Abstract
The invention relates to a compounded insecticidal composition which consists of an effective active component and an auxiliary component, wherein the effective active component consists of imidan and azadirachtin; and the compounded insecticidal composition comprises 4-60wt% of imidan, 0.1-2wt% of azadirachtin and 39-95wt% of the auxiliary component. According to the invention, after imidan and azadirachtin are compounded, an obvious synergistic action can be generated; and the compounded insecticidal composition can be used for effectively delaying the resistance generation of insect pests, effectively prolonging the variety service lives of farm chemicals, reducing the application quantity of the farm chemicals and lowering the field application costs of the farm chemicals, and is safe for human and livestock as well as current-reap crops and afterreap crops. Farmland experiments indicate that the compounded insecticidal composition has obvious prevention and treatment effects on the cabbage worms, plant louse and plutella xylostella which are positioned on vegetables, the cotton bollworms, plant louse and caro which are positioned on cotton, citrus icerya purchasi, soybean pod borer and the like; and the compounded insecticidal composition has stable dosage form property, good low-temperature stability and good heat storage stability, and meets the industry standard.
Description
Technical field
The invention belongs to and relate to insecticide, the complex insecticidal composition of particularly a kind of phosmet and vegetable source pesticide active ingredient nimbin.
Background technology
Pollution-free vegetable and tealeaves and mulberry tree, traditional Chinese medicine etc. are the main economic crops of China, receive the harm of multiple pest in its process of growth.Sometimes various pests takes place simultaneously, and particularly, Bemisia tabaci, cabbage caterpillar, mulberry geometrid (Hemerophila atrilineata), tea lesser leafhopper caused disaster in China's some areas outburst in recent years.In this case, can not satisfy market when in time supplying like higher effective and lower toxic pesticide, the peasant can only abuse the high-toxic pesticide emergence control; Though short-term inner control insect, destroyed ecology, injured health of human body; Influenced the outlet of agricultural product, brought great loss to agricultural production.Therefore, a kind of high-efficiency low-toxicity Pesticidal combination of design innovation is that the prevention high-toxic pesticide pollutes one of effective way of agricultural product to satisfy market in urgent need.
Phosmet, chemical name: 0,0-dimethyl-S-(phthalimide ylmethyl) phosphorodithioate, molecular formula: C

2, be a kind of organic phosphates broad spectrum disinfestation, miticide, have and tag and stomach poison function.Its mechanism of action is the cholinesterase that suppresses in the insect bodies, is applicable to various pests such as control paddy rice, cotton, fruit tree, vegetables.Phosmet is a kind of more common chemical pesticide, because the field sprays for a long time, causes dosage and concentration to improve constantly, and has increased the control cost.
Nimbin is a kind of compound from plant seal chinaberry, has good insecticidal activity, and is almost all effective to all pest; Consumption is low, and degraded does not very soon injure natural enemy and other non-target organism in environment; Be a kind of universally acknowledged biological insecticides, its shortcoming is unstable.
Summary of the invention
The object of the present invention is to provide a kind of complex insecticidal composition; Its composition comprises phosmet and nimbin; This complex insecticidal composition can overcome pest resistance to insecticide; Enlarge insecticidal spectrum, reduce dosage, thereby it is big to solve present phosmet pest control dosage, cost is high, repeated use is prone to produce technical problems such as resistance.
For addressing the above problem; The technical scheme that the present invention adopted is: a kind of complex insecticidal composition; Said composition is made up of effective active component and helper component, and said effective active component is made up of phosmet and nimbin, and the percentage by weight of phosmet is 4～60% in this complex insecticidal composition; The percentage by weight of nimbin is 0.1～2%, and the percentage by weight of auxiliary element is 39～95%.Phosmet and nimbin are 100% in former medicine purity; Promptly in the weight of pure phosmet and nimbin contained in the commercial commodity (down with); Other is in industrial products weight (down together), and wherein this complex insecticidal composition can be divided into missible oil formulation and wettable powder formulation according to formulation.
Be directed to the missible oil formulation:
Said auxiliary element comprises No. 1600 emulsifier of farming breast and solvent, and the percentage by weight that No. 1600 emulsifier of its middle peasant's breast account for said complex insecticidal composition is 5～20%, and the percentage by weight that solvent accounts for said complex insecticidal composition is 34～75%.
As preferably, in this complex insecticidal composition, the percentage by weight of phosmet is 15～50%, and the percentage by weight of nimbin is 1～2%, and the percentage by weight of No. 1600 emulsifier of farming breast is 9～15%, and the percentage by weight of solvent is 40～70%.
Wherein, said solvent is selected from toluene, xylol, methyl alcohol, dimethyl sulfoxide (DMSO).
Be directed to the wettable powder formulation:
Said auxiliary element comprises following component: di-2-ethylhexylphosphine oxide bitter edible plant sodium sulfonate, neopelex, AEO; White carbon, precipitated calcium carbonate, No. 1600 emulsifier of farming breast; Di-2-ethylhexylphosphine oxide bitter edible plant sodium sulfonate 4%～8% wherein, neopelex 1%～4%, AEO 1%～2%; White carbon 9.5%～15%, precipitated calcium carbonate 18%～33%, No. 1600 emulsifier 5%～20% of farming breast; Potter's clay 0.5～13%, this percentage are its percentage by weight that accounts for said complex insecticidal composition.
In component of the present invention: the commodity of AEO are called the JFC bleeding agent; Under catalytic action, become high molecular polyether by higher aliphatic (like laruyl alcohol), through bleaching with ethylene oxide polymerization; A kind of auxiliary agent that filtration forms, it has good permeability and wetability.
Di-2-ethylhexylphosphine oxide bitter edible plant sodium sulfonate, the trade name dispersing agent NNO has superior proliferating property and protecting colloid performance.
White carbon is a hydrated SiO 2, absorbs dispersant as phosmet in the present invention.
Precipitated calcium carbonate is in the present invention as functional filler and reinforcing agent.
The chemical name that No. 1600, the farming breast is a styryl phenol polyoxy ethyl polyoxyethyl propyl ether, and it is good to have emulsion stability, and good fluidity adapts to advantages such as water temperature, water quality wide ranges, is highly suitable for the composite of phosmet emulsifier.
Characteristics such as the present invention has efficiently, wide spectrum, safety, consumption are few.The present invention with phosmet and nimbin carry out composite after, produce obvious synergistic effect.Can effectively alleviate the generation of pest resistance, prolong pesticide species service life, and reduce dosage, reduce agricultural chemicals field application cost, to people and animals and when stubble and succession crop safety.The farmland experiment shows: the present invention is to vegetables cabbage caterpillar, aphid, diamond-back moth; Cotton bollworm on the cotton, aphid, acarid, and oranges and tangerines coccid, soybean pod borer etc. have tangible control efficiency.Formulation stable in properties after it is composite, and low-temperature stability and heat storage stability are good, meet industry standard.
