Abstract
The invention discloses a pesticide mixed preparation. The pesticide mixed preparation comprises the following components in percentage by weight: 0.1-50% of rotenone, 1-60% of pyridaben and the balance of auxiliary agents. The pesticide mixed preparation can be processed into missible oil, wettable powder, suspending agent, microemulsion and emulsion in water, and has the advantages of high quick action, long lasting period and good control effect. Tests prove that the pesticide has obvious control effect on bemisia tabaci on facility-cultivated poinsettia and other flowers, can reduce the toxic action on natural enemies, and is favorable for reducing the influence of chemically synthesized pesticides on ecological environment.
Description
Technical field
The present invention relates to technical field of pesticide, be specifically related to a kind of pesticide mixed preparation.
Background technology
Bemisia tabaci (
Bemisia tabaci) be worldwide insect, extensively invade in recent years global tropical, subtropics and part Temperate Region in China and break out and cause disaster.After 20th century, invaded China the nineties, bamboo telegraph spread, and had become the sociales on various plants.Bemisia tabaci is except directly inhaling harm with the lancet thorn, also drain more honeydew, and propagation various plants virus disease, more specifically that it can cause multiple host plant generation systems physiologic derangement, silver leaf reaction as pumpkin, the inhomogeneous maturations of tamato fruit etc. are brought very large loss to agricultural production.This worm pesticide resistance is strong, generating capacity is large, and control is difficulty comparatively.
Rotenone is a kind ofly to have good desinsection, acaricidal activity from the compound in plant derris root, grey green soy bean blade, degraded very soon in environment, and to natural enemy and other non-target organism safety, shortcoming is unstable, the processing formulation is less.
Pyridaben has another name called pyridaben, pyridaben, is a kind of heterocyclic miticide, is widely used in oranges and tangerines, apple, cotton and vegetables etc. and produces the multiple tetranychid of upper control.Tagging property of pyridaben is strong, and quick-acting is good, if mite ovum, children mite and one-tenth mite are all had outstanding preventive effect.
The applicant finds in the investigation of facility cultivation flowers Bemisia tabaci and control, Bemisia tabaci develops immunity to drugs to polytype insecticide varieties such as organic phosphates, pyrethroid, anabasines, Bemisia tabaci become the Bemisia tabaci such as poinsettia have a liking for anthophagy grass produce in serious problem.In order to seek the effectively preventing medicament, dissimilar pesticide combination is screened, find that pyridaben has control efficiency preferably with the mixed combination of rotenone to Bemisia tabaci, enlarged the control spectrum of two single doses, the combination that is mixed had both kept the advantage of biopesticide, had improved again quick-acting and lasting effect, delayed the Bemisia tabaci pesticide resistance, reduce the chemical pesticide usage amount, alleviated the pollution to environment.
Summary of the invention
The object of the invention is to according to the deficiencies in the prior art, a kind of pesticide mixed preparation is provided, said preparation is by the rational mixture between rotenone and pyridaben, the expanding prevention spectrum improves drug effect, delays the pesticide resistance of Bemisia tabaci, reduce the chemical pesticide usage amount, alleviate the pollution to environment.
Above-mentioned purpose of the present invention is achieved by the following technical programs:
A kind of pesticide mixed preparation comprises the component of the following meter of percentage by weight: rotenone 0.1 ~ 50%, and pyridaben 1 ~ 60%, surplus is auxiliary agent.
As a kind of preferred version, above-mentioned pesticide mixed preparation comprises the component of the following meter of percentage by weight: rotenone 0.5 ~ 15%, and pyridaben 4.5 ~ 30%, surplus is auxiliary agent.
The present invention described rotenone can be former medicine, contain one or more of the plant extracts of rotenone or rotenone preparation, using when multiple, total usage amount can not be greater than the maximum of deal.
Pyridaben of the present invention can be former medicine and/or preparation, and when use was multiple, total usage amount can not be greater than the maximum of deal.
Pesticide mixed preparation of the present invention can prepare by conventional method becomes any suitable actual formulation of using, such as missible oil, wetting powder, suspending agent, microemulsion or aqueous emulsion etc.
Compared with prior art, the present invention has following beneficial effect:
1. after rotenone and pyridaben are mixed, the slow shortcoming of rotenone speed of action can be overcome, the biopesticide advantage of mixture can be kept again, and can widen the scope of application of medicament, extend the lasting period, improve drug effect, control and the resistance management of Bemisia tabaci played an important role;
2. after rotenone and pyridaben were mixed, the dosage of mixture reduced, and had reduced production cost when drug effect improves;
3. due to compatibility and the reasonable mixture ratio of preparation mixture, can greatly reduce the toxic action to various natural enemies, be conducive to alleviate the impact on environment.

The composition that embodiment 11 has an insecticidal activity is killed the laboratory test results of Bemisia tabaci
Adopt the method for conventional biologicall test to measure rotenone, pyridaben and mixture thereof to the virulence of flowers and vegetables Bemisia tabaci adults, and estimate its synergistic effect with co-toxicity coefficient, this example adopts following methods to carry out:
Transplant the poinsettia seedling to flowerpot in May, 2010, adopts the conventional method management, during adopt and control provenance and yellow plate trapping method is controlled Bemisia tabaci quantity in the greenhouse, Growth of Poinsettia is normal, carries out indoor virulence test November in the same year.The 2nd, clip poinsettia seedling top true leaf breaks into the disk of 20mm with card punch with it.Disk is immersed 10s in the series concentration liquid, take out and to be placed on Indoor Natural and to dry (approximately 1h), then single disk face down is layered in the flat glass dactylethrae of diameter 20mm and (pours in advance
13mg/LAgar 3-5mm thick, with moisturizing).Draw consistent Bemisia tabaci adults 25-35 head (regardless of male and female) of puberty with glue head dropper, beat in gently in pipe, then seal with preservative film, with 10-20 aperture ventilation of insect pinprick, the situation of adult in access tube after 1 hour, connect the worm sum if own death is not counted in, then dactylethrae is inverted on the rack for test tube that is lined with gauze, then be placed in the climatic cabinate of 26 ℃ of temperature, relative moisture 60% left and right, illumination 14:10 (L:D).Check the Bemisia tabaci adults death condition after 48h.Touch gently polypide with dissecting needle, motionless person is considered as death.Calculate toxicity regression line and LC50 value and 95% confidence limit with dead probit analysis.

| Rotenone: pyridaben (1:100) | Y=3.5701+1.5262x | 8.65 | 0.9935 | 116.54 |
As can be seen from Table 2, each proportioning of rotenone and pyridaben is mixed to the Bemisia tabaci adults co-toxicity coefficient all greater than 100, shows that rotenone and pyridaben rational mixture have synergistic effect. and wherein rotenone and pyridaben proportioning are that 1:5 and 1:9 synergistic effect are apparently higher than other proportionings.
The test of pesticide effectiveness of embodiment 12 rotenone and pyridaben mixed insecticide preparation
The test of pesticide effectiveness is in green house chamber, the Panyu District of Guangzhou City Zhong Cun farm Bemisia tabaci serious poinsettia (kind: carry out gold medal) that causes harm.2.5% rotenone emulsifiable solution, 15% pyridaben missible oil, 30.3% rotenone+pyridaben wetting powder, 20.0% rotenone+% pyridaben micro-emulsion, 30% rotenone+pyridaben aqueous emulsion, 25% rotenone+pyridaben missible oil are made into dilution to carry out Bemisia tabaci spraying and processes, and before medicine and after medicine, there are the situation of living in 1 day, 3 days and 7 days investigation Bemisia tabaci and calculate control efficiency.
