relatively recent occurrence of grapes in Siberia gardens with good farming practices not conducive to the accumulation of pathogens of this crop.Amateur vineyards did not need chemical protection.
But without supervision imported from other regions and districts vines of different varieties has led to the emergence and spread of dangerous diseases of grapes.The most harmful of these is oidium - fungal disease of grapes, which begin treatment immediately.
Meet oidium, also known as powdery mildew false, he is pepelitsa
first discovered more than half a century ago in England, this vine disease rapidly spread around the world.The varieties that are resistant to mildew, very little in nature.If a young vine (most often at the base of the kidneys) appear white film, which goes on all the escape or has already become yellowish or black (in this case, seems to escape charred, it dries up), be aware that it oidium - the disease of grapes.Treatment with fungicides - a sure way to destroy this attack.Treated plants should immediately upon detection of such a raid.The next stage of the disease: the leaves, usually on the upper side, the fungus appears gray powdery bloom, leaf covered with brown speckles and dries.But the most dangerous - the defeat of grapes, which the parasite can reproduce after their ovaries to mature.Brush priporashivaetsya bold gray bloom, berries covered first speckles, shrivel and dry.If the berries are in the process of maturation, it appears wet rot.The skin on a grape seed cracks and bulges.The berries are low in sugar, maturation occurs.In severe cases oidium grapes unfit for consumption.Another fungus - gray mold, but it affects only the berries, which is typical for this disease of grapes.With photos oidium compare this image with the brush botrytis - the distinction clear.
measures to combat fungal ailments
Oidium - threatening disease of grapes.Treatment of landings at the first sign you can start with the use of colloidal sulfur.It is poorly soluble with water, so spray the drug in the morning practice in calm warm weather after drying the green part of the vine.The sulfur is mixed with the sieved fine wood ash in a ratio of 3: 1.At the first signs of oidium by spraying a solution of potassium permanganate slightly pink in color, with a solution of baking soda with a concentration of 0.5%.But if the already hard rampant the disease of grapes, without fungicide treatment is unlikely to be successful.
for use in amateur vineyards and orchards in order to combat fungal diseases such drugs are allowed to fungicidal component, as the "album", "Abig rush", "Planriz", "Integral".Processing of grapes from diseases carried by these means during the growing season, and should be carried out strictly according to instructions.The most effective drug is "integral" - just a single vineyard spraying and other means necessary to spend 5 to 8 treatments.
