Abstract
The invention relates to a pesticide composite containing pyrone and used for preventing and treating cabbage aphides. The pesticide composite comprises the effective quantity of 5-(4-biphenyl)-2H-pyrane-2-ketone and carriers acceptable in pharmacy. The pesticide composite containing the pyrone and used for preventing and treating the cabbage aphides is good in preventing and treating effect and suitable for being popularized on a large scale in fields.
Description
Technical field
The present invention relates to pesticide field, specifically, the present invention relates to a kind of composition pesticide of the control cabbage aphid containing pyrones.
Background technology
Cabbage aphid (Brevicoryne brassicae (Linnaeus)), there are 8 ~ 10 generations in year, generation overlap.With hibernate of ovum, mainly on late wild cabbage, be secondly kohlrabi, the winter radish and winter Chinese cabbage on.Also parthenogenesis can be sought all the year round in warm area.Hibernating egg generally starts hatching in April in next year, first in breeding harm in strain of reserving seed for planting, in 5 months, the last ten-days period move on spring vegetable and endanger, expand on summer vegetable and autumn vegetable again, namely start October to produce sexuale, mating is laid eggs and to be survived the winter in the dish strain of reserving seed for planting or preserve, if minority becomes aphid and aphid also can survive the winter in clamp.Cabbage aphid causes great harm for the plantation of the vegetables of wide geographic area.
Summary of the invention
The object of the present invention is to provide a kind of composition pesticide of the control cabbage aphid containing pyrones.
In order to realize object of the present invention, the invention provides a kind of composition pesticide of the control cabbage aphid containing pyrones, including 5-(4-the xenyl)-2H-pyran-2-one of effective amount and pharmaceutically acceptable carrier.
Preferably, described composition pesticide can be spray, emulsion or pulvis.
The composition pesticide of the control cabbage aphid containing pyrones of the present invention has good control efficiency, is suitable in field large-scale promotion.
Embodiment
Below by way of the description of embodiment, the invention will be further described, but this is not limitation of the present invention, those skilled in the art are according to basic thought of the present invention, various amendment or improvement can be made, but only otherwise depart from basic thought of the present invention, all within the scope of the present invention.
Experimental example
In vegetables experimental field, cultivation condition is outdoor cultivation.This experimental field physical features is smooth, light loam matter, better-than-average fertility, soil pH value 7.8, the content of organic matter 1.65%, and irrigation and drainage are convenient, and managerial skills are higher, wild cabbage growing way uniformity.During test, wild cabbage is the heading stage, and aphid moderate occurs, and take cabbage aphid as sociales, average hundred strains have worm about 1300.
5-(4-xenyl)-2H-pyran-2-one precise under sensibility reciprocal 0.1mg balance, adopt organic solvent-acetone to dissolve, and constant volume becomes the mother liquor of 1mgl/mL.
Blade infusion process joins in the distilled water containing 0.1% Tween-80 with mother liquor when measuring respectively, is diluted to the liquid of different pesticide concentration, and with the distilled water adding Tween-80 and a small amount of solvent acetone in contrast.
During topical application method, mother liquor take acetone (containing 20% distilled water) dilution as the liquid of variable concentrations.
Toxicity test method: adopt drop method to carry out.
Drop method: test adopts micro intravenous drip device by liquid drop on the mesonotum of every examination worm, often process 30 larvas, 5 dosage established by often kind of medicament, take acetone as contrast, often process and repeat for 3 times, process after examination worm raise with wild cabbage, then put into 26 DEG C ± 2 DEG C, relative moisture be 80% culturing room normally cultivate, check result after 48h.
Joint toxicity measuring: adopt the mutual determination method of Horsfall to carry out proportioning screening, with two single dose LC on the basis that single dose measures
50.Concentration preparating liquid, by not carrying out mixed determining on year-on-year basis, virulence ratio is calculated according to actual and expected mortality, select the proportioning that wherein virulence ratio is higher, being scaled different active constituent content respectively carries out composite, then be diluted to variable concentrations to measure with drop method, processing method is the same.
Measurement result is investigated: examination worm process 48h " Invest, Then Investigate " respectively processes dead borer population, calculates lethality, goes out corrected mortality when contrast lethality is greater than 5% by A bbott formulae discovery.
The LC of agricultural chemicals of the present invention
50be 7.32 (mg/L).
