidor with Integrated Pest Management programmes has not been established and safety cannot be assumed. Hazardous to non-target arthropods (predatory mites) if applied repeatedly. Avoid unnecessary exposure.
Alternating insecticides with different modes of action is a recognised anti-resistance strategy. To further minimise the likelihood of less susceptible pest strains arising, Envidor 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.
No more than 1 application of a lipid syntheis inhibitor (e.g. spirodiclofen, spiromesifen) should be made on apples and pears.
Monitoring should be conducted to detect early signs of resistance. If signs of reduced efficacy become evident, follow-up treatments should not be carried out with an active ingredient of the same chemical class.

Mixing and Spraying
Thoroughly shake the pack before use.
Add the required quantity of Envidor 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 tank is completely empty. Spray immediately after mixing. On emptying the container, rinse container thoroughly by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of container safely.
Water volumes:
500 litres/ha up to 1,500 litres/ha. Water volume can be adjusted to suit height of crop. It is important to ensure full coverage of the crop and pest for optimum control. For control of Pear sucker water volumes of at least 800 L/ha are recommended.
Spray Quality: MEDIUM/FINE (as defined by BCPC).
After application, completely drain spray equipment. Thoroughly rinse sprayer and flush the hoses, boom and nozzles with clean water. Dispose of waste rinse water safely.
