Neudorff Nematodes Vine Weevil killer

5 million nematodes for Vine Weevil-free plants. 

WINNER OF THE 2018 GARDEN INDUSTRY MANUFACTURERS ASSOCIATION AWARDS. The judges said.....'a product that says great things about ecological gardening and really opens up the market for consumers'.

Naturally occurring Heterorhabditis bacteriophora nematodes will kill vine weevil grubs in the soil, preventing them from killing the roots of your precious plants. All without the use of pesticides! Each pack will treat 12m2 or up to 210 pots, so this is a highly economic method of controlling the devastating vine weevil grubs.

Nematodes are microscopic roundworms that can be found in almost every ecosystem. Some species are predatory and can be used in horticulture to control soil-borne pests. They enter vine weevil larvae and inject it with bacteria, causing its death. The nematodes will then eat the dead body, multiplying within it, and immediately search out new vine weevil larvae to act as their host again. Once the host is killed, the life cycle of the nematodes will also stop, leaving no trace in the compost.

Nematodes thrive in soil at temperatures between 10-30C, and can start working immediately, though it may take time for the full results to be seen. Applications are best from April to September. Unlike most nematodes that need refrigeration for storage, Neudorff nematodes are placed in a state of 'cryptobiosis' which prevents them from moving or using oxygen, and they can remain alive in this state for up to 6 months.

If you see the tell-tale signs of vine-weevil notching on the edge of leaves, apply nematodes to very moist soil around the rootball, in the morning or dusk when temperatures are cooler. Evening applications are recommended as UV light kills nematodes. Applications on rainy, overcast days encourages optimal penetration into the soil.

Simply drop the 'tea-bag' sachet into tepid water and stir for 1-3 minutes until the water becomes cloudy, and the nematodes have diffused out. Do not over-shake as this will cause the sachet to break, and the carrier material can block the sprayer or watering can rose. Drench the roots of your plants, so that the nematodes can seek out and kill any weevils. 

Store in cool conditions. Child and pet safe. Always use in accordance with label instructions. Use before expiry date.
