In a note efficiency of use of biological products is briefly shined, and also the new microbic preparation Hetomik is described.

Practical interest to a biomethod is caused by that it safe for the person and warm-blooded animals. Biological preparations don’t pollute environment, show high selective action and have inexhaustible resources for continuous building of volumes.
The world practice of use of biological agents as means of protection of plants from wreckers testifies that from natural insecticides entomopatogenny bacteria of Bacillusthuringiensis most often use. More than one thousand strains of Bacillusthuringiensis which it is selective virulentny against certain types of wreckers is known.
In Ukraine on the basis of Bacillusthuringiensis L-4 the new highly effective preparation of Batsilloturing is created. Application of this preparation against the Colorado beetle on potatoes provided reliable protection of plants and a considerable increase of a crop.
On the basis of Bacillussubtilis Fitosporin’s preparation which is effective against phytopathogenic mushrooms and bacteria is developed.
Well proved on many crops against a number of diseases Trikhodermin’s preparation.
Perspective bioagents of microbic preparations are bacteria of the sort Pseudomonas which are capable to produce siderofor. The main property of siderofor – a kompleksirovaniye of iron available to mikroargonizm in the absence of which phytopathogenic mushrooms and other mikroargonizm stop the development. Besides, bacteria of the sort Pseudomonas are capable to dissolve phosphoric connections, to synthesize regulators of growth of plants, to utilize xenobiotics and so forth.
The new microbic preparation was developed for improvement of a food of plants and protection them from causative agents of root diseases Hetomik. It is recommended against such diseases, as: the root decayed grain and leguminous, gray and white gnily peas, a soya, sunflower and vegetable cultures, fuzarioza and fuzariozny withering of peas, a soya, a lupine, flax, long-term herbs, vegetable cultures, against fuzariozny decay and korneeda beets, ordinary and silvery parshi potatoes, rizoktonioza vegetable and potatoes. A preparation apply by processing of seeds or entering into the soil at the same time with organic fertilizers. Productivity of all cultures thus increases by 15-30 %. Hetomik is much more effective than chemical analog of Vitavaks 200.
Nevertheless, use of only a biological method for protection of plants against wreckers and diseases is complicated for some reasons and consequently it is necessary to apply the integrated system of protection of plants which includes a combination of biological, agrotechnical, selective and genetic and organizational and economic methods of protection.
