Problems solved by technology

In recent years, the occurrence of the disease is on the rise. According to the survey, the average incidence rate reaches 50%, the severe cases reach 80%, and some serious plots reach 95%. develop
At present, the prevention and control of Paulownia arbuscular disease generally adopts comprehensive methods such as removing diseased branches, using tetracycline hydrochloride, and breeding improved varieties resistant to arbuscular disease.
Earlier, Chinese patent CN1056218A (application number is: 91102455.7, title of invention is: a kind of production method of Chinese medicine preparation for preventing and treating Paulownia arbuscular disease) discloses a kind of Chinese medicine preparation for preventing and treating Paulownia arbuscular disease. It is formulated from traditional Chinese medicine, and its preparation method is to process and process the medicine such as screening, slicing, drying, drying, and soaking. The effect is obvious, but its preparation method is complicated, and the control of large-scale paulownia forests is affected

Embodiment 1

[0014] Drugs for the prevention and treatment of Paulownia arbuscular disease, containing 20mg·L of antibiotics -1 , the content of methyl methanesulfonic acid is 20mg·L -1 .

[0015] The method of use is to measure the components according to the proportion, mix them evenly, and put them into a brown container. Take a certain amount of uniformly mixed medicinal liquid and inject it into the pith at the base of the Paulownia tree trunk or spray on the leaves. The pith of Paulownia is large, and two holes deep to the pith can be drilled at a 45-degree angle on one side of the diseased branch at the base of the trunk, injected after the sap flows in spring to late summer, and sprayed on the leaves during the tree growth season. The amount of liquid medicine injected into the base of the paulownia tree trunk is 25-100mL, the spraying on the leaves is sprayed during the growth period of the paulownia tree, and the dose of the liquid medicine sprayed is 25-50 times that injected ...

Embodiment 2

[0017] Drugs for the prevention and treatment of Paulownia arbuscular disease, containing 30mg·L of antibiotics -1 , the content of methyl methanesulfonic acid is 10mg·L -1 .

[0018] Using method is the same as embodiment 1.

Embodiment 3

[0020] Drugs for the prevention and treatment of Paulownia arbuscular disease, containing 40mg·L of antibiotics -1 , the content of dimethyl sulfate is 20mg·L -1 .

[0021] Using method is the same as embodiment 1.

Abstract

The invention discloses a compound medicine for preventing and treating paulownia witches broom. The medicine is an aqueous solution taking antibiotics and a DNA methylating agent as active components, and each liter of the medicine contains 20 to 40 mg of the antibiotics and 10 to 30 mg of the DNA methylating agent. The use method of the compound medicine comprises the following steps: uniformly mixing all the components according to the ratio, storing the components away from light, and injecting 25 to 100 mL of the uniformly mixed medicinal liquor into the pith of the base of a kiri trunk or performing leaf surface spraying according to the amount which is 20 to 50 times the injection dosage to the trunk part. The compound medicine disclosed by the invention is long in paulownia witches broom inhibition time, obvious in prevention and treatment effect, low in toxicity, high in efficiency, pollution-free to the environment and convenient to use; the disease prevention and treatment effect on young trees is 95 percent or above; and thus the compound medicine is a low-toxicity and high-efficiency novel compound medicine for preventing and treating the paulownia witches broom.

Description

technical field [0001] The invention relates to a medicine for preventing and treating forest diseases and a use method thereof, in particular to a medicine for preventing and treating Paulownia arbuscular disease and a use method thereof. Background technique [0002] Paulownia arbuscular disease is an infectious disease caused by phytoplasma. Seedlings, saplings, and large trees can all be affected. Young trees can be fatal after being infected, while large trees grow slowly, reduce their volume, and Reduce economic yield rate and yield grade. Due to the extensive use of vegetative propagation in production, Paulownia arbuscular disease spread rapidly. In recent years, the occurrence of the disease is on the rise. According to the survey, the average incidence rate reaches 50%, the severe cases reach 80%, and some serious plots reach 95%. develop. The prevention and control of Paulownia arbuscular disease generally adopts methods such as removal of diseased branches, us...
