Nearby will be evidence of their slime trials. They are particularly fond of succulent seedlings, which when left unprotected, can be totally destroyed in a single night. Unlike some controls, Nemaslug continues to work well during wet weather – exactly when you need protection against slugs! The calcium contained in Grazers is absorbed through plant leaves and stems into plant cells. It doesn’t kill slugs and snails but makes plant tissues distasteful so they will seek other food sources. It takes a little while for the calcium to be absorbed and moved through the plant, so if you are transplanting vulnerable young plants from the greenhouse to their outdoor positions, it’s a good idea to treat them with Grazers for a few days prior to doing so. Price wise, Grazers is a relatively economic option, but it obviously requires more labour than putting down wool pellets. However, it’s better suited to large areas of crops or ornamentals. A note on gastropod grazing habits

All of these products are based on ferric (iron) phosphate which is bound to a cereal-flour based bait. Iron phosphate affects the metabolism of calcium in the gut of slugs and snails causing them to stop feeding and die within three to six days. Any uneaten pellets will slowly break down releasing phosphate and iron which will be taken up by plants as nutrients. Effect on earthworms One application of Nemaslug provides 300,000 nematodes for every square metre of soil, giving around six weeks control of slugs. Apply Nemaslug to moist soil. The soil temperature should be 5ºC (40ºF) or over (this is when plants start to grow). Nematodes are capable of surviving the odd frost; so don't worry if the temperature falls after you have applied Nemaslug. Metaldehyde based slug pellets are reported not to be effective below 7ºC. The soil temperature should be 5ºC (40ºF) or over (this is also when plants start to grow). Nematodes are capable of surviving the odd frost; so don't worry if the temperature falls after you have applied Nemaslug. Metaldehyde based slug pellets are reported not to be effective below 7ºC.Nemaslug is easy to apply and does not leave any unsightly residues. The majority of the slugs will die underground, so don't expect to see dead slugs lying around.

Nemaslug should be applied to soils that are at least 5°C. They will survive the odd frost, but applying to hard frozen ground, or prior to a long cold spell will render Nemaslug ineffective. A soil thermometer is a great investment. Til dem af jer, der har have, kan vi allerede nu fortælle jer, at det er ulovligt at sprede salt for at bekæmpe ukrudt, ligesom man ikke selv må formulere og blande et produkt, der kan bekæmpe bladlus. Der findes dog omkring tyve husholdningskemikalier, der er godkendt og tilladt til privat brug, hvoraf brændenældeekstrakt, fruktose, solsikkeolie og eddike er blandt de mest almindelige. Slugs breed all year with two overlapping generations, the peak egg laying is Mar-Apr and Sept-Oct. Applying Nemaslug every six weeks is the best way to keep slugs at bay throughout the growing season. Nemaslug is an effective alternative to chemicals. It is safe to use and harmless to children, pets, birds and wildlife. This will enable the ground and foliage to dry out before foraging molluscs come out at night. Be vigilant during wet weather

De nematoder, der anvendes til bekæmpelse af snegle, har det videnskabelige artsnavn Phasmarhabditis hermaphrodita. Disse nematoder er inficeret med en hurtigtvirkende bakterie kaldet Moraxella osloensis, som kan inficere og dræbe en snegl i løbet af tre dage. If you are after a pellet pesticide to target slug infestations take a look at Advanced Slug Killeror Sluxx.

Jorden skal have et konstant fugtighedsniveau i ca. 2-3 uger efter, at nematoderne er blevet udvandet. The 'Miracle-Gro Hose End Feeder' has been tested and approved for applying the Nematodes listed below by Nematodes Direct and can also be used for applying liquid feed to plants and lawns. From 1 April 2022 it is now illegal to sell and use metaldehyde slug pellets. So, whether you like it or not, this particular weapon can no longer be part of your armoury against the gardener’s number one enemy. British gardeners have been using some 650 billion slug pellets per year – and there is no doubt about it – they worked. Sadly, they worked rather too well. Only a small amount of metaldehyde is needed to poison or kill non-target animals and as the pellets included a bait, every animal which occupies your garden – birds, frogs, toads, newts, hedgehogs, slow worms, mice, even your pets – was at risk.Nemaslug uses the nematode Phasmarhabditis hermaphrodita. One application of Nemaslug provides 300,000 nematodes for every square metre of soil, giving at least six weeks control of slugs. This is generally enough time for seedlings and bedding plants to get well established. One application of Nemaslug provides 300,000 nematodes for every square metre of soil, giving at least six weeks control of slugs. This is generally enough time for seedlings and bedding plants to get well established. Nemaslug is best applied early in the growing season, but you can use this biological control when your soil temperature is consistently above 5C (41F). Only apply this product when you’re certain that your soil temperature will be between 5C (41F) and 30C (86F) for the following two weeks, at least. These nematodes are killed by extremes in both hot and cold temperatures.

Nemaslug controls all common species of small to medium sized slugs (up to 8 cm or 2.5-3 inches). It comes in two convenient sizes to treat small gardens and larger gardens or allotments. Nematoder er en relativ ny metode til at bekæmpe snegle, i hvert fald i Danmark. I Storbritannien har man kunnet købe nematoder i en lang årrække. Denne specielle art af nematoder, kaldet nemaslug, anvendes primært til bekæmpelse af almindelige snegle, selv om der er undersøgelser, der viser, at de også virker mod unge dræbersnegle. Question: Can I eat produce that has been treated with slug nematodes? Yes, just wash your fruit and vegetables in the normal way. Being ugly, slimy and homeless, slugs have few fans, and seem to come in for the most blame. Meanwhile the snail, with its ingenious and pretty armour, its shy ‘peak a boo’ behaviour and the fact that the shell provides a convenient and dry hand hold for curious humans, has a slighter cuter reputation. However, of the 30 plus species of slugs in Britain, only 4 are really garden pests feeding off living plant material, the remainder prefer munching on dead organic matter. If you have a limey soil, point the finger of blame at snails instead. They prefer calcareous soils which provide the necessary calcium to build their shells. Not so effective on heavy soils To make sure the nematodes are adequately watered in, treat the same area again for a further 8 minutes if treating a vegetable patch or 16Once the nematodes are applied the slugs stop feeding after a few days and die within a week. For total control apply every 6 weeks. Start your slug control early and apply at least a week before planting to ensure your garden is safe from slugs. One suggestion I have come across on the internet is to ‘deliberately attract slugs’ to an area of your garden away from your target plants and then to go out and collect them at night. Gardeners World suggests “using something they’re attracted to – old veg leaves, dried cat food, bread rolls, oats or bran”. To me, this sounds like a very good way of attracting rats as well as molluscs and given that rats have a considerable speed advantage, I suspect that both slugs, snails and the gardener are likely to end up disappointed by the results. The nematodes come complete with instructions and can be applied using a watering can or nematode applicator. You just apply to moist soil when the soil temperature is above 5ºC (41ºF) and ensure the soil does not dry out for at least two weeks after applying nematodes. Nematodes are capable of surviving the odd frost; so don't worry if the temperature falls after you have applied the nematodes.
