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

[0032] Example 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;

Embodiment 2

[0036] Example 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;

Embodiment 3

[0040] Example 4

[0041] (1) Crush 4 kg of dried jicama stems and leaves and 0.5 kg of ranunculus into 50-mesh powder, put them into an extraction tank, inject 27 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;

[0042] (2) Pour the extracted jicama stems and leaves and the filter residue of ranunculus into 22.5 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;

Abstract

The invention relates to the technical field of agricultural insecticides and particularly relates to a plant source biological composition. The plant source biological composition contains alcohol extracts of pachyrrhyizus erosus stems and leaves and herba ranunculi japonici, and abamectin medicine residues. The invention provides application of the plant source biological composition to prevention and treatment of green onion maggots. After screening tests for many years, a granule plant source pesticide, which is prepared by adding the alcohol extracting liquid of the pachyrrhyizus erosus stems and leaves and herba ranunculi japonicai into the abamectin medicine residues, has an obvious effect on preventing and treating the green onion maggots and lasts for a long period; in a whole growth season of green onions, a chemical pesticide does not need to be used for preventing and treating; the plant source biological composition has the effect of a fertilizer and has no pollution and no residues; and the raw materials are very cheap and are easily available so that the market prospect is wide.

Description

technical field [0001] The present invention relates to the technical field of agricultural pesticides, in particular to a plant-derived biological composition, a preparation method of the plant-derived biological composition, and an application of the plant-derived biological composition in preventing and treating onion maggots. Background technique [0002] onion( Allium fistulosum ) is a commonly used condiment in cooking. It has the functions of increasing fragrance, removing mutton, and removing fishy smell. It is also a traditional Chinese medicine. Important position. However, in recent years, with onion maggots ( Delia antigua (Meigen) ) damage is increasing day by day, onion stems are bored into holes, causing rot, leaves withered and yellow, wilting and even dead seedlings. The damage rate in general years is 25%-35%, and it can reach more than 50% in severe cases. In order to reduce the damage caused by scallion maggots and ensure that the output of scallio...
