Product Information

Nematodes are best used straight away, but they can be stored in the fridge and used within 12 days. The main downside with using nematodes to control vine-weevil larvae outdoors, or in an unheated greenhouse, is that they are very sensitive to temperature. This control works best if the soil remains above 12°C for at least 14 days after use. This makes August and September the most effective application period, though you can apply in April or May before the adult weevils emerge from their pupae if it is warm enough. By October it’s generally too cold to deal with them outdoors. Suppliers of biological controls for vine weevil

Don’t bother attempting control of aphids on trees as they are considered part of thebiodiversity trees support and natural enemies will normally reduce numbers Should you remove aphids? Tolerate aphids where possible. It is usual to have some in a healthy, balanced garden.They are a vital food source for a wide range of wildlife in the garden The female weevils lay their eggs in the compost or soil among host plants. As a rule, this happens in August and September, though a lot depends on the weather during the previous winter and spring. In a mild year, egg-laying could start in early summer. Each female is capable of laying 1000 or more eggs. These eggs are less than 1mm across, white at first, later turning brown. They are difficult to see and much smaller than the granules of controlled-release fertiliser found in container-grown plants, which are often mistaken for insect eggs. Plant invigorators that combinenutrientsto stimulate plant growth with surfactants or fatty acids also have a physical mode of action against aphids (e.g. Spot-On Bug Control, Growing Success Bug Stop, SB Plant Invigorator and Doff Universal Bug Control). These products contain some synthetic ingredients and so are not considered organic Half fill a pressurised sprayer with clean water before adding the required quantity of product. Add the reminder of the water and mix thoroughly before use. Mix and use immediately.Many aphids, especially those on fruits and vegetables, go through an annual cycle that involves two or more host plants. The plant on which overwintering eggs are laid is oftena tree or shrub. In the spring, the eggs hatch and the aphids feed on the young foliage. By early summer, the foliage has grown older and tougher, this combined with increasing temperatures and day-length induces winged forms of the aphid that migrate to the summer host plant. This is usually a non-woody plant with soft, succulent foliage. Some aphids, however, spend the whole year on one type of plant, although they may be active for only part of the year. Adult weevils feed on leaves, chewing irregular notches in the margins. Their mouthparts are incapable of making holes in the middle of the leaves. (This sort of damage is likely to be caused by caterpillars or slugs.) Vine weevils are especially fond of camellias, euonymus and rhododendrons, though they will also feed on other shrubs and tough herbaceous plants like bergenias. Where you cannot tolerate aphids, manage them using the information above as your first course of action. Biological controlfor the larvae is available as microscopic insect pathogenic nematodes. Several species and combinations are available ( Steinernema kraussei, Heterorhabditis megidis, H. bacteriophora and S. feltiae). They are availablefrom suppliers of biological controls and as sachet formulations available from some retail outlets. They are suitable for use in containers and in the open ground.For best results apply in August or early September when the soil temperature or potting mediais warm enough for the nematodes to be effective ( Steinernema species 5-20ºC/41-68ºF Heterorhabditus species 12-20ºC/ 54-68ºF) and before the vine weevil grubs have grown large enough to cause serious damage

Always follow the instructions on the products. For edible plants, make sure the food plant is listed on the label and follow instructions on maximum number of applications, spray interval and harvest interval. It is usually possible to see aphid colonies with the naked eye, many species colonise shoot tips, flower buds and the underside of younger leaves If only a few pots are affected, try sifting the grubs out by hand. Squash any you find before repotting the plants in fresh compost and putting the rest in the bin. What about barriers for vine weevil?

Vine weevil / RHS Gardening

Weevils are a group of several families of beetles in thesuperfamily Curculionoidea, there are more than 500 species in the UK. All feed on plant material, mostly live plants but a few feed on dry seeds (grain weevils) or rotting wood. Most do not cause noticeable damage to garden plants and several species are uncommon.Vine weevil is classified in a subfamily of the known as the broad nosed weevils (Entiminae), so called because the of the broad snout (rostrum) these weevils have. There are over 100 species in this subfamily in Britain. More information on broad nosed weevils from UK Beetles. Hydroponic systems are a modern and innovative approach to indoor gardening, eliminating the need for soil. Instead, you grow plants in a nutrient-rich water solution,[…] The adults are active between the end of June and October. In daylight you might spot the odd one walking across the patio or on the wall of the house. If you go out at night with a torch there’s a good chance you will see them feeding on the foliage.

The RHS recommends that you don't use pesticides.Most pesticides (including organic types) reduce biodiversity, including natural enemies, impact soil health and have wider adverse environmental effects. Where to Use: Ideal for use on flowers, roses, ornamental plants grown in pots and hanging baskets outdoors and in conservatories. We thought it was the right time of year to talk about how worms transform organic matter into nutrient-rich castings. Plagron Mega Worm Castings consist[…]
