  • Do not spray crops suffering from drought or other stresses.
  • Do not spray wet crops where run-off is likely to occur.
  • Test ornamental plant sensitivity by spraying a small number of plants first.
  • Do not apply in a tank mix with a triazole-containing fungicide when bees are likely to be actively foraging.
  • A minimum interval of 20 days must be observed between applications to eligible crops.
  • Avoid spraying within 5 m of the field boundary to reduce effects on non-target insects or other arthropods.

Active substances


Chemical group: Deltamethrin belongs to the Pyrethroid sub-group of insecticides.

Bio-chemical mode of action: Pyrethroids affect the insects nervous system by keeping sodium channels open.

Mobility: Deltamethrin is a contact and residual insecticide which affects insects following direct contact or when ingested.

Application timing: Deltamethrin is best applied when the insect pest is first observed.

Resistance: Some species of aphid and whitefly are resistant to pyrethroid insecticides. Where resistance occurs repeated treatments are likely to result in lower levels of control. To reduce the risk of resistance use no more than the recommended number of applications on any crop each year. Do not apply the insecticide at a lower rate than is recommended and use as part of an Integrated Pest Management strategy which seeks to utilise non-chemical options for control and to rotate active substances with different modes of action.
