Embodiment Construction

[0024] Example 1

[0025] 10 parts of 38% Qingku Like, 8 parts of 72.2% hymexazol, 10 parts of 75% chlorfenadin wettable powder, 4 parts of baicalin, 4 parts of matrine, 6 parts of indirubin, 4 parts of Pulsatilla Forsythia 6 parts.

[0026] After mixing together, configure it into a liquid with a mass multiple of 400-600 times for spraying. (When Pulsatilla and Hypericum perforatum are used, the extract is extracted by alcohol extraction, and the extract is used when mixing.) After testing, 400-600 times of the mixture is effective against Pythium, Phytophthora ( Phytophthora), Rhizoctonia and other fungi have obvious inactivation effect, and the bactericidal effect is good, with an effective rate of 93.1%.

[0027]

[0028] Example 2

[0029] 15 parts of 38% Qingkulike, 12 parts of 72.2% hymexazol, 15 parts of 75% chlorfenadin wettable powder, 8 parts of baicalin, 8 parts of matrine, 10 parts of indirubin, 8 parts of Pulsatilla Forsythia 10 parts.

Abstract

The invention discloses a preparation method of a medicament for resisting dampingoff. The preparation method comprises the following steps of A, preparing materials: 38% bacterial wilt pesticide, 72.2% hymexazol, 75% thiodiazole-copper wettable powder, baicalin, matrine, indirubin, Chinese pulsatilla root and hyperforin perforatum; B, lixiviating an extracting solution of Chinese pulsatilla root and hyperforin perforatum with alcohol; and C, compounding 38% bacterial wilt pesticide, 72.2% hymexazol, 75% thiodiazole-copper wettable powder, baicalin, matrine and indirubin with the extracting solution obtained in step B, uniformly stirring and then carrying out ultraviolet sterilization to prepare a disease-resistant medicament for chili seedling dampingoff. The preparation method disclosed by the invention is simple, a prepared product is simple in proportioning and convenient to use and good in effects on treatment of chili seedling damping-off. Experiment tests show that the liquid of 400-600 times of a mixture of the medicament has obvious inactivation functions on pythium, phytophthora, rhizoctonia and the like and has good sterilization effects.

Description

[0001] Technical field: [0002] The invention relates to vegetable medicines, in particular to a preparation method of medicines for anti-damping-off disease. [0003] Background technique: [0004] Damping-off disease is commonly known as "falling seedlings", "moldy roots", and "little foot plague", which is mainly caused by the infection of fungi of the genus Flagellate subphylum Pythium melons and fruits. Pythium thorns and some species of Phytophthora can also cause disease. It can affect the growth of seedlings, and in severe cases, it will cause lack of seedlings or even destroy them. Different types of fungi cause different symptoms. The stem bases of Pythium and Phytophthora infected seedlings were water-soaked and softened, causing them to wilt quickly, and finally the stem bases constricted linearly. Sometimes the cotyledons are lodging before showing symptoms, and most of the seedlings are infected from the base of the stem (some are also infected from the mi...
