Larvanem can be used for the biological control of weevil larvae, beetles and caterpillars in a wide range of crops.

How it works 

The nematodes penetrate the pest and release a symbiotic bacteria into the pest’s body cavity. These bacteria convert the host tissue into a food source, through which the nematodes feed, develop and reproduce within the host. This kills the infestation within a few hours or days of infection.

Preparation

• Remove the sachets from the box and keep at room temperature for 30 minutes
• Empty the contents of the sachets into a bucket containing at least 2 litres of water per sachet (water temperature: 15-20°C)
• Shake well and soak for 5 minutes
• Remix and pour the contents of the bucket into a half-filled spray tank (unless tank-mixed with a compatible product)
• The tank mix should be continuously agitated (e.g. by a recirculation pump).
• Fill the spray tank with the required amount of water
• If tank-mixed with a compatible product, add Larvanem last into a fully filled tank
• Apply directly after spraying. Preparation of the solution

It can be applied using a watering can, compressed air sprayer, irrigation system, backpack sprayer or motorized sprayer. To prevent blockages, all filters should be removed, especially if they are smaller than 0.3 mm (50 mesh).

The dose of Larvanem is usually 250,000 to 500,000 nematodes per m² (2.5 to 5 billion/ha).

The timing and frequency depend on the pest species and the crop environment (relative humidity, soil moisture and temperature).
