Microbiological protection of plants means processing of crops the medicines made on the basis of useful microorganisms and products of their activity.
Annually thousands of harmful organisms cause to agriculture of our country damage - it is weeds, causative agents of diseases, insects wreckers. Because of them agricultural producers lose from 17 to 40% of a harvest. As use of chemical pesticides for pest control leads to environmental pollution and deterioration of agricultural products, for protection of plants began to use a progressive microbiological method.
What medicines are used for microbiological protection of plants
Apply the medicines created on the basis of microorganisms and products of their metabolism to microbiological protection. In most cases active ingredients of medicines are live viruses, mushrooms and bacteria. Some biological products contain the natural toxins, antibiotic substances and growth factors synthesized by useful microorganisms. One more group of medicines is received from radiant mushrooms, cultivating them on nutrient mediums by means of biotechnologies. As a result mushrooms produce substances with high insecticidal activity which then include in composition of the medicines "Fitoverm", "Vertimek" and some other.
As all microorganisms are natural components of a biocenosis, ready means of protection are absolutely harmless to the person, birds, fishes, animals and an ecosystem in general.
Advantages of a microbiological method of protection of plants
Microbiological means of protection became widespread thanks to the following advantages: • High efficiency and environmental friendliness.· of compatibility with biological and chemical pesticides.· to selective action concerning the whole range of insects and plants wreckers. • To the short term of expectation: it is possible to reap a crop through two for later final processing. In an arsenal of the gardener there have to be several biological products for pest control. Some of them can be mixed among themselves, receiving thus multifunctional medicine which at the same time has insecticidal, fungicide and rostostimuliruyushchy effect. It is very important to follow rules of preparation of working liquid from pastes and powders in the form of which biological products usually go on sale. It is impossible to forget also about a period of storage as in one and a half years the efficiency of the majority of biological products decreases.
