How it works

How it works

Mode of action

Predatory mites multiply in the sachet and disperse into the crop over a period of several weeks. They pierce the prey with their sucking mouthparts and suck out the contents.


Mobile stages are beige, droplet-shaped mites. Eggs are oblong and transparent white. Adults are about 0.5 mm in size. Predatory mites are usually found on the lower surface of the leaves, often in the corner of the main vein and lateral veins. It is not possible to distinguish Amblyseius andersoni in the field from Amblyseius swirskii, Neoseiulus californicus, Neoseiulus cucumeris, Transeius montdorensis or Amblydromalus limonicus.

Directions for use

Directions for use


Hang sachets in sheltered locations in the crop, not exposed to direct sunlight. Sachets already have an exit hole. Hold sachets by the cardboard strip at the top, to avoid damaging the predatory mites.


The dosage of Anso-Mite Plus depends on climate, crop and pest density and should always be adjusted to the particular situation. Start introduction preventively or as soon as the first pests are detected in the crop. Use at least 4,000 sachets per ha and hang them evenly spaced in the crop. Release should be repeated after 4 weeks if the pest is not controlled. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
