Abstract
The invention discloses a suspension seed coating agent for pest killing and disease prevention. The suspension seed coating agent is mainly characterized in that effective active ingredients are fludioxonil and an effective ingredient B; the weight ratio of the fludioxonil to the effective ingredient B is 1:60 to 60:1; the composition is made into the suspension seed coating agent. The suspension seed coating agent has the advantages that the film forming performance is good; the coating is uniform; the suspension rate is high; safety and low toxicity are realized, and the like. The suspension seed coating agent can be widely used for seed processing of crops such as wheat, corn, rice, peanut and cotton. The slow release effect is achieved; the pesticide consumption is reduced; the suspension seed coating agent is safe for people and livestock; no pesticide damage is caused; the environment compatibility is good.
Description
The application is divisional application, and original application is that " one is killed for the patent application of Shaanxi Welch Crop Protection Co., Ltd.
Worm disease prevention suspensible seed coating agent ", the Application No. 2012100553180 of original application, original application day is 2012.03.06.
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of pesticidal disease-prevention suspending seed coating agent.
Background technology
Fludioxonil (fludioxonil), chemical name: 4-(2,2-bis-fluoro-1,3-benzodioxole-4-
Base)-1-hydrogen-pyrroles's-3-nitrile, molecular formula: C12H6F2N2O2, this medicine is broad-spectrum touch-out bactericide, for Seed Treatment, can prevent
Control major part seed-borne fungi and the fungal disease of soil infection.Soil is stablized, forms protection zone at seed and seedling rhizosphere,
Prevent germ from invading.Structure novel, is difficult to and other bactericide generation cross resistance.
Clothianidin (Clothianidin), chemical name: (E)-1-(2-chloro-1,3-thiazoles-5-ylmethyl)-3-methyl-
2-2-nitroguanidine, molecular formula: C6H8ClN5O2S, fludioxonil is a kind of insecticide in anabasine, is a class highly effective and safe, height
Selective novel pesticide, its effect is similar with nAChR, have tag, stomach toxicity and systemic activity.Mainly
Anti-on paddy rice, vegetables, fruit tree and other crops eliminate aphis, leafhopper, thrips, the Semiptera such as plant hopper, coleoptera, Diptera and
The insecticide of some Lepidoptera class pest, have efficiently, wide spectrum, consumption are few, toxicity is low, drug effect lasting period length, to crop without medicine
The advantages such as evil, use safety and conventional pesticide no interactions resistance, have interior suction and the osmosis of brilliance, are that replacement is high malicious organic
The another kind of phosphorus agricultural chemicals.Its novel structure, special, performance is the most excellent compared with tradition nicotinic insecticide, it is possible to one-tenth
For global large-scale insecticide variety.
Thiacloprid (imidacloprid), chemical name: 1-(6-chloro-3-pyridyl ylmethyl)-N-Nitroimidazoline-2-
Base amine, molecular formula: C9H10ClN5O2, thiacloprid is novel chloro nicotinic insecticide.After mainly acting on insect nerve joint
Film, by being combined with nAChR, interference insect nervous system normal conduction, cause the obstruction of neural channel, make
Become a large amount of accumulation of acetylcholine so that insect exaltation, general spasticity, paralysis and dead.There is stronger interior suction, tag
And stomach poison function, there is no cross resistance with common insecticides such as pyrethroid, organic phosphates and carbamates, thus
Can be used for resistance management, be preventing and treating pierce-suck type and the efficient medicament of pests with chewing mouthparts.
Diacloden (Thiamethoxam), chemical name: 3-(2-chloro-1,3-thiazoles-5-ylmethyl)-5-methyl isophthalic acid, 3,
5-oxadiazines-4-base fork (nitro) amine, molecular formula: C8H10ClN5O3S, Diacloden is the second generation nicotinoids of a kind of brand new
High-efficient low toxicity insecticide, has stomach toxicity, tags and systemic activity insect, for foliar spray and soil root irrigation.It is executed
Rapidly by interior suction after medicine, and it is transmitted to each position of plant, sucking pest such as aphid, plant hopper, leafhopper, aleyrodid etc. are had good
Preventive effect.
Seed coating technology is grow up in traditional seed soaking or seed dressing technical foundation a kind of very universal
Seed Treatment new technology.By being dried or the seed of moisture state, wrapped with compositions such as the agricultural chemicals containing binding agent or fertilizer, made
Being formed outside seed and have certain function and the protective layer of cladding intensity, this process becomes seed pelleting, wraps in outside seed
Composition be referred to as seed coat agent, be a kind of for crop or other plant Seed Treatment, the agricultural chemicals system with film forming characteristics
Agent.Seed coat agent great advantage is to form one layer of more firm film outside seed.Seed coat agent is imbibition in soil
And be not dissolved, it is allowed to seed normally germinates required moisture and air passes through, and the material such as contained agricultural chemicals and seed manure is slowly released
Put.So, seed coat agent has kills subterranean pest-insect, insect in seedling stage, preventing and treating sprout term disease and systematicness disease, improves germination
Rate, promote seedling healthy growth, the effect such as less seed consumption, it is finally reached preventing disease pest control, strong sprout of keeping a full stand of seedings, improves the mesh of yield
's.
Prevention and elimination of disease and pests is easiest to generate the problem that drug-fast generation, secondly single, when peasant uses for preventing and treating spectrum
Repeatedly dispenser, causes environmental pollution serious, and crop residues of pesticides are big, unfavorable to human health.Applicant is by the difference mechanism of action
Bactericide and pesticide compositional, reach the purpose that a spray is double anti-, effectively the preventing and treating various disease of crop, expands the preventing and treating of former single dose
Spectrum, and it is not directly placed on crop, and during crop grows up, residues of pesticides are decomposed, to crop noresidue or low-residual, to food
User's safety, and synergistic effect is notable, and Environmental compatibility is fabulous, considerably reduces pesticide usage amount, reduces peasant's
Dispenser cost.
Summary of the invention
Resistance that fludioxonil, thiacloprid, clothianidin, Diacloden single dose Long-Time Service may bring occurs, degradation under drug effect
Problem, the Pesticidal combination that the present invention proposes contains the composition pesticide of fludioxonil, by fludioxonil and thiacloprid, clothianidin,
Thiamethoxam compound, adds appropriate auxiliary agent and makes suspension seed-coating agent, for preventing and treating insect on corn, vegetables, cotton, wheat
Application, is mainly used in preventing and treating trialeurodes vaporariorum, aphid, grub, wireworm, striped flea-beetle, planthopper, grub, thrips, gray mold, root
Maize ear rot, damping-off, bakanae disease, smut, base rot disease effect the most prominent, there is the effect that a spray two is anti-.
A kind of suspension seed-coating agent of disinsection prophylaxis, it is characterised in that: fludioxonil and active ingredient B, wherein fludioxonil with have
The weight ratio of effect composition B is 1 60～60 1, and active ingredient B is selected from clothianidin, thiacloprid, Diacloden；Fludioxonil with effectively become
