Problems solved by technology

However, the frequency of use of most pesticides is relatively high, and the use of highly toxic and high-residue pesticides is still common, which seriously endangers the environment and people's health; unreasonable use of chemical pesticides for a long time to prevent and control watermelon wilt, causing pathogenic bacteria to gradually develop drug resistance. The effect is reduced, and it will increase the pesticide residues in the fruit, pollute the environment, and increase the production cost

Embodiment 1

[0020] A plant source fungicide preparation, which comprises the following components in percentage by weight: Thymol 2%, emulsifier (the emulsifier is phenylethylphenol polyoxyethylene polyoxypropylene ether) 20%, azone 3%, ethanol 40% %, water 35%, and the plant-derived fungicide preparation contains Trichoderma 1×10 8 pieces / ml.

[0021] The preparation method of the above-mentioned plant-derived bactericidal preparation, prepare raw materials thymol, emulsifier, azone, ethanol and water according to the formula amount, add thymol to 1 / 4 amount of ethanol and mix uniformly to form solution A, and then emulsifier Dissolve azone and azone with the remaining 3 / 4 amount of ethanol to form solution B, then mix solution A, solution B and water evenly, add Trichoderma to the solution until the amount of bacteria reaches 1×10 8 pieces / ml.

Embodiment 2

[0023] A plant source fungicide preparation, which comprises the following components in percentage by weight: thymol 1%, emulsifier (emulsifier is calcium dialkylbenzenesulfonate) 10%, azone 2%, ethanol 30%, water 57% %, and, the plant source fungicide contains Trichoderma 1 × 10 8 pieces / ml.

[0024] The preparation method of the above-mentioned plant-derived bactericidal preparation, prepare raw materials thymol, emulsifier, azone, ethanol and water according to the formula quantity, add thymol to 1 / 2 amount of ethanol and mix uniformly to form solution A, and then emulsifier Dissolve Azone with the remaining 1 / 2 amount of ethanol to form solution B, then mix solution A, solution B and water evenly, add Trichoderma to the solution until the amount of bacteria reaches 1×10 8 pieces / ml.

Embodiment 3

[0026] A kind of plant source bactericidal preparation, it comprises the component of following percentage by weight: Thymol 0.5%, emulsifying agent (emulsifying agent is phenylethylphenol polyoxyethylene ether and alkylphenol polyoxyethylene ether phosphate by weight ratio 1 : 2 mixture) 10%, azone 2%, ethanol 20%, water 67.5%, and, described plant source bactericidal preparation contains Trichoderma 1 * 10 9 pieces / ml.

[0027] The preparation method is the same as in Example 2.

Abstract

The invention discloses a botanical bactericidal preparation. The botanical bactericidal preparation comprises the following components, by weight, 0.1-50% of thymol, 5-30% of an emulsifier, 0.1-20% of azone, 10-60% of ethanol, and 0.1-84.8% of water, and 1ml of the botanical bactericidal preparation comprises Trichoderma spp with the number of 1*10<7-9>. The invention also discloses a preparation method of the botanical bactericidal preparation and an application of the botanical bactericidal preparation in the blight control. The thymol-based botanical bactericidal preparation of the invention, which has effective components from plants with the insecticidal function or extracts from the plants, allows the blight of crops to be effectively controlled, and has the multiple efficacies of crop growth promotion, yield and income increase, quality improvement, nutrient utilization rate improvement, pest control, no pollution, and the like, is suitable for the production of nuisance-free,green and organic agricultural products.

Description

technical field [0001] The invention belongs to the technical field of disease prevention and treatment of fruits and vegetables in agricultural production, and in particular relates to a botanical bactericidal preparation and its application in the prevention and treatment of Fusarium wilt. Background technique [0002] Watermelon Fusarium wilt, also known as watermelon vine cutting disease, wilt disease, and wilt disease, is a worldwide soil-borne disease caused by Fusarium oxysporum f.sp.niveum. One of the main diseases of watermelon is known as "watermelon cancer". Especially in recent years, it has occurred in various watermelon producing areas in my country. With the expansion of watermelon planting area, combined with single planting mode, unreasonable crop rotation, and continuous cropping obstacles, the damage of watermelon wilt is increasing year by year. , watermelon wilt has become the main disease in watermelon production. Fusarium wilt of watermelon is a soi...
