Drug for controlling European foulbrood of Chinese bee and preparation method thereof

Abstract

The invention discloses a drug for controlling European foulbrood of Chinese bee and a preparation method thereof, and relates to the technical field of bee disease control. The drug comprises the following raw materials in parts by weight: 25 to 35 parts of andrographis paniculata, 20 to 30 parts of cyrtomium fortunei, 15 to 25 parts of plumbagella micrantha, 10 to 20 parts of spina gleditsiae, 10 to 20 parts of sargentodoxa vine, 20 to 30 parts of magnolia cortex, 20 to 30 parts of honeysuckle flower, 15 to 25 parts of coptis, and 7 to 12 parts of rice vinegar. The components are compoundedto generate a synergistic effect; the drug has a strong effect on killing pathogenic bacteria of European foulbrood; the pathogenic bacteria in larvae and honeycomb can be killed quickly; the recoveryof ill bees is promoted, the infection rate is reduced, the curative effect is prominent and long lasting; and the drug can replace antifungal western medicines, has little side effect, and can reduce economic loss caused by European foulbrood.

Description

technical field [0001] The invention relates to the technical field of bee disease prevention and control, in particular to a medicine for the prevention and treatment of Chinese bee larval rot and a preparation method thereof. Background technique [0002] European larval rot is a bacterial infection of bee larvae that occurs in many countries around the world. Occurrence is more common in China, while the occurrence of western bee species is less. The causative bacteria of European larval rot is Apis coccus hives, and the rest are secondary bacteria, such as Bacillus alveoli, Bacillus lateralis and its variant Streptococcus apis. The disease mostly occurs in early spring and late autumn, which is caused by large temperature changes and poor feeding and heat preservation. It mainly harms larvae and can cause larvae to rot. Make the bee colony lose its vigor and production capacity. [0003] At present, the general method for treating this disease is to adopt antifungal d...

Problems solved by technology

[0003] At present, the general method for treating this disease is to adopt antifungal drugs, such as adopting 0.1%-0.2% bromogeramine solution to spray bees and bees, not only the therapeutic effect is not good, but also the toxic and side effects of this class of drugs are strong, which is not conducive to the development of bee colonies. It also pollutes the quality of honey

In the existing method, pure Chinese herbal medicines are also used for treatment. During use, the Chinese herbal medicines are boiled into a medicinal juice and then blended with syrup and then fed. Although the toxic and side effects are small, or even have no side effects, the drug effect is not ideal.
