Abstract
The invention discloses insect and bacterium killing granula with dinotefuran. The insect and bacterium killing granula is composed of active components and auxiliary components, the active components comprise the dinotefuran and metalaxyl-M, and the weight percentage of the dinotefuran to the metalaxyl-M accounts for 0.2 percent to 20 percent of the total mass of the granula. The dinotefuran and the metalaxyl-M are compounded, so that the insect and bacterium killing granula has the remarkable synergistic effect and is long in lasting period, resistance to pesticide is not likely to be generated, the prevention and controlling effect is improved, and the amount of the applied pesticide and prevention and control cost are lowered.
Description
Technical field
The invention belongs to the agent of a kind of agricultural insecticidal antimicrobial granules, be specifically related to MTI-446 and the composite pesticide-germicide granule of Metalaxyl-M.
Background technology
MTI-446 (dinotefuran) is the exploitation of Mitsui East Asia KCC and the novel nicotinamide insecticide of going on the market in 2002.It is the insecticide of the unique not chloride atom of anabasine insecticide and aromatic ring, be called as third generation anabasine insecticide, there is super-high-efficient, wide spectrum, consumption is few, toxicity is low, lasting medicine, to crop without the advantage such as poisoning, use safety.This medicament has the features such as tag, absorption is strong in stomach toxicity and root, quick-acting good, the lasting period is long, insecticidal spectrum is wide, has excellent preventive effect, and namely show very high insecticidal activity at very low dosage to sucking pest.Be mainly used in the aphid in the various crop such as control wheat, paddy rice, cotton, vegetables, fruit tree, tobacco leaf, leafhopper, plant hopper, aleyrodid and resistant strain thereof, simultaneously effective to various insects such as coleoptera, diptera, Lepidoptera, orthoptera, Hymenopteras, and efficient to the sanitary insect pest such as blattaria, housefly.In MTI-446, absorption is strong, make granule and spread fertilizer over the fields in crop root, can be absorbed rapidly by crop root, and fast transport is to whole plant, in the propagation of insect intrusion initial stage Control pests effectively.
Metalaxyl-M (Metalaxy-M) belongs to phenyl amide series bactericidal agent; chemical name is N-(2-Methoxyacetyl)-N-(2; 6-xylyl)-D-alanine methyl esters; its action principle is by leaf, stem, root absorption; the synthesis of interference rRNA; the synthesis of Antifungi protein, for control to be caused by air-flow and soil-borne temperate zone, subtropics, tropical crop Oomycete Peronosporales disease.Metalaxyl-M is the R isomer of common metalaxyl, is a kind of high systemic fungicide, has protection and therapeutic action, and drug effect is high, residual low, has good Environmental compatibility.Be mainly used in preventing and treating Pseudoperonospora cubensis, phytophthora root rot bacterium, the crop pest such as vegetables, fruit tree, tobacco, oil plant, cotton, grain caused by rotten mildew fungus.In Metalaxyl-M, absorption is strong, makes granule and spreads fertilizer over the fields in crop root, can prevent and treat the root diseases such as crop damping off, phytophthora root rot, be organized simultaneously, effectively prevent the disease such as downy mildew, epidemic disease by crop root Assimilation and conductivity to Plant aboveground.
Vegetable aphid belongs to homoptera pest, and be one of primary pest of vegetables, all there is generation vegetable-growing area in all parts of the country, and mainly intensive at vegetable seedling, tender leaf, stem and subaerial blade back with adult, nymph, thorn inhales juice.Because the breeding amount of aphid is large, intensively to cause harm, suck crop juice, be that plant is weak withered, cause the vegetables that are injured seriously to dry out and nutrition, form blade face shrinkage, jaundice, blade is caused " to cave in " time serious, can be spread disease viral disease in addition, causes virus disease to occur, result in greater loss.
Vegetables phytophthora root rot, in recent years, the occurrence and infection that oomycetes phytophthora infects the phytophthora root rot caused is more and more heavier, and especially Winter-Spring stubble and stubble vegetables morbidity in early spring seriously, more than dead, even ruin seedling total crop failure.Morbidity just all produces foxiness on basal part of stem or root, depression after expanding gradually, and time serious, scab is around basal part of stem or root one week, and overground part is withered gradually.Hot and humid or low temperature and low humidity is all conducive to the generation of this disease.
Summary of the invention
The technical problem to be solved in the present invention is to carry out rational mixture by MTI-446 and Metalaxyl-M, and the preparation method of the granule containing these two kinds of compositions is provided, for preventing and treating vegetable aphid and the germ root disease of Oomycete, repeatedly repeat dispenser when plant disease and insect pest occur the same period make troubles to user to solve, and repeat the adverse effects such as poisoning that dispenser causes.
The present invention is the composite pesticide-germicide granule of a kind of MTI-446 and Metalaxyl-M, and it is made up of active component and auxiliary element, and described active component comprises MTI-446 and Metalaxyl-M, and its part by weight is the 0.2-20% of granule total amount.
Preferably, in described active component, the mass ratio of its MTI-446 and Metalaxyl-M is 0.1-10:10-0.1.
The auxiliary element used in composition of the present invention comprises wetting agent, dispersant, sustained release agent, carrier.The part by weight of wetting agent is the 2-5% of granule total amount, and dispersant weight ratio is the 2-5% of granule total amount, and sustained release agent part by weight is 3% of granule total amount, and vehicle weight ratio is the 87-89% of granule total amount.
Dispersant of the present invention is the one in triphenyl vinyl phenol polyoxyethylene ether phosphate, alkylphenol-polyethenoxy base ether sulfonate, naphthalene sulfonate, the salt of naphthalene sulfonic acid-formaldehyde condensation product, sodium lignin sulfonate or calcium lignosulfonate, sodium cellulose glycolate, polyoxyethylene polyoxypropylene base ether block copolymers.
Wetting agent of the present invention is the one in alkylaryl polyoxyethylene ether sulfate, alkylphenol polyoxyethylene, aliphatic alcohol polyethenoxy base ether, alkylnaphthalene sulfonate, alkylaryl polyoxyethylene ether sulfate.
Carrier of the present invention is the one in bentonite, diatomite, white carbon, precipitated calcium carbonate, corn starch.
The preparation method of granule of the present invention is for adsorb its female powder of rear acquisition by a certain percentage by Metalaxyl-M and absorption carrier, again female powder, the former medicine of MTI-446, wetting agent, dispersant, sustained release agent, carrier are mixed, pulverize through airslide disintegrating mill and make it reach certain fineness.Then add a certain amount of adhesive wherein, carry out extruder grain by Squeezinggranulator, obtain stay-in-grade MTI-446 Metalaxyl-M granule.
Beneficial effect of the present invention:
Composite by MTI-446 and Metalaxyl-M, have significant synergies, the lasting period is long, not easily develops immunity to drugs, and improves control efficiency, reduces formulation rate and cost accounting.
Granule prepared by the present invention is a kind of solid pharmaceutical preparation, has directionality, without dust from flying during dispenser, environmentally friendly; The rate of release of active ingredient in granula can be controlled, extend the lasting period; Due to not containing organic solvent, meet the requirement of environmental protection Agrochemicals, and preparation processing technique is simple, easy to use, suitable for large area applications.Can be used for the control of vegetable aphid and the germ root disease of Oomycete, especially have good control to vegetable aphid, phytophthora root rot.
