Description

A kind of composition pesticide and application thereof containing tefluthrin and fluorine pyridine worm amine nitrile
Technical field
The present invention relates to a kind of composition pesticide, is with tefluthrin and fluorine pyridine worm amine nitrile for active ingredient, for preventing and treating peanut cutworm.
Background technology
Agrotis Lepidoptera Noctuidae, what agricultural crops worked the mischief has more than 10 to plant, and wherein black cutworm, white line dart moth of turnip, large cutworm, white edge cutworm and alert line cutworm etc. are particularly important.Polyphagy insect, mainly with larva harm seedling, subaerial for seedling stem bites broken by larva, makes whole strain dead, causes the disconnected ridge that is short of seedling, have a strong impact on crop yield.
Tefluthrin belongs to pyrethroid insecticides, it is soil insecticide, the Lepidoptera that can prevent and treat coleoptera well and perch in soil and some Diptera pest, can prevent and treat the soil pests such as pumpkin 12 star first, wireworm, flea beetle, chafer, Atomaria linearis, cutworm, corn borer, Oscinella frit.Application method is flexible, and available conventional equipment spreads granula, table soil and ditch spread or seed treatment.
Fluorine pyridine worm amine nitrile is an insecticide of sulfimide, and sulfimide acts on the nervous system of insect, namely acts on binding site unique in choline receptor and plays insecticidal function.Can through leaf, stem, root absorption and entering in plant corpus.
The present inventor conducts in-depth research tefluthrin and the combination of fluorine pyridine worm amine nitrile, find that Diacloden and the combination of fluorine pyridine worm amine nitrile have synergistic effect to cutworm, granule is prepared into by existing technology, in actual use, good control efficiency is had to elimination of underground destructive pests cutworm, after further study, the present invention is completed.
Summary of the invention
Technical problem to be solved: the present invention is directed to prior art deficiency and provide a kind of containing tefluthrin and fluorine pyridine worm amine nitrile composition pesticide, said composition has synergistic effect, improves peanut cutworm control efficiency.
Technical scheme: a kind of composition pesticide containing tefluthrin and fluorine pyridine worm amine nitrile, active ingredient is tefluthrin and fluorine pyridine worm amine nitrile, tefluthrin and the ratio of quality and the number of copies of fluorine pyridine worm amine nitrile in composition pesticide are 50:1 ~ 1:50, and tefluthrin and the percentage by weight of fluorine pyridine worm amine nitrile quality summation in composition pesticide are 0.1 ~ 40%.
The formulation of composition pesticide of the present invention by selecting suitable insecticides adjuvant to be processed into granule.
Described insecticides adjuvant is: 0.5% ~ 3% dispersing aid, 0.1% ~ 2% sustained release agent, 0.1% ~ 5% binding agent, 0.5% ~ 20% carrier, and all the other are filler.Wherein, sustained release agent is the one of polyvinyl alcohol or gum Arabic, binding agent is the one of polyethylene glycol or industrial gelatine, and dispersing aid is the one of corn starch or sweet potato starch, and described filler is the mixing of one or more of calcium bicarbonate, kaolin and quartz sand.
Composition pesticide of the present invention is mainly used in the control of control elimination of underground destructive pests, especially peanut cutworm.
The present invention is tefluthrin and fluorine pyridine worm amine cyanide composition, can improve agricultural insect pests control effect, also plays positive impetus to the minimizing countryside tax system of user and the increasing both production and income of agricultural.
Specifically, granule of the present invention has following advantage:
1, tefluthrin and fluorine pyridine worm amine nitrile combine and have synergistic function, significantly improve the control efficiency to insect, expand insecticidal spectrum simultaneously, solve the defect to some insect weak effect when single dose is used alone than the single use of single dose.
2, tefluthrin and fluorine pyridine worm amine nitrile combine, and decrease Pesticide use amount, reduce use cost, alleviate pollution to environment.
3, tefluthrin is different from the fluorine pyridine worm amine nitrile mechanism of action, and the two mixture can delay the generation of pest resistance to insecticide, adds the service life of agricultural chemicals.
Embodiment
In order to make object of the present invention, technical scheme and advantage more short and sweet, the following specific embodiment of the present invention is described, but the present invention is only limitted to absolutely not these examples.The following stated is only the good embodiment of the present invention, only for describing the present invention, can not be interpreted as the restriction to scope of the present invention.It should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
Embodiment one: Toxicity Determination is tested
For examination worm: indoor for many generations raise Individual Size consistent with physiological status three age cutworm larva.
Reagent agent: the former medicine of tefluthrin and the former medicine of fluorine pyridine worm amine nitrile.
Test method: adopt drop method to measure, with reference to " People's Republic of China (PRC) agricultural industry criteria NY/T1154.1-2006 ", concrete grammar is as follows.
First by micro intravenous drip device solvent clean, regulate dropper to stand-by state.Then the examination worm CO of neat and consistent is chosen with writing brush 2mild paralysis is placed in 9cm culture dish, finally with micro intravenous drip device, medicament is dripped to the belly of polypide by head, every some drops physic liquor 0.5 μ L, the process of the corresponding acetone contained with drop 0.5 μ L is contrast, the examination worm after drop is placed in temperature 28 ± 1 DEG C, relative moisture is in the intelligent insectary of 70%.Often process and repeat for 4 times, often repeat 20 examination worms.After process, 24h investigation examination worm death condition, records total borer population and dead borer population.
Carry out statistical analysis with DPS statistical analysis software, calculate the LC of each medicament 50, and co-toxicity coefficient (the CTC value of mixture is calculated according to the abundant method of Sun Yun.)
Actual measurement toxicity index (ATI)=(standard agent LC 50/ reagent agent LC 50) × 100
In theoretical toxicity index (TTI)=A medicament toxicity index × mixture A percentage composition+B medicament toxicity index × mixture in the percentage composition of B
Co-toxicity coefficient (CTC)=[the theoretical toxicity index (TTI) of mixture actual measurement toxicity index (ATI)/mixture] × 100
According to the NY/T11547.7-2006 insecticide combination effect criteria for classifying: co-toxicity coefficient (CTC) >=120 shows as synergistic effect; Co-toxicity coefficient (CTC)≤80 shows as antagonism; 80 < co-toxicity coefficient (CTC) < 120 show as summation action.
Measurement result shows, to cutworm CTC value >=120 in the scope of tefluthrin and fluorine pyridine worm amine nitrile portfolio ratio 50:1 ~ 1:50, illustrate that tefluthrin and fluorine pyridine worm amine nitrile combine and belong to synergistic effect to the synergy of cutworm, tefluthrin and fluorine pyridine worm amine nitrile combine has reasonability and feasibility.
