Description
Technical field
The present invention relates to a kind of agricultural insecticide composition with synergistic effect, active ingredient is spiral shell worm ethyl ester and be selected from one or more of amide-type insecticide.
Background technology
The suckings pest such as aphid, plant hopper, thrips, scale insect have short, the feature such as breeding amount is large, generation overlap is obvious of breeding cycle, are easy to develop immunity to drugs.Owing to using in a large number year after year, above-mentioned insect has produced serious resistance for the medicament such as Imidacloprid, Acetamiprid.
Spiral shell worm ethyl ester, English name Spirotetramat, is the tetronic acid insecticides of Bayer company research and development, belongs to similar compound with insecticidal/acaricidal agent spiral shell mite ester and Spiromesifen.Spiral shell worm ethyl ester has unique function Characteristics; there is good two-way interior suction conductive performance, can in whole plant corpus, upwards move down, arrive at blade face and bark; the interior absorption of this uniqueness can be protected newborn stem, leaf and root, prevents ovum and the larval growth of insect.Its another one feature is that the lasting period is long, and the effective control that reaches 8 weeks can be provided.Spiral shell worm ethyl ester can effectively be prevented and treated various suckings pest, as aphid, plant hopper, thrips, mealybug, aleyrodid and scale insect etc.Applicable chief crop comprises, tealeaves, soybean, oranges and tangerines, tropical fruit tree, nut, grape, lupulus, potato and vegetables etc.Research shows that it has good selectivity to important beneficial insect as ladybug, syrphus fly and parasitic wasp.But the long-term use separately of spiral shell worm ethyl ester is easily developed immunity to drugs, and cost accounting is higher.
Within 1998, Japanese agricultural chemicals company develops after first compound Flubendiamide that acts on target ryanodine receptor, and E.I.Du Pont Company on its basis, taking Flubendiamide as guide, successively develops a new class lead compound Rynaxypyr.Due to this two compounds structural similarity, the mechanism of action is identical, broad-spectrum high-efficiency and low-toxicity, Ge great research institution carries out ryanodine receptor insecticide research initiative, has formed this several insecticides: phthalic diamides, adjacent formamido benzamides, diamide, adjacent heterocycle benzamides agrochemical.
The amide-type insecticide that the present invention mentions is selected from one or more in Rynaxypyr, fipronil bisamide, thiophene insect amide, Flubendiamide, fluorine worm benzamide, chlorantraniliprole, cyanogen insect amide, Tolfenpyrad.

Embodiment
Spiral shell worm ethyl ester proportioning co-toxicities different from amide-type insecticide
1.1 reagent agent
The former medicine of 95% spiral shell worm ethyl ester, the former medicine of 95.3% Rynaxypyr, above-mentioned former medicine provides by research and development centre of Qingdao Hailir Pesticides and Chemical Co., Ltd..
1.2 for examination worm source
Indoor potted plant cabbage seedling is raised the cabbage aphid three generations adult in 10 generations, temperature (25 ± 2) continuously
oc, relative moisture 50% ± 4%, periodicity of illumination 1 4/1 0 h (L/D).
1.3 single dose assay methods
Adopt dip method that two former medicines are all used to a small amount of acetone solution, then be diluted to into the solution of 5 concentration of equal difference with 0.1% Tween solution, be diluted in beaker with for subsequent use, and with clear water in contrast.Three generations's cabbage aphid adult of the same size is flooded to 5S in the liquid that soaks worm cage, be placed in the culture dish that diameter is 9 c m after sucking unnecessary liquid, in ware, be placed with fresh cabbage leaves and add a cover.Every concentration is processed 10, repeats 4 times.If blank.In (27 ± 1) DEG C illumination box, keep checking lethality after 24 h, it is dead touching polypide nonresponder by pulling needle.Lethality Abbott formula correction, then according to concentration logarithm---lethality probit value is analyzed (Bliss) method, obtains virulence regression equation and puts dead middle amount LC
50value.
The joint toxicity measuring method of 1.4 different proportionings
According to the toxicity test result of single dose, be 10% quality than spiral shell worm ethyl ester by active ingredient: Rynaxypyr is respectively 9:1,7.5:2.5,5:5,2.5:7.5,9:1.Adopt above-mentioned 1.3 methods to carry out toxicity test, calculate LC
50, and press the abundant method of Sun Yun and calculate co-toxicity coefficient (CTC).Co-toxicity coefficient CTC, computing formula is as follows: (taking spiral shell worm ethyl ester as standard medicament, its toxicity index is 100):
The LC of toxicity index (TI)=spiral shell worm ethyl ester of Rynaxypyr
50the LC of/Rynaxypyr
50× 100
The LC of actual toxicity index (ATI)=spiral shell worm ethyl ester of M
50the LC of/M
50× 100
TI × P Rynaxypyr of TTI × P spiral shell worm ethyl ester+Rynaxypyr of theoretical toxicity index (TTI)=spiral shell worm ethyl ester of M
TTI × 100 of the ATI/M of co-toxicity coefficient (CTC)=M of M
In formula:
M be spiral shell worm ethyl ester from Rynaxypyr by the mixture of different proportionings
P Rynaxypyr is Rynaxypyr shared ratio in mixture
P spiral shell worm ethyl ester is spiral shell worm ethyl ester shared ratio in mixture
2.1 toxicity test results
table 1 spiral shell worm ethyl ester (A), the indoor measurement result of Rynaxypyr (B) to cabbage aphid
As can be seen from the table, in the mixture of different proportion, its co-toxicity coefficient is all greater than 120, shows certain synergistic effect, wherein spiral shell worm ethyl ester: the synergistic effect that Rynaxypyr is 5:5 is the most obvious, and co-toxicity coefficient is 198.69.Result of the test shows, under indoor conditions, spiral shell worm ethyl ester, two kinds of medicaments of Rynaxypyr all have higher activity to cabbage aphid, the result of the test of different proportion proportioning shows, by active ingredient spiral shell worm ethyl ester: when Rynaxypyr is 9:1,7.5:2.5,5:5,2.5:7.5,9:1, all show stronger synergistic effect, wherein taking spiral shell worm ethyl ester: Rynaxypyr is during as 5:5, and synergistic effect is best.
