Kraussei-System

How does Kraussei-System control black vine weevil larvae?

• Parasitic nematodes for effective control – Steinernema kraussei controls black vine weevil larvae in the soil. The nematodes enter the larvae and kill them within 24 to 48 hours through their symbiotic bacteria.
• Natural and sustainable action – the nematodes reproduce inside the dead host and release new infective juveniles that search for additional larvae.
• Safe for IPM programmes – Kraussei-System has no harmful side effects on beneficial insects and fits perfectly into an integrated pest management strategy.

When should you apply Kraussei-System?

• Start at the first signs of infestation – apply as soon as black vine weevil larvae are detected.
• Apply during the right period – in open field crops, the recommended application periods are March to May and August to October. In strawberries, the ideal period is March to May.
• Start early in potting substrates – in pots and containers, early applications after sowing or planting are recommended.

How do you apply Kraussei-System?

• Apply the nematodes with water – dissolve the entire contents of the package in water and keep the suspension well agitated during application.
• Keep the substrate moist – the soil or substrate should be moist before application and remain moist for at least two weeks afterwards.
• Avoid direct sunlight – apply preferably in the evening or under cloudy conditions for optimum performance.

Under which conditions should you use Kraussei-System?

• Optimum performance between 5°C and 30°C (41°F to 86°F) – keep the soil temperature within this range during application and for at least two weeks afterwards.
• Use suitable application equipment – do not exceed 20 bar spray pressure and never apply through a flood irrigation system.
• Ideal for integrated pest management – thanks to its rapid action and compatibility with beneficial insects, Kraussei-System is a reliable biological solution for controlling black vine weevil larvae.
