Abstract
The invention discloses a compound pesticide of quinalphos and hexaflumuron, pertaining to the technical field of compound pesticides. The compound pesticide of the quinalphos and the hexaflumuron comprises hexaflumuron of 0.1 to 10wt percent and quinalphos of 10 to 50wt percent; the best proportion of hexaflumuron to quinalphos is 1: 20 to 40. The co-toxicity coefficient of the compound pesticide of the invention is 126.98 to 340.43, has good effect in control of harmful resistant insects such as chilo suppressaliq, tryporyza incertulas, cnaphalocrocis medinalis, cotton bollworm, smaller green leaf hopper and diamond back moth, etc. with a control rate of 98.56 percent, and good quick lasting effect, little harm to environment and human beings and low use-cost.
Description
Technical field
The present invention relates to technical field of pesticide, specifically, the present invention relates to the Recompounded pesticide of a kind of quinalphos and fluorine bell urea, be applicable to resistant insects such as control striped rice borer, paddy stem borer, rice leaf roller, cotton bollworm, smaller green leaf hopper, diamond-back moth.
Background technology
Because the long-term chemical insecticide that uses single formulation of people, insect is easy to generate pesticide resistance, in order to reach pest controling effect, have to use more highly toxic agricultural chemicals or strengthen the agricultural chemicals usage amount, so not only increase the weight of peasant's financial burden, pollution of ecological environment, destroy the ecological balance, influence the safety of agricultural product, and pest natural enemy is killed in a large number, causes insect more rampant.Have a large amount of mixed insecticides in the market, most for being mixed between the chemical pesticide, big to people and animals' toxicity, and also through after using for a long time, insect also can develop immunity to drugs.
Fluorine bell urea is a kind of insecticidal activity height, the wide specificity insecticide of insecticidal spectrum, can be used for various crop such as vegetables, cotton, fruit tree, forest and prevent and treat multiple lepidoptera pest, and the insect of organic phosphor, carbamates, pyrethroid generation resistance is had good result.Quinalphos belongs to medium malicious organophosphorus insecticide, and insecticidal spectrum is wide, quick-acting good, the lasting period is poor, and price is lower, and the snout moth's larva of rice has produced tangible resistance to this medicine at present, and control efficiency descends.
Summary of the invention
The present invention has overcome above-mentioned shortcoming, proposed the Recompounded pesticide of a kind of quinalphos and fluorine bell urea, compatibility is reasonable, and is simple to operate, good disinsection effect can effectively be controlled the generation and the harm of multiple resistant insects such as striped rice borer, paddy stem borer, rice leaf roller, cotton bollworm, smaller green leaf hopper, diamond-back moth.
The present invention solves the technical scheme that its technical problem takes:
The main component of this formulation is that fluorine bell urea content is 0.1～10wt%, and quinalphos content is 10～50wt%, and the best proportioning of fluorine bell urea and quinalphos is 1: 20～40.
The Recompounded pesticide of quinalphos of the present invention and fluorine bell urea is made up of following raw materials by weight percent: fluorine bell urea content is 0.1～10wt%, quinalphos content is 10～50wt%, emulsifier content is 1～15wt%, cosolvent content is 1～20wt%, antifreezing agent content is 1～7wt%, and stabiliser content is 0.2～10wt%, and synergist content is 0.1～5wt%, solvent is 20～60wt%, and pH value conditioning agent content is 0.01～3wt%.
By carrying out reasonably compositely with quinalphos, through series of selection test, the tangible composition of selective advance, strengthen quick-acting, reducing pesticide cost is key point of the present invention.
In the Recompounded pesticide of quinalphos and fluorine bell urea, described emulsifier is to be selected from farming breast 2201, farming breast 650, farming breast 0201, the farming breast 0204 one or more; Cosolvent is to be selected from ethanol, absolute ethyl alcohol, methyl alcohol, isoamyl alcohol, dimethyl formamide, the acetone one or more; Antifreezing agent is to be selected from ethylene glycol, propane diols, glycerine, the urea one or more; Stabilizing agent is to be selected from xanthan gum, CMC, Sodium Polyacrylate, the aluminium-magnesium silicate one or more; Synergist is to be selected from Butacide, Piprotal, the sulfoxide one or more; Solvent is selected from ethanol, methyl alcohol, isoamyl alcohol, dimethylbenzene, toluene, C
9Aromatic hydrocarbons, C
10In aromatic hydrocarbons, the ketone one or more; PH value conditioning agent is to be selected from acetic acid, hydrochloric acid, sodium hydroxide, the potassium hydroxide one or more.
In the preparation process of quinalphos and hexaflumuron compounded missible oil, former medicine (former powder) is dissolved with cosolvent, partial solvent has high input in modulation kettle, then under agitation, drop into former medicine, emulsifier, stabilizing agent, synergist, pH value conditioning agent and residual solvent successively, stir, analyze, filter, packing, promptly.
The Recompounded pesticide of above-mentioned quinalphos and fluorine bell urea also can be processed into other formulations such as soluble liquid, microemulsion, processing method processing routinely.
The invention has the advantages that:
1. in the Recompounded pesticide process of preparation quinalphos and fluorine bell urea,, guaranteed the stability and the stability of formulation of active insecticidal components, be convenient to store and transportation that the shelf time is long by adding various auxiliary agents.
2. quinalphos and fluorine bell urea are mixed according to the above ratio, have both kept the advantage of single agent itself, and the reduction of mixture dosage, and drug effect increases substantially, and has remedied the deficiency of single agent.
3. above-mentioned mixture has distinguished effect to multiple resistant insects such as striped rice borer, paddy stem borer, rice leaf roller, cotton bollworm, smaller green leaf hopper, diamond-back moths, has enlarged the control of insect spectrum, has delayed pesticide resistance.
4. utilizing two kinds of agricultural chemicals that the different mode of action of insect, the mechanism of action reasonably are mixed, is to prolong agricultural chemicals service life, delay pest resistance to insecticide, reduce the effective way of agricultural chemicals toxic and side effect.
5. above-mentioned mixture reasonable mixture ratio has strengthened quick-acting, has reduced the agricultural chemicals use cost, to the infringement of ecotope with pollute for a short time, helps protecting the person poultry safety, the mixture preparation that be that a class is efficient, low toxicity, insect is difficult to develop immunity to drugs.
