Problems solved by technology

That is, the composition of the above-mentioned U.S. patent is prepared by grinding grains such as barley, millet, rice or wheat, and then mixing sodium alginate or kaolin clay into a granular form. The surface of these particles is coated with a sticking agent, but the survival time of microorganisms is less than 11 days, and the storage time is no more than 14 days, so the industrial application is very limited
In golf courses in Korea, major diseases of turfgrasses include large patch (causal bacteria: Rhizoctonia solani), dollar spot (causal bacteria: creeping bentgrass dollar spot Germs (Sclerotinia homoeocarpa)), etc. Since the turfgrass of golf courses is difficult to replace, these soil-borne diseases are managed by chemical pesticides, so the hidden danger of chemical pollution is high

Embodiment approach

[0054] implementation preparation

[0055] The fungi used in the present invention can be obtained from sclerotia of phytopathogenic fungi among fungi reported to be capable of forming sclerotia (Smith ME, Henkel TW., Rollins JA. 2015. How many fungi make scleortia? Fungal Ecology 13, 211-220) constitute.

[0056] Among the sclerotium-forming fungi, particularly, sclerotia obtained from one or more fungi belonging to the genus Sclerotinia, Sclerotinia, and Rhizoctonia can be used, and the sclerotia composition can also contain sclerotia The carbon source, nitrogen source, etc. or nutrients containing trace elements required for germination and development of the plant can be designed in different ways according to different target plants.

[0057] Preferably, the water-absorbing material used in the sclerotia composition may have the property of absorbing water more than 10 times its own weight, thereby providing the effect of prolonging the water supply time, so that nutrien...

Embodiment 1

[0060] Embodiment 1. The viability comparison of sclerotia in dry environment

[0061] In a dry environment, compare the viability of mycelial cultures and sclerotia. The sclerotium (hereinafter referred to as "sclerotia 1") of Sclerotinia trifolii BWC98-105 (Accession No.: KACC93004P, hereinafter referred to as "sclerotia 1") which is a sclerotia-forming bacterium and Sclerotinia delphinium Sclerotia (hereinafter referred to as "sclerotia 2") of BWC04-107 (Accession No.: KACC93031P, hereinafter referred to as "sclerotia-forming bacteria 2"), a mycelial culture in the state of hardened sclerotia itself and mycelium culture Compare.

[0062] The sclerotia of sclerotia-forming bacteria were ensured by culturing on potato dextrose agar medium (potato dextrose agar, PDA; Difco) at a temperature of 25°C for more than 2 weeks. Substratum culture was carried out for 5 days to ensure the mycelial culture of sclerotia-forming bacteria at the stage before sclerotia formation.

preparation example 1 to preparation example 7

[0069] Preparation Example 1 to Preparation Example 7. Preparation of Sclerotia Composition

[0070] Based on the above-mentioned Example 1, the solid composition was completed with the composition ratio shown in Table 2. First, put the prepared sclerotium into the sugar coating machine, add the powder of the remaining composition while rotating, spray water appropriately to coat the sclerotia, and repeat the process of adding powder and spraying water again for coating , to prepare spherical particles with a diameter of about 4 mm and dry, thereby completing the composition of the preparation example. The composition ratios shown in Table 2 are composition ratios excluding moisture.

[0071] In the composition, commercially available glucose powder was used as a carbon source, defatted soybean meal powder was used as a nitrogen source, and citric acid powder was used as a preservative. When formulating granules, sodium alginate powder was used as a water-absorbing material ...

Abstract

The present invention relates to a fungal sclerotium composition capable of controlling a target plant including Sicyos angulatus designated as an invasive plant, or suppressing the occurrence of soil-borne diseases including Sclerotinia dollar spot. More specifically, by properly using a composition comprising a sclerotium from fungi forming the sclerotium, nutrients of the sclerotium-forming fungi, and an absorbent material, the present invention can effectively control Sicyos angulatus and Sclerotinia dollar spot, and greatly solve problems occurring in the production, storage and distribution process as well as the usage process of biological products containing microorganisms.

Description

technical field [0001] The present invention relates to solid compositions for the management of plants comprising sclerotia of fungi and their use, in particular to the biological control of weeds and soil born diseases in plant management methods. The present invention relates to a solid composition comprising sclerotium that is effective in inhibiting the growth of a target plant (target plant) to be managed, such as burcucumber (Sicyos angulatus), designated as an ecosystem-disturbing plant, including turfgrass Occurrence of soil-borne diseases including dollar spot (Sclerotinia homoeocarpa). Furthermore, the present invention relates to a solid composition comprising sclerotia forming fungi (fungus), nutrients necessary for the growth of the sclerotia strain, and a water-absorbing material capable of accommodating the sclerotia and nutrients, and uses thereof. Background technique [0002] There are about 3,611 species of herbs growing in Korea, including 18 species (6...
