Problems solved by technology

Chemical pesticide control is a method with a high rate of use in the control of walnut rot disease. Common fungicides are usually used in combination with corresponding antibiotics for comprehensive control. Commonly used are octoprobin, agricultural streptomycin, thiophanate-methyl, and high-concentration caustic soda However, after the use of chemical pesticides, traces of pesticide original bodies and toxic metabolites remaining in organisms, agricultural by-products, and the environment pollute the environment; physical methods of prevention and control are mainly through pruning and scraping the diseased spots, and completely scraping the diseased spots This method of prevention and treatment will damage the phloem and xylem of the trunk, affect the nutrient transport of the tree, and may further reduce the tree vigor and cause secondary infection of rot pathogens. This method is suitable for small diseased spots, young tree age, and relatively vigorous tree vigor The use of walnut trees at the early fruit stage is not suitable for the full fruit stage and old and weak trees; biological control uses the antagonism between microorganisms to achieve comprehensive control of pathogenic bacteria, but the cost is relatively high

Embodiment 1

[0023] Embodiment one: for preparing the medicament for preventing and treating walnut rot

[0024] The invention provides a medicament for preventing and treating walnut rot, which comprises 35-45 parts of wood tar, 15-30 parts of wood vinegar, 8-14 parts of total alkaloids of Sophora sophora, and isoflavones according to the ratio of parts by weight. 2-8 parts of lignans, 4-10 parts of astragalus, and 10-20 parts of surfactants.

Embodiment 2

[0025] Embodiment two: be used for the application of preparation control walnut rot disease medicament

[0026] The present invention specifically provides an application for preparing a medicament for preventing and treating walnut rot, and the application method is as follows through the following specific steps:

[0027] (1) Every spring, walnuts begin to germinate and autumn walnuts are harvested to carry out preventive treatment. Saw off the branches of walnut rot disease, scrape off the rotten spots on the tree body, expose the xylem, apply control agents on the diseased parts, and wrap the above-mentioned walnuts with straw curtains. Provided for the preparation of medicaments for the prevention and treatment of walnut rot disease, wrapping the smeared part;

[0028] (2) Spray the diluted preventive agent on walnut orchards suffering from rot, once every 3 days, and spray 2-4 times in total.

[0029] According to the present invention, the walnut rot diseased branches...

Embodiment 3

[0032] Embodiment three: for preparing the medicament for preventing and treating walnut rot

[0033] Every spring, the walnuts start to germinate and after the walnuts are harvested in autumn, preventive treatment is carried out. Saw off the affected branches of walnut rot, and scrape off the diseased spots on the trunk together with the phloem tissue at a radius of 2-3 cm around the diseased spots to expose the xylem , apply the control agent on the diseased part, and wrap the control agent with straw curtains, and wrap the smeared area; spray 40 times the dilution of the control agent in the walnut orchard, spray once every 3 days, and spray twice in total; the control agent for walnut rot disease, Including 3.5kg of wood tar, 1.5kg of wood vinegar, 1.4kg of total alkaloids of Sophora alopecuroides, 0.8kg of isoflavone lignans, 0.8kg of astragalus, and 1.5kg of surfactants.

Abstract

The invention discloses a medicament for preparing and preventing walnut rot and its application. By selecting 35-45 parts of wood tar, 15-30 parts of wood vinegar, 8-14 parts of total alkaloids of Sophora sophora, 2-8 parts of isoflavone lignans, 4-10 parts of astragalus, and 10-20 parts of surfactants Combining with the physical method of sawing off diseased branches, scraping off diseased spots, and spraying walnut orchards with diluents, the amount of pesticides used can be greatly reduced. No chemical pesticides are added to the control agents, no pollution, and low cost. Low, and the wound surface of physical control treatment is small, and the agent can penetrate deep into the xylem, so that the internal and external pathogens can fully contact with the agent, which is conducive to the exertion of the drug effect, and has a significant effect on the prevention and treatment of walnut rot disease, which has the value of popularization and application.

Description

technical field [0001] The invention relates to the field of prevention and control of fruit tree diseases and insect pests, in particular to the technical field of preparing a medicament for preventing and treating walnut rot and its application. Background technique [0002] Walnut (Juglans regia L.) is an important woody oil tree species with high economic, ecological and social benefits. In recent years, with the country's strong support for the woody oil industry, the market demand has gradually increased, and the cultivation area of ​​walnut has continued to expand. Walnut rot is a kind of branch disease caused by pathogenic fungi. The pathogenic fungi overwinter in the diseased part as mycelium or pycnidia, and produce conidia in the next year, which are spread by wind, rain and insects. Spring and autumn It is the peak period of the disease, when the air humidity is high, a large number of conidia are produced, and multiple infestation hazards are carried out. The di...
