Abstract
The invention discloses an insect-killing composition containing pymetrozine and etofenprox, comprising the effective active components of the pymetrozine and the etofenprox, wherein the weight ratio of the pymetrozine to the etofenprox is 1:2-3:1. The invention has reasonable components, good insect-destroying effect, low application cost, high quick-acting property, long lasting period and good safety without pollution on crops, little residual quantity of a preparation and obvious synergistic action, delays the generation of resistibility, and conforms to the safety requirement of a pesticide preparation; and the activity and the insect-killing effect of the invention are not the simple superposition of the activity of the components. The invention has the preventing effect of 84.24-96.22% to paddy rice planthopper after being applied 14 days.
Description
Technical field
The present invention relates to a kind of Pesticidal combination, particularly Pesticidal combination and the application thereof be made up of pyrrole aphid ketone and ether chrysanthemum ester of effective active composition belongs to technical field of compounded pesticide.
Background technology

3) be a kind of insecticide of similar pyrethroid, have that insecticidal spectrum is wide, insecticidal activity is high, the speed of knocking down is fast, the lasting period is long, less to natural enemy lethality such as paddy field spiders, to advantages such as crop safeties.Have and tag and stomach poison function, do not inhale conduction in insect is not had.Be widely used on paddy rice, vegetables, the cotton, various pests such as Lepidoptera, Semiptera, orthoptera, coleoptera, diptera and Isoptera are had efficiently.But in actual application, use the agent of ether chrysanthemum ester list separately, insect is prone to produce resistance, and use cost rises day by day.
At present, be that the pesticidal preparations of effective ingredient is main with 25% pyrrole aphid ketone wetting powder with pyrrole aphid ketone, in actual use, the lasting period is long; But quick-acting is relatively poor, and ether chrysanthemum ester quick-acting is better, to crop safety; The unexpected discovery of inventor is mixed two active components to use and can improves its quick-acting, is arranged, significantly synergistic effect the lasting period preferably again; Can reduce the pharmacy application amount, save cost, the generation that slows down pest resistance.
Summary of the invention
One of the object of the invention is to provide a kind of good disinsection effect, and drug cost is low, the Pesticidal combination that contains pyrrole aphid ketone and ether chrysanthemum ester that is difficult for developing immunity to drugs.
Another object of the present invention is to provide the purposes of above-mentioned composition.

Biological Examples 3: prevent and treat the rice hoppers indoor virulence test
In order to prevent and treat the rice fulgorid in the agricultural production, the inventor has carried out mutual composite synergy research with ether chrysanthemum ester, pyrrole aphid ketone effective active composition.It is tested object that rice fulgorid is adopted in test, and concrete grammar is:
1) the former medicine of rice fulgorid (brown planthopper Nilaparvata lugens) test medicine ether chrysanthemum ester adopts the former medicine of Mitsui KCC production, the former medicine that the former medicine of pyrrole aphid ketone adopts Jiangsu Anpon Electrochemical Co., Ltd. to produce.By technology department of Shanggezhilu Biosciences Co., Ltd., Shaanxi former medicine is mixed with the test medicine that needs, test method is with reference to " the agricultural industry criteria NY/T1154.7-2006 of the People's Republic of China (PRC) ".At first single agent and each Mixed Pharmacy are provided with 5 variable concentrations gradient: 12.5g/ug, 25g/ug, 50g/ug, 100g/ug, 200g/ug.The examination worm be rice fulgorid (brown planthopper) pupa that picks up from the field, the water rice seedling raised for 3 generations in the greenhouse, select uniformity four age nymph; Be pressed into the culture dish of putting rice seedling (with the cotton ball processing of preserving moisture) diameter 12cm, every ware connects and anaesthetizes 30 of nymphs, and every processing connects 4 culture dishes; Spray under 50PSI pressure with the potter spray tower, spray a ware at every turn, every ware spraying liquid 3ml; After treating that insect revives; The culture dish of handling is put into the 12H/12H illumination box cultivate, checked dead borer population in 72 hours, calculate lethality.Blank spray equivalent clear water.Carry out statistical analysis with DPS data processor software, calculate the LC of each medicament
50Value is estimated the activity of confession reagent agent to the examination worm with this.
The co-toxicity coefficient of mixture (CTC value) calculates by following formula:
In the formula: ATI---mixture actual measurement toxicity index;
S---standard insecticide LC
50, unit is every liter (mg/L) of milligram;
The LC of M---mixture
50, unit is every liter (mg/L) of milligram;
TTI＝TI
A×P
A+TI

P
B---the percentage composition of B medicament in mixture, unit are percentage (%);
In the formula: CTC---co-toxicity coefficient;
ATI---mixture actual measurement toxicity index;
The theoretical toxicity index of TTI---mixture;
2) rice fulgorid mensuration result sees table 3 respectively.
Table 3 different disposal is to the toxicity test result of rice fulgorid
