Amblyseius Swirskii – 100x Waterproof Slow Release Sachets (SWIR2)

Swirski-Mite Plus contains the predatory mite Amblyseius swirskii, a highly effective natural enemy of thrips, whitefly, and tarsonemid mites, targeting young larvae of various thrips species and eggs and larvae of whitefly. This polyphagous predator establishes rapidly in a wide range of protected cropping systems, including glasshouses and polytunnels, and is a warm active temperature predator with an optimum range of 20–32 °C. A. swirskii moves very rapidly and when applied preventatively or at the first signs of pest presence, the species maintains stable populations by feeding on pollen and small arthropods, ensuring continuous pest suppression throughout the crop cycle. With its continuous-release sachets, Swirski-Mite Plus ensures long-lasting protection and consistent predator establishment over a number of weeks.

Pack size: 100 sachets each containing 250 Amblyseius swirskii predatory mites and prey mites. Presentation: Sachets in cardboard box. Carrier: Bran.

Technical Comments

Combined use: Do not combine with other generalist predatory mites. Can be combined with Orius spp. and whitefly parasitoids.

Activity / Control

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. Environmental conditions: Amblyseius swirskii is most effective at temperatures between 20 and 32°C (68 and 90°F). It is not effective at temperatures below 18°C (64°F). A. swirskii is sensitive to relative humidity below 60%.

Application Method

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 Storage time after receipt: Apply as soon as possible after receipt. If necessary, the product can be stored for 1-2 days. Storage temperature: 12-14°C/54-57°F. Storage conditions: In the dark, provide ventilation to prevent CO2 accumulation.

Application Rate

The dosage of Swirski-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 pest mites 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.
