NemaFence® Green - fast acting sustainable control for chafer & vine weevil grubs
How does NemaFence® Green control white grubs?
- Parasitic nematodes for effective control – Heterorhabditis bacteriophora controls garden chafer and 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 – NemaFence® Green has no harmful side effects on beneficial insects and fits perfectly into an integrated pest management strategy.
When should you apply NemaFence® Green?
- Start at the first signs of infestation – apply as soon as the first larvae are detected.
- Apply during the active larval stage – the recommended application period is April to September. For garden chafer, the ideal timing is August to September. For black vine weevil, apply as soon as larvae are present.
- Start early in potting substrates – in pots and containers, early applications after sowing or planting are recommended.
How do you apply NemaFence® Green?
- Apply the nematodes with water – dissolve the entire contents of the package in water and keep the suspension well agitated during application.
- Keep the soil moist – moisten the soil before application if necessary and irrigate immediately afterwards to move the nematodes into the soil. Keep the soil moist for at least two weeks.
- Avoid direct sunlight – apply preferably in the evening or under cloudy conditions for optimum performance.
Under which conditions should you use NemaFence® Green?
- Optimum performance between 14°C and 30°C (57°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 flood irrigation systems.
- Ideal for integrated pest management – thanks to its rapid action, natural reproduction and excellent compatibility with beneficial insects, NemaFence® Green is a reliable biological solution for controlling white grubs.
