Description
The present invention relates to the biocide of crop pests, especially a kind ofly overcome drug-fast agricultural chemicals-high oilness drug-resistance-extincted dimethylcyclopropanecarboxylate.It belongs to the insecticidal/acaricidal agent of technical field of pesticide.
Current, the pesticide variety of crops is various, and organophosphorus insecticide is arranged, chrysanthemum ester class, series pesticide agent such as carbamates.These agricultural chemicals have played important function over a period to come to kill pests protection crops; yet long-term use along with these agricultural chemicals; the primary pest of some crops; as: cotton aphid; cotton bollworm; European red mite; rice fulgorids etc. have all produced serious pesticide resistance to above-mentioned agricultural chemicals; especially (be often referred to: cotten aphid and cotton bollworm with cotton-plant pest-insects; hereinafter to be referred as " cotton worm ") show as more very; its pesticide resistance degree does not almost have the agent of a kind of agricultural chemicals list can prevent and treat drug-fast cotton worm preferably up to thousands of times.The insecticidal mechanism of above-mentioned agricultural chemicals nearly all is that the nervous system to insect suppresses, and then kill pests.The pesticide resistance of insect may be because the resistant gene of insect is selected by a certain agricultural chemicals or variation of drug resistance taken place.This is because all biological forms or physiological status all are the results of long-term variation and heredity.Therefore, use a certain single agent agricultural chemicals for a long time, must make the gene of insect produce variation and have the pesticide resistance of the effective fatal gene action that adapts to a certain single agent agricultural chemicals.This have drug-fast mutant gene and must form similar multiple choices to almost consistent insecticidal mechanism, resists or avoid the effective fatal gene of above-mentioned a certain agricultural chemicals with this.Thereby insect can also be to producing cross resistance relation (that is: the intersection of the pesticide resistance between two or more agricultural chemicals improves its drug-fast relation mutually) between above-mentioned several agricultural chemicals, thereby facilitate the pesticide resistance surge of insect, imitate and deposited the use to cause most agricultural chemicals to fall to above-mentioned agricultural chemicals.
On nearest agricultural chemicals market, a kind of " mite-killing pesticide " agricultural chemicals has appearred, its mechanism of action separately (actual is the mutual synergistic effect of two kinds of agricultural chemicals) that utilizes two kinds of agricultural chemicals is different with desinsection worm spectrum, is equipped with " synergist " again and reaches and overcome drug-fast purpose.Itself no insecticidal action of used " synergist " of this mixture just can play synergistic effect to aforementioned two agricultural chemicals.But after in a single day aforementioned two kinds of agricultural chemicals are produced high anti-medicine by insect (having produced pesticide resistance now), the synergistic effect of being somebody's turn to do " synergist " is also just not obvious.Therefore the pesticide resistance of " mite-killing pesticide " agricultural chemicals is anxious to be solved.
Task of the present invention is exactly the cross resistance relation that will overcome between agricultural chemicals, find the medicament of more synergy mutually and negative cross resistance relation (promptly two kinds of agricultural chemicals intersect the reduction pesticide resistance each other to insect), increase the physics insecticidal mechanism again, make the insecticidal mechanism of Multiple Pesticides cooperate jointly, reach and both can prevent and treat existing high drug-resistance insect, can prevent that again insect from producing new drug-fast purpose.
The objective of the invention is following realization:
The experiment proved that: except the malathion has the mutual synergistic effect chrysanthemum esters such as decises, the agricultural chemicals Methomyl also has the negative cross resistance relation to chrysanthemum esters such as decises.And do not have cross resistance to concern between malathion and the Methomyl.Common cooperation relation with three kinds of agricultural chemicals is equipped with other insecticidal mechanism again, just can solve the pesticide resistance problem.The present invention is exactly to be mixed effectively with pyrethrin pesticide and malathion and Methomyl, auxiliary tone is gone into a large amount of having and is made insect breathe the diesel oil of smothering action or machine oil as active solvent again, call in effective organic compound emulsifying agent of effective dose again, can constitute the novel drug-fast agricultural chemicals-high oilness drug-resistance-extincted dimethylcyclopropanecarboxylate that overcomes.
