Problems solved by technology

Current studies have shown that petrin has a variety of pharmacological activities, and it is used as an active ingredient of drugs such as cough and expectorant, anti-inflammatory, liver protection, anti-ulcer, anti-arrhythmia, analgesic, sedative, hypnotic, and immune-enhancing drugs. There is no literature report on the application of petrin in agriculture, especially as an insecticidal pesticide

Embodiment 1

[0020] Example 1: Toxicity assay

[0021] Sample: Aureridin, Scopoletin, Escin, Osthole, Escin, Oxyprescurin, Imimperatorin, Isoimperatorin, Psoralen, Isopsoralen, Xanthotoxin, bergamotide, isobergamotide, anisolide, isoanisinolide, astragalus, and petrin, a total of 17 compounds were screened for toxicity, and the purity of the sample was above 98%.

[0022] 1.1 Determination of contact activity and toxicity to female adults and larvae of Panonychus citrus:

[0023] The above 17 compounds were dissolved in acetone to make a mother solution of 100g / mL, and the compounds were diluted to 1000, 2000, 4000, 8000, 16000, 32000, 64000 times respectively for evaluation of acaricidal activity, and pyridaben EC was used as a control .

[0024] Determination by glass slide dipping method: under a dissecting microscope, paste the female adult mites and young mites with their feet facing the sky and their backs facing down on a glass slide with double-sided adhesive tape, 40 heads per p...

Embodiment 2

[0028] Recipe: 0.5kg of petrin, 4kg of soybean oil, 2kg of lecithin, and 90kg of water.

[0029] Add petrin and lecithin into soybean oil, heat and stir at 30-40°C until completely dissolved; cool to room temperature, add 10kg of water, and stir until the foam is eliminated; add the rest of the water, and continue to stir to obtain an oil-in-water emulsion .

Embodiment 3

[0031] Recipe: 0.7kg of petrin, 5kg of soybean oil, 3kg of lecithin, 90kg of water, 2kg of methanol, 1kg of sodium lauryl sulfate, 1kg of penetrant T, and 1kg of carbomer.

[0032] Mix petrin and methanol and add to soybean oil, add lecithin, heat and stir at 30-40°C until completely dissolved; cool to room temperature, add sodium lauryl sulfate, penetrant T, carbomer and continue to stir and mix Evenly; add 10kg of water, stir until the foam is eliminated; add the rest of the water, continue to stir evenly to obtain an oil-in-water emulsion.

Abstract

The invention discloses a botanical pesticide for killing pests and a preparation method of the pesticide. The pesticide comprises components in parts by weight as follows: 0.3-0.8 parts of bergenin, 3-5 parts of an oil-phase solvent, 1-3 parts of an emulsifier and 10-90 parts of water. The bergenin is added to the oil-phase solvent, the emulsifier is added, and the mixture is heated and stirred until being completely dissolved; the mixture is cooled to the room temperature; a proper amount of water is added, and the mixture is evenly stirred; the rest water is added, the mixture is stirred continuously and evenly, and the botanical pesticide for killing the pests is obtained. The botanical pesticide is highly sensitive to Panonychus citri, has the very high acaricidal activity and is ecological, environment-friendly, free of pollution and accumulation and suitable for agricultural popularization, and materials are easy to take.

Description

technical field [0001] The invention relates to an insecticidal pesticide, in particular to a botanical pesticide used for insecticidal. Background technique [0002] Citrus is the world's largest fruit industry and the third largest agricultural product in international trade. It is cultivated in 138 countries and regions around the world, and its planting area exceeds 8 million hectares 2 , with an annual output of more than 120 million tons. At present, the major citrus producing countries are Brazil (23.7%), the United States (15.9%), China (10.8%), Mexico (5.5%) and Spain (3.6%), and the output of these countries together accounts for 60.5% of the world. my country is the country with the largest citrus production, and the Yunnan-Guizhou Plateau is considered to be the origin of citrus. In 2003, the area and output of citrus in my country were 1.5057 million hm 2 and 13.35 million tons, which has increased to 2.0308 million hm by 2008 2 and 23.31 million tons, an i...
