Problems solved by technology

[0003] At present, methods such as breeding good varieties, picking diseased branches, and using tetracycline hydrochloride are generally used for comprehensive prevention and treatment. These methods all have disadvantages such as complicated methods, long time, slow effect, ineffective effect, expensive drug price, and inability to cure the disease.
Chinese patent CN1056218A (application number is 91102455.7, title of invention is: a production method of traditional Chinese medicine preparation for preventing and treating Paulownia arbuscular disease) discloses a Chinese medicine preparation for preventing and treating Paulownia arbuscular disease, which is prepared from various traditional Chinese medicines , and its preparation method is to process and process the medicine such as screening, slicing, drying, drying, soaking, etc., the medicine has fast killing, long inhibition time, high efficiency, low toxicity and obvious control effect on Paulownia arbuscular diseases, but Its preparation method is complicated, and it is not suitable for the prevention and control of large-area Paulownia forests.

Embodiment 1

[0019] (1), preparation of medicinal solution: prepare oxytetracycline and actinomycin respectively according to oxytetracycline content of 10 mg / L, actinomycin D content of 0.01 μg / L, and α-naphthalene acetic acid content of 0.6 mg / L D, α-naphthalene acetic acid aqueous solution;

[0020] (2) Take 1000 L of oxytetracycline, 0.01 L of actinomycin D aqueous solution, and 60 L of α-naphthalene acetic acid aqueous solution and mix them evenly for later use.

Embodiment 2

[0022] (1), medicinal solution preparation: prepare kanamycin and actinomycin respectively according to the kanamycin content of 20 mg / L, the actinomycin D content of 0.03 μg / L, and the α-naphthycin content of 0.6 mg / L Bacterin D, α-Naylacetic acid aqueous solution;

[0023] (2) Take 2000 L of kanamycin aqueous solution, 0.03 L of actinomycin D aqueous solution, and 60 L of α-naphthylic acid aqueous solution and mix them evenly for later use.

Embodiment 3

[0025] (1), medicinal liquid preparation: be 30mg / L by tetracycline content, actinomycin D content is 0.05 μ g / L, and α-naphthalene acetic acid content is 0.6mg / L to prepare respectively rifampicin, actinomycin D, Aqueous solution of α-naphthalene acetic acid;

[0026] (2) Take 3000 L of rifampicin aqueous solution, 0.05 L of actinomycin D aqueous solution, and 60 L of α-naphthalene acetic acid aqueous solution and mix them evenly for later use.

Abstract

The germicide for preventing and controlling staghead of paulownia consists of antibiotic in 1000-3000 volume portions, actinomycin D in 0.01-0.05 volume portions, and alpha-naphthylacetic acid in 60 volume portions; or contains antibiotic in 10-30 mg / L, actinomycin D in 0.01-0.01 mcg / L and alpha-naphthylacetic acid in 0.6 mg / L. When it is used, the components of the germicide are mixed homogeneously and 25-75 ml the germicide is injected into the base part of the paulownia trunk. The germicide has excellent preventing and controlling effect on staghead of paulownia, low toxicity, no harm to human body and farm animal, no environmental pollution and low cost.

Description

Technical field: [0001] The invention relates to a medicine for preventing and treating plant diseases, in particular to a medicine for preventing and treating paulownia arbuscular disease and a method for using the medicine, which belongs to the field of medicine formula. Background technique: [0002] Paulownia arbuscular disease is a devastating disease of Paulownia trees. It is caused by the invasion of phytoplasma. It usually leads to premature death of young Paulownia trees, slow growth of large trees, and reduced stock volume. According to the preliminary national statistics Looking at it, the incidence rate of young trees is 1-40%, the incidence rate of large trees over 10 years old is about 50%, and in some places the incidence rate even reaches 100%, and the mortality rate of seedlings is about 5-20%. The expansion and rise have seriously affected the growth and yield of paulownia, and the direct economic loss caused by this in the whole country exceeds 100 million...
