Bactericide for preventing peach tree gummosis disease, and preparation method thereof

Abstract

The invention belongs to the field of an agricultural technology, and particularly relates to a bactericide for preventing the peach tree gummosis disease, and a preparation method thereof. The bactericide for preventing the peach tree gummosis disease is prepared from the following raw materials: uncinata spikemoss herb, onion, sweet-scented osmanthus, radix peucedani, radix scutellariae, herba houttuyniae, herba taraxaci, green algae, sweet wormwood herb, arabidopsis thaliana, tobacco, garlic flakes, anchusa azurea, Chinese weeping cypress leaf, phytic acid and methylcellulose. The raw materials are extracted by adopting different methods, the effective components in the raw materials can be fully utilized, and the prepared bactericide has a good prevention effect on the peach tree gummosis disease, and is fast to take effect and low in recurrence rate.

Description

technical field [0001] The invention belongs to the technical field of agriculture, in particular to a fungicide for preventing and treating peach tree gummosis and a preparation method thereof. Background technique [0002] Peach is a plant belonging to the genus Peach in the family Rosaceae. Its fruit is delicious, clear and sweet. Peach meat is rich in protein, fat, carbohydrates, crude fiber, calcium, iron, carotene, vitamin B, citric acid, glucose and other nutrients, and has a good therapeutic effect on patients with hypokalemia and iron deficiency anemia. Peach tree gummosis is one of the important diseases of peach trees. It mainly harms the branches of peach trees. The bark of the affected branches is rough and cracked, which is not easy to heal, and yellow-brown transparent jelly flows out, causing the tree to weaken and reduce production. or dead trees. [0003] The main reasons for peach tree gummosis: 1. The harm of parasitic fungi and bacteria, such as dry ro...

Problems solved by technology

[0003] The main reasons for peach tree gummosis: 1. The harm of parasitic fungi and bacteria, such as dry rot, rot, anthracnose, bacterial perforation, fungal perforation, etc. These diseases or parasitic branches, or crisis leaves , so that the growth of peach trees is weakened and the resistance is reduced; 2. Insect damage, especially dry borer pests, can easily induce gum flow in wounds caused by pests; 3. Wounds caused by mechanical damage, freezing damage, sun burns, etc.; 4. Bad scion and Use incompatible rootstocks; 5. Poor drainage and improper irrigation

At present, the agents used in the prevention and treatment of gummosis are basically chemical pesticides and fungicides. The extensive use of chemical pesticides will easily cause environmental pollution, and at the same time, it will also cause drug resistance and stress resistance of plant pathogenic bacteria, which increases the difficulty of prevention and control; Therefore, many scholars have conducted research on "pollution-free" pesticides, but these new fungicides still have poor pest control ability, slow wound healing, and their efficacy is easily affected by the natural environment.

Such as the patent application number is 201310216298.5, which discloses a natural fungicide for preventing and treating peach tree gummosis and its preparation method. The fungicide made from raw materials such as bitter melon, reed, ivy, and alfalfa has a great effect on the prevention and treatment of bacteria and fungi. Good effect, but basically has no effect on pest control. At the same time, this fungicide basically has no promoting effect on the healing of peach tree branch cracks and wounds, making the healing of cracks and wounds slow, and easily causing the recurrence of gummosis; For example, the natural fungicide, preparation method and application method disclosed in the document with the patent application number 201711155030.X for the prevention and treatment of peach tree gummosis, the fungicide made from raw materials such as wormwood, lovage, smilax, Morinda officinalis, The ability to prevent and control bacteria and fungi is strong, but the ability to promote crack and wound healing and prevent and control insect pests is poor, and the active ingredients in the fungicide will oxidize and decompose in the natural environment, which will reduce the efficacy of the fungicide
