Description
Technical field
The present invention relates to pesticidal preparations and preparation method field, be specifically related to one and relate to Acetamiprid and emamectin benzoate mixture sol particle insecticide and preparation method thereof.
Background technology
Emamectin benzoate (Emamectin Benzoate) full name is emamectin-benzoate, emamectin benzoate is a kind of never poison, its mechanism acts on insect neuron cynapse or neuromuscular synapse acceptor, the information transmission of nerve endings in interference insect body, namely excites nerve endings to release neurotransmission inhibitor γ mono-aminobutyric acid.Impel chloride channel to extend open, have activation to chloride channel, a large amount of chlorion pours in and causes neural membrane potentials hyperpolarization, causes neu to be in holddown.Thus contacting of block nerves tip and muscle, make insect paralysis, food refusal, death.Because its mechanism of action is unique, so with conventional medicament without cross resistance.
Acetamiprid (Acetamiprid) belongs to Nitromethylene heterocycle compound, is a kind of novel pesticide.Act on the nAChR of insect nerve system synapses, the neural stimulation conduction of interference insect, causes nervous system path blockade, causes neurotransmitter acetylcholine in the accumulation of synapses, thus cause insect paralysis, finally dead.Because Acetamiprid mechanism of action is unique, to organic phosphor, carbamate, and the insect that the pesticide species such as pyrethroid develops immunity to drugs has better effects.Acetamiprid have tag, stomach toxicity and stronger osmosis, consumption is few, activity is high, insecticidal spectrum is wide, the lasting period reaches about 20 days, to features such as Environmental compatibility are good.
What Chinese patent CN102550586A disclosed a kind of binary composition be made up of emamectin benzoate and Acetamiprid flies anti-medicine dedicated.Its main component is made up of emamectin benzoate and Acetamiprid, and is processed into specific formulation, can be suspending agent, wetting powder or microemulsion.Be suitable for the generation of the mode disease and pest control that aircraft spreads pesticides.But, suspending agent technique difficulty controls and cost is high, wetting powder easily causes dust pollution, the remaining toxicity of missible oil and microemulsion formulation is large and cause its expense of raw materials high due to it containing organic solvent, the cost of preparation is also high, bottled because adopting again, so the expense of packaging, transport, keeping is also high.
At present, the emamectin benzoate product that domestic and international pesticide market is applied, all based on emamectin benzoate missible oil, manufactures soluble granule to emamectin benzoate and Acetamiprid mixture and brings difficulty.Chinese patent CN102550586A does not mention soluble granule only, also illustrate that the difficulty of processing of soluble granule from the side.
Summary of the invention
The object of the present invention is to provide low, the eco-friendly Acetamiprid of a kind of high-efficiency low-toxicity, cost and emamectin benzoate mixture disinsection soluble granules novel form, the preparation method of described Acetamiprid and emamectin benzoate mixture disinsection soluble granules is provided simultaneously.
The present invention adopts following technical scheme:
A kind of Acetamiprid and emamectin benzoate mixture sol particle insecticide, it comprises each component of following percentage by weight: in former medicine, the filler of Acetamiprid 5 ~ 50%, emamectin benzoate 1 ~ 20%, dispersant 5 ~ 13%, wetting agent 2 ~ 7%, stabilizing agent 1 ~ 3%, defoamer 0.5 ~ 1% and surplus.
Wherein, described dispersant is one or more in sodium lignin sulfonate, Negel formaldehyde condensation products, acrylic acid maleic acid, fatty alcohol-polyoxyethylene ether or aliphatic alcohol sodium sulfate.

Wherein, described filler is one or more in sodium citrate, soluble starch, Lactis Anhydrous or anhydrous sodium sulfate.
The present invention also comprises a kind of Acetamiprid and emamectin benzoate mixture sol particle method for producing insecticide, and it comprises the steps:
1) Acetamiprid, emamectin benzoate, dispersant, wetting agent, stabilizing agent, defoamer and filler are carried out coarse crushing;
2) each component after coarse crushing is uniformly mixed, carries out Ultrafine Jet Milling, obtain the superfine powder opisthosoma of particle diameter less than 15 microns;
3) mediate after adding ethanol or methyl alcohol in superfine powder opisthosoma, then through extruder grain;
4) obtained thick product after particle drying step 3) obtained;
5) thick product obtains soluble granule product after screening.
In preparation method, the addition of described ethanol or methyl alcohol is 7% ~ 10% of superfine powder opisthosoma gross mass.
In preparation method, described dry run is vacuum drying.
In preparation method, described vacuum drying temperature is 55 ~ 65 DEG C, and the time is 1 ~ 2 hour.
Beneficial effect of the present invention is:
(1) Acetamiprid and emamectin benzoate mixture use by the present invention, work in coordination with and play a role, and compensate for self deficiency of single dose agricultural chemicals, remarkable to control efficiency such as cotten aphid, vegetable aphid, peach fruit borer.
(2) soluble granule of the present invention is a kind of eco-friendly pesticide species, which overcomes suspending agent, wetting powder or missible oil formulation and there is dust pollution and the shortcoming such as the remaining toxicity of cream preparation is large and cost of transportation is high.
(3) The present invention gives formula and the preparation method of emamectin benzoate and pyridine worm miaow binary built soluble granule, by the improvement of formula, and coordinate the method for its kneading and extruder grain to carry out granulation, compared to traditional dry suspending agent prilling process, its process equipment is simple and easy and cost is low.
