Product Information

Inclusion of a pesticide product does not indicate a recommendation or endorsement by RHS Gardening Advice. It is a list of products currently available to the home gardener Encourage the natural enemies of aphids in your garden, such as ladybirds, ground beetles, hoverflies, parasitoid wasps and earwigs. In spring, aphid populations increase before the natural enemies are active in sufficient numbers – so if you wait a while, they’ll often give the control Gooseberry aphid: Summer host =willow herbs ( Epilobium spp.). Leaves fruitinMay-June. Can remain on gooseberry throughout summer

Follow label instructions when using pesticides. On 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. 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. Where possible tolerate populations of aphids, they form an important part ofmany food chains and can be part of a healthy garden ecosystem Each species of conifer aphid has a restricted host range and specific symptoms. Some of the conifer aphids frequently encountered in gardens are listed below. Each female can lay more than 200 eggs. Males are rare and reproduction takes place without the need for fertilization. The eggs hatch into small crawler scale-like nymphs which crawl around for a while before they begin feeding and become immobile.The nymphs are a flat, oval shape, whitish-green in colour, and just over 1mm in length when fully developed.The final nymphal stage is called a pupa and the adult whitefly eventually emerges through a slit in the dorsal surface. The length of the life cycle varies according to the temperature. At 10ºC (50ºF) the life cycle takes several months, but can be completed in about three weeks at 21ºC (70ºF).The insect can remain active during the winter in an unheated greenhouse, provided suitable host plants are present. Glasshouse whitefly does not usually survive winter out of doors.Attracting all types of insects includes their larvae too – especially in the case of ladybirds as they are particularly effective at greenfly control. Although ladybird larvae may look unpleasant, it is not to be confused with something that will harm your plant. It is, in fact, a good sign so if you see it, leave it. How many greenflies are cause for concern?

In glasshouses it is possible to use glasshouse fumigants. Glasshouse should be sealed and instructions on the product label must be followed. An organic fumigant based on garlic is available as Pelsis Pest-Stop Biofume Greenhouse Fumigator and can be used when crop plants are present. Products based on the synthetic pyrethroid permethrin are available as DeadFast Greenhouse Smoke Generator, DeadFast Greenhouse Smoke Fumigator and Vitax Greenhouse Fumigator When the population is high, if there are predators about, or the greenfly are ready to move to different plants, then winged greenfly develop. Once settled on their new hosts, these lose their wings and give rise to wingless greenfly again. They continue to produce more young, including some males, then, as day length shortens and temperatures fall in autumn, they mate and produce eggs that will overwinter. Otherwise called greenflies, aphids feed on plant sap. They also produce honeydew, which can attract ants and other insects [ 1].But, helpless we are not, as the rose specialists at David Austin Roses highlight. We asked their Technical Manager, Michael Marriott, to share his top tips on how to get rid of greenfly in our gardens. What are greenfly? Unless you are allergic to tomatoes, this recipe isn’t dangerous for humans or plants. Directly spray the leaves and undersides of plants in your garden to kill the harmful plant lice. Garlic Oil Spray As Ben Franklin said, “An ounce of prevention is worth a pound of cure.” He was talking about fire safety, but it is often applied to health safety. Or in this case, garden safety. There are a few things you can do to prevent invasive insects such as aphids or spider mites from infesting your garden. Attract Favorable Bugs

Plant invigorators combine nutrients to stimulate plant growth with surfactants or fatty acids that have a physical mode of action against aphids (e.g. Ecofective Bug Control, Growing Success Bug Stop, Rose Clear 3 in 1 Action SB Plant Invigorator and Westland Resolva Natural Power Bug & Mildew). These products contain some synthetic ingredients and so are not considered organic Fungus gnats are attracted to composts that are high in organic matter, such as peat-based composts, decaying plant tissue and compost that is kept constantly damp, such as pots containing insectivorous plants. They feed mainly on plants, but are also partial to any form of decaying organic matter. How can I deter fungus gnats? Lady beetles and lacewings are two insects that feed on aphids. Introducing them to your garden is a natural selection way to combating their infestations while keeping the beneficial bugs safe from chemical pesticides.In essence, the only role they play in their whole lifecycle is to extract plant sap, from plants. Imagine them as illegal tenants in a flat you rent out. They take advantage of the shelter you provide, they drink all your supplies, use your facilities and don’t even bother to pay you the rent due. Combine one tablespoon of neem oil suitable for garden use, one tablespoon of liquid soap, and a gallon of water. Finally, pour this homemade greenfly spray into a bottle and spray your plants. 2.
