Spical-Plus Predatory Mites – 100 Slow-Release Sachets for Spider Mite Control
Spical-Plus provides preventative biological spider mite control using the beneficial predatory mite Neoseiulus californicus. Supplied as 100 slow-release sachets, it introduces predators gradually onto plants, helping manage pest populations before they become established.
The sachets act as small breeding units, allowing predatory mites to multiply before moving onto surrounding foliage over several weeks. This makes Spical-Plus a practical choice for ongoing protection within a suitable Integrated Pest Management (IPM) programme.
Important Use Restriction: Only apply within permanently protected structures with full enclosure, in accordance with applicable licence conditions. Not for outdoor release. Do not use on tomato crops.
Key Features & Benefits
- 100 slow-release sachets: Convenient hanging format for distribution throughout the crop.
- Beneficial predatory mites: Contains Neoseiulus californicus.
- Preventative protection: Suitable for introduction before an infestation develops or when spider mites are first detected.
- Gradual release: Predators breed inside the sachets and disperse over several weeks.
- Warm-condition tolerance: More tolerant of higher temperatures and lower humidity than Phytoseiulus persimilis, within suitable operating conditions.
- IPM application: Supports a coordinated biological pest management programme.
Which Pests Does Spical-Plus Target?
Spical-Plus is used to control two-spotted spider mite (Tetranychus urticae), European red mite (Panonychus ulmi), citrus red mite (Panonychus citri) and other susceptible spider mite species.
Confirm the pest species and crop suitability before choosing a biological treatment.
How Neoseiulus californicus Helps Protect Plants
Neoseiulus californicus, previously known as Amblyseius californicus, actively searches foliage for spider mites. It particularly favours immature stages, including eggs, larvae and nymphs, although adult female predators can feed on all spider mite stages.
It can also survive on alternative food sources, including pollen, when spider mites are scarce. This helps explain its usefulness in preventative programmes and the longer-term management of low pest populations.
For a heavy infestation, seek advice on a combined treatment programme rather than relying on slow-release sachets alone.
Temperature & Humidity Requirements
Neoseiulus californicus performs most effectively between 13°C and 32°C and is sensitive to relative humidity below 60%.
Its greater tolerance of warmer, drier conditions compared with some other predators does not mean it is unaffected by low humidity. Check conditions within the crop before application.
How to Apply Spical-Plus Sachets
- Plan placement: Follow the recommended release rate for your crop and pest pressure.
- Handle carefully: Hold each sachet by its cardboard strip rather than squeezing the contents.
- Hang evenly: Distribute sachets throughout the crop in sheltered positions, away from direct sunlight.
- Leave sachets intact: An exit opening is already provided; do not cut them open or empty the contents.
- Monitor the crop: Check spider mite activity regularly and arrange further releases where needed.
Application Rates & Repeat Releases
Koppert's general guidance is to introduce at least 4,000 sachets per hectare, distributed evenly. The appropriate rate depends on the crop, climate and pest population.
Repeat the introduction after four weeks if the pest is not controlled, following crop-specific advice. Pack size should not be treated as a guaranteed coverage area.
Check the compatibility of any pesticides and their residues before introducing beneficial mites or applying further treatments.
Storage & Handling
Apply as soon as possible after delivery. Spical-Plus contains living organisms and should not be held unnecessarily.
If a short delay is unavoidable, store for 1–2 days at 17–20°C, in darkness with adequate ventilation to prevent carbon dioxide accumulation. Follow the instructions supplied with your order.
