Two-Spotted Spider Mite (Tetranychus urticae) – all life stages
How It Works
Phytoseiulus persimilis is a specialist predator that targets spider mites exclusively. It feeds by piercing the mites with its mouthparts and extracting their internal fluids. While all mobile stages of persimilis feed on spider mites, they prefer eggs and immature stages. The larvae do not feed.
SPIDEX VITAL PLUS is delivered in slow-release sachets designed to provide a continuous, natural release of predatory mites over a two-week period. This steady introduction helps establish a persistent population in your crop.
Note: Phytoseiulus persimilis can only survive in the presence of two-spotted spider mites.
Suggested Application Rate
2.5–1 sachet per m² if plants are touching and have formed a canopy.
1 sachet per plant if the leaves are not touching
Rates depend on crop type and pest pressure.
