Abstract
The invention discloses a pesticide containing hexaflumuron and malathion, which adopts hexaflumuron and malathion as effective ingredients with the weight ratio of 2 to 10:5 to 40. The pesticide of the invention combines the hexaflumuron and the malathion together so as to fully exert the respective advantages, the combination of the two types of emamectin benzoate and malathion has obvious synergy effect and can achieve the effects of enhancing preventive and control effects and delaying the drug resistance, therefore, the pesticide can be applied to prevent and control the pests of plant bug, cotton bollworm and the like.
Description
Technical field
The present invention relates to a kind of insecticide that contains fluorine bell urea and malathion and uses thereof, belong to pesticide field.
Background technology
The fleahopper silk worm comprises that green plant bug Apolygus lucorum, black striped plant bug Adelphocorissuturalis, alfalfa plant bug Adelphocoris lineolatus and adelphocoris taeniophorus Adelphocorisfasciaticollis etc. are the important pests of cotton of causing harm.It is a lot of to produce at present the medicament kind that goes up control fleahopper silk worm, for example Imidacloprid, cypermethrin, chlopyrifos, fluorine worm nitrile etc., and the problem that exists at present is; Because long-term single drug; The fleahopper silk worm has produced pesticide resistance to some medicaments, and control efficiency reduces, and must strengthen consumption in the production and could control its generation and cause harm; A large amount of chemical insecticides is sprayed onto in crop and the farmland, has caused the pollution to cotton product and environment.Therefore, be badly in need of pesticide new variety efficient, environment-friendly type in the production.
Fluorine bell urea (hexaflumuron) belongs to the benzoyl urea insecticide, is chitin synthesis inhibitor, has very high desinsection and ovicidal activity, can be used for cotton and fruit tree and prevents and treats multiple coleoptera, diptera, Homoptera insect.Be characterized in toxicity low, to person poultry safety, effective to various pests, insect is planted by the Zhiduo County of can holding concurrently.
Malathion (malathion) has another name called marathon, is one of representative kind of organophosphorous pesticide, insect is had tag, stomach toxicity and fumigation action.Be characterized in that toxicity is low, low price, action spectrum be wide, all effective to most insects, mite, insect is planted by the Zhiduo County of can holding concurrently simultaneously.Its shortcoming is that dosage is bigger.
Therefore, the researcher is devoted to study a kind of insecticide at present, can not only improve drug effect, reduces cost, and can avoid and delay the pesticide resistance generation.
Summary of the invention
The purpose of this invention is to provide a kind of insecticide that contains fluorine bell urea and malathion; The two is combined the advantage that can give full play to separately; And the combination of two kinds of active ingredients has significant synergies, and can reach to strengthen control efficiency and delay drug-fast effect.
Another object of the present invention provides a kind of insecticide that contains fluorine bell urea and malathion and is being used to prevent and treat the application on fleahopper silk worm or the cotton bollworm insect.
In order to realize the object of the invention, researcher of the present invention carries out bioassay results according to the reasonable composite equivalence principle of agricultural chemicals with different compound proportions, selects fluorine bell urea and malathion to carry out composite.
Insecticide of the present invention contains the active ingredient of following weight portion:
Fluorine bell urea: 2～10
Malathion: 5～40.
Preferably, insecticide of the present invention contains the active ingredient of following weight portion:
Fluorine bell urea: 4～8
Malathion: 10～40.
More preferably, insecticide of the present invention contains the active ingredient of following weight portion:
Fluorine bell urea: 5～7
Malathion: 25～35.
Can above-mentioned active ingredient and suitable auxiliary material be prepared into missible oil, suspending agent, aqueous emulsion or dispersible granule according to method well-known to those skilled in the art.
A kind of preferred scheme is to be prepared into missible oil, and said auxiliary material comprises emulsifier and solvent, and wherein emulsifier accounts for 5%～30% of missible oil gross weight, and solvent accounts for 40%70% of missible oil gross weight.
Described emulsifier is selected from: one or more among agricultural newborn 600#, Nongru-700 #, 2201, OP-21, OP-10, AEO (fatty alcohol and ethylene oxide condensate) or the JFC (polyoxyethylene ether compound).Be preferably: OP-21 or AEO.
Described solvent is selected from: any one in dimethyl formamide, methyl alcohol, phenmethylol, ethanol, ethylene glycol, dimethyl sulfoxide (DMSO), glycerine, isopropyl alcohol, n-butanol, N-Methyl pyrrolidone, cyclohexanone or the xylol or multiple.Be preferably in dimethyl formamide, ethanol, N-Methyl pyrrolidone, xylol or the cyclohexanone any one or multiple.
The described component that contains the missible oil of fluorine bell urea and malathion all can adopt technology well known in the art to be processed into the missible oil formulation by commercially available acquisition.
Specifically, above-mentioned missible oil can adopt following method preparation:
In the container that thermometer and agitator are housed, add fluorine bell urea, malathion and solvent, be heated to 30 ℃～50 ℃; Stirred 30～90 minutes; Evenly add temperature then and be 40 ℃ emulsifier and stir, stirred 60 minutes, when treating that temperature is reduced to 20 ℃; This moment, soup was a transparency material solution, filter the back high fluorine bell urea and malathion missible oil.
The described missible oil that contains fluorine bell urea and malathion can be used for preventing and treating insects such as fleahopper silk worm or cotton bollworm.
The missible oil that contains fluorine bell urea and malathion according to the invention is generally effective ingredient consumption 200～600g/ha. (per hectare effective ingredient consumption) at the application dose of field control fleahopper class pest and sprays.The missible oil application process that contains fluorine bell urea and malathion of the present invention is: according to recommending consumption, in sprayer, spray behind the dilute with water.
Insecticide of the present invention has the following advantages:
1. fluorine bell urea is different to the mechanism of action of insect with the malathion, and the mode of action has certain complementarity again, and add between the two composite and have very high synergistic effect, be a kind of desirable insecticide binary combination therefore.
2. the combination of fluorine bell urea of the present invention and malathion reaches mutual supplement with each other's advantages, improves drug effect, reduces cost, the effect of delaying drug resistance, minimizing chemical pesticide consumption.
3. the missible oil that contains fluorine bell urea and malathion of the present invention can be applicable to prevent and treat insects such as fleahopper silk worm, cotton bollworm.
