Product Information

Cedar aphid ( Cedrobium laportei): A small aphid (1.5-2mm) long and greyish-brown with a paler mid-dorsal stripe running from the head end. It feeds on cedars including Cedrus atlantica, C. deodora and C. libani.Dense colonies can occur at the bases of the leaves during May and June, this can result in the affected leaves being shed. This aphid excretes large quantities of honeydew and sooty mould frequently develops,both on the tree and on the ground underneath. It should be said that my infestation was very small compared to many others and contained with Diatomaceous Earth. Very important to catch these little shits early and you may have a chance. Where possible tolerate populations of aphids,they form an important part ofmany food chains and can be part of a healthy garden ecosystem The RHS believes that avoiding pests, diseases and weeds by good practice in cultivation methods, cultivar selection, garden hygiene and encouraging or introducing natural enemies, should be the first line of control. If chemical controls are used, they should be used only in a minimal and highly targeted manner. Little can be done to deal with aphids on tall trees as treatment is only likely to be successful if the entire plant is sprayed

Further information on the biology of fruit aphids is available from Influential points at the links below Alternatively, you could try using organic (chemical-free) sprays to get rid of aphids. You can spray these directly on the insects and this activity will only need to be repeated for a short time. Due to thisinsects rapid reproductive rate and the widespread occurrence of pesticide-resistant strains, biological control often gives better results than insecticides on greenhouse plants. Non-pesticidecontrolEach species of conifer aphid has a restricted host range and specific symptoms. Some of the conifer aphids frequently encountered in gardens are listed below.

Some insects feed on other insects. However, it is important to distinguish the beneficial insects from the insects and pests that can damage your plants.Fungus gnats are also very fond of stored compost, especially if it is freshly sterilised or contains animal-derived fertilisers. Keep all your spare compost bags tightly closed. Even better, buy new compost as you need it and avoid storing it altogether. Loam-based John Innes composts tend to be less attractive to fungus gnats than soil-less composts. Little can be done to deal with aphids on tall trees as treatment is only likely to be successful if the entire plant is sprayed.It is difficult to penetrate dense conifer hedges with sufficient thoroughness to prevent conifer aphids causing damage.To prevent damage it may be necessary to spray the trees as soon as signs of aphidsare seen. With most species this will be in late spring or early summer. For the green spruce aphid, however, it is late August or September, with a further treatment on a mild dry day in early February. 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 Another great home remedy to kill greenflies is diatomaceous earth. It will dehydrate them to death. For the recipe, get some mineral oil, fresh garlic, a teaspoon of liquid dish soap, and 2 cups of water.

While the eggs are not an immediate threat, as soon as they hatch, the new aphids will start feeding on your plants. 15. Get Rid of Ants Organic pesticides such as plant oils (e.g. Vitax Plant Guard Pest & Disease Control, Bug Clear Fruit & Veg Ultra, Vitax Rose Guard) have a largely physical mode of action and can be effective against aphids. These pesticides have a very short persistence. Plant oil and fatty acid products are less likely to affect larger insects such as ladybird adults

What are Greenfly?

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. Encourage their natural enemies of hoverflies, lacewings and ladybirds. Plants which these beneficial insects love include catnip, clover, dill, mint, oregano and yarrow. Some ants protect aphids. Therefore, you might want to focus on getting rid of ants if you see a lot of them in your garden. 16. Onion Spray The RHS believes that avoiding pests, diseases and weeds by good practice in cultivation methods, cultivar selection, garden hygiene and encouraging or introducing natural enemies, should be the first line of control. If chemical controls are used, they should be used only in a minimal and highly targeted manner.
