Embodiment 1

[0032] A bactericide consisting of the following parts by weight of raw materials: 5 parts of Solidago canadensis volatile oil, 11 parts of Jinggangmycin, 3 parts of scallions, 30 parts of licorice, 3 parts of purslane, 10 parts of Chinese pepper, difentriconazole 2 parts, 41 parts of solvent, 11 parts of co-solvent and 12 parts of antifreeze.

[0033] The present invention also provides a preparation method of the above-mentioned bactericide, which consists of the following steps:

[0034] (1) Collect green onions, licorice, purslane, and Chinese pepper from the middle of the plants, and then pulverize them with a plant grinder to a 4mm coarse crushed product, soak the coarse crushed product in 85% ethanol for 3 months, and extract the supernatant Standby, that is, the plant source extract of the fungicide;

[0035] (2) Distillation and separation: Put Solidago canadensis in a distillation pot, add water to the pot soak the Solidago canadensis, heat the bottom of the pot, and intro...

Embodiment 2

[0039] A bactericide consisting of the following parts by weight of raw materials: 10 parts of Solidago canadensis volatile oil, 6 parts of Jinggangmycin, 5 parts of scallions, 15 parts of licorice, 14 parts of purslane, 2 parts of Chinese pepper, difentriconazole 7 parts, 25 parts of solvent, 16 parts of co-solvent and 2 parts of antifreeze.

[0040] The preparation method is the same as in Example 1.

Embodiment 3

[0042] A bactericide, consisting of the following parts by weight of raw materials: 6 parts of Solidago canadensis volatile oil, 11 parts of Jinggangmycin, 3 parts of shallots, 30 parts of licorice, 3 parts of purslane, 10 parts of Chinese pepper, and difentriconazole 2 parts, 41 parts of solvent, 11 parts of co-solvent and 12 parts of antifreeze.

[0043] The present invention also provides a preparation method of the above-mentioned bactericide, which consists of the following steps:

[0044] (1) Collect green onions, licorice, purslane, and Chinese pepper from the middle of the plants, and then pulverize them with a plant grinder to a 6mm coarse crushed product, soak the coarse crushed product in 80% ethanol for 3 months, and extract the supernatant Standby, that is, the plant source extract of the fungicide;

[0045] (2) Distillation and separation: Put Solidago canadensis in a distillation pot, add water to the pot soak the Solidago canadensis, heat the bottom of the pot, and i...

Abstract

The invention relates to the technical field of pesticides and discloses a bactericide and a preparing method thereof. The bactericide comprises, by weight, 5-10 parts of solidago canadensis volatile oil, 6-11 parts of validamycin, 3-5 parts of welsh onion, 15-30 parts of licorice, 3-14 parts of purslane, 2-10 parts of Chinese prickly ash, 2-7 parts of bitertanol, 25-41 parts of a solvent, 11-16 parts of a cosolvent and 2-12 parts of an antifreezing agent. The bactericide has advantages of low toxicity, environment protection, a wide bactericidal spectrum, a long duration period and capability of effectively delaying drug resistance and is used for crop disease control in agriculture.

Description

Technical field [0001] The invention relates to the technical field of pesticides, in particular to a fungicide and a preparation method thereof. Background technique [0002] In recent years, due to people’s unreasonable use of chemical pesticides and the inherent shortcomings of the medicament itself, such as a single bactericidal spectrum, multiple use of which are prone to drug resistance, and the toxic ingredients of the medicament, these have caused a series of pollution in the use of pesticides. Problems, such as environmental pollution, human and animal poisoning, killing natural enemies, destroying ecological balance, "3R" (Residue, Resistance, Resurgence) and other serious problems, these adverse effects have attracted widespread attention. In the pesticide market in recent years, the sales of domestic fungicides have been declining, mainly because their disease control effects are far less effective than those of foreign fungicides. However, the development of a new p...
