BugClear Ultra Vine Weevil Killer Concentrate 480ML

Product Information

Physical barriers on top of the soil or compost also work very well. Add a 2cm (0.75in) deep layer of sharp grit or gritty gravel on top of the compost or around the base of the plant to prevent the adults from laying eggs; the egg-laying structure is irritated by the scratchy feel. Ensure you drench the soil thoroughly. Sprays can’t move through the soil like nematodes. The insecticide then kills the vine weevil larvae via a chemical process. Leaf damage is visibly obvious as the adult weevils nibble at the edge of leaves, causing irregular-shaped notches in the leaf margins, during the summer months. However, root damage caused by the young larvae is not always immediately obvious. The plump, creamy white legless grubs have light brown heads and are up to 10mm long. They are likely to be found among the roots, where they feed voraciously. Vine weevil can feedon a wide range of plants, both indoors and outdoors, but can be especially damaging to plants grown in containers.It is a verywidespread andcommon insect. The adult weevils eat leavesduring spring and summer, but it is the grubs that can cause the most damage over autumn and winter when they feed on plant roots. This damage can resultin wilting andplant death. This is a symptom that the vine weevil larvae are eating your roots, reducing the plant’s ability to take up water and nutrients.

It’s highly unlikely you’ll be able to see the vine weevil eggs in compost or soil as they’re so tiny - less than 1mm. Although vine weevil is one of the most troublesome of all garden pests the gardener now has some very effective methods of control options. In the first instance, look for signs of damage to leaves, which might indicate the presence of vine weevil. Plants that do not appear to be growing as well as they should, are sure signs that the vine weevil grubs may be active below ground. Vine Weevils are particularly fond of plants in pots or containers, where the roots are restricted. If containers are large enough then place one trap within the confines of the container’s soil surface. A trap containing nematodes ( Steinernema carpocapsae), isavailable for controlling adult vine weevil. The traps should be placed on the ground below plants damaged by the weevils during the summer. The adults enter the trap during the day and are infected by the nematodesLarge items are sent via a standard 48L (48 hour large) service. Large items take from 2 working days to arrive. Vine weevil is one plant insect pest that most gardeners live in fear of. And it is a pest to worry about. Suddenly, otherwise healthy-looking plants collapse and die thanks to the root-eating, soil-borne grubs. More serious is the damage can becaused by the soil-dwelling larvae, which are plump, white, legless grubs up to 10mm (about 3/8in)long with pale brown heads. These eat the roots of a wide range of plants andcan bore into tubers of cyclamen and begonia, and into stem bases of cacti and succulents. They can kill woody plants by gnawing away the outer tissues of the larger roots and stem bases. Most plant losses occur during September to March, when the grubs are becoming fully grown. They’re the best treatment for vine weevil, since it’s a safe, natural treatment with no chemicals.

Nematodes work for six weeks, but give up to four months since they prevent the larvae from hatching into adults and causing another lifecycle. A full list includes: Arisaema, Aster, Astilbe, Azalea, Begonia, Bergenia, Camellia, Cyclamen, Echinacea, Epimedium, Euonymus, Fuchsia, Heuchera, Hosta, Hydrangea, Busy Lizzie, Kalmia, Lily, Peony, Phlox, Primula, Polyanthus, Raspberry, Rhododendron, Saxifrages, Sedum, Strawberry, Syringa, Yew and Wisteria. Vine weevil damage The white C-shaped larvae then emerge into the soil from June and start to eat the roots of the plant. They can feed until October. All vine weevil adults are female, and each one can lay hundreds to thousands of eggs from April to September; the main egg-laying periods are April and August/September.

Vine weevil control

Vine weevil is a very widespread insect in Britain. Gardeners with vine weevil should keep up their guard because stopping control measures after the apparent disappearance of the weevil can allow numbers to build up again. If you spot golden-brown or clear egg-like objects in the soil or compost then they're NOT vine weevil eggs. Vine weevil eggs are brown and tiny and you'd need a hand lens to see them. Clear spheres are usually slug or snail eggs and the golden-brown ones are actually controlled-release fertiliser! After use, theNematop® Weevil-Stop trap can be disposed of or burned just like any other waste wood material. Use the measure provided to mix 60ml of BugClear Ultra Vine Weevil Killer with 1 litre of water in a watering can or mixing vessel.

Plants growing in pots and containers, outdoors or under cover, are most likely to be severely damaged by vine weevil grubs. Plants growing in the open ground are less likely to be damaged, althoughheavy infestations ofgrubscanoccur on strawberries, Primula, polyanthus, Sedum ,Heuchera and young yew plants. The Nematop® Weevil-Stop trap can be used at the same time as Nemasys Vine Weevil Killer for a two pronged assault on the pests, which should prove to be twice as effective. However, the nematodes within the special gel need a higher temperature before they become active. It is therefore recommended the soil temperature be at least 12°C, and so May would be the ideal time to position the wooden traps. Have you any other top tips you think are worth a mention? Please leave a comment below and let us know.... Vine weevils are a devastating plant pest. Suddenly otherwise healthy-looking plants wilt and collapse and no amount of watering will help them recover. The reason? Vine weevil grubs have eaten all the roots.This ingenious method is proving very popular amongst many gardeners, who are reporting very positive results. The wooden traps need to be placed gel side down on wet or damp soil, so ensure the soil area below plants is well watered if dry. Position the traps, gel side downwards, near affected plants allowing one board for each 10 square metres. Keep the areas damp during spells of dry weather. The nematodes will remain active for at least 6 weeks. The larvae survive through the winter but stop feeding. They hibernate around the roots over winter, and then form pupae in April. Vine weevil (Otiorhynchus sulcataus) is a common UK garden pest affecting over 200 plants and fruits like strawberries. It’s active from Spring to Autumn. Natural nematodes applied to the soil offer the best treatment. Some adult beetles also survive by finding sufficient places to shelter over winter, but again stop feeding until April.
