Abstract
The invention discloses a biological pesticidal and sterilizing composition containing validamycin A and avermectin and a production method thereof. The composition comprises the following effective components: 2-20% of validamycin A and 1-5% of avermectin. The production method is realized by the following steps: adding the raw materials into an enamel stirred tank, evenly mixing, and pulverizingby air flows or milling to obtain the biological pesticidal and sterilizing composition containing validamycin A and avermectin, which is in the state of the wettable powder or suspending agent. Since the validamycin A and the avermectin are compounded for use, the composition has the characteristics of low toxicity, low residue, wide pesticidal range, favorable lasting effect, low cost and especially biological prevention and control capability without environmental disruption, and thereby being an ideal biological pesticide for preventing and controlling various plant diseases and insect pests of rice.
Description
Technical field
The present invention relates to pesticide production technology field, particularly prevent and treat the multiple damage by disease and insect technical field of pesticides of paddy rice.
Background technology
Rice pest is the major reason that hazard rice is produced, and realizes that the control of rice pest harmless boilogical is the developing direction and the objective of the struggle in agricultural plant protection field.In recent years, though country prohibites and use high-toxic pesticide on paddy rice, but for want of efficient pest control chemicals in actual agricultural production process and use the phenomenon of high poison, persistent pesticide also comparatively general, therefore, the novel biopesticide of research and development high-efficiency low-toxicity, the low-residual development trend that is inevitable.
Jinggangmeisu (jingangmycin) is water soluble antibiotics one glucoside compounds that is produced by the mutation of water streptomycete well ridge.Have 6 components, main active substances is jinggangmycin A and B.Be the very strong agricultural antibiotic of a kind of systemic action, after the mycelia of Rhizoctonia solani Kuhn touches jinggangmeisu, can absorbed very soon and in thalline, conduct, disturb and the growth of inhibition somatic cells normal growth, thereby play therapeutic action by somatic cells.Jinggangmeisu also can be used for preventing and treating wheat sharp eyespot, rice green smut etc.
Use jinggangmeisu separately and prevent and treat rice disease, thereby can not prevent and treat the main insect pest of paddy rice simultaneously, do not reach the medication target of saving of labor's abridged edition, integrated control.
Avermectin (abamectin) is a kind of macrolide disaccharide compounds.Be the natural products that from edaphon, separates, insect and mite class had tag and stomach poison function and faint fumigation action is arranged, no systemic action.But it has very strong osmosis to blade, can kill subepidermal insect, and the longevity of residure is long.It does not kill ovum.What its mechanism of action was different with general insecticide is that it disturbs the neurophysiology activity, stimulate and discharge the r-aminobutyric acid, and the r-aminobutyric acid has inhibitory action to arthropodan nerve conduction, mite class adult, if mite and insect and larva with paralysis symptom promptly appears after medicament contacts, inertia is not got food, and is dead after 2-4 days.Because of not causing that insect dewaters rapidly, so its lethal effect is slower.But though predatism and parasite are had direct killing effect, because of plant surface is residual few, therefore little to the damage of beneficial insect.Equally, use the plain control of Avermectin rice insect pest separately, can not realize preventing and treating simultaneously the medication target of the integrated control of the main disease of paddy rice.
Summary of the invention
The objective of the invention is to control the multiple deficiency that biopesticide very lacks and existing biopesticide list agent exists at present efficient, wide spectrum damage by disease and insect is double, providing a kind of is a kind of Biocidal bactericidal composition that contains jinggangmeisu and Avermectin of product forms with wetting powder or suspending agent.
Active ingredient of the present invention is jinggangmeisu and Avermectin, and described jinggangmeisu accounts for 2～20% of composition gross mass, and Avermectin accounts for 1～5% of composition gross mass.
The present invention shows all has stronger insecticidal activity and preventing disease theraping effect to agricultural insect pest, disease, can be widely used in preventing and treating the multiple damage by disease and insect of paddy rice.This Biocidal bactericidal composition is different from existing other desinsections, bactericidal composition or the agent of agricultural chemicals list, adopt the reasonable combination of jinggangmeisu and these two kinds of biopesticides of Avermectin, can delay the drug-fast generation of damage by disease and insect, use simple, safety, control efficiency is good, and residual quantity is low environmentally safe, promote crops safety and high-quality production, agricultural production and income is played an important role.
The present invention adopts the use that is mixed of jinggangmeisu and two kinds of biopesticides of Avermectin, it had both kept desinsection, sterilization wide spectrum and the advantage good to the control efficiency of damage by disease and insect of jinggangmeisu and Avermectin, can overcome the shortcoming of existence again, realize the target of diseases and pests of agronomic crop harmless boilogical control, reduction is to other biological toxicity, the minimizing chemical substance is residual crops, enlarge the pesticide-germicide spectrum, reduce cost, crops such as paddy rice are produced the requirement that biopesticide is used to adapt to China.
Also comprise auxiliary agent and filler in the present composition, described auxiliary agent accounts for 2～25% of composition gross mass, and filler accounts for 50～95% of composition gross mass.
In order to form wetting powder, above-mentioned auxiliary agent is made up of dispersant and wetting agent, and described dispersant accounts for 1～20% of composition gross mass, and wetting agent accounts for 1～5% of composition gross mass and forms.Wherein, dispersant can adopt lignosulfonates, NNO, draw back a kind of or any two or three mixture of powder; Lignosulfonates are selected calcium lignosulfonate or sodium lignin sulfonate for use.Wetting agent adopts sodium alkyl benzene sulfonate or alkyl benzene calcium sulfonate.That filler adopts is silica-based, a kind of or mixture in the precipitated calcium carbonate, white carbon, silica-based employing potter's clay, kaolin and diatomite etc.
In order to form suspending agent, above-mentioned auxiliary agent is made up of dispersion moisture agent and antifreeze, thickener, defoamer, described dispersion moisture agent accounts for 1～15% of composition gross mass, antifreeze accounts for 0.3～3% of composition gross mass, thickener accounts for 0.4～5% of composition gross mass, and defoamer accounts for 0.3～2% of composition gross mass.Wherein, dispersion moisture agent adopts polyoxyethylene triphenylethylene phosphenylic acid salt, or alkylnaphthalene sulfonate, or a kind of or mixture in the alkylphenol polyoxyethylene; Antifreeze adopts antifreeze to adopt alcohols, selects propane diols or glycerine or ethylene glycol for use; Thickener adopts xanthans or aluminium-magnesium silicate; Defoamer adopts silicone defoaming agent; Filler adopts water.
Another purpose of the present invention provides above composition manufacturing method:
By said ratio weighing jinggangmeisu and Avermectin, auxiliary agent and filler, after earlier jinggangmeisu, Avermectin and auxiliary agent, filler fully being mixed in the enamel stirred tank, after airslide disintegrating mill pulverizing or sand mill grinding, mix again and make finished product.
Technology of the present invention is simple, reasonable, is easy to production operation, and product stability is good, and finished product meets or be higher than the every mandatory index request of country to wetting powder or suspending agent product.
