Description

Composition pesticide containing pyridine quinazoline and Moroxydine Hydrochloride
Technical field
The present invention relates to a kind of composition pesticides, and specifically one kind is effective with pyridine quinazoline and Moroxydine Hydrochloride The composition pesticide of ingredient is suitable for prevention crop disease viral disease.
Background technology
The viroses of plant are often to cause heavy loss to agricultural production by the parasitogenic disease of plant virus, according to statistics, The underproduction reaches 10-30%, about 20,000,000,000 dollars of economic loss caused by annual.China is a large agricultural country, every year because of virosis pair The about tens billion of members of economic loss caused by grain-production, garden crop, industrial crops etc..Since the prevalence of virosis is led If therefore, single by by taking viruliferous insect as caused by the malicious insect vector of the biography such as aphid, leafhopper, plant hopper, aleyrodid Using the medicament of prevention virosis, control effect is not satisfactory, and the virosis that cannot fundamentally control on crops causes harm.
Pyridine quinazoline (Pyrifluquinazon), belongs to novel quinazoline quinoline insecticides, and the mechanism of action is to prevent pest Feed is mainly used for preventing Phytophthira, aleyrodid class, scale insect on the crops such as vegetables, fruit tree and tealeaves until pest is slowly died of hunger The suckings mouthpart insect such as class, leafhopper class, thrips class, can significantly reduce the propagation of viral vectors, which can be complete Penetrate blade face, to below blade face the pest of predation and perch also can reach the purposes of effective prevention and control.
Moroxydine Hydrochloride (Moroxydine hydrochloride) is the agent for prevention and control of virus of a kind of wide spectrum, low toxicity, dilution After liquid afterwards sprays application to plant leaf surface, medicament can be entered by aqueous vapor hole in plant, inhibit or destroy nucleic acid and lipoprotein Formation, prevent virus reproduction process, play the role of controlling the virus.
The present inventor has made intensive studies the compounded formula screening of pyridine quinazoline and Moroxydine Hydrochloride, unexpected Ground finds that pyridine quinazoline and Moroxydine Hydrochloride are compounded, and has within the scope of certain compound proportion significant synergistic Effect, in actual use, pyridine quinazoline and Moroxydine Hydrochloride are used in compounding the biography that can either prevent the viroses of plant Insect vector is broadcast, while can play therapeutic effect to virosis itself again, hence it is evident that improves the prevention effect to the viroses of plant Fruit completes the present invention after further study.
Invention content
The purpose of the present invention is to provide a kind of prevention viroses of plant containing pyridine quinazoline and Moroxydine Hydrochloride Composition pesticide, the composition have significant synergistic function, by prevent the viroses of plant biography poison insect vector with And the therapeutic effect to virosis itself, hence it is evident that improve the control effect to the viroses of plant.
Technical solution:A kind of composition pesticide containing pyridine quinazoline and Moroxydine Hydrochloride, active ingredient are pyridine quinoline The weight ratio of oxazoline and Moroxydine Hydrochloride, pyridine quinazoline and Moroxydine Hydrochloride is 1:1~1:20, pyridine quinazoline and hydrochloric acid Weight percent of the quinoline guanidine weight summation in composition pesticide is 1~85%, remaining uses and can connect to allow in pesticide The auxiliary element received.
The auxiliary element is solvent, emulsifier, wetting agent, dispersant, stabilizer, antifreezing agent, thickener, disintegration One or more kinds of groups in agent, binder, antifoaming agent, bleeding agent, synergist, fire retardant, density adjuster and filler It closing, the above substance is common known substance in pesticidal preparations, is varied from according to the different formulations of pesticide are prepared into, but It is not particularly limited.
Composition pesticide of the present invention can be prepared into any one dosage form used in suitable agricultural production by known method, Relatively good dosage form has suspending agent, aqueous emulsion, microemulsion, water dispersible granules, wettable powder and ultra low volume liquids.
The production technology of the various application forms of the composition pesticide belongs to existing known technology, no longer superfluous herein It states.
The frequency of administration and amount of application of composition pesticide of the present invention change with crops, pest, weather condition and have a small amount of Variation, can achieve the purpose that effectively to prevent by using dosage appropriate.
The target plant that the present invention is suitble to is rice, corn, sugarcane, rape, tobacco, peanut, soybean, tomato, capsicum, horse Bell potato, melon, wild cabbage, strawberry, lichee, longan, jujube tree, cotton, banana, Siraitia grosvenorii and forest etc..
The present invention is suitble to prevent southern rice black-streaked dwarf disease, black streaked dwarf virus of rice, rice stunt, rice Huang It is the short disease of short disease, rice gall dwarf virus disease, Rice Orange Leaf Disease, rice tooth, stripe disease, yellow stunt of wheat, wheat rosette stunt, small Wheat soil-borne mosaic, wheat yellow mosaic, wheat shuttle streak mosaic disease, wheat red stunt, wheat streak mosaic, Corn Crude contracting Disease, mosaic of sugarcane, sugarcane yellow leaf, sugarcane bacilliform virus disease, tobacco mosaic viruses disease, tobacco cucumber mosaic virus Disease, tobacco potato Y virus disease, Strawberry mottle virus disease, strawberry light yellow edge virus disease, strawberry crinkle virus disease, strawberry edge Arteries and veins virosis, peanut stripe viruses disease, peanut Cucumber Mosaic Virus, peanut stunt viral disease, peanut bud blight poison, big Tofu pudding Leaf disease viral disease, soybean alfalfa mosaic viral disease, tomato virus disease, potato virus disease, pepper virus disease, banana bunchy top disease, dragon The communication media of eye lichee witches' broom disease, Siraitia grosvenorii virosis, jujube tree jujube witches broom and virosis:Plant hopper, aphid, aleyrodid, leaf Cicada, stinkbug silk worm, scale insect, wood louse and thrips etc..
Compared with the prior art, the advantages of the present invention are as follows:
1, two kinds of active ingredients of pyridine quinazoline and Moroxydine Hydrochloride compounding has significant synergistic function, both can be with The communication media insect of the viroses of plant is prevented, while there is therapeutic effect again to virosis itself, hence it is evident that is improved to virus The control effect of disease.
2, two kinds of active ingredients of pyridine quinazoline and Moroxydine Hydrochloride are used in compounding, and reduce Pesticide use number, are reduced Use cost alleviates pollution to environment, has delayed the generation of viral resistance, increases the service life of pesticide.
