Further, preferably, the weight ratio of described spiral shell worm ethyl ester and gamma cyhalothrin is 20:1 ~ 1:5.
Further, preferably, the total content of described active ingredient is 5%-80%(weight ratio)
Further, preferably, described auxiliary element is chosen following arbitrary or combination: wetting dispersing agent, stabilizing agent, antifreezing agent, emulsifier, thickener, defoamer.
Further, preferably, described Pesticidal combination is the form of suspending agent or aqueous emulsion or microemulsion or missible oil.
The purposes of a kind of Pesticidal combination in sucking pest control.
Further, preferably, described sucking pest is for any below: crop aphid, thrips, wood louse, rice fulgorid, mealybug, aleyrodid and scale insect.
Compared with the prior art, beneficial effect of the present invention is: 1, mixture has significant synergies, and has improved control efficiency, extends the lasting period.2, two kinds of active ingredient mechanism of action differences in composition, compared with using, have reduced the risk that resistance produces with single dose.3, two kinds of active ingredient mixtures, have reduced dosage, have alleviated environmental pollution.
Other features and advantages of the present invention will be set forth in the following description, and, partly from specification, become apparent, or understand by implementing the present invention.Object of the present invention and other advantages can be realized and be obtained by specifically noted structure in write specification, claims and accompanying drawing.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, the present invention describes with following specific embodiment, but the present invention is limited to absolutely not these examples.The following stated is only the good embodiment of the present invention, only in order to explain the present invention, can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that all any amendments of making within the spirit and principles in the present invention, be equal to replacement and improvement etc., within all should being included in protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
Component of the present invention is reasonable, good disinsection effect, and active component spiral shell worm ethyl ester and gamma cyhalothrin have significant synergies, quick-acting is good, lasting effect is long, slows down the generation of resistance, preparation less residue, environmentally safe, good to crop safety, meet the security requirement of pesticidal preparations.
Specifically, described Pesticidal combination, comprises the active ingredient and the auxiliary element that are made up of spiral shell worm ethyl ester and gamma cyhalothrin, and wherein, the weight ratio of described spiral shell worm ethyl ester and gamma cyhalothrin is 30:1 ~ 1:30.
In a preferred embodiment, the weight ratio of described spiral shell worm ethyl ester and gamma cyhalothrin is 20:1 ~ 1:5, and according to test, the insecticidal effect of this ratio is best.
Wherein, further, the total content of described active ingredient is 5%-80%(weight ratio), wherein, described auxiliary element is chosen following arbitrary or combination: wetting dispersing agent, stabilizing agent, antifreezing agent, emulsifier, thickener, defoamer, and auxiliary element belongs to the composition that pesticide field is conventional, is not described in detail at this.

This embodiment is used for preventing and treating apple scale insect, 8.5% spiral shell worm ethyl ester efficient cyhalothrin emulsifiable concentrate is carried out to 500 times of thin up sprayings, after medicine, the control efficiency of 7 days is 90.6%, be greater than the preventive effect of 500 times 73.2% of 8% spiral shell worm ethyl ester, dispenser result shows that 8.5% spiral shell worm ethyl ester efficient cyhalothrin emulsifiable concentrate uses separately synergistic effect obvious than spiral shell worm ethyl ester, gamma cyhalothrin.
The embodiment of the present invention further illustrates application and the beneficial effect of composition with following biologicall test and test of pesticide effectiveness example.
Experiment 1: the toxicity test of spiral shell worm ethyl ester proportionings different from gamma cyhalothrin to cotten aphid
The former medicine that test medicine 95% spiral shell worm ethyl ester adopts Bayer Bitterfeld GmbH crop science company to produce, the former medicine that 95% gamma cyhalothrin adopts Jiangsu Fengshan Group Co to produce, test method is mixed with former medicine with reference to " the agricultural industry criteria NY/T1154.7-2006 of the People's Republic of China (PRC) " test medicine needing.Toxicity test adopts leaf dipping method, will put in people's medicament and soak 5-7s without the cotton seedling of worm, and each concentration is processed 5 of cotton seedlings, not to be treated to blank containing medicament.After moisture evaporation, on every cotton seedling, connect 20 left and right of aptery one-tenth aphid.The cotton shoot root of the band aphid of handling well portion is removed, cotton unrooted seedling is inserted and added in advance in the 200ml beaker of 1/5 medium, beaker mouth seals with gauze in case cotten aphid escapes, and covers culture dish lid in case cotton seedling is wilted too early on gauze again.If aphid toxicity test is 3-4d aphid, becoming aphid is 7d aphid.After processing, examination worm is placed in to illumination box, temperature is controlled at 25 native l DEG C, and relative moisture is 60%-75%, and the photoperiod is 14L:10D.Calculate survival rate and adopt Abbott formula calculation correction lethality, use DPS data handling system to calculate virulence regression equation and LC50, test repeats 4 times.
The co-toxicity coefficient (CTC value) of mixture calculates by following formula:
In formula:
AT1---mixture actual measurement toxicity index;
The LC50 of S---standard insecticide, unit is milligrams per liter (mg/l);
The LC50 of M---mixture, unit is milligrams per liter (mg/l);
TTI=TIA×PA+TIB×PB
In formula:
The theoretical toxicity index of TTI---mixture;
TIA----A medicament toxicity index;
The percentage composition of PA-----A medicament in mixture, unit is percentage;
TIB----B medicament toxicity index;
The percentage composition of PB-----B medicament in mixture, unit is percentage.
In formula:
CTC----co-toxicity coefficient;
AT1---mixture actual measurement toxicity index;
The theoretical toxicity index of TTI---mixture.
The co-toxicity coefficient (CTC) >=120 of built agent shows as synergistic effect; CTC≤80 show as antagonism; 80 < CTC < 120 show as summation action.
