Embodiment 1

[0029] The present embodiment provides a kind of insecticide, and raw material component comprises:

[0030] 30 parts by weight of gourd leaves, 5 parts by weight of leaves of apricot tree, 15 parts by weight of fennel grass, and 5 parts by weight of garlic roots.

[0031] Further, a method for preparing the insecticide is provided, comprising the steps of:

[0032] (1) gourd leaves, apricot leaves, pompon grass, and garlic roots must be washed respectively, squeezed out after adding 2 times of quality water, and filtered for the first time to obtain each raw material filtrate with a solid particle size of about 90 μm. The raw material filtrate was homogenized at a speed of 2000rpm for 5 minutes, and then filtered for the second time to obtain gourd leaf juice, apricot leaf juice, pompon grass juice, and garlic root whisker juice with a solid particle size of about 18 μm;

[0033] (2) After mixing the cucurbit leaf juice, apricot leaf juice and pomegranate juice described in ...

Embodiment 2

[0037] The present embodiment provides a kind of insecticide, and raw material component comprises:

[0038] 50 parts by weight of cucurbit leaves, 15 parts by weight of apricot leaves, 25 parts by weight of fennel grass, and 15 parts by weight of garlic roots.

[0039] Further, a method for preparing the insecticide is provided, comprising the steps of:

[0040] (1) gourd leaves, apricot leaves, fluffy grass, and garlic roots must be washed respectively, squeezed out after adding 6 times of quality water, and filtered for the first time to obtain each raw material filtrate with a solid particle size of about 96 μm. The raw material filtrate was first homogenized at a speed of 3000rpm for 15 minutes, and then filtered for the second time to obtain gourd leaf juice, apricot leaf juice, fluffy grass juice, and garlic root whisker juice with a solid particle size of about 10 μm;

[0041] (2) After mixing the cucurbit leaf juice, apricot leaf juice and pomegranate juice described...

Embodiment 3

[0045] The present embodiment provides a kind of insecticide, and raw material component comprises:

[0046] 35 parts by weight of gourd leaves, 8 parts by weight of leaves of apricot tree, 17 parts by weight of pompon grass, and 8 parts by weight of garlic roots.

[0047] Further, a method for preparing the insecticide is provided, comprising the steps of:

[0048] (1) gourd leaves, apricot leaves, pompon grass, and garlic roots must be washed respectively, squeezed out after adding 4 times of quality water, and filtered for the first time to obtain each raw material filtrate with a solid particle size of about 90 μm. The raw material filtrate was first homogenized at a speed of 2500rpm for 10 minutes, and then filtered for the second time to obtain gourd leaf juice, apricot leaf juice, fluffy grass juice, and garlic root whisker juice with a solid particle size of about 16 μm;

Abstract

The invention relates to a pesticide and a preparation method thereof. According to the pesticide, cucurbit leaves, apricot leaves, halogeton arachnoideus and garlic root hairs are adopted as raw materials and subjected to proper weight ratio, thus the pest-killing functional components of all the raw materials interact and are synergistically enhanced, the pesticide has the significant killing effect on crop pests and has the broad-spectrum effect. According to the preparation method of the pesticide, by optimizing the preparation process, the extracting efficiency is significantly improved,and active components are better reserved. In addition, the pesticide is extracted from natural plants, environmental protection is achieved, the toxic and side effects on the human body are avoided,using is safer, and the preparation method is simple, the cost is low, and the pesticide is suitable for industrial production.
