Description

A kind of composition containing pyrethroid insecticides and application thereof

Technical field

The invention belongs to pesticide field, relate to a kind of synergistic complex composition containing two kinds of active components, be specifically related to a kind of composition containing pyrethroid insecticides and application thereof.

Background technology

In the real process of agricultural production, using chemical agent is one of the most effective means of control plant pest, but is insect, the drug-fast generation of evil mite by the problem that chemical control insect the most easily produces.Use single pest control with insecticide, miticide continuously high dose simultaneously for a long time, easily cause the series of problems such as the remaining of medicament, environmental pollution.Composite or the mixture of rational pest control with insecticide, miticide has and expands desinsection, kills mite spectrum, improve control efficiency, extend the optimum period for applying fertilizer, reduce dosage, reduce poisoning, reduce and remain, delay insect, evil mite drug resistance and the positive feature such as drug-fast generation and development, the composite or mixture of Insecticidal and acaricidal agent is one of the effective method the most solved the problem.

Pyrethroid insecticides take natural products as the pesticide species that lead compound is succeeded in developing.That to have bioactive natural products pyrethrin be lead compound, the insecticides for health and crop protection carrying out that further synthesis optimizing obtains, existing tens kinds of this insecticides at present.Pyrethrin from chrysanthemum Tanacetum cinerariifolium or its extract, at present still for preventing and treating public health insect.Pyrethrin has six components (pyrethrin I, pyrethrin II, cinerin I, cinerin II, jasmolin I, jasmolin II), and wherein pyrethrin I has contact toxicity, and pyrethrin II knocks down activity.Pyrethroid insecticides is efficient, the broad spectrum pesticide that a class can prevent and treat various pests, and it has strong action of contace poison to insect, and quick-acting is good, and power of knocking down is fast.Pyrethroid insecticides is to the virulence of insect than other common insecticide height 1-2 order of magnitude, and its mechanism of action upsets the normal physiological of insect nerve, make it by excited, spasm is dead to benumbing.The insect of pyrethroid insecticides to aspects such as agricultural, gardening, warehouse, herding, health all has good control efficiency, but to mite class weak effect.

Chinese invention patent CN101906075A discloses the purposes of a kind of E-type phenyl acrylates compounds containing substituted anilino pyrimidine group and Control pests thereof, evil mite, wherein compound 9(Universal Chinese character name: phonetic mite amine, English common name: pyriminostrobin) can be used for preventing and treating various pests, evil mite, especially to mite class, there is outstanding control efficiency, be subject to the extensive attention of industry.This structural formula of compound is as follows:

Different cultivars composition carries out composite, may produce the technique effect that some is unexpected, is also one of control resistant insect, the effective ways doing harm to mite.But, have no the report of phonetic mite amine and pyrethroid insecticides complex composition so far.

Toxicity measures embodiment

Embodiment 19: phonetic mite amine and gamma cyhalothrin mixture are tested the indoor joint toxicity measuring of Tetranychus cinnabarinus

For examination target: Tetranychus cinnabarinus [Tetranychus cinnabarinus(boisduval)] become mite, the sensitive strain of indoor feeding.

Drug solution preparing: according to different tests needs, accurately take test sample respectively with electronic analytical balance, former medicine with acetone solution, then becomes the serial liquid of tool finite concentration gradient according to experimental scheme dose dilution with 0.1% Tween 80 water.

Test method: adopt potted plant seedling spray-on process to measure active size Tetranychus cinnabarinus being become to mite.First becoming mite to receive Tetranychus cinnabarinus of the same size is on the Tolerance of Kidney Bean Seedlings blade of first pair of true leaf open and flat phase, after becoming mite stable, count radix; Then by the order even spraying of experimental scheme from low dosage to high dose, every strain 1.5mL, often processes and repeats for 3 times, separately establish blank.

Be placed in observation ward by the examination material after process, the temperature of observation ward, humidity, illumination are adjustable as required.72 hours " Invest, Then Investigate " mite numbers dead, alive.With abbott formulae discovery corrected mortality, carry out statistical analysis with DPS data processing software, obtain each the virulence regression equation formula, the LC that use with for examination single dose and variant proportioning ₅₀value and 95% confidence limit, then use Sun Yunpei (Suny-p) method to calculate the co-toxicity coefficient of each proportioning, evaluate mixed effect, result of the test is in table 1.

The co-toxicity coefficient (CTC value) of mixture is by following formulae discovery:

ATI = \frac{S}{M} \times 100

In formula: ATI-mixture actual measurement toxicity index; The LC of S-standard agent ₅₀; The LC of M-mixture ₅₀.

TTI=TIA×PA+TIB×PB

In formula: the theoretical toxicity index of TTI-mixture; TIA-A medicament toxicity index; The percentage composition of PA-A medicament in mixture; TIB-B medicament toxicity index; The percentage composition of PB-B medicament in mixture.

CTC = \frac{ATI}{TTI} \times 100

In formula: CTC-co-toxicity coefficient; ATI-mixture actual measurement toxicity index; The theoretical toxicity index of TTI-mixture.

The co-toxicity coefficient (CTC) of built agent: CTC >=100 show as synergistic effect; CTC≤100 show as antagonism.

Phonetic mite amine and gamma cyhalothrin mixture the results are shown in Table 1 to the indoor joint toxicity measuring of Tetranychus cinnabarinus.

Embodiment 20: phonetic mite amine and gamma cyhalothrin, cypermethrin, beta-cypermethrin mixture are tested brown plant-hopper synergism determination

For examination target: brown plant-hopper [Nilaparvata lugens(Stal)] nymph, the sensitive strain of indoor feeding.

Test method: adopt the active size of potted plant seedling spray-on process mensuration to rice brown planthopper nymph.First plant in culturing pot by rice seedling, by the order even spraying of experimental scheme from low dosage to high dose, every strain 2mL, is then connected on rice seedling by rice brown planthopper nymph of the same size, often processes 3 times and repeats, separately establish blank.

Be placed in observation ward by the examination material after process, the temperature of observation ward, humidity, illumination are adjustable as required.72 hours dead, alive borer populations of " Invest, Then Investigate ".By the actual measurement lethality of each process of abbott formulae discovery.

Mixture effect assessment adopts Bliss method, and the independent joint action concept that Bliss proposes according to it is thought, theoretical lethality P during Mixture Use of Insecticides can calculate with following formula:

P=Pm+Pn（1-Pm）

Pm is the actual measurement lethality (%) of the first active component target when concentration is m; The actual measurement lethality (%) of Pn is the second active component working concentration when being n target.

If two kinds of active components are being greater than theoretical lethality P with the actual of the rear target of finite concentration mixing, are then judging that two kinds of active components are used in combination under setting concentration and there is synergistic effect, otherwise be then antagonism.
