Description
Technical field
The present invention relates to a kind of herbicides with insecticidal action and preparation method thereof, belong to technical field of pesticide.
Background technology
As a kind of broad-spectrum herbicide of dosage maximum, glyphosate is current herbicide most common in the world.Glyphosate
For inner-adsorption conduction-type herbicide, each position of subterraneous root, stem is transmitted under after absorbing liquid by the cauline leaf of plant, list can be prevented and kill off
The plant of cotyledon and dicotyledonous, annual and perennial, draft and shrub etc. section more than 40.Glyphosate be manured into soil after quickly with soil
Metal ion in earth with reference to and lose activity, therefore have no adverse effects to the seed in soil and microorganism.
In agriculture weeding practice, agricultural cost can be reduced using glyphosate in large quantities, improves crop yield.However,
With a large amount of, the long-term use of glyphosate, weeds can show certain resistance, and China's glyphosate-resistant weeds mainly have meadow pine
(Drilgrass), Leersia Sw (trip grass), field bindweed, ear-piercing dish, Horseweed Herb, bamboo grass, youngia japonica etc., their throughout the country anti-
Property horizontal performance differ.The appearance of Weed Resistance and wax, the cilium on weeds surface etc. reduce absorption of the weeds to glyphosate
Related, most importantly since some areas are long-term, single use Gyphosate herbicice, resistance glyphosate Weed Resistance increases, and by
Gradually become dominant population.
It in addition, glyphosate belongs to organic phosphates steriland herbicide, kills except speed is relatively slow, the latter all weeds of general medicine
Just show intoxication, show as that blade is withered and yellow, and rear browning is withered, and at present herbicide to the insect pest of crops also without anti-
Effect is controlled, effect is single.
The content of the invention
In order to solve technical problem existing in the prior art, the object of the present invention is to provide a kind of removing with insecticidal action
Careless agent and preparation method thereof, the technical solution that the present invention takes are as follows：
A kind of herbicide with insecticidal action, is counted, raw material includes in parts by weight：
75-79 parts of glyphosate technicals, 45-48 parts of liquefied ammonia, 14-16 parts of parts of auxiliary agent, 26-28 parts of ammonium sulfate.
The glyphosate technicals, grain diameter cross 85 mesh sieves；
The liquefied ammonia, purity 96-97%；
The glyphosate technicals, active constituent content 93-94%；
The auxiliary agent includes following material component：1.2-1.5 parts of amarogentin, 0.45-0.5 parts of chitosan oligosaccharide, big mpd polypeptide 0.23-
0.25 part, 3.6-4.2 parts of essential wind oil, 1.8-2.3 parts of ursolic acid, 8-10 parts of 85% ethyl alcohol, 1.5-1.7 parts of nekal.
The chitosan oligosaccharide, deacetylation 95-97%, protein content 0.05-0.08%；
The big mpd polypeptide, protein content 85-89%, content of peptides 80-83%；
The nekal, 1% pH value of water solution are 8.1-8.3；
The essential wind oil, Determination of menthol 25-27%, camphor content 5-8%.
A kind of preparation method of the herbicide with insecticidal action, comprises the following steps：
Step 1 material addition step
According to formula, glyphosate and ammonium sulfate are weighed, first throws glyphosate and ammonium sulfate, stirring is then turned on and adds water, amount of water
For glyphosate and the 7%-8% of ammonium sulfate gross mass.
It dodges quick-fried：Glyphosate after stirring and ammonium sulfate are mixed to be sent into and dodge quick-fried device, dodge quick-fried；It is described to dodge quick-fried device；
Quick-fried point of the sudden strain of a muscle is once dodged quick-fried and dodged twice quick-fried；Described once to dodge quick-fried, it is 1.6-1.9Mpa to dodge detonation pressure power, and the pressure holding time is
9-12min；By once dodge it is quick-fried after, the gap between glyphosate and ammonium sulfate becomes larger,
The secondary sudden strain of a muscle is quick-fried, and it is 2.6-2.9Mpa to dodge detonation pressure power, and the pressure holding time is 10-14min；After secondary sudden strain of a muscle is quick-fried,
Due to dodging the unexpected increase of detonation pressure power, direct glyphosate technicals and the increase of ammonium sulfate surface area, the anti-of glyphosate is increased substantially
Answer area so that the mixed material of glyphosate and ammonium sulfate subsequently in liquefied ammonia reaction process, will not be because of the addition of liquefied ammonia
Quantitative change is few, generates and reacts incomplete technological deficiency.
Meanwhile in the prior art, glyphosate and ammonium sulfate are fed intake during mixing in material preparation step, because sulfuric acid
Ammonium easily lumps, and causes glyphosate and ammonium sulfate mixing uneven, directly reduces the reaction speed of glyphosate and liquefied ammonia, sulfuric acid
Ammonium during the reaction, blocks the progress of reaction；And by it is secondary dodge it is quick-fried after, the increase of the surface area of ammonium sulfate, simultaneously because
Ammonium sulfate has hydrophily in itself, and therefore, in the present invention, ammonium sulfate becomes water guide agent, improves the anti-of glyphosate and liquefied ammonia
It should be able to power and reaction speed.
Liquefied ammonia step is added dropwise in step 2
According to the parts by weight of formula, liquefied ammonia, liquefied ammonia is taken to require to keep the sealing of reaction vessel during being added dropwise, and is stirred；Liquid
Ammonia atomization is added dropwise, and atomization is more uniform better；Drop rate 2.3-2.8kg/min is preferably 2.5 kg/min；Object in reaction vessel
Material temperature degree is 70-73 DEG C；Material reaction pressure 0.08-0.1MPa.
Step 3 keeps the temperature kneading step
After being added dropwise to complete liquefied ammonia, heat preservation kneading is carried out at 83-89 DEG C, is preferably 85 DEG C；It is 0.06- that pressure is mediated in heat preservation
0.08；Keep the temperature kneading time 14-16min.
Step is controlled in step 4
Control ph is 3.7-4.1 after heat preservation.
Step 5 auxiliary agent adds step
Auxiliary agent is weighed according to formula, auxiliary agent is added in after the completion of heat preservation kneading step, addition manner no requirement (NR) mixes after adding in auxiliary agent
48-51min obtains mixed material.
Step 6 granulation step
By step（5）The material, be put into kneader, starts stirring, in the case where maintaining to stir, slowly to mixing
Suitable quantity of water is uniformly sprayed into material, is added according to the moist degree of material, the control of general addition in 6-7%, make mixed material into
For humidity and without the material of apparent agglomerate, material is added in comminutor and is granulated, is granulated frequency 52-56Hz, prilling temperature
82-84℃。
Step 7 baking step
Molding sol particle is dried, 82-84 DEG C of drying temperature.
Step 8 screening step
Particle after drying is sieved, adjustable screen diameter, upper strata is 8 mesh screens, and lower floor is 20 mesh screens, can be made not
With the granular herbicidal agent of the easily biological-degradable of grain size.
Compared with prior art, beneficial effects of the present invention are as follows：
1st, the herbicide prepared using the present invention, plays an important role of to kill bollworm；
2nd, the herbicide prepared using the present invention, using GB/T 28136-2011《Pesticide water-insoluble assay method》Detection
