Abstract

The invention discloses a composite insecticidal composition containing pymetrozine and propylene glycol alginate and the application thereof. The insecticidal composition uses pymetrozine and propylene glycol alginate as main active ingredients, wherein the weight ratio of the pymetrozine to the propylene glycol alginate is 0.1-80 to 0.1-60. The insecticidal composition can generate higher synergy, overcome and delay the drug resistance of pests, expand the prevention spectrum, have high desinsection speed, decrease the drug cost and lessen the toxicity. The insecticidal composition can prevent hemiptera pests on crops and particularly can be used for preventing paddy delphacidae and wheat aphids, and the effect of the insecticidal composition is significantly higher than that of single agent.

Description

A kind of compound pesticide compositions that contains pyrrole aphid ketone and propylene glycol alginate and uses thereof
Technical field
The invention belongs to pesticide field, being specifically related to a kind of is compound pesticide compositions of main active ingredient and uses thereof with pyrrole aphid ketone and propylene glycol alginate.
Background technology
Pyrrole aphid ketone (pymetrozine), chemical name: (E)-4,5-dihydro-6-methyl-4-(3-pyridine methylene amino)-1,2,4-triazine-3 (2H)-ketone.Being Switzerland Novartis Co.,Ltd eliminates aphis and the new type heterocycle class insecticidal materials of aleyrodid in exploitation in 1988 anti-, has efficient, low toxicity, high selectivity, characteristics such as environmentally friendly.Its mode of action uniqueness: mainly be the feed behavior that influences insect, make its food refusal and dead.This medicine is all effective to larva and adult, and its energy rapid osmotic is in plant leaf blade, and the longevity of residure reached more than one month, and did not have any cross resistance, to the natural enemies security height.Pyrrole aphid ketone is all effective to larva or adult, and this medicine can be penetrated in the plant leaf blade very soon, and residual effect reaches one month, because no cross resistance, to the natural enemy high safety, very suitable resistant insect control.Pyrrole aphid ketone has very high preventive effect to aphid, plant hopper, leafhopper, aleyrodid, the Chinese toon rubber of crops such as paddy rice, vegetables, cotton, wheat, fruit tree.This medicine is splendid to Semiptera insect selectivity, and the selectivity of aphid is better than best anti-aphid agent-Aphox at present, and this medicine also has good interior absorption, and its systemic activity is 2～3 times of Aphox, is more than 143 times of cypermethrin.The acute oral LD of its former medicine 50Be 5820mg/kg, acute through skin LD 50(24h)＞2000mg/kg.Along with the whole world is more and more paid attention to environmental protection, low toxicity, demand efficient, eco-friendly insecticidal materials increase year by year, high poison, high residue, to ecotope, and its exploitation has good prospect, will bring huge social benefit and economic benefit.But its market price is higher.
Propylene glycol alginate gets Main Ingredients and Appearance by the marine algae extract alginic acid through esterification: its part carboxyl of alginate esters class is by the propane diols esterification.It is a kind of Biocidal medicine of physical action mechanism, and the mode of action is for tagging, and with its distinctive viscosity and tagging property of physics, sealing or obstruction insect are blocked metabolism and the circulation canal of insect in order to the pore of respiratory metabolism fast, and it is dead that it is suffocated.It has lethal effect to small-sized soft-bodied insects, can prevent and treat adult and the larva of insects such as trialeurodes vaporariorum, rice fulgorid, Bemisia tabaci, small brown rice planthopper, pear sucker, leafhopper, tetranychid effectively.The propylene glycol alginate edible at home and abroad is widely used in the food service industry as food additives, and is all harmless to people and environment, slight to the influence of insect pollinator and natural enemy, belongs to the low toxicity insecticidal materials.
Pyrrole aphid ketone is to inhale infiltrative acetylcholinesteraseinhibitors inhibitors in having, and propylene glycol alginate is typical physics contact insecticide, the inventor finds that both are composite and can improve insecticidal effect, enlarge insecticidal spectrum, improve the quick-acting of medicament, reduce dosage, alleviate the medicament selection pressure, the generation of delaying drug resistance and development.
Summary of the invention
The purpose of this invention is to provide a kind of compound pesticide compositions that contains pyrrole aphid ketone and propylene glycol alginate.
Another object of the present invention provides a kind of this compound pesticide compositions and prevents and treats application on the insecticidal materials of resistance Semiptera insect in preparation.
For achieving the above object, pyrrole aphid ketone and propylene glycol alginate that the present invention will grow the lasting period are composite, obtain the present invention's multifunctional insecticide composition efficiently.This insecticidal materials has good preventive effect to the various pests that rice fulgorid and wheat aphid are easy to generate resistance; And the inhibition insect is to the pesticide resistance generation of pyrrole aphid ketone.
The present invention is by following scheme implementation:
A kind of compound pesticide compositions that contains pyrrole aphid ketone and propylene glycol alginate is characterized in that it contains pyrrole aphid ketone and propylene glycol alginate is main active ingredient, and wherein, the weight ratio of pyrrole aphid ketone and alginic acid malonic acid alcohol ester is 0.1～80: 0.1～60.The effective ingredient of above-mentioned desinsection combination is present in the composition with the synergy effective dose.
The weight ratio preferred 1～60: 0.5～30 of pyrrole aphid ketone and alginic acid malonic acid alcohol ester in this Synergistic insecticidal compositions, the best is 5～40: 0.5～20.
In the present composition, the two percentage by weight that accounts for composition of pyrrole aphid ketone and alginic acid malonic acid alcohol ester is 1～80%.Be preferably 5～50%, most preferably 5～30%.
Above-mentioned desinsection combination is that main active ingredient (active component) and insecticides adjuvant, excipients are mixed with any one formulation that allows on the agricultural chemicals with pyrrole aphid ketone and propylene glycol alginate.The preferred pulvis of described formulation, wetting powder, aqueous emulsion, suspending agent, microemulsion, missible oil and water dispersion granule.Described auxiliary agent can adopt calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxy third rare block compound (as farming breast 33 #, farming breast 1601 #), the one or more combinations in the polyoxyethylene nonylphenol ether, excipient comprises cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient can be singly with or and also can add other auxiliary material with reaching.
Above-mentioned Pesticidal combination is prevented and treated the application on the insecticidal materials of resistance Semiptera insect in preparation, especially use on the insecticidal materials of preparation control water rice hopper, aleyrodid and wheat aphid.
Pesticidal combination of the present invention has following beneficial effect: (1) is compared with single agent, and said composition has notable synergistic to insect, has obviously improved control efficiency; (2) alternative high-toxic pesticide, and reduce the field dosage significantly, effectively reduce environmental pollution and residue of pesticide; (3) have concurrently quick-acting and long-acting; (4) compare with the agent of pyrrole aphid ketone list, produce and the use cost reduction; (5) suppress the resistance enhancing of insect to agricultural chemicals.
