Abstract

The invention provides a medicament for preventing and controlling paulownia witches broom, and a using method thereof. The medicament is aqueous solution taking rifampicin and DNA methylation agent as active components, and each liter of the medicament contains 90 to 110 mg of rifampicin and 50 to 70 mg of DNA methylation agent. The using method specifically comprises: taking the components according to proportioning amount; mixing the components well; storing the mixture in a dark place; and injecting 25 to 50 ml of liquid medicament mixed well into the pith of a paulownia trunk base or spraying the leaf surfaces with the liquid medicament of which the injection dose is 50 to 100 times that of the liquid medicament for the trunk base. The medicament having the advantages of long inhibition time for paulownia witches broom, obvious prevention-control effects, low toxicity, high efficiency, no harm to human and animals, no pollution caused for environment, use convenience, prevention-control effect up to 100 percent for young trees and current-year prevention-control rate up to 90 percent is a novel effective way to use medicaments to prevent and control 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 has been on the rise. According to the survey, the average diseased plant rate is 50%, the severe one is 80%, and some serious plots are as high as 100%. This directly affects the economic and ecological benefits of Paulownia and seriously restricts the Paulownia industry. dev...

Problems solved by technology

In recent years, the occurrence of the disease has been on the rise. According to the survey, the average diseased plant rate is 50%, the severe one is 80%, and some serious plots are as high as 100%. This directly affects the economic and ecological benefits of Paulownia and seriously restricts the Paulownia industry. development of

[0003] 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 it is not suitable for the prevention and control of large-area paulownia forests.

Chinese patent ZL200610107024.2 (invention name: medicine for preventing and treating Paulownia arbuscular disease), the drug is made by mixing oxytetracycline, actinomycin and α-naphthalene acetic acid. long, the control effect is obvious, but there are problems such as tetracycline, oxytetracycline and other drugs remaining for a long time, which will pollute the environment
