Embodiment 1

[0033] Take by weighing angelica lactone (25%), butenylphthalide (25%), butylphthalide (25%), ligustilide (10%), castorine (15%) respectively, total 12g, dissolve with 1.4g ethanol solution, add 4.2g Tween, dissolve, according to routine process, make insecticide of the present invention, then add water dilution in prepared insecticide, make the concentration of bulk drug be 15%. Finally, the diluted insecticide was tested for indoor biological activity on aphids, and the method was carried out according to the aphid stem dipping method in the Bioassay SOP of the National Southern Pesticide Innovation Center. After 72 hours, the number of dead and alive insects in each treatment was investigated, and the control effect was 92.8%.

Embodiment 2

[0035] Take by weighing angelica lactone (5%), butenylphthalide (45%), butylphthalide (30%), ligustilide (20%), castorine (0%) respectively, total 15g, dissolve with 20g acetone, add emulsifying agent etc. 18g wherein, according to routine process, make insecticide of the present invention, then add water dilution in prepared insecticide, make the concentration of bulk drug be 2.1%. Finally, the diluted insecticide was tested for indoor biological activity on aphids, and the method was carried out according to the aphid stem dipping method in the Bioassay SOP of the National Southern Pesticide Innovation Center. After 72 hours, the number of dead and alive insects in each treatment was investigated, and the control effect was 78.1%.

Embodiment 3

[0037] Take by weighing angelica lactone (50%), butenylphthalide (50%) respectively, add up to 10g, dissolve with 10g ethyl acetate, add emulsifying agent, synergist, solubilizing agent etc. auxiliary material 2.2g therein, according to Conventional technology is used to prepare the insecticide of the present invention, and then add water to dilute the prepared insecticide so that the concentration of the raw material is 25%. Finally, the diluted insecticide was tested for indoor biological activity on aphids. The method was carried out according to the aphid stem dipping method in the Bioassay SOP of the National Southern Pesticide Innovation Center. The mortality rate was counted after 72 hours, and the control effect reached 100%.

Abstract

The invention provides a compound insecticide for controlling aphids, wherein the compound insecticide comprises, by mass, 0.05-99% of a bulk drug and 1-99.95% of a conventional auxiliary material, and the bulk drug comprises, by weight, 5-55% of Angelica lactone, 2-55% of butylidenephthalide, 0-45% of butylphthalide, 0-25% of Ligustilide, and 0-15% of ricinine. The invention further provides preparation and applications of the compound insecticide. The compound insecticide of the present invention is the lactone compound-containing compound preparation used for controlling aphids and having advantages of high efficiency, no residue, low production cost, economy, practicality, environmental protection and excellent comprehensive performance.

Description

technical field [0001] The invention relates to a preparation in the technical field of agricultural insecticides and a preparation method thereof, in particular to a preparation containing lactone compounds for controlling aphids and its preparation and application. Background technique [0002] Aphids are one of the most destructive pests on earth with a wide distribution. It has the characteristics of heterogeneous hosts, wide distribution, many species, overlapping generations, fast reproduction, and large numbers. Clusters on the back of plant leaves, tender stems, growth points and flowers, sucking plant juice with sharp piercing-sucking mouthparts, causing plant nutrition deterioration, resulting in reduced plant growth rate, stunted growth, leaf spots, yellowing, curling leaves, Different symptoms such as wilting can reduce the yield or even kill it, and it can also spread various plant viruses, causing severe economic losses. [0003] For a long time, chemically s...
