Phytoline biological control agent contains the predatory mite, Phytoseiulus persimilis. This well-known predator will eat large numbers of two-spotted mite, Tetranychus urticae. It is a standard treatment in many crops, particularly tomatoes, cucumbers, strawberries and ornamentals.

Key Features

  • Recommended for spider mite control on a wide range of crops.
  • Adults and young stages feed voraciously on adults and eggs of the two spotted spider-mite.
  • Controls spider mites resistant to acaricides.
  • Transparent containers allow growers to observe mites for quality control.

Target Pests

  • Two-spotted spider mite (TSSM)

How It Works

  • Adults and young stages feed voraciously on all two-spotted spider mite life stages.
  • Effective at wide temperature range above 57°F/14°C and can be used outdoors as well.
  • At temperatures over 86°F/30°C, spider mite growth rate will overtake that of Phytoseiulus.
  • Less active at low light levels but will not go into diapause.

Available delivery systems

Available in a range of sizes including:

  • 500ml (16oz) bottle containing 2,000 or 20,000 mites for application over wide areas.
  • 30 ml (1oz) vials containing the same number of mites for treatment of hot spots
  • The hot spot vial comes with a cap designed for dosing specific areas of the crop.
  • Available in vermiculite as the carrier material for use in ornamentals, which is moistened for optimal transit conditions.

Handling & Storage

General instructions for use:

  • Immediately before opening, tap base of the bottle sharply on a solid surface to dislodge mites. from inner surface, and gently roll bottle to distribute them evenly throughout carrier material.
  • Apply mites repeatedly by inverting the bottle over spider-mite-infested-leaves.
  • Each inversion delivers a measured amount of vermiculite.
  • Tap and roll bottle before re-opening it.
  • Leave empty bottle open on infected plants to allow any remaining predators to escape.

16oz/500ml bottle for large areas:

  • Distribute the product over leaves, gently shaking and rotating bottle to give uniform distribution. Vigorous shaking will kill mites.
  • Repeat release and increase the rate in established spider mite colonies until control is achieved.
  • For advice on recommended release rates, consult The Bioline App.

Instructions for use - Vial (for hot spot treatment):

  • Use higher recommended rate range.
  • Open each vial when ready to use in the greenhouse.
  • Leave empty bottle open on infected plants to allow any remaining predators to escape.
  • For advice on recommended release rates, consult The Bioline App.

Storage and transport

  • Keep bottles horizontal and cool until use.
  • Transport and store at 6-10°C /43-50°F.
  • Do not expose to direct sunlight at any time.
