Embodiment Construction

[0020] Example 1

[0021] 10 parts of calcium nitrate solution, 8 parts of 25% chlorothalonil, 10 parts of 75% thiazolone wettable powder, 4 parts of polyvinyl alcohol solution, 4 parts of matrine, 6 parts of molybdate, 4 parts of Pulsatilla, 2.5% 6 parts of glutaraldehyde solution.

[0022] After mixing together, it is configured into a liquid with a mass multiple of 400-600 times for spraying. (When using Pulsatilla and 2.5% glutaraldehyde solution, use the alcohol extraction method to extract the extract, and the extract is used when mixing.) After the test, 400-600 times the mixture of Pythium (Pythium), Phytophthora, Rhizoctonia and other fungi have obvious inactivation effects, good bactericidal effects, and an effective rate of 93.1%.

[0023] Example 2

[0024] 15 parts of calcium nitrate solution, 12 parts of 25% chlorothalonil, 15 parts of 75% thiazolone wettable powder, 8 parts of polyvinyl alcohol solution, 8 parts of matrine, 10 parts of molybdate, 8 parts of Pulsatilla...

Abstract

The invention discloses a method for preparing a combination capable of preventing damping off of crops. The method includes the following steps that A, calcium nitrate liquor, 25% carbendazim, 75% thiodiazole-copper wettable powder, polyving akohol liquor, matrine, ammonium molybdate, protoanemonin and 2.5% glutaraldehyde solution are prepared; B, an extracting solution of the protoanemonin and the 2.5% glutaraldehyde solution is subjected to alcohol leaching; C, the calcium nitrate liquor, the 25% carbendazim, the 75% thiodiazole-copper wettable powder, the polyving akohol liquor, the matrine and the ammonium molybdate are compounded with the extracting solution obtained in the step B, ultraviolet sterilization is carried out after even stirring is completed, and accordingly the disease-resistant pesticide capable of treating damping-off of chili seedlings is prepared. The preparation method is simple, matching of the prepared product is also simple, using is convenient, and the effect of treating damping-off of the chili seedlings is good. By experimental testing, a 400-600 fold solution of the mixture has an obvious inactivation effect on fungi such as pythium, phytophthora and rhizoctonia, and the sterilizing effect is good.

Description

Technical field: [0001] The invention relates to a vegetable medicine, in particular to a method for preparing a composition for preventing crop damping. Background technique: [0002] Damping-off is caused by infection by Pythium fungi. Some species of Pythium spinosa and Phytophthora can also cause disease. It can affect the growth of seedlings, and cause seedling shortage or even destruction of seeds in severe cases. The stem base of Pythium and Phytophthora infested seedlings became water-stained and softened, causing them to wilt rapidly, and finally the stem base was linearly constricted. Sometimes the cotyledons have fallen down without showing symptoms, and the seedlings are mostly infected from the base of the stem (some people are infected from the middle of the stem), and they are water-stained at first, and quickly expand, shrink and shrink like a "line". It does not change color or is yellowish brown, and the disease develops rapidly. Before the cotyledons are st...
