Abstract
The invention provides a pesticide composition and the application thereof, wherein the composition contains nitenpyram and pyridaben, and is used for controlling agricultural pests and acarus. The pesticide composition is prepared by the nitenpyram and the pyridaben, so that the composition shows excellent synergism within a certain preparation range, improves pest killing effect remarkably compared with a single preparation, simultaneously reduces use dosage of pesticide, application labor and cost, adverse effect to environment and pesticide residue, and has remarkable economic benefit and environmental benefit. In addition, action mechanisms of effective components of the nitenpyram and the pyridaben in the composition are different, so that the compositione combined by the nitenpyram and the pyridaben can delay or overcome drug resistance of pests, and prolong service life of the single preparation.
Description
Technical field
The present invention relates to a kind of agricultural chemical composition for disinsection and application thereof, be used to prevent and treat insect and mite on the agricultural.
Background technology
Rice fulgorid is the important pests on China's Rice Production.Rice fulgorid mainly contains three aspects to the harm of paddy rice: sting suction rice juice 1..Adult of rice fulgorid and nymph are clustered in rice clump bottom, lunge in the paddy rice cane tissue with piercing mouth parts and to suck juice, and glandula is secreted a kind of noxious material when getting food, destroy rice strain tissue, many brown spots appear on the killed cane, endanger when serious, standing grain clump base portion is pitchy, and complete stool is withered gradually.Worm is measured when big, is everlasting to make paddy rice blue or green withered and dead in a short time, and the in flakes dead bar in rice field lodges.When late growth stage of rice endangers in a large number,, often can not go out fringe or become empty grain fringe if be injured booting stage; If the heading back is killed, then influence the paddy plumpness, thousand kernel weight alleviates, and rate of immatured grain increases.2. lay eggs and stab.When the female worm of rice fulgorid lays eggs, thrust leaf sheath and the cane tissue causes a large amount of wounds, destroy conducting tissue, hinder the conveying of nutriment with sharp-pointed ovipositor.3. cause that disease takes place.Rice fulgorid is the communication media of some paddy rice virus disease, and the wound by getting food, laying eggs and cause, and helps infecting of some rice disease.
Select at rice grub control medicament, the organophosphorous pesticide of many high poison, high residue is prohibited use by country.For a long time, the control of rice fulgorid relies on the medicament that Imidacloprid, buprofezin etc. are efficient, the lasting period is long.Regrettably, according to Ministry of Agriculture's damage by disease and insect monitoring for resistance laboratory investigation and research for many years, the rice fulgorid of some areas has produced pesticide resistance in various degree to medicaments such as Imidacloprids, and control efficiency is very poor.
Homoptera pests such as Bemisia tabaci, trialeurodes vaporariorum, leafhopper, aphid, because growth cycle is short, reproduction speed is fast, and breeding quantity is many, and generation overlap is serious, and control is got up very difficult, is easy to generate pesticide resistance simultaneously.
Therefore, seek the prevention and treatment method that has prevention and delaying drug resistance generation and can effectively tackle resistant insect and seem particularly important.
Coming pest control with the novel pesticide that does not have cross resistance is a good solution.But develop a novel pesticide at present and need screen 1 ten thousand-1.2 ten thousand compound, expensive 1.2-1.5 hundred million dollars, the construction cycle is 5-10 years, is difficult to catch up with the speed that insect produces resistance.Other method such as crop allocation adjustment, different agricultural chemicals are rotated etc., in the process of practical operation, are difficult to really play obvious effects.
Nitenpyram is a kind of efficient, wide spectrum, novel nicotinamide insecticide, and it mainly acts on the insect nerve, the aixs cylinder of insect is touched acceptor have the nerve block effect.Nitenpyram has remarkable interior suction and osmosis, consumption is few, toxicity is low, lasting period is long, crop safety there are not advantages such as poisoning, be widely used on paddy rice, wheat, cotton, cucumber, eggplant, radish, tomato, potato, muskmelon, watermelon, peach, apple, pears, oranges and tangerines, grape, the tea, control Homoptera and Semiptera insect, for example rice fulgorid, aphid, thrips, trialeurodes vaporariorum, Bemisia tabaci, leafhopper, thrips etc., the insect that conventional pesticides has been produced resistance has good control efficiency.
Pyridaben has another name called fast mite spirit, pyridaben, the magnitude of leading a cow, be efficient, wide spectrum miticide, absorption in not having is to tetranychid, Panonychus citri, unguiculus mite, close planting property of food such as goitre mite and do harm to mite and all have obvious control efficiency, and to ovum, if mite, become mite all effective, also effective to the mobile phase that becomes mite.
The composite pest control that is applied to of Nitenpyram and pyridaben is still reported nothing humanity at present.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of control efficiency good, the potentiating pesticidal composition pesticide that drug cost is low.
Another purpose of the embodiment of the invention is to provide the application of above-mentioned agricultural chemical composition for disinsection.
The agricultural chemical composition for disinsection of the embodiment of the invention, active ingredient wherein is made up of Nitenpyram and pyridaben.
The application of above-mentioned agricultural chemical composition for disinsection in preparation pest control and mite agricultural chemicals.
Technique scheme, owing to adopt Nitenpyram and pyridaben is composite forms, in certain ratio range, show fabulous synergistic effect, the insecticidal effect of composition is significantly improved than single agent, using dosage, dispenser recruitment and the cost of agricultural chemicals have been reduced simultaneously, also reduced harmful effect and residue of pesticide, had remarkable economic efficiency and environmental benefit environment.In addition, active ingredient Nitenpyram and pyridaben mechanism of action in the present composition are different, are combined into composition and use the pesticide resistance that can delay or overcome insect, prolong the service life of single agent.

Biological activity test
1, indoor biological activity determination
Test medicine adopts Nitenpyram and pyridaben, with adding emulsifier after the dissolution with solvents, is diluted with water to suitable concentration.Each chemicals treatment is established 5-7 concentration gradient, and establishes blank clear water contrast.Rice stem infusion process is adopted in test.The time that the rice stem is immersed in the soup is 30 seconds.Treat that soup on the rice stem preserves moisture rice stem root after air-dry with the cotton ball parcel, be positioned in the disposal plastic cup.Four repetitions of every processing, each repeats to connect 30 tritonymphs.After connecing worm, place 16H/8H illumination constant incubator (27 degrees centigrade) to cultivate on the rice stem.4 days checkout facility results behind the medicine, the statistics lethality.
With each logarithm value of handling effective ingredient concentration (μ g/ml) is independent variable X, and the probit value that inhibiting rate changes into is dependent variable Y, uses the expert data DPS of statistical software to handle, concentration LC in calculating the virulence regression equation formula and suppressing
50
Calculate the toxicity index of each medicament and the co-toxicity coefficient of mixture (CTC value) according to the abundant method of Sun Yun, CTC≤80 are antagonism, and 80＜CTC＜120 are summation action, and CTC 〉=120 are synergistic effect.Experimental result sees Table 1 (proportioning is a mass ratio in the table 1).
The composite Toxicity Determination result of table 1 Nitenpyram and pyridaben to rice fulgorid
| Medicament and proportioning | Lethal concentration of 50 LC 50(ug/ml) | Co-toxicity coefficient (CTC) |
