Composite chemical for preventing and treating bark rot of tree

Abstract

A combined medicament for preventing and treating tree rot, comprising medicament A directly applied to the affected part of the plant (its composition and weight ratio are: 15-25% capillary, 20-25% platycodon, 50- 65%, each component is put into the frying pan, adds appropriate amount of water, boils to 1 / 3rd of the added water, gets final product) and the medicament B (its composition and weight percent distribution ratio of being buried in the soil around the tree root) : Mint 5-15%, Stachys 0-10%, Artemisia 5-25%, Licorice 5-25%, Fangfeng 0-10%, Chrysanthemum 5-20%, Capillary 10-35%, Diding 0- 20%, Platycodon grandiflorum 3-25%, each component is pulverized separately, fried, and then mixed to obtain). The invention adopts pure natural formula, is non-toxic, has no pollution to the environment, does not produce pesticide enrichment phenomenon, can completely cure tree rot, and also has the effects of improving the ability of plants to prevent diseases and insect pests and comprehensively improving plant immunity.

Description

Technical field: [0001] The present invention relates to a combination of medicaments for preventing and treating tree rot, in particular to a combination of two medicaments that are directly sprayed on the diseased part of the tree and buried in the soil around the roots of the tree to treat the rot of the tree. comprehensive medicine. Background technique: [0002] In recent years, due to changes in climatic conditions and ecological environment, a large area of ​​rotten skin disease (scientific name: dirty black rotten skin) broke out in willows, poplars, and fruit trees in the Northeast. Rarely, under normal circumstances, the bacteria that cause skin rot are weak parasitic bacteria, which can only infect plants with poor growth and weak tree vigor, and are not easy to cause complete death of plants, but the plants lack good maintenance for a long time or due to Changes in objective conditions such as climate, soil, hydrology, and air pollution exceed a certain critical...

[0002] In recent years, due to changes in climatic conditions and ecological environment, a large area of ​​rotten skin disease (scientific name: dirty black rotten skin) broke out in willows, poplars, and fruit trees in the Northeast. Rarely, under normal circumstances, the bacteria that cause skin rot are weak parasitic bacteria, which can only infect plants with poor growth and weak tree vigor, and are not easy to cause complete death of plants, but the plants lack good maintenance for a long time or due to Changes in objective conditions such as climate, soil, hydrology, and air pollution exceed a certain critical value, leading to the disorder of the tree's immune system itself, which can induce abnormal outbreaks of various diseases. According to traditional techniques such as Chinese garden plant protection (Xia Baochi, Shen Baiyan) Edited, Jiangsu Science and Technology Publishing House, August 1992, pages 485-486) ​​pointed out in the book that the method of preventing and treating poplar (willow, pagoda tree) rotten skin disease, in addition to selecting disease-resistant varieties, improving disease resistance and preventive ability In addition to non-active methods such as non-active methods, the main treatment drugs are body surface agents such as Bordeaux serum, chlorothalonil, carbendazim, thiram, thiophanate-methyl mercury, tuzet, etc. The long-term use of these drugs makes the drug effect gradually It tends to become smaller, and causes the killing of natural enemies, causing pests to develop resistance, and causing diseases to become more rampant. New types of diseases continue to appear, and various types of plant diseases and insect pests are facing more and more frequent and serious outbreaks. Negative effects such as diseases and insect pests are still hard to prevent
