Description
Technical field
The invention belongs to pesticide field, and in particular to a kind of metaflumizone oil-suspending agent.
Background technology
At present, industrial crops insect is prevented and treated in agricultural planting and generally uses conventional spray-on process.Conventional spray-on process is by agricultural chemicals
Preparation is diluted with water certain concentration, and Target crops or evil thing are sprayed with conventional nebulizers (including manual and power spraye)
Mist prevents and treats the method for pest and disease damage.Some defects be present in this application method：
(1) conventional spray-on process pharmacy effect is poor.Because conventional spray-on process using the formulation of medicament is usually missible oil, water
Agent, wettable powder, suspending agent, aqueous emulsion etc., certain defect on be present, causing preventive effect poor.On the one hand, due to adding
Enter a large amount of water dilutions, the concentration of decoction is very low, and surface tension is often larger, viscous on having the crop or target surface of wax coat
Attached property, wetability, permeability are poor, it is difficult into crop and target body；On the other hand, illumination, high temperature, drying nature
In environment, the water in decoction is easy to evaporate, and causes medicament to remain in crop surface, easy photodissociation, and decoction dry after by
Easily come off and fail from crop in poor adhesion；3rd, the mist droplet particle size routinely sprayed is larger, up to 200~600 μm, leads
The decoction for causing to be sprayed onto on crop or target surface is easily because poor adhesion is lost in；4th, conventional spraying droplet, which is difficult to reach, to be made
Inside thing leaf back and crown canopy, medicament is caused can not effectively to contact harmful thing and work.
(2) conventional spray-on process labor intensity is high, and work efficiency is low.Labor intensity is big, and generally work efficiency is only 2~5 mus/day per capita,
It is difficult to the needs for meeting large-scale planting.
(3) conventional spray-on process preventing and treating pest and disease damage needs a large amount of water dilution medicaments, and usual water consumption is up to 450~900L/hm2,
In drought and water-scarce area, the difficult restraining factors for turning into the prevention and control of plant diseases, pest control of water intaking.
(4) agricultural production is seasonal obvious, and pest and disease damage is often in short time outburst, it is necessary to which a large amount of manpowers are prevented and treated, often
Rule spray-on process requirement has substantial amounts of labour to complete dispenser.
Metaflumizone, English name：metaflumizone；Molecular formula：C24H16F6N4O2；Chemical name：(E+Z)-2-
[2- (4- cyano group benzene) -1- (3- trifluoromethylbenzenes) ethylidene]-N- (4- trifluomethoxybenzenes) hydrazine carbonyl oxamides；Structural formula：
Metaflumizone, belong to semicarbazones insecticides.Metaflumizone has insecticidal activity in itself, it is not necessary to which biology swashs
It is living, with existing each insecticides no interactions resistance.By being attached on the acceptor of sodium-ion channel, sodium ion is hindered to pass through,
With chrysanthemum esters or other kinds of compound no interactions resistance.The medicine mainly enters it by pests and stomach toxicity occurs in vivo
Kill off the insect pests, action of contace poison is smaller, no systemic action.The medicine has preferable preventing and treating for the target pest of each age, larva
Effect, the medicine enters polypide after insect's food-taking, passes through unique mechanism of action and blocks sodium ion in sodium-ion channel on insect neuron axon film
Passage, prevent sodium ion from by axolemma, and then suppressing nerve impulse makes polypide is excessive to loosen, and benumbs, after several hours,
Insect is to stop feeding, dead in 1~3d.Metaflumizone can penetrate the cuticula of dicotyledon and thin with medium speed
Piece tissue, about half are trapped in the wax coat (cutin) of epicuticle or epidermis, and it is bright that this shows that the medicament is not shown
Aobvious more layer motion.Analysis of experiments shows that metaflumizone will not be transmitted to the other parts of plant from treated blade, does not also have
Shown at the settlement point of blade significantly to ambient radiation diffusion motion.Therefore metaflumizone only has medium in blade surface
Osmotically active, in the chlorenchyma of plant and root without uptake and translocation.
Metaflumizone can effectively prevent and treat larva, the adult of various regions lepidoptera pest and some coleopteras, can also use
In insects such as preventing and treating ant, termite, flies, cicada dung beetles.Active component metaflumizone, formulation on the market is mainly suspending agent at present
SC, bulky grain agent GB, wettable powder WP, or spread fertilizer over the fields by physics, such as GB, or by being watered spray pesticide after dilution.And cyanogen
There is not been reported both at home and abroad for the oil-suspending agent of fluorine worm hydrazone, the pesticidal preparations for also having oiliness decentralized medium without report, such as missible oil,
Do not report that use can be used for the pesticidal preparations for the metaflumizone that hot mist machine is applied.
The content of the invention
In view of this, it is an object of the invention to overcome, work efficiency present on conventional spray techniques prevention and controls is low, works
The defects of intensity is big, water requirement is big and current oil-suspending agent product resistance is strong.I.e. the first object of the present invention is to provide one kind
Metaflumizone oil-suspending agent, including following components：Metaflumizone 2%~40% by weight, auxiliary agent 2%~25%, oiliness
