Abstract
The invention discloses an insecticide composition containing chlorine chlorfenapyr and pyridalyl. The insecticide composition comprises chlorine chlorfenapyr, pyridalyl and pesticide additives, wherein the weight ratio of chlorine chlorfenapyr to pyridalyl is (1:5) to (5:1); the weight sum of chlorine chlorfenapyr and pyridalyl accounts for 3-97% of the composition in percentage by weight. According to practical application demands, the insecticide composition can be prepared into one of emulsion, microemulsion, a suspending agent, wettable powder and a water dispersible granule, and is used for preventing and treating agricultural insects.
Description
Technical field
The present invention relates to a kind of chlorine chlorfenapyr and pyridalyl Pesticidal combination, is with chlorine chlorfenapyr and pyridalyl for active ingredient, for preventing and treating pest, and the lepidoptera pests such as such as diamond-back moth, prodenia litura, beet armyworm, leaf roller, armyworm.
Background technology
The resistance problem of pest is global problems, is the emphasis problem that agricultural science and technology worker pays close attention to always.Along with the continuity year in year out of Chemical Control of Harmful Insects, the increase of Pesticide use amount and not scientifical use agricultural chemicals, pest resistance is day by day serious, and the pest species producing resistance is on the increase.Meanwhile, the use agricultural chemicals of high strength, causes Practice for Pesticide Residue in Agricultural Products to exceed standard, environmental pollution and the increase of peasant's drug cost etc., is unfavorable for agricultural sustainable development.Therefore, the insect growth regulator, IGR agricultural chemicals of efficient, the low toxicity of research and development, environmental protection has positive effect to agricultural sustainable development.
Chlorine chlorfenapyr is the noval chemical compound of Hunan Chemical Research Institute's synthesis, and its mechanism of action is by disturbing Intramitochondrial electrochemical gradient thus blocking oxide Phosphorylation events.Have pest such as lepidopterous larvae, coleoptera and Homopteras tag, stomach toxicity and comprehensive toxic action, applied widely, higher than chlorfenapyr to crop safeties such as melon, brassicaceous vegetables.
Pyridalyl is a kind of novel insecticidal agent, and its mechanism of action, with the conventional insecticide used is not similar at present, has multiple lepidoptera pest and highly selects insecticidal activity, separately have bibliographical information pyridalyl thrips also to be had to the effect suppressing population to spread.
The mixture of different pesticide species is the common methods of preventing and treating agriculture disease pest and weed.Being screened by formulation of pesticide, filter out rational formula, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay the drug-fast generation of disease pest and weed, is the important means that agricultural synthesis is administered.The recipe determination of the present inventor to chlorine chlorfenapyr and pyridalyl conducts in-depth research, and finds that chlorine chlorfenapyr and pyridalyl carry out mixture and have obvious synergistic effect in certain mixed ratio scope to insect, after further study, completes the present invention.
Composition and the application of chlorine chlorfenapyr and pyridalyl there is no report at present.

Above-mentioned raw materials is pulverized rear mixing in proportion, after abundant stirring and dissolving, complements to 100% by deionized water, continue to be stirred to transparent, be i.e. obtained 16% chlorine chlorfenapyr pyridalyl microemulsion.
Assays Example 1: chlorine chlorfenapyr and pyridalyl are tested the joint toxicity measuring of diamond-back moth
Test medicine adopts 98% chlorine chlorfenapyr raw material pesticide, the former medicine of 91% pyridalyl.
The diamondback moth larvae that field gathers is put into off-the-shelf Chinese cabbage seedling, after larvae pupation, pupa is collected in the culture dish being lined with moisturizing filter paper, put into cage of laying eggs to sprout wings by it, then the Chinese cabbage seedling of whole dish being put into cage of laying eggs allows diamondback moth larvae lay eggs, often coil Chinese cabbage seedling and fall ovum amount when reaching about 500, take out Chinese cabbage seedling dish, be placed on climatic cabinate [temperature: 24 ~ 26 DEG C; Relative moisture 70% ~ 80%; Illumination: 14 (L): 10 (D)] in allow egg hatching, raise to 3 instar larvaes.
