In addition, the invention also provides a pesticide preparation comprising the compound pesticide of p-cymene and limonene and the application thereof.
Description
Technical field
The invention belongs to pesticide field, specifically, the invention provides compound pesticide composition and pesticidal preparations and the application etc. of p-cymene and citrene.
Background technology
Plant extracts is pure natural substance, as botanical pesticide and product, usually has the advantage of safety aspect, but perplexing its problem applied is: 1, its insect resistant effect is very general, and especially compare with many existing agricultural chemicals, its insect resistant effect is much low; 2, wherein complicated component, is not easy stability contorting quality in production, so be difficult to actual applying.

Carrier can be oil-based solvent, comprises vegetalitas grease, as eucalyptus oil, turpentine wet goods, and chemical solvent, as dimethylbenzene, toluene, dimethyl formamide, n-butanol, ethyl acetate, butyl acetate, methyl oleate, fatty acid methyl ester etc.Preferably in the pesticidal preparations of second aspect present invention, described auxiliary material comprises solvent, and more preferably described auxiliary material is solvent.Preferred solvent comprises water and/or alcohol, as ethanol.
In the third aspect, the invention provides p-cymene and citrene is killing the application in harmful pests on plants, wherein the weight ratio of p-cymene and citrene is 4 ~ 20:16 ~ 32; Correspondingly, present invention provides p-cymene and citrene for the preparation of the application killed in the pesticidal preparations of harmful pests on plants, wherein the weight ratio of p-cymene and citrene is 4 ~ 20:16 ~ 32.
Preferably in the application of third aspect present invention, p-cymene and citrene are the composition pesticides of first aspect present invention.Also preferred in the application of third aspect present invention, pesticidal preparations is the pesticidal preparations of second aspect present invention.
Preferably in the application of third aspect present invention, the weight ratio of p-cymene and citrene is 8 ~ 16:20 ~ 28.
More preferably, in the application of third aspect present invention, the weight ratio of p-cymene and citrene is 12:24.
Also preferred in the application of third aspect present invention, insect is two spotted spider mite.
Preferred in the application of third aspect present invention in addition, plant is oranges and tangerines.
Beneficial effect of the present invention is: the composite effect playing the kill pests of Synergistic of p-cymene of the present invention and citrene, even and if Synergistic composite in, also improve the effect of Synergistic further by adjustment proportioning; In composition, composition is simple, is applicable to industrialization and produces, comprise quality testing and control, thus be convenient to actual applying.
For the ease of understanding, below will present invention is described by specific embodiment, it needs to be noted that these descriptions are only exemplary descriptions, do not form limitation of the scope of the invention.According to the discussion of this specification, many changes of the present invention, to change described those skilled in the art be all apparent.In addition, the present invention refer to open source literature, and these documents are to more clearly describe the present invention, and their entire contents is all included in and carried out reference herein, just looks like that repeated description is excessively the same in this article for their full text.

2. test material
Double faced adhesive tape is cut into 2 cm long, be affixed on slide, then collection be pasted on double faced adhesive tape from the citrus red mite of Pujiang County, Sichuan oranges and tangerines with back, avoid adhere its foot, antenna and mouthpart, every sheet pastes 35, put into the container being lined with wet sponge, cover lid, under being placed in the condition of 25 DEG C ± 1 DEG C, microscopy after 2 hours, reject dead and injured individual, remove unnecessary individuality, make each slide there are alive 30.
3. test procedure
Each group of medicament ethanol is dissolved (blank only uses ethanol), and is diluted to different dilution factor with ethanol.Then each slide is dipped in respectively after vibrating gently 5 seconds in each dilution liquid and takes out, unnecessary liquid is sucked with blotting paper, be placed in the white disk being lined with wet sponge, use the covered rearing with plastic film that light transmission is good, be placed in that temperature is 25 DEG C ± 1 DEG C, the photoperiod be L(light): D(is dark) raise under=the condition of 16h: 8h, after process, 24 h, 48 h microscopy respectively, records total borer population and dead borer population.Often kind processes repetition 4 times.
4. data statistics and analysis
4.1 computational methods
According to the data that microscopy obtains, be calculated as follows the corrected mortality (%) of each process relative to blank, and calculate the LC of each medicament with DPS data processing software
50, LC
90and 95% confidence interval, and with LC
50calculate the co-toxicity coefficient (CTC) of each confection to citrus red mite, co-toxicity coefficient (CTC)>=120 is regarded as has synergistic effect; CTC≤80 are regarded as has antagonism; 80 < CTC < 120 regard as has summation action:
In formula: P---lethality; K---represent dead borer population; N---represent the total borer population of process;
In formula: P
1---corrected mortality; P
t---process lethality; P
0---blank lethality.
5. result and conclusion
Result of the test refers to table 1 and table 2.
(24 h) to the test result analysis of citrus red mite for each medicament of table 1
(48 h) to the test result analysis of citrus red mite for each medicament of table 2
Above result shows, p-cymene and citrene composite with weight ratio 4:32 ~ 20:16, all have significant synergistic effect to citrus red mite, particularly p-cymene: during citrene=12:24, synergistic effect is best.
