Abstract
The invention discloses a nitenpyram and pyridaben containing pesticide composite, in which the pbm (parts-by-mass) ratio of nitenpyram to pyridaben is (1:20)-(20:1). A compound of the two effective components has an obvious synergistic effect, so that the control efficiency is improved, the control spectrum is expanded, and the dosages of the pesticides are reduced, thereby reducing the cost and the pollution to the environment. The pesticide composite disclosed by the invention is suitable to be used for preventing and controlling various pests such as aphids, plant hoppers, thrips, whiteflies and red spiders of crops such as vegetables, paddy rice and fruit trees.
Description
Technical field
The present invention relates to composition pesticide, is to be active ingredient with Nitenpyram and pyridaben, belongs to the agriculture chemical compounding field.
Background technology
Crops are because damage by disease and insect causes crop yield loss to estimate, and chemical control then is the main path that the control damage by disease and insect takes place, and need use a large amount of agricultural chemicals for this reason every year and carry out the extermination of disease and insect pest to retrieve crop yield loss.In recent years, the harm of insect pest on crops such as paddy rice, fruit tree, vegetables, flowers and diversified economy crop is more and more serious, and because the agricultural chemicals abuse makes insect also more and more serious to the resistance that agricultural chemicals produces, causes pest controling effect to reduce year by year.Therefore, the pesticide species that needs better pest controling effect.
Nitenpyram belongs to the nicotimine class, is another novel product of exploitation after Imidacloprid, pyridine worm miaow, has remarkable interior absorption, osmosis, wide, the no poisoning of safety of insecticidal spectrum.Be the regeneration product of control sucking pest such as trialeurodes vaporariorum, aphid, pear sucker, leafhopper, thrips, the lasting period can reach about 14 days.
Pyridaben is wide spectrum, tagging property miticide, can be used for preventing and treating multiple food vegetalitas evil mite.To whole growth phase of mite be ovum, young mite, if mite with becomes mite that good effect is all arranged, have tangible speed to kill equally to the one-tenth mite of moving the phase and act on.This medicine is not acted upon by temperature changes, and no matter uses in early spring or autumn, all can reach promising result.
Though the Insecticiding-miticiding combination of one of existing at present many employing Nitenpyrams and pyrrole aphid ketone, Mobucin, Imidacloprid, Buprofezin isoreactivity composition, not seeing has Nitenpyram and the two insecticide acaricide composition report as active component of pyridaben.
The inventor finds unexpectedly, and Nitenpyram and pyridaben be composite to have synergistic function.
Summary of the invention
The objective of the invention is the Nitenpyram that the mechanism of action is different, pyridaben and carry out composite a kind of efficient, low toxicity, quick-acting is good and the lasting period is grown the insecticide acaricide composition of providing.The invention is characterized in: with Nitenpyram and pyridaben is active ingredient, and the ratio of quality and the number of copies of Nitenpyram and pyridaben is 20:1～1:20, and all the other are to allow in the agricultural chemicals to use and the acceptable auxiliary element.
Composition pesticide of the present invention can adopt known method to be prepared into suitable agricultural and go up any one formulation of using, and reasonable formulation is aqueous emulsion, wetting powder or water dispersible granules.
The auxiliary agent that uses in the present composition comprises that solvent, dispersant, stabilizing agent, emulsifier, antifreezing agent, thickener etc. and other are of value to active ingredient stablizes and bring into play drug effect in preparation known substance; All be the various compositions of using or allow use in the pesticidal preparations always; Do not have special qualification, concrete composition and consumption require to confirm through simple test according to prescription.
Product described in the invention can finished product preparation form provide, promptly each material mixes in the composition, the form that the composition of composition also can single agent provides, and directly in jar or bucket, mixes before the use, is diluted to needed concentration then.The frequency of administration of the present composition and amount of application change with weather condition and crop state variation, can reach the purpose of control through using suitable formulation.
The present composition can be widely used in various pests such as the aphid, plant hopper, thrips, aleyrodid, two spotted spider mite of crops such as control vegetables, paddy rice, fruit tree.
Compared with prior art, beneficial effect of the present invention is: 1, two kinds of active ingredient is composite has an obvious synergistic effect, has improved control efficiency; 2, enlarged the control spectrum; 3, two kinds of active ingredients are composite, and there is not cross resistance in mechanism of action uniqueness, reduced the agricultural chemicals usage amount, thereby reduced cost and reduced the pollution to environment, and it applies huge economic benefit and social benefit.
Embodiment
In order to make the object of the invention, technical scheme and advantage more short and sweet, the present invention describes with following specific embodiment, but the present invention only limits to these examples absolutely not.The following stated is merely the present invention embodiment preferably, only is used to describe the present invention, can not be interpreted as the restriction to scope of the present invention.Should be pointed out that all any modifications of within spirit of the present invention and principle, being made, be equal to 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 accompanying claims.
Biologicall test embodiment 1:The composite Toxicity Determination of Nitenpyram and pyridaben to panonychus citri.
Subjects: panonychus citri, indoor feeding, well-grown, resistance level is moderate.
Test method: the oranges and tangerines blade is cut into 3cm * 3cm small pieces, puts into the culture dish that diameter is 9cm, be lined with filter paper in the ware.Behind soup of oranges and tangerines foliage-spray, the upset blade also connects 20 larvas, sprays once again, and each spray amount is 10ml, establishes the clear water contrast.1d, 3d, 5d, 10d, 20d check death condition after handling.Every processing repetition 3 times is handled in the spray tower again.
Test medicine adopts the former medicine of 95% Nitenpyram, and the former medicine of 97.7% pyridaben is mixed with required preparation by research and development centre of Guangdong Zhongxun Agricultural Technology Co., Ltd..
According to survey data, calculate the corrected mortality that each is handled.And adopt the abundant method of Sun Yun to calculate the co-toxicity coefficient (CTC value) of mixture with reference to NY/T1154.1-2006.If contrast lethality＜5% is not proofreaied and correct; The contrast lethality is proofreaied and correct between 5%-20%; Contrast lethality＞20%, test need be reformed.The analysis of experimental data method adopts the new multipole difference analysis of Duncan processing method.Result of the test is with reference to table 1.
Table 1, the different proportionings with pyridaben of Nitenpyram are to the virulence of panonychus citri.
Calculate the toxicity index of each medicament and the co-toxicity coefficient (CTC value) of mixture according to the abundant method of Sun Yun, when CTC≤80 are antagonism, 80 ﹤ CTC ﹤ 120 are summation action, and CTC>=120 are synergistic effect.Can know that according to table 1 Nitenpyram and pyridaben are between 20:1～1:20 at compound proportion, have obvious synergistic effect.
Composition pesticide of the present invention can be processed agricultural with known method and go up any one formulation of using, and reasonable formulation is aqueous emulsion, wetting powder or water dispersible granules.Below describe with specific embodiment.Percentage in all prescriptions is mass percent.The various preparation processing technologies of the present composition are prior art, can change to some extent according to different situations.