The material proportion of this high oilness drug-resistance-extincted dimethylcyclopropanecarboxylate agricultural chemicals is as follows:
Material content %(weight per volume)
Chrysanthemum ester 0.1～0.5
Malathion 3～30
Methomyl 1～20
Diesel oil or machine oil 40～90
Organic compound emulsifying agent 3～10
Above-mentioned five kinds of materials by certain proportioning, are dropped in the modulation kettle successively, fully stir, mixing and emulsifying is even, promptly gets the tan high oilness drug-resistance-extincted dimethylcyclopropanecarboxylate agricultural chemicals of clarifying.
In order to make in the above-mentioned prescription preceding four kinds of materials can mixing and emulsifying even, used emulsifier be effective organic compound emulsifying agent.This agent can be the compound emulsifying agent of the Different Weight ratio of ester emulsifying agent (as: polyoxyethylene carboxylate etc.) and ethers emulsifier (as: alkylphenol polyoxyethylene etc.).Its weight ratio is: 1: 1, and 3: 7,4: 6,6: 4,7: 3.Effective emulsifier like this can make preceding four kinds of raw materials in the above-mentioned prescription under abundant stirring action, fully emulsified, with static permanent and not stratified after reaching emulsification and finishing, but make both long term storage of this agricultural chemicals-high oilness drug-resistance-extincted dimethylcyclopropanecarboxylate, again thin up several times and be used for the farmland in use.
The described pyrethrin pesticide of this agricultural chemicals can be a decis, or cypermethrin, or cyhalothrin, or comes the good fortune spirit, or Uranus, or goes out and sweep profit.
This agricultural chemicals makes it overcome the agricultural chemicals pesticide resistance and increases owing to the synergistic effect and the negative cross resistance relation that have made full use of between some agricultural chemicals.Various compositions nearly all have insecticidal action in this agricultural chemicals, and have saved " the synergy phosphorus " of no insecticidal action own.The effective insect of the heavy dose that increases breathes asphyxiant-diesel oil or machine oil, this insecticidal action with physicochemical characteristic, it makes outside its death by suffocation except stopping up the breathing duct of insect, can also assist molten above-mentioned agricultural chemicals infiltrate in the insect body.This is because the wax on this effective diesel oil or machine oil and pest body surface is the matter of dissolving each other.Effectively heavy dose of mineral hydrocarbon oils portability emulsifications such as diesel oil above-mentioned three kinds of main insecticides, go deep into the insect body everywhere, not only to nervous system, and insect blood circulation system, respiratory system, digestive system etc. are all had suppress or destruction, make the position expanded range of insect exposed to pesticides, that is: make the drug resistance gene of its genetic variation, when having little time to duplicate or modify, just destroyed, destroyed the drug resistance gene of insect like this, overcome the drug-fast purpose of insect agricultural chemicals thereby reached.
The cooperation that cooperatively interacts between each composition in the agricultural chemicals of this invention promotes drug effect performance effect more fully separately.Therefore this agricultural chemicals is also toxic low, drug effect height, low-residual, pollution-free, safe in utilization characteristics.Especially this agricultural chemicals has utilized the effect of " negative cross resistance relation " and " insect breathes asphyxiant ", makes this agricultural chemicals to having drug-fast insect outstanding control efficiency be arranged.This agricultural chemicals can prevent that also insect from producing new pesticide resistance.Simultaneously, this agricultural chemicals is easy to use, and spraying times and dosage all are significantly smaller than single agent pesticide dosage, thereby has reduced the use cost of agricultural chemicals.This agricultural chemicals can be widely used in the cotton worm of control, grain worm, fruit tree pest insect, hundreds of insects such as forestry pest if use with spray-on process.
