Abstract

The present invention relates to the field of fish trichodina prevention and control, and discloses a drug compound preparation for preventing and controlling fresh water fish trichodina. The drug compound preparation comprises, by weight, 10-50% of methylene dithiocyanate, 5-40% of chlorhexidine hydrochloride, 1-20% of a dispersing agent, 1-20% of a wetting agent, and the balance of a carrier, wherein the methylene dithiocyanate and the chlorhexidine hydrochloride are the active components. According to the present invention, the special insecticide formula for freshwater fish is provided, and the trichodina parasitising on the gill of the fresh water fish can be effectively killed; and the drug compound preparation has characteristics of rapid metabolism decomposition, killing of parasites on gills, sterilization and disinfection on damage caused by trichodina, and easy wound healing. The invention further discloses a preparation method of the drug compound preparation. The drug compound preparation of the present invention can efficiently prevent and control the fresh water fish trichodina in a low toxicity manner.

Description

technical field [0001] The invention relates to a drug compound preparation for preventing and controlling freshwater fish trichotillomantis and a preparation method thereof. Background technique [0002] Trichomonas is a free-moving parasitic ciliate-like protozoa, and is the most common parasitic disease in freshwater fish. In recent years, it has shown long onset time, wide host range, strong drug resistance, high recurrence rate, and high degree of harm Due to the lack of effective control drugs in the breeding process, trichotillomaniasis has become a major chronic disease in the breeding process. [0003] Copper sulfate ferrous sulfate powder is currently the only drug used in the national standard fishery medicine (2010 version) for the control of trichotillomantis, but it also has great disadvantages and potential safety hazards. Due to years of use, trichotillomantis has developed strong drug resistance to copper sulfate ferrous sulfate powder, and the dosage is gr...
