The decision on whether or not to grant a 120-day authorisation had been passed to Defra, claims the SA, with ministers left to to determine if the need by the organic sector outweighed the potential environmental concerns. Items will be dispatched same day if purchased before 17:30 Mon-Friday otherwise the next working day. By its presence on the surface of the plant tissue, the fungicide works by interfering with the cellular system of fungal organisms and prevents their germination. A copper-based blight fungicide has been given emergency approval following lobbying of Defra minsters by the Soil Association to retain its use.

It is also very effective for control of a number of common fungus and bacterial blights including both early and late blight in tomato and potatoes, box blight, laurel shot hole disease, leaf spots of vegetable crops, rusts on onions, leeks and ornamentals, peach leaf curl, rose black spot, ornamental leaf spot including Olive Peacock Spot, bacterial canker on cherry and plum and apple canker / apple scab / brown rot, citrus collar rot. Copper 50 WP is a fungicide in the form of a powder for the preparation of a water suspension with a surface effect for preventive use in protection against diseases, in amateur cultivation of low-growing fruit trees also vegetable plants in allotments and home gardens. Products approved in the UK are assigned a registration number, printed on the pack – MAPP numbers for pesticides for use on plants and HSE numbers for household products.We hope it will provide certified organic farmers with the confidence to grow less-known varieties, as well making it easier in future for other farmers to grow potatoes without using chemicals. For best results, start spraying before the disease is visible or when it is first noticed on the plant. It's hard to tell without a very high quality microscope but the resulting solution looks different - I suspect that the particles in the powder are bigger. Fungal diseases can be a real problem for gardeners, especially when the weather is warmer and wetter than usual.

A foliar spray with preventative and curative properties, it is suitable for use on a wide range of crops. The maximum dose of copper substances from all sources, including non-plant protection uses, must not exceed 4kg copper/ha per annum. however, the formulation of copper oxychloride is not set (you have more then three different formulas for copper oxychloride) and therefore the inconsistency means it is used less this days.

There are many formulations of copper products on the market, differing widely in the amount of copper, active ingredients, rate of application, and other factors. I wasn't able to save it, those who think it only distorts a few leaves, have no idea how damaging this disease can be.
