preparation example Construction

[0028] A method for preparing a high-efficiency and low-toxicity botanical pesticide for gardens, comprising the following steps:

[0029] S1: Extracting Zanthoxylum bungeanum fruit extract, Rhizome extract of Chamaejas chamaejasma and Sophora japonica extract with ethyl acetate to obtain fruit extract of Zanthoxylum bungeanum, Rhizome extract of Chamaejas chamaejasma and Sophora japonica extract, and a mixed extract;

[0030] S2: Wash nandina, dried ginger, matrine, eucalyptus, and delphinium and put them into a container for decoction; Glycol and water, stir to obtain mixed filtrate;

[0031] S3: Combine the mixed extract obtained in step S1 and the mixed solution obtained in step S2, add osthole, litsea cubeba oil, ethylene glycol, Bacillus subtilis, and chitosan, mix and stir evenly, and remove the residue after 10-15 minutes Filter to get pesticides.

Abstract

The invention discloses a high-efficiency low-toxicity plant pesticide for gardens and a preparation method thereof. The high-efficiency low-toxicity plant pesticide is prepared from the following raw materials in parts by weight: 16 to 25 parts of bunge pricklyash fruit extracting solution, 8 to 14 parts of stellera chamaejasme rhizome extracting solution, 6 to 11 parts of common nandina rhizome, 7 to 11 parts of cnidium lactone, 3 to 5 parts of emamectin benzoate, 4 to 7 parts of sophora flower bud extract, 2 to 6 parts of rhizoma zingiberis, 15 to 21 parts of sophocarpidine, 7 to 12 parts of resina populi and 6 to 12 parts of delphinium ajacis root or seed. The pesticide disclosed by the invention is prepared from the raw materials of the bunge pricklyash fruit extracting solution, the stellera chamaejasme rhizome extracting solution, the common nandina rhizome, the cnidium lactone, the emamectin benzoate and the like according to effective matching. The pesticide has the advantages of simple preparation method and composition, obvious injurious insect killing effect, no residue, no pollution to soil, water sources and crops, degradation in natural environment and no harm to human and livestock; furthermore, the injurious insects are prevented from generating drug resistance; the pesticide is prepared from the natural raw materials, so that the pesticide self has no toxicity, can be directly applied to flowers and has no effect on the flowers self; a pesticide effect is durable, and an insect killing effect is good.

Description

technical field [0001] The invention relates to an insecticide, in particular to a high-efficiency and low-toxic botanical pesticide for gardens and a preparation method thereof. Background technique [0002] At present, the pests and diseases of crops are controlled by chemical pesticides, and the use of chemical pesticides can easily cause pests to develop resistance and reduce the insecticidal effect of pesticides. At the same time, chemical pesticides remain in crops and enter the human body through the food chain, posing a threat to human health. In order to solve the above disadvantages, the present invention selects several plants capable of preventing and killing diseases and insect pests as raw materials, and develops a pollution-free plant insecticide and a preparation method thereof. [0003] The growth and development of flowers requires careful care. The existence of pests and germs will cause harm to the growth and flowering of flowers, affecting their ornamen...
