Problems solved by technology

However, there are certain restrictions on the arrangement of vegetable crops
The second is to select disease-resistant and tolerant tomato varieties or carry out grafting control, but there are few resistant resources to choose from
At present, agricultural streptomycin, copper ammonia, and phytomycin are widely used to control bacterial wilt, but because bacterial wilt is a systemic infection, once it occurs, bacterial fungicides cannot control its occurrence
Moreover, due to the frequent application of fungicides, the bacteria are highly resistant to pesticides, resulting in certain pesticide pollution, resulting in excessive pesticide residues and endangering human health.

preparation example Construction

[0013] A preparation for preventing and treating bacterial wilt of agricultural crops and a preparation method thereof, the raw materials of the preparation are composed of brassinosteroids, magnesium sulfate, ferrous sulfate, boric acid, compound amino acids, alcohol and water, and the addition of each raw material is: Add 0.8~1.5mg brassinolide, 0.6~0.8g magnesium sulfate, 0.05~0.08g ferrous sulfate, 0.04~0.08g boric acid, 0.6~0.8g compound amino acid, 0.8~1.0 The volume concentration in mL is 95% alcohol, 1-1.5 ml ethoxytrisiloxane, and the balance is water; the total amino acid content of the compound amino acid is ≥42%, the biological activity N is ≥16%, and the organic acid is ≥30%. Moisture content ≤ 3%, pH 6-7; the preparation of 1L preparation is taken as an example to illustrate a preparation for preventing and treating bacterial wilt in crops. The specific preparation steps are:

[0014] 1. Weigh 0.8-1.5 mg of brassinosteroid and dissolve it in 0.8-1.0 ml of alcohol...

Embodiment 1

[0019] The preparation for preventing and treating bacterial wilt of agricultural crops of the present invention is used to prevent and treat tomato bacterial wilt, and its specific operation steps are:

[0020] 1. Weigh 8 mg of brassinosteroid and dissolve it in 8 mL of alcohol with a volume concentration of 95%, add 10 ml of ethoxytrisiloxane, and mix the solution evenly to obtain a mixed solution for later use;

[0021] 2. Weigh 6g of magnesium sulfate, 0.5g of ferrous sulfate, 0.4g of boric acid and 6g of compound amino acids, add them to the mixed solution in step 1, mix well, then add water to 10L, mix well, and the resulting solution is for the prevention and treatment of bacterial wilt of crops The preparation is stored at room temperature for subsequent use;

[0022] 3. Spray the preparation at the stage of 2 true leaves of the tomato plants in the greenhouse, and set up a blank control group and a spraying reagent group at the same time, with 55 plants in each group...

Embodiment 2

[0031] The preparation for preventing and treating bacterial wilt of agricultural crops of the present invention is used for preventing and treating bacterial wilt of eggplant plants, and its specific operation steps are:

[0032] 1. Weigh 15 mg of brassinosteroid and dissolve it in 10 mL of alcohol with a volume concentration of 95%, add 15 ml of ethoxytrisiloxane, and mix the solution evenly to obtain a mixed solution for later use;

[0033] 2, take by weighing 8g magnesium sulfate, 8g ferrous sulfate, 0.8g boric acid, 8g compound amino acid, join the mixed solution of step 1, mix homogeneously, then add water and be settled to 10L, mix homogeneously, gained solution is the anti-crop cyanosis. Blight preparations, stored at room temperature for later use;

Abstract

The invention discloses a preparation for preventing and controlling crop bacterial wilt and a preparation method thereof. The preparation consists of the following raw materials: brassinolide, magnesium sulfate, ferrous sulfate, boric acid, compound amino acid, alcohol and water. The preparation method comprises the following steps of: dissolving the brassinolide into the alcohol; adding ethyoxyl trisiloxane; mixing uniformly to obtain a solution; mixing the obtained solution with the magnesium sulfate, ferrous sulfate, boric acid and compound amino acid; and adding water for fixing a volume to obtain the preparation for preventing and controlling crop bacterial wilt. The preparation for preventing and controlling crop bacterial wilt can be used for promoting the synthesis of reduced glutathione, increasing the activity of resistance enzymes, activating the expression of resistance genes, enhancing the resistance of crops, preventing bacterial from invading crops, effectively suppressing the growth of ralstonia solanacearum, remarkably relieving the mobidity extent of bacterial wilt, relieving the bacterial wilt of plants by over 54 percent, and fundamentally reducing economic loss caused by crop morbidity.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a preparation for preventing and treating bacterial wilt of agricultural crops and a preparation method thereof. Background technique [0002] The causative agent of bacterial wilt is R. solanacearum ( Ralstonia solanacearum ), which is one of plant bacterial diseases, mostly exists in hot, rainy and humid tropical, subtropical and temperate regions. Pseudomonas solanacearum Pseudomanas solanacearum Caused by Smith infestation. The pathogen likes high temperature, high humidity, and acidic environment, and the most suitable climate conditions for the onset of disease are temperature 30-37°C, and the optimum pH value is 6.6. The fungus has a wide range of hosts and can infect more than 50 families and hundreds of plants, including tomato, potato, tobacco, and eggplant in the family Solanaceae, peanuts and cowpeas in the leguminous family, monocotyledonous plants banana, gi...
