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 the total 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 stripe disease 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 preventability of 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
The invention belongs to biopesticide and preparation method thereof field, particularly a kind of jinggangmeisu and lentinan novel biopesticide compounding and preparation method.
Background technology
Polysaccharide and water soluble antibiotics utilize the material of the biologically active of biological living or bio-metabolic process generation, or the material that extracts from organism, as the agricultural chemicals of control farm-forestry crop disease, worm, crop smothering.Using polysaccharide separately mainly is that control is viral, though fungal disease is had certain effect, effect is limited.Antibiotic has the effect of better prevention rice fungus diseases evil, selects to develop immunity to drugs but the orientation of pathogen can take place in long-term large tracts of land use, reduces drug effect.Because plant in the growth different phase different diseases can take place, and needs two kinds even more kinds of single agent agricultural chemicals, single agent agricultural chemicals both had been subjected to the single restriction of controlling object, used also inconvenient.Polysaccharide still is that antibiotic all runs into similar problem.
The composite one side of two or more agricultural chemicals can enlarge the sterilization and disinsection spectrum, can also promote drug effect on the other hand, the more important thing is to solve the drug-fast problem that the single agricultural chemicals of long-term use causes.And as biopesticide since the particularity of its structure seldom can find can be mutually composite the biopesticide product, so limited the kind development of biopesticide to a certain extent.And in case find can be composite product, both can reduce the complexity input of research and development neoformation agricultural chemicals, can strengthen the market share of biopesticide again.
Summary of the invention
The purpose of this invention is to provide a kind of Compositional type biopesticide, carry out the lentinan of polysaccharide and the jinggangmeisu of water soluble antibiotics composite, the present invention can enlarge the diseases prevention scope, improve control efficiency, and the orientation that prevents pathogen is selected the drug effect loss condition that causes.
Technical scheme of the present invention is as follows: the prescription and the weight ratio thereof of Compositional type biopesticide of the present invention are as follows:
0.25～0.48 part of lentinan, 0.5～2.5 part of jinggangmeisu, amino acid/11～1.5 part, 95.52～98.25 parts in water.Wherein amino acid is Beijing emerging only specialization length of schooling agent factory commercially available prod.
Preparation process of the present invention is: with 0.25～0.48 part of lentinan, 0.5～2.5 part of jinggangmeisu, 95.52～98.25 parts in amino acid/11～1.5 part and water, mix by a certain percentage, add the auxiliary agent sodium lignin sulfonate, addition is the 1-3% of the gross weight of lentinan, jinggangmeisu, amino acid and water, stirs 30 minutes, gets final product.
Detect foundation:
GB3796 pesticides packaging general rule
GB/T1601-1993 agricultural chemicals pH values determination method
GB/T1604-1995 commercially available agricultural chemical regulation of inspection
The GB/T1605-2001 commercially available agricultural chemical method of sampling
GB/T19136-2003 agricultural chemicals heat storage stability assay method
GB/T19137-2003 agricultural chemicals low-temperature stability assay method
The control project indicator of the present invention: well ridge lentinan total content is: 1 ± 0.5%-5 ± 0.5%.
The preventive effect of preventing and treating stripe disease when lentinan uses separately is generally at 60%-65%; The preventive effect of preventing and treating rice sheath blight disease when jinggangmeisu uses separately is generally at 60%-70%; If with both are composite by a certain percentage when being a kind of agricultural chemicals, the effect of preventing and treating stripe disease and rice sheath blight disease all reaches 80%-88%.We have proved this point in the field efficacy experiment on 2 years four ground that Liaoning Province medicine inspecting institute, academy of agricultural sciences, Fujian, Agricultural University Of Nanjing, Jiangxi Province's agricultural chemicals are done.
After two kinds of agricultural chemicals mixed, the co-toxicity coefficient of each ratio was all greater than 100.Illustrating after two kinds of medicaments mix has synergistic effect, and Rhizoctonia solani Kuhn is had higher biologically active.Recompounded pesticide has had the preventative double effects of interior absorption of jinggangmeisu and lentinan simultaneously concurrently, avoided jinggangmeisu to use the weakness that develops immunity to drugs for many years, medicament prevention itself, treatment double action have been improved again, the more important thing is that cost reduces because composite usage amount minimizing, the drug effect of jinggangmeisu and lentinan of making improves.
