Abstract
The invention discloses a novel insecticidal suspending agent containing azadirachtin and neem oil, belonging to the technical field of pesticides, and solving the problems of bad prevention and control effects, higher and higher usage amount, as well as higher and higher prevention and control concentration of chemical pesticides, more and more obvious pesticide residue on crops, and obvious quality decline of agricultural products in the prior art. The novel insecticidal suspending agent containing azadirachtin and neem oil disclosed by the invention is composed of the following components in percentage by weight: 0.1-3% of azadirachtin, 3-10% of neem oil, 5-20% of chlorantraniliprole, 2-5% of a dispersing agent, 2-4% of a thickening agent, 3-8% of an antifreezing agent, 0.2-0.6% of a defoaming agent, 2-4% of a wetting agent, 1.2-3.8% of an antimicrobial agent, and 60-80% of water. The invention further provides a preparation method for the suspending agent aforementioned. The suspending agent disclosed by the invention is prominent in prevention and control effects on pests, capable of delaying the generation of the drug resistance of the pests, and avoiding the awkward situation of increasing the dosage of chlorantraniliprole to improve effects after long-time use of chlorantraniliprole, thus reducing residues, promoting environmental protection and improving the quality of agricultural products, and remarkable in social and economic benefits.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of new insecticidal suspending agent that contains nimbin and neem oil and preparation method thereof.
Background technology
Contain a large amount of organic solvents in the chemical pesticide, when making huge contribution for agricultural foison, also brought serious pollution to natural environment.Along with environmental regulation becomes better and approaching perfection day by day, the cry that reduces pesticide pollution is day by day strong.And at present maximum problem is that the increase of chemical pesticide resistance causes control efficiency not good on the pesticide market, and usage amount is increasing, and concentration to control is more and more higher, and effect is with poor, is widely used such as first dimension salt that resistance has increased by 30 times over 10 years; In addition, the crop residue of pesticide are more and more outstanding, and agricultural product quality and quality descend obviously, day by day increase for the danger of society's band, have a far reaching influence.
Agricultural chemicals suspension agent belongs to one of Water-borne modification novel form, is pesticide active ingredient and dispersant, wetting agent, thickener, defoamer, antifreeze etc. to be dispersed in water form a kind of high dispersive, stable suspended substance.Because agricultural chemicals suspension agent is take water as dispersion medium, make it have environmental protection, cheap characteristics, reduced simultaneously the use of a large amount of organic solvents, production process is safe, pollution-free; And suspending agent can mix with arbitrary proportion with water, and is easy to use, can reach larger coverage rate after the dilution, can be processed to the formulation of high concentration.
Nimbin is that a class is separated the strongest active compound from the seal chinaberry, and it belongs to tetracyclic triterpenes.Nimbin can be divided into nimbin-A ,-B ,-C ,-D,-E, totally 8 kinds of-F ,-G ,-I, nimbin-A is exactly the nimbin of common indication, and its mechanism of action is special, have food refusal, avoid keep away, tag, stomach toxicity, interior suction and suppress insect growth growth effect, by internationally recognized be most important antifeedant for insect.
Neem oil is that the extraction active component is formulated from neem seed, sheerly natural desinsection, bactericide, have wide spectrum, efficient, low toxicity, noresidue, pollution-free, to natural enemy disturb less, without obviously poisoning, easily degraded in environment, provincialism aboundresources, reproducible characteristics.The seal chinaberry contains plurality of active ingredients, and 200 various pests and a lot of virus are had preventive effect, and to people, fish, poultry and beneficial organism safety.
Rynaxypyr, chemical name: 3-bromo-N-[4-chloro-2-methyl-6-(methyl-carbamoyl) benzene]-1-(3-chloropyridine-2-yl)-1H-pyridine-5-formamide.Its mechanism of action is the efficient blue Buddhist nun's alkali acceptor that activates, and the calcium ion that excessively stores in the release cells causes the insect paralysis dead.The Rynaxypyr high-efficiency broad spectrum, to the Noctuidae of phosphorus wing order, Carposinidae, tortricid, miller section etc., the Culculionidae of coleoptera, Chrysomelidae, dipterous Agromyzidaes etc. all have good control effect.
At present, there are no Rynaxypyr and neem oil composite be the introduction of suspending agent.
Summary of the invention
The object of the present invention is to provide a kind of new insecticidal suspending agent that contains nimbin and neem oil and preparation method thereof, the control efficiency that solves chemical pesticide in the prior art is not good, usage amount is increasing, concentration to control is more and more higher, the crop residue of pesticide are more and more outstanding, and product quality and the quality obvious problem that descends.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of new insecticidal suspending agent that contains nimbin and neem oil is comprised of the component of following percentage by weight:
As a kind of preferred, above-mentioned suspending agent is comprised of the component of following percentage by weight: nimbin 0.3%, neem oil 5%, Rynaxypyr 10%, dispersant 3.2%, thickener 3.1%, antifreeze 5.2%, defoamer 0.38%, wetting agent 2.9%, antimicrobial 2.6% and water 67.32%.
Further, described dispersant is sodium lignin sulfonate or neopelex, thickener is xanthans or polyvinyl alcohol, antifreeze is ethylene glycol or propane diols, defoamer is polyethers-siloxanes or silicone oil, wetting agent is sodium alkyl sulfonate or sorbitol polyoxyethylene ether, and antimicrobial is benzoic acid or sorbic acid.
Above-mentioned a kind of preparation method who contains the new insecticidal suspending agent of nimbin and neem oil, specifically be that 0.1～3% nimbin, 3～10% neem oils, 5～20% Rynaxypyr, 2～5% dispersant, 2～4% thickener, 3～8% antifreeze, 0.2～0.6% defoamer, 2～4% wetting agent, 1.2～3.8% antimicrobial and 60～80% water join in the mixing kettle with percentage by weight, being stirred to material fully mixes, through ball milling, sand milling, it is the suspending agent product of 0.8～4.2 μ m that screening obtains particle diameter again.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) suspending agent of the present invention is splendid to pest controling effect, and can delay the generation of pest resistance to insecticide, thereby reduces usage amount, has reduced residue, has improved quality and the quality of crop;
(2) the present invention adopts water as medium, can not burn in preparation process, also can not produce blast, and is quite safe, also reduced simultaneously toxicity;
(3) the present invention is composite and add a certain amount of neem oil and make by nimbin and Rynaxypyr, it is more outstanding to prevent and treat on the one hand the rice-stem borer effect, adds on the other hand neem oil in the prescription and can delay rice-stem borer to the drug-fast increase of Rynaxypyr;
(4) preparation method of the present invention is simple, easy operating, and when production process, environmental pollution is minimum.
