Problems solved by technology

[0006] Although some results have been achieved in the current research on fungicides for mango trees, most of them are limited in the use of efficacy experiments on several types of diseases, and only focus on the control effect, whether resistance to them is produced, and the use of intrusion. No further research has been done on issues such as how to mitigate the hazards inherent in organisms
For example, Chinese patent CN101921824 A is a method for detecting the resistance of mango anthracnose to benzimidazole fungicides. This invention well illustrates the resistance of mango anthracnose to benzimidazole fungicides. The use of benzimidoid fungicides for the control of mango tree diseases has given inspiration, but no solutions have been given for other diseases on mango trees such as mango powdery mildew, mango gray spot, mango scab, and mango algal spot , In addition, the patented invention only studies commonly used chemical fungicides, and does not study the resistance of more environmentally friendly botanical fungicides, but uses invasive organisms as one of the main components of fungicides to turn invasive plants from waste into treasure , comprehensive prevention and control has become one of the industry's research directions for the prevention and control of invasive organisms

Embodiment 1

[0031] A mango tree fungicide is composed of the following raw materials in parts by weight: 8 parts of laurel potato extract, 12 parts of chlorothalonil, 4 parts of purslane, 12 parts of quicklime, 2 parts of Chinese prickly ash, and 35 parts of solvent.

[0032] The present invention also provides the preparation method of above-mentioned mango tree fungicide, comprises the following steps:

[0033] (1) Preparation and extraction: Take the leaves of laurel potato, dry them in an oven at 70°C, crush them, soak them overnight in 80% ethanol with a solid-to-liquid ratio of 1:10, apply ultrasonic waves for 20 minutes, filter, and take the filter residue and add ethanol for extraction. Ultrasonic radiation, combined two filtrates, concentrated under reduced pressure into an extract for later use;

[0034] (2) Sterilization and separation: Take out the preserved extract-like filtrate obtained in step (1), add 400ml of deionized water, grind it with a colloid mill for 10 minutes, a...

Embodiment 2

[0038] A fungicide for mango trees is composed of the following raw materials in parts by weight: 18 parts of laurel potato extract, 5 parts of chlorothalonil, 9 parts of purslane, 3 parts of quicklime, 8 parts of Chinese prickly ash, and 20 parts of solvent.

[0039] Its preparation method is identical with embodiment 1.

Embodiment 3

[0041] A mango tree fungicide is composed of the following raw materials in parts by weight: 10 parts of laurel potato extract, 10 parts of chlorothalonil, 5 parts of purslane, 10 parts of quicklime, 4 parts of Chinese prickly ash, and 32 parts of solvent.

[0042] The present invention also provides the preparation method of above-mentioned mango tree fungicide, comprises the following steps:

[0043] (1) Preparation and extraction: Take the leaves of laurel potato, dry them in an oven at 70°C, crush them, soak them overnight in 80% ethanol with a solid-to-liquid ratio of 1:10, apply ultrasonic waves for 20 min, filter, and take the filter residue and add ethanol for extraction. Ultrasonic radiation, combined two filtrates, concentrated under reduced pressure into an extract for later use;

[0044] (2) Sterilization and separation: Take out the preserved extract-like filtrate obtained in step (1), add 400ml of deionized water, grind it with a colloid mill for 10 minutes, and ...

Abstract

Relating to the technical field of pesticides, the invention discloses a mango tree bactericide and a preparation method thereof. The mango tree bactericide is composed of the following raw materials by weight: 8-18 pars of a Anredera cordifolia extract, 5-12 pars of chlorothalonil, 4-9 pars of purslane, 3-12 parts of quick lime, 2-8 parts of Chinese prickly ash, and 20-35 pars of a solvent. The mango tree bactericide provided by the invention has the advantages of low toxicity, environmental protection, wide mango bacteriocidal spectrum, long duration, and effective mitigation of drug resistance, and achieves comprehensive utilization of invasive species, turns waste into treasure, and can be used for disease prevention and treatment in mango trees.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a fungicide for mango trees and a preparation method thereof. Background technique [0002] Mango is the popular name of mango (Flora of China) (Latin scientific name: Mangifera indica L.), a varnish mango native to India and one of the famous tropical fruits. Mango fruit contains sugar, protein, and crude fiber. The precursor carotene content of vitamin A is particularly high, which is rare in all fruits. Secondly, the vitamin C content is not low. Minerals, proteins, fats, sugars, etc. are also its main nutrients. It can be used to make fruit juice, jam, canned food, pickles, hot and sour pickles, mango milk powder, candied fruit, etc. Mango likes warmth and is not frost-tolerant. The optimum temperature for growth is 25-30°C, growth is slow below 20°C, leaves and inflorescences will stop growing below 10°C, and near-ripe fruits will suffer from cold damage. The annual ...
