The composition is prepared into the suspended seed coating agent. The suspended seed coating agent provided by the invention has the advantages of good film-forming performance, uniform coating, high suspension rate, good safety, low toxicity, and the like. The suspended seed coating agent can be widely applied in seed treatments of crops such as wheat, corn, paddy rice, peanut, cotton, and the like. The seed coating agent has a sustained-release effect, such that pesticide dose is reduced. The seed coating agent is safe to human and animals, has no phytotoxicity, and has good environmental compatibility.
Description
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-, two fluoro-1,3-benzo dioxole-4-yl)-1-hydrogen-pyrroles-3-nitrile, molecular formula: C

2S, fludioxonil are a kind of insecticides in the anabasine, are the novel pesticides of a class highly effective and safe, high selectivity, and its effect is similar with nAChR, have tag, stomach toxicity and systemic activity.Be mainly used on paddy rice, vegetables, fruit tree and other crops anti-ly eliminating aphis, the insecticide of Semiptera, coleoptera, diptera and some Lepidoptera class pest such as leafhopper, thrips, plant hopper, have efficient, wide spectrum, consumption is few, toxicity is low, the drug effect lasting period long, to crop without poisoning, use safety, with conventional pesticide without advantages such as cross resistances, remarkable interior suction and osmosis are arranged, and are the another kinds that substitutes high malicious organophosphorous pesticide.Its novel structure, special, performance is compared more excellent with traditional nicotinic insecticide, and large-scale insecticide variety might become international.
Thiacloprid (imidacloprid), chemical name: 1-(6-chloro-3-pyridyl ylmethyl)-N-Nitroimidazoline-2-base amine, molecular formula: C

2, thiacloprid is novel chloro nicotinic insecticide.Main Function is in the neural caudacoria that engages of insect, by be combined interference insect nervous system normal conduction with nAChR, cause the obstruction of neural channel, cause a large amount of accumulation of acetylcholine, thereby make the insect exaltation, whole body spasm, paralysis and dead.Having stronger interior suction, tag and stomach poison function, do not have cross resistance with common insecticides such as pyrethroid, organic phosphates and carbamates, thereby can be used for resistance management, is the efficient medicament of control pierce-suck type and 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: C

3S, Diacloden are a kind of second generation nicotinoids high-efficient low toxicity insecticides of brand new, and insect is had stomach toxicity, tags and systemic activity, are used for foliar spray and soil root irrigation.Rapidly by interior suction, and be transmitted to each position of plant after its dispenser, sucking pest such as aphid, plant hopper, leafhopper, aleyrodid etc. are had good preventive effect.
Seed coating technology is in traditional seed soaking or a kind of very universal seed treatment new technology that grows up of seed dressing technical foundation.Seed with drying or moisture state; wrap with compositions such as the agricultural chemicals that contains binding agent or fertilizer; make and outside seed, form the protective layer that has certain function and coat intensity; this process becomes seed pelleting; the composition that wraps in the seed outside is referred to as kind of a clothing agent, is a kind of for crop or the pesticidal preparations other plant seed treatment, that have film forming characteristics.Planting clothing agent great advantage is to form in the seed outside more firmly film of one deck.Imbibition is not and dissolved in soil to plant the clothing agent, and normal required moisture and the air that germinate of permission seed passes through, and the materials such as contained agricultural chemicals and seed manure slowly discharge.So, to plant the clothing agent and have the soil insect of killing, seedling stage insect, control sprout term disease and systemic disease improve percentage of seedgermination, promote the seedling healthy growth, the effects such as less seed consumption finally reach preventing disease pest control, the strong sprout of keeping a full stand of seedings, improve the purpose of output.
The problem that prevention and elimination of disease and pests the most easily produces is drug-fast generation, and secondly for the control spectrum is single, repeatedly dispenser when the peasant uses causes environmental pollution serious, and the crop residue of pesticide are large, and are unfavorable to human health.The applicant is with bactericide and the pesticide compositional of the different mechanisms of action, reach the two anti-purposes of a spray, effectively prevent and treat the various diseases of crop, enlarge the control spectrum of former single dose, do not directly act on crop, and in crop residue of pesticide decomposition between the growth stage, to crop noresidue or low-residual, to eater's safety, and synergistic effect is remarkable, Environmental compatibility is fabulous, has greatly reduced the agricultural chemicals dosage, has reduced peasant's dispenser cost.
Summary of the invention
Fludioxonil, thiacloprid, clothianidin, the resistance that the long-term use of Diacloden single dose may bring occurs, degradation problem under the drug effect, the Pesticidal combination that the present invention proposes contains the composition pesticide of fludioxonil, by fludioxonil and thiacloprid, clothianidin, Thiamethoxam compound, add an amount of auxiliary agent and make suspension seed-coating agent, be used for control of maize, vegetables, cotton, the application of insect on the wheat, be mainly used in preventing and treating trialeurodes vaporariorum, aphid, grub, wireworm, striped flea-beetle, rice fulgorid, grub, thrips, gray mold, root rot, damping off, bakanae disease, loose kernel smut, the effect of base rot disease is very outstanding, has the effect that a spray two is prevented.
A kind of suspension seed-coating agent of disinsection prophylaxis is characterized in that: fludioxonil and active ingredient B, and wherein the weight ratio of fludioxonil and active ingredient B is 1: 60～60: 1, active ingredient B is selected from clothianidin, thiacloprid, Diacloden; The weight ratio of fludioxonil and active ingredient B is preferably 1: 50～and 50: 1; The weight ratio of fludioxonil and clothianidin is more preferred from 10: 1～and 1: 30; The weight ratio of fludioxonil and thiacloprid is more preferred from 10: 1～and the weight ratio of 1: 30, fludioxonil and Diacloden is more preferred from 10: 1～and 1: 30.
