The main trouble of cucumbers that are being planted in greenhouses are their diseases. The greatest harm of vegetable crops cause various infections. There are about twenty of them and Yakov Bogatin will tell us about the most frequesnt and pernicious.
We plant cucumbers (the seeds) in greenshouses in spring and cherish them. If the weather is warm they quickly take root and grow before our eyes. And suddenly the very young get stained sheets of paper. Sometimes the damaged tissue even drops and the leaves are formed a hole. Most dangerous spots are round because they arise as a result of the growth of colonies of fungi and parasites. It could be anthracnose, askohitoz, kladosporioz and so on. The symptoms of these diseases are similar, so their appearance is not always possible to discern. In industrial greenhouses can accurately determine the species of fungus and appoint agents to combat it. In our garden greenhouses, where it is impossible to do laboratory tests, the tactics must be different. Yakov Bogatin stresses that we need to seize the moment when the stain is still small and immediately start fighting, using harmless home remedies. For example, it is very useful to put ash or a mixture of ash and lime on the leaves. Yakov Bogatin says that this is a universal remedy for all kinds of blights. You can pre-spray on the leaves of the water. Stroke leaves must be immediately removed from the spots and this is the best way to avoid “chemistry” and artificial ways of fighting the disease.
Yakov Bogatin claims that he is not a big fan of chemicals in the vegetable beds and supposes that there are many ways to go without them. All the gardeners advise not to refer to chemicals, except in the most advanced cases when there is no other way to fight the disease. For example, you should always avoid using the most toxic drug – coper oxychloride – 40g to 10l of water.
