Problems solved by technology

However, due to the low insecticidal specificity of chemical pesticides, the residual effect period in the field is long, and it is easy to induce pests to develop resistance to them, especially the pollution of agricultural products and the environment caused by residual chemical pesticides, resulting in miscarriage of women, baby deformities and induced human Various cancers and other diseases, so the use of biopesticides to control pests is increasingly valued by humans

Embodiment 1

[0016] The insecticide for mango tree saplings comprises the following components and parts by weight: 10 parts of Vitex japonica seeds, 10 parts of neem seeds, 2 parts of synergist, 3 parts of saplings, 3 parts of planeweed, and 5 parts of scopolamine. The synergist is 50% ramie oil and 50% Span-20.

[0017] The extraction method of ramie oil is as follows: cut and crush the collected fresh ramie plants, pass through a 50-mesh sieve, take ramie plant powder, add 5 times the volume of acetone, stir and extract for 7 hours, centrifuge and concentrate under reduced pressure to obtain ramie oil .

[0018] The preparation method of mango tree sapling insecticide comprises the following steps:

[0019] 1) Pretreatment: pre-soak the neem seeds / Vitex argentina seeds and then perform steam explosion, the pressure is controlled at 3.5MPa, and the maintenance time is 50s to obtain the explosive neem seeds / Vitex vitex seeds; adding petroleum ether for extraction , layering and taking t...

Embodiment 2

[0025] The insecticide for mango tree saplings has the following components and parts by weight: 8 parts of Vitex japonica seeds, 12 parts of neem seeds, 2 parts of synergist, 2 parts of saplings, 3 parts of planeweed, and 6 parts of scopolamine. The synergist is 50% ramie oil and 50% Span-20 and Tween-80.

[0026] The extraction method of ramie oil is as follows: cut and crush the collected fresh ramie plants, pass through a 50-mesh sieve, take ramie plant powder, add 5 times the volume of acetone, stir and extract for 7 hours, centrifuge and concentrate under reduced pressure to obtain ramie oil .

[0027] The preparation method of mango tree sapling insecticide comprises the following steps:

[0028] 1) Pretreatment: pre-soak the neem seeds / Vitex argentina seeds and then perform steam explosion, the pressure is controlled at 3.5MPa, and the maintenance time is 50s to obtain the explosive neem seeds / Vitex vitex seeds; adding petroleum ether for extraction , layering and ta...

Embodiment 3

[0034] The insecticide for mango tree saplings comprises the following components and parts by weight: 5 parts of Vitex japonica seeds, 10 parts of neem seeds, 2 parts of synergist, 3 parts of saplings, 3 parts of planeweed, and 6 parts of scopolamine. The synergist is 40% ramie oil and 60% Tween-80.

[0035]The extraction method of ramie oil is as follows: cut and crush the collected fresh ramie plants, pass through a 50-mesh sieve, take ramie plant powder, add 5 times the volume of acetone, stir and extract for 7 hours, centrifuge and concentrate under reduced pressure to obtain ramie oil .

[0036] The preparation method of mango tree sapling insecticide, optimization steps:

[0037] 1) Pretreatment: Pre-soak neem seeds / Vitex argentina seeds and then steam explosion, the pressure is controlled at 3.5MPa, and the maintenance time is 50s to obtain neem seed explosives / Vitex vitex seeds explosives; add petroleum ether solution Extraction, layering and taking the upper phase ...

Abstract

The invention discloses a preparation method for a mango sapling insecticide. The insecticide comprises the following components in parts by weight: 5-10 parts of vitex negundo seeds, 8-15 parts of azadirachta indica seeds, 1-3 parts of a synergist, 1-3 parts of stemona roots, 1-3 parts of fragrant eupatorium herb, and 3-6 parts of scopola, wherein the synergist comprises 40-60% of boehmeria niveaoil and 40-60% of one or more selected from Span and Tween. The insecticide provided by the invention has the beneficial effects that the components in the insecticide have obvious mutual coordination effects, can directly act on fat bodies and midgut cell nucleuses of insect larvae, can quickly reproduce to lead to disease infection and death of the larvae, can cause epidemics in populations through horizontal infection, can kill pupas and eggs through vertical infection, and can effectively control pest populations and damage of the pest populations. The insecticide provided by the invention has a rapid pest killing speed, and only needs half a day to one day from spraying of the insecticide to starting of dead pests.

Description

technical field [0001] The invention relates to the field of insecticides, in particular to a preparation method of an insecticide for mango tree saplings. Background technique [0002] With the development of modern science and technology, chemical pesticides are widely used because of their advantages such as wide adaptability, simple operation, low cost and remarkable effect. However, due to the low insecticidal specificity of chemical pesticides, the residual effect period in the field is long, and at the same time, it is easy to induce pests to develop resistance to them, especially the pollution of agricultural products and the environment caused by residual chemical pesticides, resulting in miscarriage of women, baby deformities and induced human Various cancers and other diseases, so the use of biopesticides to control pests is increasingly valued by humans. Biological pesticides mainly include microbial-derived pesticides, botanical-derived pesticides, and animal-d...
