The invention has an advantage that: the invention has the synergism, and can be used to control various agricultural pests, such as the citrus red mite, the citrus rust mite, the apple leaf mite, the two-spotted spider mite, the apple aphids and various pest mites and pests on the fruit tree, the vegetable and other crops.
Description
Technical field
The present invention is dividing an application of Chinese patent application 200510047097.2.
The invention belongs to agricultural insecticidal, miticide field, relate to a kind of Insecticidal and acaricidal agent composition that contains the dual-active component of butyl ether urea.
Background technology
The butyl ether urea is a kind of Thiourea Insecticidal and acaricidal agent, is mainly used in insects such as phytophagous mites on control multiple field crops, fruit tree, vegetables and the ornamental plants and diamond-back moth, noctuid.
English common name: the diafenthiuron of butyl ether urea, chemical name: 1-tertiary butyl-3-(2,6-diisopropyl-4-Phenoxyphenyl) thiocarbamide.Structural formula is as follows:
Often there is defective in various degree in the Insecticidal and acaricidal agent kind that contains the single-activity component on pest, control of pest mite: use insect, evil mite to be easy to generate pesticide resistance continuously, access times cause the pollution grows worse of environment etc. more.And being mixed into the blending ingredients Insecticidal and acaricidal agent, the Insecticidal and acaricidal agent by two or more active component can effectively overcome above shortcoming.Simultaneously, utilize two kinds of synergistic effects that active component is mixed and is produced, can improve preventive effect, reduce the consumption of active ingredient, save cost, delay insect, the drug-fast generation of evil mite, and reduce pollution environment.Some contains the existing report of Insecticidal and acaricidal agent composition of butyl ether urea dual-active component, and for example Chinese patent CN1238661A and CN1557159A disclose the synergistic effect of the Insecticidal and acaricidal agent composition of butyl ether urea and fluorine azoles worm nitrile and butyl ether urea and pyridaben composition respectively.But, do not see the report of the Insecticidal and acaricidal agent composition that butyl ether urea and alkynes mite spy, azacyclotin or fluorine worm nitrile are formed so far.
Summary of the invention
In order to satisfy the needs of agricultural production, make full use of two kinds of active components be mixed the synergistic effect that produced, improve preventive effect, reduce agricultural cost and delay insect, the drug-fast generation of evil mite, the present invention proposes a kind of new Insecticidal and acaricidal agent composition: said composition contains two kinds of active components of A, B, component A is selected from the butyl ether urea, and B component is selected from alkynes mite spy, azacyclotin or fluorine worm nitrile.
Alkynes mite spy is a kind of miticide, but Panonychus citri genus on effectively preventing and treating apple-tree, cotton, cucumber, grape, golden hop, corn, nut, soybean, drupe, tomato and the vegetables etc. and Tetranychus and food planting property mite class widely.Special English common name: the propargite of alkynes mite, chemical name: 2-(4-tert-butyl benzene oxy) cyclohexyl Propargyl sulfite.
Structural formula:
Azacyclotin is a kind of tagging property miticide, and to all movable periods of planting property of food mite class, larva and adult all have preventive effect.Be used for citrus, cotton, fruit, grape, vegetables and other crops.English common name: the azocyclotin of azacyclotin, chemical name: three (cyclohexyl)-1H-1,2,4-triazol-1-yl tin.
Structural formula:
Molecular formula: C
20H
35N
3Sn, molecular weight: 436.2
Fluorine worm nitrile is that a kind of tool is tagged, the novel pesticide of stomach toxicity, systemic action, and insecticidal spectrum is wide, and a series of important pests such as Lepidoptera and coleoptera are had very high insecticidal activity.English common name: the fipronil of fluorine worm nitrile, chemical name: (RS)-5-amino-1-(2,6-dichlor-4-trifluoromethyl phenyl)-4-trifluoromethyl sulfinyl pyrazole-3-nitrile.
Structural formula:
After mixing, two kinds of Insecticidal and acaricidal agent active components show three kinds of type of action usually, i.e. synergistic effect, summation action and antagonism.The bright employing of this law Sun Yunpei (Sun Y-P) method by calculating co-toxicity coefficient, is estimated and is used effect with.This is that those skilled in the art is estimating the evaluation criterion that two kinds of mixed interactions of Insecticidal and acaricidal agent active component are adopted usually.Co-toxicity coefficient obviously is synergistic effect greater than 100, and co-toxicity coefficient is significantly less than 100 and is antagonism, and co-toxicity coefficient=100 are summation action.
Computing formula:
The content (%) of A in the TI * mixture active ingredient of theoretical toxicity index (the TTI)=A agent of mixture
The content (%) of B in the TI of+B agent * mixture active ingredient
Find by the test of indoor biological activity determination, contain above-mentioned A, two kinds of active component Insecticidal and acaricidal agents of B composition, be about to the butyl ether urea and mix in certain proportion to use with alkynes mite spy, azacyclotin or fluorine worm nitrile respectively and have the notable synergistic effect.
According to the bright technical scheme of this law, the suitable proportion of A, two kinds of active components of B is 1: 99 to 99: 1 based on the parts by weight of active component.The active component weight percentage is 1%～99% in the composition.
More preferably scheme is: the ratio of A, B two components is 1: 49 to 49: 1 based on the parts by weight of active component.
Further preferred scheme is: when the B component was selected from alkynes mite spy or azacyclotin, the ratio of A, B two components was 1: 10 to 10: 1 based on the parts by weight of active component.When the B component was selected from fluorine worm nitrile, the ratio of A, B two components was 1: 1 to 49: 1 based on the parts by weight of active component.
