Description
The present invention relates to the biocide of crop pests, especially a kind ofly overcome drug-fast agricultural chemicals-eliminating and resisting phosphorus.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 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 show as more very with cotton-plant pest-insects (be often referred to: cotten aphid and cotton bollworm, hereinafter to be referred as " cotton worm "); 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 agricultural chemicals or anti-medicine takes place to make a variation.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 that causes the group effect that adapts to a certain single agent agricultural chemicals.This have the almost consistent insecticidal mechanism of drug-fast gene pairs and must form similar multiple choices, resists or avoid the fatal group of above-mentioned agricultural chemicals.Thereby insect is also to producing the cross resistance relation between above-mentioned agricultural chemicals, thereby facilitates the pesticide resistance surge of insect to above-mentioned agricultural chemicals, do not apply and uses to cause most agricultural chemicals to fall to imitate.
In agricultural chemicals market, a kind of " mite-killing pesticide " agricultural chemicals has appearred, and it utilizes the mechanism of action separately (actual is the mutual synergistic effect of two kinds of agricultural chemicals) of two kinds of agricultural chemicals different with insecticidal spectrum, is equipped with " synergist " again and reaches and overcome drug-fast purpose.Used " synergist " of this mixture, itself no insecticidal action just can play synergistic effect to above-mentioned two agricultural chemicals.But after in a single day above-mentioned two agricultural chemicals were produced high resistance by insect, the synergistic effect of this synergist was also just not obvious.
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 agricultural chemicals intersect the reduction pesticide resistance each other to insect), increase the physics insecticidal mechanism again, make multiple insecticidal mechanism acting in conjunction, 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:
Except the malathion to decis, have outside the mutual synergistic effect, also have through experiment: there is mutual synergistic effect the malathion to nuvacron.Also have Methomyl that decis, Methomyl are had the negative cross resistance relation to nuvacron simultaneously.And malathion and Methomyl do not have the cross resistance relation.The present invention is exactly to be equipped with decis (or cyhalothrin or come the good fortune spirit) or to be equipped with nuvacron with Methomyl, malathion, diesel oil or the machine oil that a large amount of having makes insect breathing smothering action is gone in auxiliary tone again, call in a small amount of organic compound emulsifying agent, can constitute the novel drug-fast agricultural chemicals-eliminating and resisting phosphorus that goes out.
The material proportion of this eliminating and resisting phosphorus agricultural chemicals is as follows:
Material content %(weight per volume)
Malathion: 3～20
Chrysanthemum ester: 0.1～0.5
Methomyl: 1～10
Diesel oil or machine oil: 40～90
Organic compound emulsifying agent: 3～10
Perhaps following proportioning:
Material content %(weight per volume)
Malathion: 3～20
Nuvacron 3～20
Methomyl: 1～10
Diesel oil or machine oil: 40～90
Organic compound emulsifying agent: 3～10
In order to make in the above-mentioned prescription preceding four kinds of raw materials can mixing and emulsifying even, used emulsifier be organic compound emulsifying agent, and it is the emulsifier of the Different Weight ratio of polyoxyethylene carboxylate and alkylphenol polyoxyethylene.Its weight ratio is: 1: 1, and 3: 7,4: 6,6: 4,7: 3.Such emulsifier can make the preceding four kinds of raw materials in the above-mentioned prescription fully emulsified under stirring action, and static back and not stratified makes this agricultural chemicals-eliminating and resisting phosphorus can long term storage, but and thin up several times and be used for the farmland.
The production method of the eliminating and resisting phosphorus agricultural chemicals of above-mentioned prescription is: with each five kinds of material in the above-mentioned prescription, drop into successively in the modulation kettle by proportioning, fully stir, mixing and emulsifying is even, promptly gets the eliminating and resisting phosphorus agricultural chemicals.
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, have saved " the synergy phosphorus " of no insecticidal action own.The insect of the heavy dose that increases breathes asphyxiant-diesel oil or machine oil.This effect with physical features, it makes outside the insect death by suffocation except stopping up the breathing duct of insect, can also assist agricultural chemicals to infiltrate in the insect body.This is because the wax on this diesel oil or machine oil and pest body surface is the matter of dissolving each other.Heavy dose of mineral hydrocarbon oils portability emulsifications such as diesel oil 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, the drug resistant gene that makes its genetic variation has little time to duplicate or modification and destroyed.Overcome drug-fast purpose thereby reach.
Cooperatively interact between each composition in the agricultural chemicals of this invention, promote drug effect performance effect more fully separately.So also toxic low, high and low characteristics residual, pollution-free, safe in utilization of drug effect of this agricultural chemicals, especially this agricultural chemicals has utilized the effect of " negative cross resistance relation " and " insect breathes asphyxiant ", make this agricultural chemicals outstanding control efficiency be arranged, can prevent that also insect from producing new pesticide resistance the insect that has resistance.This agricultural chemicals is easy to use, and spraying times and dosage all are significantly smaller than the single-dose consumption, thereby has reduced the use cost of agricultural chemicals.This agricultural chemicals can be widely used in the cotton worm of control, grain worm, the hundreds of insects on the crops such as fruit tree, forestry if use with spray-on process.
