Embodiment Construction

[0028] The following examples describe the present invention in further detail.

[0029] The environment-friendly insecticide synthesized by using the oleander extract of the present invention comprises the active ingredient of the oleander, which is the oily extract obtained by soaking and extracting the crushed leaves of the oleander. The following experiments are used to compare the insecticidal effects of insecticides using water as a solvent, insecticides using ethanol as a solvent, and water as a control group.

[0030] The tested pests were apple snails, millipedes, and poisonous moths, all of which were collected from the lake area of ​​the East Campus of Huzhou Normal University.

[0031] Fresh and healthy oleander leaves are collected from the oleander plant in the lake area of ​​the East Campus of Huzhou Teachers College.

[0032] The main chemicals and reagents are shown in Table 1:

Abstract

The invention discloses an environmentally-friendly pesticide synthesized by utilizing oleander extract. The environmentally-friendly pesticide comprises an oleander active ingredient which is oily extract obtained by soaking and extracting oleander broken leaves. The solvent of the pesticide is water or an ethyl alcohol solution; the concentration of the oleander active ingredient is 100mg / L to 600mg / L; ciprofloxacin for corrosion prevention is added in the pesticide. The data analysis indicates that the higher the concentration of the extract liquid of the oleander leaves, the stronger the toxicity. The insecticidal action of the oleander extract liquid is needed to be completed with a certain time, and therefore, the pesticide is a non-quick-acting pesticide, and can be developed and utilized as a slow-release plant source pesticide. The pesticide prepared by the oleander extract disclosed by the invention provides a more effective means for the biological pesticide for comprehensive treatment for the pest and disease damage; the oleander has high killing activity for ampullaria gigas, porthesia similis and diplopod, has simply and easily available materials, and is a very excellent environmentally-friendly pesticide.

Description

technical field [0001] The invention relates to the technical field of biological pesticides, in particular to an environment-friendly insecticide, in particular to an environment-friendly insecticide synthesized by using oleander extract and a preparation method thereof. Background technique [0002] Due to people's emphasis on environmental protection and the strengthening of insect resistance, people's demand for new green and environmentally friendly insecticides is increasing, and their requirements are also getting higher and higher. The use of biopesticides to control certain pests has a long history in our country and is widely used among the people. For example, mugwort fumigation is often used to drive insects in rural summer nights, and deer vine extracts are used to control fruit trees, vegetables, mulberry, A variety of pests such as tea and tobacco and livestock ectoparasites and ticks, mites, use tobacco extract to control aphids, thrips, psyllids, etc. In the ...
