Problems solved by technology

At present, imidacloprid chemical pesticides are mainly used to prevent and control aphids. The use of these chemical pesticides leads to pesticide residues, and makes the aphid population resistant to pesticides, making the control of aphids more difficult. Three neonicotinoid insecticides, memethoxam and clothianidin, have made a temporary ban decision

Embodiment 1

[0022] Pot Experiment of Controlling Chrysanthemum Chrysanthemum Aphid

[0023] Respectively, 50g of the branches, stems, leaves, and fruits trimmed from Chickweed were dried at 50°C and ground into powder, soaked in 2000ml of 30% methanol solution at room temperature for 3 days, filtered, the filtrate was concentrated under reduced pressure, and the solvent was recovered to obtain Extract the extract. The extract of Chickweed is obtained by drying the pruned branches, stems, leaves and fruits of Chickpea, pulverizing into powder, extracting and filtering. Formulated with 20% concentrate, 10% Tween and water to make up to 100% liquid. With the botanical biopesticide for preventing and treating the chrysanthemum chrysanthemum aphid of the present invention, the chrysanthemum chrysanthemum aphid has a therapeutic effect, respectively reaching 98% (diluted 100 times), 93% (diluted 150 times), 86.7% (diluted 200 times) and 84.8% (diluted 250 times).

Embodiment 2

[0025] Greenhouse Experiment on Controlling Chrysanthemum Chrysanthemum Aphid

[0026] Grind 100g of the naturally shedding and discarded Alpinia officinale leaves into powder after being dried at 40°C, soak in 1500ml of 50% ethanol solution at room temperature for 5 days, filter, take the filtrate and concentrate it under reduced pressure, recover the solvent to obtain the extraction extract. The alpinia officinale extract is obtained by drying the discarded leaves of the alpinia officinale, pulverizing into powder, extracting and filtering. Formulated with 30% concentrate, 15% Tween and water to make up to 100% liquid. With the botanical biopesticide for preventing and treating the chrysanthemum chrysanthemum aphid of the present invention, the chrysanthemum chrysanthemum aphid has a therapeutic effect, respectively reaching 100% (diluted 200 times), 99.3% (diluted 400 times), 90.6% (diluted 600 times) and 85.8% (diluted 800 times).

Embodiment 3

[0028] Field Experiment on Controlling Chrysanthemum Chrysanthemum Aphid

[0029] Utilize turmeric leaves in the process of producing and processing other products, dry them at 35°C, grind them into 200g of powder, soak them in 2500ml of 70% isopropanol solution at room temperature for 6 days, filter, take the filtrate and concentrate it under reduced pressure, recover the solvent to obtain the extraction extract . The turmeric extract is obtained by drying the leaves in the process of producing and processing other products, pulverizing them into powder, leaching and filtering. Formulated with 50% concentrate, 20% Tween and water to make up to 100% liquid. With the botanical biopesticide of the present invention for preventing and treating the chrysanthemum aphid, the chrysanthemum aphid has a therapeutic effect, respectively reaching 97.4% (150 times of dilution), 92.3% (250 times of dilution), 89.9% (350 times of dilution) and 84.2% (diluted 450 times).
