Biology plant pesticides and preparation technique thereof

Abstract

The invention belongs to the pesticide field, which more particularly relates to a biological botanic insecticide and a preparation technique. The prescription of the biological botanic insecticide is as follows by weight percentage: 0.2-0.6 percent of abamectin; 1.0-3.0 percent of matrine; 3.0-3.5 percent of tripterygium wilfordii; 2.0-2.5 percent of rhododendron molle; 3.0-4.0 percent of grapeleaf anemone; 2.0-3.5 percent of unbracteolated spurge root; 2.5-4.0 percent of derris; 2.5-4.0 percent of stemona; 2.0-3.0 percent of vervain; 1.5-2.5 percent of emulsilier; 0.1-0.3 percent of antiseptic; 2.0-4.0 percent of stabilizing agent; and 65.0-88.2 percent of distilled water. The invention integrates stomachtoxicity, tag and nerve poison into one body. The invention not only has synergistic effect each other, improves the insecticidal efficiency and leads the harmful insect to be difficult to generate drug resistance, but also achieves the target of high efficiency and broad spectrum; the invention is harmless to the plant, has no residue with safe usage, therefore, the environment can be free from contamination.

Description

technical field

[0001] The invention belongs to the field of pesticides, and in particular relates to a biological botanical insecticide and a preparation process. Background technique

[0002] At present, chemical pesticides are still widely used in agricultural production. Due to their high toxicity and high residues, chemical pesticides are easy to produce drug resistance and easily cause environmental pollution, which constitutes a negative impact on a virtuous cycle of ecology. With the development of the economy and the advancement of human civilization, it is an important task for scientific and technological personnel to develop a new generation of high-efficiency, low-toxicity, low-residue, and easy-to-degrade pesticides. Contents of the invention

[0003] The purpose of the present invention is to overcome the defects of high toxicity of chemical pesticides, high residues, easy to produce drug resistance, and easy to cause environmental pollution, and to invent a...

Examples

Embodiment Construction

[0031] The formula of described biological plant source insecticide is as follows by weight percentage:

[0032] Abamectin 0.5

[0033] Matrine 2.6

[0034] Tripterygium 3.0

[0035] Goat flower 2.5

[0036] Wild Cotton 3.5

[0037] Wolfsbane 3.2

[0038] Rovine 4.0

[0039] 100 3.5

[0040] Verbena 2.7

[0041] Emulsifier 2

[0042] Preservatives 0.3

[0043] Stabilizer 4

[0044] Distilled water 68.2

[0045] Described Naoyanghua, wild cotton, chamaejasma, babu, and verbena are realized by the following mixed extraction process: take respectively: 25 kilograms of naoyanghua, 35 kilograms of wild cotton, 32 kilograms of chamaejasma, Babu 35 kg, Verbena 27 kg, these five kinds of raw materials are dried to water content ≤ 5%, evenly powdered to 80 mesh, all put into the extraction tank, add 450 kg of distilled water, heat to make the temperature in the extraction tank rise to After leaching at 95°C for 18 hours, the residue was removed by filtration, and the extrac...
