Abstract
The invention discloses a natural mineral fungicide. The natural mineral fungicide comprises the following components in parts by weight: 0.5-2 parts of gypsum, 2-4 parts of sulfur, 0.5-2 parts of brown coal and 1-3 parts of mica. A preparation method comprises the following steps: crushing minerals including the gypsum, the sulfur, the brown coal, the mica and the like into sizes being more than 325 meshes; treating the mixture with dilute nitric acid and precipitating; carrying out solid-liquid separation, and then concentrating and drying; and crushing to obtain a finished product. The natural mineral fungicide prepared from natural mineral extracts can be used for effectively reducing the utilization of an organically-synthesized fungicide, so that the environmental pollution is reduced, the agricultural expenditure is reduced and the agricultural benefits are increased; and meanwhile, the natural mineral fungicide has a very remarkable prevention and treatment effect on pine seedling blight which widely occurs in forestry nursery in the world, and the prevention and treatment effect can be up to be more than 80%.

The invention allows for the preparation method of above-mentioned natural minerals bactericide, comprise the steps:
By the gypsum of formula ratio, sulphur, brown coal and mica grinding and sieving, be that 1.5 ~ 2.5g/ml adds 25wt% dust technology according to the mass volume ratio of said mixture and 25wt% dust technology, 3 ~ 5h is stirred under the condition of 18 ~ 30 DEG C, Separation of Solid and Liquid, get its liquid under 45 ~ 55 DEG C of conditions, to carry out rotary evaporation concentrate, after the solid obtained is dried under 75 ~ 85 DEG C of conditions, then pulverize, cross 50 mesh sieves, namely obtain natural minerals bactericide.
Preferably, described gypsum, sulphur, brown coal and mica cross 325 mesh sieves after pulverizing.
Further, the present invention proposes the above-mentioned application of natural minerals bactericide in controlling plant diseases.
Particularly, in application process, after described natural minerals bactericide can being diluted with water to 3 ~ 5 ‰, spray nursery stock cauline leaf.
When for nursery stock root, pouring nursery stock root after preferably described natural minerals bactericide being diluted with water to 3 ~ 5%.
Beneficial effect: compared with prior art, the natural minerals bactericide utilizing natural mineral matter extract to prepare reduces the use of organic synthesis bactericide, reduce environmental pollution, reduce agricultural expenditure, increase agricultural benefit, this natural minerals bactericide is to the loose seedling blight control efficiency highly significant extensively betiding countries in the world forestry nursery simultaneously, can reach more than 80%.This natural minerals bactericide under working concentration to protected plant without any harmful effect.
