Envidor (active substance: spirodiclofen) is our novel acaricide with activity on pear sucker and scales. Envidor has a unique mode of action which combines long-lasting protection with anthocorid safety for effective integrated pest management.

Why use Envidor

Mites, mussel scale and pear sucker can be especially difficult to control in orchards and once established destroy fruit quality. Mites are notoriously challenging to control and the choice of effective products is limited. Envidor has a unique mode of action and shows safety to anthocorids – making it an essential component in pear sucker control programmes.

Main advantages

  • Broad-spectrum acaricide
  • Unique mode of action
  • Excellent long-lasting protection
  • Activity on pear sucker and scales
  • IPM compatible with anthocorid safety

Getting the best from Envidor

To get the best from Envidor when using on mites, apply early in the pest development cycle – young larval stages are the most susceptible. For fruit tree red spider mite, apply in the spring when ten per cent of the mite larvae have emerged from their winter eggs. For rust mite, apply shortly after flowering to ensure that eggs and young larval stages are the principal targets. For two-spotted spider mite, apply as soon as infestation is observed.

To get the best against pear sucker it is critical to apply at the correct pest stage. Optimal results are achieved by applying close to the point of egg hatch (yellow egg stage). No application should be made during flowering of the crop. Typical timing for pests on top fruit is soon after flowering. Good crop coverage is essential. High water volumes of at least 800 L/ha are strongly recommended against pear sucker and mussel scale.

Important things to remember

  • 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

Using Envidor as part of a programme

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 one to two weeks after blossom is the optimal application timing on apples.
