Embodiment Construction

[0020] Example 1

[0021] 10 parts of 25% plant ash extract, 8 parts of 22% potassium dihydrogen phosphate solution, 10 parts of 75% chlorothalonil wettable powder, 4 parts of sodium polyacrylate, 4 parts of matrine, 6 parts of 3% aluminum sulfate solution , 4 parts of ginger powder, 6 parts of tangerine peel.

[0022] After mixing together, configure it into a liquid with a mass multiple of 400-600 times for spraying. (When ginger powder and tangerine peel are used, use the alcohol extraction method to extract the extract, and use the extract when mixing.) After testing, the 400-600 times of the mixture is effective against Pythium (Pythium), Phytophthora ( Phytophthora), Rhizoctonia and other fungi have obvious inactivation effect, and the bactericidal effect is good, with an effective rate of 93.1%.

[0023] Example 2

[0024] 15 parts of 25% plant ash extract, 12 parts of 22% potassium dihydrogen phosphate solution, 15 parts of 75% chlorothalonil wettable powder, 8 part...

Abstract

The invention discloses a method for using sprout tumble preventing spray. The method includes the following steps that A, a stock solution is prepared, wherein the stock solution is composed of 25% plant ash leach liquor, 22% monopotassium phosphate liquor, 75% chlorothalonil wettable powder, sodium polyacrylate, matrine, 3% aluminum sulfate liquor, ginger powder and dried tangerine or orange peel; B, 25-50 ml of the 25% plant ash leach liquor is sprayed per mu on a seedbed with bottom water being fully soaked, then a layer of thin dry soil is sifted, seeds subjected to accelerating germination are sown, and fine soil is sifted for covering; C, when diseases come on, the stock solution is added with water to be diluted into a 400 fold solution for conducting spraying operation; D, the stock solution is added with water to be diluted into a 600 fold solution for conducting root-irrigation operation while spraying is carried out in the step C. The using method is simple, matching of the adopted products is simple, using is convenient, and the effect of treating damping-off of chili seedlings is good. By experimental testing, the 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 medicine for vegetables, in particular to a method for using a spray for preventing falling seedlings. Background technique: [0002] Damping-off is caused by Pythium fungus infection. 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. 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 middle of the stem). They are water-soaked at first, and soon expand, overflow and shrink and become thinner like "threads". It does not change color or is yellowish brown, and the disease develops rapidly. Before the cotyledon i...
