DD298038A5 - PROCESS FOR PRODUCING A MYZEL GRANULATE - Google Patents

Abstract

The invention relates to a method for producing a mycelial granulate. The object of the invention is to develop a method for the production of a mycelial granulate, which can be used for apathogenic fungal strains as a growing material and for the application of the inoculum during the normal drilling process. According to the invention, this is achieved by applying to a wearer a thin pill layer as a nutrient layer for the non-pathogenic fungus. This is done by intervalwise spraying a liquid film of carboxymethylcellulose and alternating rolling in various finely pulverized Muehlenabprodukten. This mycelial granule can be applied together with the seed either in one sowing unit, but better in two sowing units. The invention can be used in plant production in the context of integrated pest management {mycelium granules; Gaeumannomyces graminis; Phialophora; Pests; Muehlenabprodukte; blackleg; Grain}

Description

Field of application of the invention

The invention relates to a method for producing a mycelial granulate.

It can be used in plant production as part of integrated pest management.

Characteristic of the known state of the art

The causative agent of blackleg of cereals, Gaeumannomyces graminis (SACC.) ARX & OLIVIER var. Tritici WALKER, as described repeatedly in the literature, causes severe damage to the root systems in crops with a high proportion of cereals, which results in high loss of yield especially in infestations of the young plants , Like many other soil-borne diseases, this disease can not be combated economically (TROLLDENIER, 1984). The methods of biological control are therefore of great interest in the implementation of market-oriented cultivation structures. For example, vaccinations with avirulent Gaeumannomyces graminis isolaton and isolates of apothogenic Phialophora species have been successfully carried out. However, the previously internationally described field test results are still subject to high variability. As a cause for u. a. Method of application of inoculum such as application technique (Pilling LUKAS and PERRATON, 1983) as well as time and method of soil treatment considered. The prerequisite for an effective application technique is the economic production of the inoculum for the field trials and production experiments in order to test the microorganisms used under practical conditions or to develop practice-relevant application methods. As previously used inoculum carriers the following listed substances were used:

- sterile wheat straw (GARRETT, 1938, WONG, 1984, GLENN et al., 1988)

- sterile oat grains (WONG and SOUTHWELL, 1979; 1980; WILDERMUTH et al., 1984; WOOD and ROBSON, 1984; SPEAKMAN, 1984; COOK et al., 1986; SWARD and KOLLMORGEN, 1986; GARCIA and MATHRE, 1987; HUBSR et al., 1989)

- sterile oat grains mixed with perlite (MARTYNIUK and MUSKOW, 1984)

sterile wheat grains (Bockmann, 1962, Ehle, 1966, CAMPELL and FAULL, 1979)

sterile barley grains (JADOT et al., 1982)

- sterile millet grains mixed with quartz sand (MAC NISH at al., 1986)

- 3% maize meal sands (DEACON, 1973, ASHER, 1972, HOLDEN, 1980) and

Aluminum silicate with 2% malt extract (RAWLINSON and MUTHYALV, 1977).

This list clearly shows the economic inadmissibility of this type of inoculum for larger-scale exploration.

Object of the invention

The object of the invention is to provide a method for the production of a mycelium granules, with which a biological control of blackleg is effectively possible or an income stabilization can be achieved on a field scale.

Explanation of the essence of the invention

The object of the invention is to develop a seduction for the preparation of a mycelium granules, which can serve for apathogenic fungal strains as a seed material or for the application of the inoculum during the normal drilling process.

The object is achieved in that applying a thin Pillierungsschicht on a carrier (round seeds from the mill offal or superimposed Wiesenlieschgrassamen). A liquid film of carboxylmethyl cellulose is applied to the carriers at intervals and cured by alternately rolling in various finely pulverized mill products.

Due to their high cereal waste content, these mill waste products are a sufficient nutrient substrate for promoting the growth of the selected fungal strains. The fungi manifest themselves on this pilling layer and penetrate in the case of grass seed as carrier, resulting in a storability of the mycelial granules of at least 6 months.

This mycelial granules can be applied together with the seed either in a Säeinheit, but better, by the separate metering, in two sowing units.

The advantage of the method according to the invention is that

- a protection of the young cereal plants is achieved before the naturally occurring in the testes aggressive pathogens of blackleg,

- the use of mycelium granules positively influences the planning of market-oriented cultivation processes,

- no additional treatment or treatment of the seed is required and

- By applying during the normal Drillvorganpos no significant additional effort for the An- .vonder entste.it.

embodiment

The invention will be explained in more detail with reference to exemplary embodiments.

example 1

As carriers, round seeds (mill waste product) are used

A 0.4% carboxymethylcellulose solution is prepared and applied to the support at intervals by uniform stirring. The moisture film is going through

a) 11.4% (m) of cereal waste from the dust bunker and

11.6% (m) of waste (rubbish rubbish) in front of Gotreideboden or

b) 11.4% (m) of cereal waste from the dust bunker and

2.6% (m) of waste from the Staubmühlo tied.

Example 2

As carrier Wiesenlieschgrassamen apply

The carrier ^r is moistened at intervals by uniform stirring with a 0.4% carboxymethylcellulose solution.

The liquid film is through

a) 10,0% (m) cereal waste from the dust bunker and

9.1% (m) waste from the extraction of the conveyance or

b) 6.3% (m) of waste discarded from the dust mill.

Example 3

The granules prepared in this way are adjusted to a moisture content of 50% and inoculated with the corresponding fungus strains. At a temperature of 25 to 28 ° C, the thus treated granules are incubated. After the granules are completely overgrown, they can be stored in a cool place.
