The invention relates to an anticoccidial traditional Chinese medicine preparation and a preparation method thereof. The anticoccidial traditional Chinese medicine preparation mainly comprises the following components: giant knotweed, notoginseng, rhubarb and halofuginone. The anticoccidial traditional Chinese medicine preparation has the characteristics that the anticoccidial traditional Chinese medicine preparation not only can quickly inhibit and kill coccidia oocysts, but also effectively stops bleeding, quickly repairs the intestinal impaired mucosa, effectively prevents the coccidiosis from recurring, and does not affect the feed-meat ratio of poultry; meanwhile, the solution form is adopted, and the anticoccidial traditional Chinese medicine preparation can be evenly dispersed in water, so that the anticoccidial traditional Chinese medicine preparation is convenient to take, waste is reduced, the dose is ensured, the bioavailability is improved, and a drinker is not blocked.

The invention discloses a compound composition and a preparation thereof. The compound composition is prepared from methylsulfonyl azole and azoxystrobin, wherein the chemical name of methylsulfonyl azole is 2-(4-fluorophenyl)-5-methylsulfonyl-1,3,4-oxadiazole; the weight ratio of methylsulfonyl azole to azoxystrobin is (20-1):(1-20), and preferably (10-1):(1-10); and the compound composition is 0.1-90 percent of a bactericide. The compound composition and preparation thereof have remarkable synergetic effect for preventing and controlling diseases, and can be used for improving the germicidal efficiency, reducing drug usage, and reducing environment pollution and pesticide residue; and generation of drug resistance of bacteria can be retarded or resisted due to increase of acting sites. The composition and bactericide do not have remarkable adverse influence to tested crops, have high safety, and accord with the safety requirement for pesticide preparations.

The invention provides a compound composition, in particular to a compound composition containing 2-p-fluorophenyl-5-methylsulfonyl-1,3,4-oxadiazole and thiodiazole copper, wherein the weight ratio of 2-p-fluorophenyl-5-methylsulfonyl-1,3,4-oxadiazole to thiodiazole copper is (20-1):(1-40). Compared with each of 2-p-fluorophenyl-5-methylsulfonyl-1,3,4-oxadiazole and thiodiazole copper, the compound composition provided by the invention has an obvious synergistic effect on bacterial diseases of crops, improves the bactericidal effect, reduces pesticide cost, environmental pollution and pesticide residue, and is conductive to overcoming the generation of pesticide resistance. The compound composition provided by the invention has no obvious adverse effect on tested crops, ensures normal leaf color, growth and the like, has high safety, meets the safety requirements of pesticide preparations and plays a favorable control role on bacterial diseases of crops.

The invention belongs to the technical field of pesticides and in particular relates to a traditional Chinese medicine type crop seed-dressing agent and a using method and an application thereof. The Chinese medicine type crop seed-dressing agent is mainly prepared from the following ingredients: 70-75% of traditional Chinese medicine powder mixture, 15-25% of sulfur powder, and 2-5% of kaolin or talcum powder, wherein the traditional Chinese medicine powder mixture is prepared from the following ingredients in part by weight: 20-25 parts of crushed garlic bulblet, 20-25 parts of crushed Houttuynia cordata, 12-20 parts of crushed purslane, 4-5 parts of crushed folium artemisiae argyi, 4-5 parts of crushed ginkgo leaf, and 4-5 parts of crushed sweet wormwood. The seed-dressing agent is used for preventing and killing pathogenic bacteria and fungi in crop seeds, soil and water body, is used for seed-dressing and can be sown in the same day, has an effective rate up to more than 90%, is non-toxic, has good water permeability and gas permeability, does not affect the life and the respiration of the seeds, and can reduce and avoid damage caused by rats, birds trouble and soil insect damage.
