Abstract

The invention discloses a novel biopesticide compounding validamycin with lentinan. The novel biopesticide comprises the following ingredients in percentage by weight: 0.25 to 0.48 part of lentinan, 0.5 to 2.5 parts of validamycin, 1 to 1.5 parts of amino acid and 95.52 to 98.25 parts of water. The technological process for preparing the novel biopesticide comprises the following steps: proportionally mixing the lentinan, the validamycin, the amino acid and the water, adding an addition agent, wherein the addition agent is sodium lignin sulfonate the addition of which is 1 to 3 percent of thetotal weight of the lentinan, the validamycin, the amino acid and the water; and finally stirring for 30 minutes. The effects of the compounded biopesticide on preventing and treating the rice stripedisease and the rice sheath blight respectively reaches 80 to 88 percent, and in the mean time, the novel biopesticide has the double effects of internal suction of the validamycin and preventabilityof the lentinan; and due to compounding, the usage amount of the validamycin and the lentinan is reduced, the pesticide effect is improved, and the cost is lowered.

Description

Technical field [0001] The invention belongs to the field of biological pesticides and preparation methods thereof, and particularly relates to a novel biological pesticide compounded with Jinggangmycin and lentinan and a preparation method thereof. Background technique [0002] Polysaccharides and water-soluble antibiotics use biologically active substances produced by living organisms or biological metabolic processes, or substances extracted from living organisms, as pesticides to prevent and control agricultural and forestry crop diseases, insects, and weeds. Polysaccharide used alone is mainly used to prevent and treat viruses. Although it has a certain effect on fungal diseases, the effect is limited. Antibiotics have a good effect in preventing and treating rice fungal diseases, but long-term use in large areas will cause directional selection of pathogens to produce antibiotic resistance, reducing the effectiveness of the antibiotics. Since plants will suffer from d...
