Description
Technical field
The invention belongs to pesticide fields, and in particular to a kind of fosthiazate granule and preparation method thereof.
Background technique
Fosthiazate is a kind of efficient, wide spectrum organic phosphorus nematicide of non-fumigation type of Japanese Ishihara Sangyo Kaisha Ltd.'s exploitation.
Its mechanism of action is the acetylcholinesterase for inhibiting pest, not only has very strong action of contace poison, but also be also easy in plant
Middle Uptake and translocation especially has apparent control efficiency to root-knot nematode and pratylenchus etc..But there is easily decomposition in fosthiazate
The problem of, cause the lasting period of fosthiazate shorter.
As a kind of more satisfactory nematicidal medicament, fosthiazate half-life period in soil of the pH less than 6 is 53.3-57.7
It, half-life period is only 14.1-20.7 days in soil of the pH greater than 7.Physio-biochemical characteristics based on fosthiazate, the quotient of fosthiazate
Product preparation is mostly to be prepared into granule under the working condition of pH4.5.
However in practical applications, due to various regions soil acidity or alkalinity difference, the degradation of fosthiazate granule is shown greatly
Difference, the influence generated in face of Different climate to the nematode growth period are existing due to degradation quickening and the postponement in nematode growth period
Having fosthiazate granule field rotating medicine, even there are entirely ineffective risks, also result in serious threat to environment.
Organic phosphates chemical pesticide has long usage history, and protecting to produce to world food played an important role, but
Application for a long time causes serious environmental problem and target resistance.As international community is to the pass of ball ecological environment
Note, organic phosphates chemical pesticide product is by limiting the use of on a large scale, disable.
The problem of based on chemical pesticide use process and policy pressure, research and development are efficient, the pesticide of controlled release is new
Dosage form improves applications of pesticide mode and has important practical significance.
Summary of the invention
The object of the present invention is to provide a kind of fosthiazate granules and preparation method thereof.
Fosthiazate granule provided by the present invention is made: effective component, stable elements of the raw material for including following components
C, carrier and auxiliary material.
In the fosthiazate granule, the mass percentage content of each component can are as follows: effective component 0.1-20%, stablize at
Dividing C 0.1-10%, surplus is carrier and auxiliary material.
The stable elements C can are as follows: magnesia citrate and one or more of paraffin, alditol, sulphur ammonium (ammonium sulfate)
Mixture.
Wherein, magnesia citrate is the complex that magnesia and citric acid are formed with mass ratio 3:7-4:6.
The mass ratio of magnesia citrate and one or more of paraffin, alditol, sulphur ammonium (ammonium sulfate) can are as follows: 5:1-
2.5, concretely 3.5:1.5,5:1 or 5:1.3.
In the present invention, the dosage of the stability ingredient C is not particularly limited, but according to the change for having fosthiazate dosage
Change, on the basis of the total amount of granule, usually in 0.1-10%.
The carrier can are as follows: one or more of silica, mica, talcum, clay, kaolinite, calcium carbonate, carclazyte.
Particularly, in the present invention it is possible to be used for fertilizer as carrier in the preparation of granule.
The fertilizer can are as follows: one of nitrogenous fertilizer, potash fertilizer, phosphate fertilizer, compound fertilizer, compound fertilizer, organic fertilizer, microorganism fertilizer are several
Kind.
In the present invention, according to the difference of manufacturing process, often need to be added various auxiliary material raw materials.The auxiliary material at
Divide and be not particularly limited, but generally include: adhesive helps disintegrating agent, dispersing agent, adsorbent, lubricant, diluent, coloring
One or more of agent.

In the fosthiazate granule, the mass ratio of fosthiazate and other pesticide activity components can be 1:1-1:50.
In the present invention, the method for preparing fosthiazate granule is not particularly limited, by taking typical comminution granulation as an example,
After carrier crushes, fosthiazate sterling or industrial substance, stability ingredient C and adhesive are infiltrated into carrier surface, then pass through absorption
Agent is coated, this fosthiazate granule is obtained；Or preheat smashed carrier, it is added the adhesive of molten condition, then plus
Enter fosthiazate raw medicine and stability ingredient C, adds powdered adsorbent and fosthiazate granule of the present invention is made.
Application of the above-mentioned fosthiazate granule in prevention and treatment root-knot nematode, pratylenchus also belongs to protection model of the invention
It encloses.
The present invention is studied for environmental problem caused by target drug resistance, stability to degradation and fosthiazate, is provided
A kind of more stable process for producing granula is added nicotinic insecticide in concurrent fosthiazate now and not only shows well
Insecticidal effect, be substantially improved in the soil regime stability inferior of different condition, while reducing effective component amount of application, to work
Object and environment are safer.
