Characteristics of the most widespread biological products are provided in article for protection of plants. The operating beginning of these preparations – bacteria.
The fungi most widely investigated and applied in CIS countries – antagonists of a sort of Trikhoderm. Preparations on their basis are used on all vegetable, decorative, grain and commercial crops against a complex gnily and diseases of root system and the sheet device. Trikhoderma’s high efficiency is caused by that she is the strongest antagonist practically all pathogenic fungi. Developed trikhodermy toxins and antibiotic substances not only oppress development of pathogens, but play important role and in prevention of diseases of plants. The greatest effect of application of Trikhoderma at cultivation of vegetable cultures is reached as a result of carrying out preventive processings, since sprouts (the preparation is brought at disembarkation of plants). In hothouse farms of many countries processing by a preparation of designs of hothouses with a view of creation of a barrier to pathogens is applied.
Biological products on the basis of soil bacteria of a strain Psevdomonas fluorescens are applied against a wide range of fungoid and bacterial diseases, including against bacterioses. Are recommended as highly effective means for preseeding processing of seeds. Processing of tubers of potatoes before landing allows to solve almost completely a problem rizoktonioza and root gnily, and also considerably to lower a porazhayemost of tubers of the parshy. High efficiency of a preparation is reached because during a fermentation a large number of biologically active substances which, getting on seeds and plants is formed, not only disinfect them, but also stimulate rostovy processes. Bacteria Psevdomonas, eating vydeleniye of plants, create a barrier which interferes with penetration into plants of sources of an infection.
Petafag-S it is intended for biological protection against bacterioses on vegetable and garden cultures. The operating beginning – vireos of five bacterial viruses, and also biologically active substances, obrazuyemy at lizise bacteria. It is very effective when processing garden after scraps, and also against a vascular bacteriosis on a garden radish and cabbage.
Gaupsin – a biological product insektitsidno – fungitsidny action on the basis of group bacteria Psevdomonas aureofaciens. It was developed for protection of grain crops and fruit plantings against a set of diseases and wreckers. Possesses insecticidal activity concerning caterpillars of a yablonny plodozhorka, pincers and antagonistic influence on causative agents of fungoid diseases.
Bitoksibatsillin – a biological product on the basis of bacteria Batsillyus turingiensis. It is applied against – the Complex of listogryzushchy cheshuyekryly, plodopovrezhdayushchy and rastitelnoyadny insects on vegetable, grain and long-term plantings. Is one of fixed assets of fight against a web tick in the protected soil. Strikes the wrecker at a larva stage.
Boverin – a biological product on the basis of Beauveriabassiana fungus. It is applied in fight with tripsami, atakzhe it can be applicable in a complex with Vertitsillin against the whitefly. Efficiency of a preparation can be raised considerably, applying it with Aktofitin’s preparation.
Vertitsillin – a biological product on the basis of a fungus verticillium lekaniya. There are strains against the whitefly, pincers and a plant louse. The belokrylochny strain is most widespread. The fungus not only strikes the wrecker, but, settling on padevy vydeleniye, prevents also development of pathogenic fungi, such as sazhisty, and improves a condition of plants.
Lepidotsid - a biological product which basis is the sporous and crystal complex of bacteria of group bacillyus turingiensis. It is recommended to use for fight against a complex of listogryzushchy wreckers, such as: blackvein, browntail, silkworms, scoops, geometrid, moths, meadow moth, listovertka.
Nematofagin – a biological product on the basis of a predatory fungus artrobotris an oligospor, is intended for fight against gallovy nematodes in hothouses. It destroys nematodes a mechanical way and literally devours them.
All listed preparations more effective to use in the liquid state. However term of their storage not long also makes from 1 to 9 months. But this shortcoming is with interest compensated by the following advantages: application of live culture considerably accelerates time of action of a preparation in comparison from the sporous; in the course of a fermentation a large number of biologically active substances which in a combination to microcells and a nutrient medium have on plants roststimuliruyushchy effect is formed; the problem of an allergy which is taking place at use of sporous forms acts in film; carrying out preventive processings allows to plan deliveries of preparations, instead of to keep them in stock.
