Problems solved by technology

[0002] Existing insecticides are mostly made of chemicals with different effects and long residual period. Although they can prevent agricultural and forestry diseases and insect pests in a short period of time, they have caused serious harm to crops, especially human bodies, for a long time.
The use of pesticides, because they contain a large amount of chemical substances, has brought more or less pollution to the air, water, soil and food after a large amount of application. At the same time, long-term consumption of chemical pesticides will also make pests resistant to pesticides.
[0003] When pesticides are applied to crops, vegetables or fruit trees, the pesticides remaining on the surface of the crops, due to their strong fat solubility, can easily penetrate into the waxy layer of the crop epidermis, making it difficult to completely wash off

Embodiment 1

[0017] The biological insecticide containing brucei is prepared by weight proportion by using the following raw materials: 10% of Astragalus, 35% of purslane, 25% of brussulae, 10% of myrtle root, 8% of jasmine root, 6% of amino acids, Curcuma Oil 2%, Colloidal Silicon Dioxide 4%.

[0018] The preparation method includes the following steps:

[0019] (1) Add 4 times the weight of water of brussae pear, root of jasmine root and jasmine root, decocted for 4 times, filter after each boil, collect and mix the filtrate, and concentrate the mixture into a paste;

[0020] (2) After smashing the whole grass of A. japonicus, add 40-45 ℃ water, the amount of water added is 3 times of the total weight of A. japonicus, stir for 10 minutes, and then filter the residue to obtain A. japonicus liquid.

[0021] (3) After mashing the purslane, add 3 times the volume of water, decocting once, and collect and mix the filtrate;

[0022] (4) Add the paste obtained in the step (1), the Aloe vera l...

Embodiment 2

[0025] A kind of bio-insecticide containing brucei uses the following raw materials to prepare by weight ratio: 22% of Astragalus, 15% of purslane, 35% of brussae, 5% of myrtle root, 15% of jasmine root, 4 of amino acids %, Curcuma oil 1%, Sodium carboxymethyl cellulose 3%.

[0026] The preparation method includes the following steps:

[0027] (1) Add 5 times the weight of water of Brassica chinensis, root of jasmine root and root of jasmine, decocted 4 times, filter after each cooking, collect and mix the filtrate, and concentrate the mixture into a paste;

[0028] (2) After smashing the whole plant, add water at 40-45°C, the amount of water added is 3 times the total weight of the plant, stir for 15 minutes, and then filter the residue to obtain the extract.

[0029] (3) After mashing the purslane, add 3 times the volume of water, decocting for 2 times, and collect and mix the filtrate;

[0030] (4) Add the paste obtained in the step (1), the Aloe vera liquid, the curcuma ...

Embodiment 3

[0033] Cabbage and tomato were potted in net cages, cabbage cages were artificially inoculated with cabbage worms, and tomato cages were artificially inoculated with whitefly. The simple mixed solution of each solution of the raw materials in the invention was used as control group 1. The 40% acetamiprid water dispersant provided by the company is the control group 2. Compared with the pesticides prepared in Example 1 and Example 2, the experiment was carried out 3 days after inoculation, and the foliar spray was carried out after diluting 300-600 times. It is advisable to spray completely on the foliar surface, respectively observe and count the coverage density of pests before application and the coverage density of 1-4 days after application, and obtain the following data:

[0035] Table 1

[0036] As can be seen from the data in Table 1, the simple mixing of raw materials can play a certain insecticidal effect, but the insecticidal effect is relatively weak. T...

Abstract

The invention discloses biological insecticide containing brucea javanica. The biological insecticide is prepared from 10%-25% of hairyvein agrimony, 5%-40% of purslane, 10%-35% of the brucea javanica, 5%-20% of downy rosemyrtle root, 8%-15% of arabian jasmine root, 2%-8% of amino acid, 1%-4% of oil of zedoary turmeric and 2%-4% of suspending agent. Compared with the prior art, the biological insecticide has the following advantages that according to the special effects of the brucea javanica, various plant effective constituents are matched to be supplementary with the brucea javanica, and thus the purposes of pest prevention and killing are achieved through the touch killing function, the stomach toxicity function, the food refusal function and the pest growth and development inhibition function; the advantages of being fast to take effect and high in potency are achieved; meanwhile, no harm is caused to crops, and the phenomenon that human health is affected due to pesticide residues can be further avoided.