The malicious blade method of folder is adopted to measure: to beat with the card punch of diameter 1cm and get leaf butterfly, put into culture dish, moisturizing.With capillary dropper from low concentration, every leaf butterfly drop 1ul liquid, involutory the making of leaf butterfly scribbling gelatinized corn starch after solvent volatilization with another sheet presss from both sides malicious leaf butterfly, makes in the complete hole being put in 12 hole tissue culturing plates.Often process and repeat for 4 times, often repeat to be no less than 12 malicious leaf butterflies of folder, and establish not containing the corresponding organic solvent of medicament process in contrast.Connect 1 examination worm in each hole of tissue culturing plate, be placed in normal condition and cultivate.After meeting worm 2 ~ 4h, after examination worm has taken food pastille leaf butterfly, in cultivation plate hole, add clean feeds continue to raise to investigation, eliminated the examination worm not eaten a complete leaf butterfly.Each dosage process examination borer population 80.After process, 48h investigation examination worm death condition, records total borer population and dead borer population.
According to survey data, calculate the corrected mortality of each process.And co-toxicity coefficient (the CTC value of mixture is calculated according to the abundant method of Sun Yun.If) contrast lethality < 5%, do not correct; Contrast lethality, between 5% ~ 20%, corrects; Contrast lethality > 20%, test need be reformed.Be independent variable x according to the logarithm value of drug concentration (mg/L), with the probit value of corrected mortality for dependent variable y, set up virulence regression equation formula respectively, adopt DPS software to calculate the LC of single dose and each proportioning mixture
50and mixture co-toxicity coefficient.
Actual measurement toxicity index (ATI)=(standard agent LC

| Chlorine chlorfenapyr: pyridalyl (1:5) | 1.233 | 191.48 | 128.90 | 148.55 |
As can be seen from Table 1, it is 125.32,142.56,150.49,147.65,148.55 that chlorine chlorfenapyr and pyridalyl combine diamond-back moth CTC value with 5:1,3:1,1:1,1:3,1:5 respectively, illustrate that chlorine chlorfenapyr and pyridalyl combination have synergistic effect to diamondback moth larvae, mixture can improve drug effect.
Assays Example 2: chlorine chlorfenapyr and the pyridalyl Pesticidal combination control lepidoptera pest test of pesticide effectiveness
Test site is positioned at mouth of a river town, Huizhou, in diamond-back moth, beet armyworm harm Sheng phase dispenser, adopts spray-on process.Adopt 10% chlorine chlorfenapyr suspending agent, 10.5% pyridalyl missible oil medicament in contrast, 7 chemicals treatment are established in test altogether, and each process repeats for 3 times.Cornerwise five somes investigation in district insect population radix is managed throughout, often some investigation 5 Brassica rapa L before dispenser.Within after dispenser 3 days, 7 days, respectively investigate a control efficiency, record residual borer population, calculate control efficiency by Revision insect recluced rate, result of the test is as shown in table 2.
Table 2, chlorine chlorfenapyr and pyridalyl composition for preventing and controlling wild cabbage diamond-back moth, beet armyworm result of the test
As can be seen from Table 2,30% chlorine chlorfenapyr pyridalyl wetting powder, 20% chlorine chlorfenapyr pyridalyl water dispersible granules, 15% chlorine chlorfenapyr pyridalyl suspending agent, 20% chlorine chlorfenapyr pyridalyl aqueous emulsion, 16% chlorine chlorfenapyr pyridalyl microemulsion control efficiency are better than 10% chlorine chlorfenapyr suspending agent and 10.5% pyridalyl missible oil.Do not find poisoning situation in experimentation, illustrate that chlorine chlorfenapyr and pyridalyl composition improve control efficiency, reduce the using dosage of agricultural chemicals, decrease the impact of agricultural chemicals on environment, reduce drug cost.
