Problems solved by technology

[0004]In order to solve the problem of agricultural production in the prevention and control of onion maggots, there are no good biological pesticides, so excessive use of chemical pesticides, and even illegal use of highly toxic pesticides banned by the country, resulting in pesticides The residue exceeds the standard seriously, which poses a huge threat to the health and safety of humans and animals. At present, there are very few biopesticides on the market to control onion maggots, the effect is not good, the price is high, and almost no one uses them.

Embodiment 1

[0029] (1) Grind 2.5 kg of dried jicama stems and leaves and 0.5 kg of ranunculus into 50-mesh powder, put them into an extraction tank, inject 18 kg of 50% ethanol solution, stir well, and keep the temperature of the extract at about 60°C Extract for 1.5 hours with constant stirring during extraction. After the extraction is completed, filter, the filtrate is set aside, and the filter residue is extracted again;

[0030] (2) Pour the extracted jicama stems and leaves and the filter residue of ranunculus into 15 kg of 60% ethanol solution, keep the temperature of the extract at 60°C for 30 minutes, and keep stirring during the extraction. After the extraction is completed, filter again, retain the filtrate, and discard the filter residue;

[0031] (3) Combine the weight of the filtrate from the above two extractions to 23.1 kg, add 0.023 kg of potassium dihydrogen phosphate (stabilizer) and 2.3 g of ascorbyl palmitate (antioxidant), stir and mix, and then add 30 kg of a Add ...

Embodiment 2

[0033] (1) Crush 3 kg of dried jicama stems and leaves and 0.5 kg of ranunculus into 50-mesh powder, put them into an extraction tank, inject 21 kg of 50% ethanol solution, stir well, and keep the temperature of the extract at about 60°C Extract for 1.5 hours with constant stirring during extraction. After the extraction is completed, filter, the filtrate is set aside, and the filter residue is extracted again;

[0034] (2) Pour the extracted jicama stems and leaves and the filter residue of ranunculus into 17.5 kg of 60% ethanol solution, keep the temperature of the extract at 60°C for 30 minutes, and keep stirring during the extraction. After the extraction is completed, filter again, retain the filtrate, and discard the filter residue;

[0035] (3) Combine the weight of the filtrate from the above two extractions to 26.7 kg, add 0.027 kg of potassium dihydrogen phosphate (stabilizer) and 2.67 g of ascorbyl palmitate (antioxidant), stir and mix, and then add 40 kg of a Add...

Embodiment 3

[0037] (1) Crush 2 kg of dried jicama stems and leaves and 0.5 kg of ranunculus into 50-mesh powder, put them into an extraction tank, inject 15 kg of 50% ethanol solution, stir well, and keep the temperature of the extract at about 60°C Extract for 1.5 hours with constant stirring during extraction. After the extraction is completed, filter, the filtrate is set aside, and the filter residue is extracted again;

[0038] (2) Pour the extracted jicama stems and leaves and the filter residue of ranunculus into 12.5 kg of 60% ethanol solution, keep the temperature of the extract at 60°C for 30 minutes, and keep stirring during the extraction. After the extraction is completed, filter again, retain the filtrate, and discard the filter residue;

[0039] (3) Combine the weight of the filtrate from the above two extractions to 19 kg, add 0.019 kg of potassium dihydrogen phosphate (stabilizer) and 1.9 g of ascorbyl palmitate (antioxidant), stir and mix, and then add 20 kg of Add 1.9 ...

Abstract

The invention relates to the technical field of agricultural insecticides, in particular to a plant-derived biological composition, which contains alcohol extracts of potato stems and leaves, buttercups, and abamectin dregs. Application of plant-derived biological composition in the prevention and treatment of onion maggots. After many years of screening tests, the present invention finds that the botanical pesticides made of yam bean stems and leaves and ranunculus alcohol extracts and abamectin dregs to make granules have obvious effects on preventing and treating scallion maggots, and have a long lasting effect. There is no need to use chemical pesticides to prevent and control the whole growing season, and it has the effect of fertilizer, no pollution, no residue, the raw materials are very cheap and easy to get, and the market prospect is broad.

Description

Technical field [0001] The present invention involves the field of agricultural pesticides, which specializes in a plant source biological composition, also involves the preparation method of plant source biomedical compositions, and also involves the application of plant source biological compositions in the prevention and treatment of onion maggots. Background technique [0002] onion( Alliumfistulosum ) It is a commonly used seasoning in cooking. It has the functions of adding fragrance, removing 膻, and removing fishy. It is also a traditional Chinese medicine. It can sweat and solve the meter, scattered cold and yang, detoxify and disperse, prevent and treat epidemic diseases.Important position.However, in recent years, with the onion maggots ( Deliaantigua (Meigen) ) The harm is increasing, the green onion stems are touched, causing rot, the leaves are yellow, the withered and even the seedlings are made, and the general year's victims are 25%-35%, which can reach more than ...
