Description
Technical field
The invention belongs to pesticide production technology field, be specifically related to a kind of MTI-446 synergy suspending agent and preparation method thereof.
Background technology
MTI-446 (dinotefuran) is the third generation nicotinic insecticide of Mitsui chemical company exploitation.This medicament
There is the interior suction osmosis of brilliance, and i.e. show the highest insecticidal activity at the lowest dosage.This medicine insecticidal spectrum is wide, can prevent
Stop the various insects such as various Semipteras, Lepidoptera, Diptera, Orthoptera, Hymenoptera, beetle mesh.This medicament is to mammal, bird
Class and aquatile are fool proof, to crop without poisoning, can be used for numerous crops such as paddy rice, fruit tree, vegetables.
Modern changes quickly, and the just direction towards environmental type is developed, and suspending agent (SC) is exactly one of which, agriculture
Medicine suspending agent is that in pesticidal preparations, developing history is short, the most very fast a kind of formulation, and many herbicides, insecticidal bactericide can
It is processed into this formulation.Agricultural chemicals suspension agent, with water as decentralized medium, is insoluble or poorly soluble in the solid ground pulverizing of former medicine of water, and
By surfactant and the effect of other auxiliary agent, it is allowed to dispersed, forms the tiny higher suspension of a kind of particle, flowable
More stable liquid-solid state system, compared with missible oil, can avoid using substantial amounts of organic solvent；Compared with wettable powder, then without
Dust disperses drift；Toxicity and excitant all ratios to people and animals are relatively low；And the poisoning to crop can be alleviated；Also will not be because of organic molten
Agent and storage transportation in burn, security is higher；The danger being caused user and whole environment is reduced to quite
Low degree.Further, agricultural chemicals suspension agent excellent performance, good dispersion, suspensibility is high, and the exhibition on plant surface is puted forth effort and adheres
Power is the strongest, resistance of rainwater washing against, and drug effect ratio is more significant and also the most lasting.The most domestic insecticides adjuvant is not the most to send out very much
Reaching, the most no small gap, the suspending agent being made into existing auxiliary agent is in terms of physical stability or many
Or the problem that few existence is certain.
Open " a kind of MTI-446 suspending agent and preparation method thereof: this disclosure of the invention of Chinese invention patent CN12239829A
A kind of dinotefuran aqueous suspension agent, by weight percentage, including following component: the former medicine of MTI-446 5% ~ 40%, suspension aid 0 ~
6%, surfactant 2% ~ 20%, thickener 0 ~ 1%, defoamer 0 ~ 1%, preservative 0 ~ 1%, antifreezing agent 0.5% ~ 5%, water complements to

Or butanol；Described preservative is formaldehyde, benzoic acid, Kathon CG or methenamine；Described antifreezing agent is ethylene glycol, glycerine, urea, different
Propyl alcohol or propane diols ".This patent preparation process does not add synergist, can only play the general effect of preparation, additionally this invention
Do not add resistance solvent and cannot prepare high-load MTI-446 suspending agent.
Summary of the invention
Present invention solves the technical problem that and be to provide a kind of MTI-446 synergy suspending agent and preparation method thereof, solve height and contain
A preparation difficult problem for amount MTI-446 suspending agent, improves the prevention effect of MTI-446 suspending agent, has economy by adding synergist
With environment double benefit.
For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of MTI-446 synergy suspending agent, by weight
Amount percentage is made up of following component: MTI-446 20%-50%, resistance solvent 2%-5%, dispersion moisture agent 5%-8%, thickener 0.1%-
1%, preservative 0.1%, antifreezing agent 3%-5%, defoamer 0.1%, synergist 2%-5%, Yu Weishui.
Further, described resistance solvent is 5# white oil；Described dispersion moisture agent is modified polycarboxylic acid salt: acrylic acid-acrylic
Acid esters-co-polymer of sulfonate, its molecular weight 30,000, each monomer mole ratio is acrylic acid: acrylate: sulfonic acid=1:3.2:0.8,；
Described thickener is xanthans and the Magnesiumaluminumsilicate mixture with arbitrary proportion；Described antifreezing agent is ethylene glycol or propane diols；Institute
Stating defoamer is organic silicon defoamer dimethicone, polyethers or n-octyl alcohol；Described preservative sodium benzoate；Described synergist is
Cocoamidopropyl betaine.
Further, the preparation process of MTI-446 synergy suspending agent is: stirring container in add amount of preparation water and
Resistance solvent, stirs, and is then sequentially added into dispersion moisture agent, thickener, preservative, antifreezing agent, defoamer, synergist and furan
The former medicine of worm amine, mixes, and 12000 revs/min carry out high speed shear 20-50 minute；Feed liquid after high speed shear carries out two grades
Sand milling, available synergy MTI-446 suspending agent.
Use and have the beneficial effects that produced by technique scheme: the present invention is compared by addition synergist and do not adds increasing
The surface tension of the MTI-446 suspending agent of effect agent reduces by 8～22 mN/m.After showing to add synergist by field experiment, desinsection is imitated
Fruit significantly improves.MTI-446 former medicine solubility in water is big, and it is 10% that the interior commonsense method of industry is only capable of making weight content
Aqueous suspension agent, is difficult to make higher amount aqueous suspension agent, and the present invention is by adding resistance solvent 5# white oil, makes the former medicine of MTI-446 exist
Solubility in water is substantially reduced, and solves the problem being difficult to prepare high-load dinotefuran aqueous suspension agent, greatly reduces production
Manufacture, artificial, packaging material, cost of transportation, improve production efficiency.MTI-446 suspending agent broad-spectrum high efficacy of the present invention, safety low-poison, rice
The crop pests such as plant hopper, cotten aphid and trialeurodes vaporariorum are efficient.

Control time: after medicine three, five, seven, 15 days
Revision insect recluced rate (%)=(residual borer population in each sky after insect population radix-spray medicine before spray medicine) * 100/ sprays insect population radix before medicine
Rectifying efficacies (%)=(treatment region Revision insect recluced rate-check plot Revision insect recluced rate) * 100/(100-check plot insect population subtracts
Move back rate)
Result of the test is as shown in table 3.
Effect experiment result table 3
。
As known from Table 3, the MTI-446 suspending agent of synergist is added apparently higher than the MTI-446 suspending agent not adding synergist
To wild cabbage trialeurodes vaporariorum prevention effect, and the MTI-446 suspending agent adding synergist Cocoamidopropyl betaine is more aqueous than adding
Azone and aqueous fatty alcohol synergist preventing and treating wild cabbage trialeurodes vaporariorum effect are remarkably reinforced.
Land for growing field crops effect experiment three:
With same method, Nanchang planthopper being carried out land for growing field crops insecticidal test, specific experiment scheme is as follows:
Medication: each sample is repeated twice
Extension rate: 20% MTI-446 SC 2000X 3000X other press content conversion multiple dilutions
Use apparatus: conventional backpack sprayer, directed spraying
Water consumption: every mu of 30 kg of water
Investigation method: use five point samplings
Control time: after medicine three, five, seven, 15 days
Revision insect recluced rate (%)=(residual borer population in each sky after insect population radix-spray medicine before spray medicine) * 100/ sprays insect population radix before medicine
Rectifying efficacies (%)=(treatment region Revision insect recluced rate-check plot Revision insect recluced rate) * 100/(100-check plot insect population subtracts
Move back rate)
Result of the test is as shown in table 4.
Effect experiment result table 4
。
As known from Table 4, the MTI-446 suspending agent of synergist is added apparently higher than the MTI-446 suspending agent not adding synergist
