The invention belongs to a method for preparing inula japonica plant extract and applications of the inula japonica extract. The plant material (root, stem, leaves, inflorescence and whole grass) of the inula japonica (including Inula japonica and Inula britannica) is crushed and extracted by a solvent which comprises 95% of alcohol; and the extract solution is concentrated to have the same weight with the inula japonica crushed matters, thus obtaining inula japonica extract. The inula japonica extract has obvious inhibition effects to cucumber botrytis cinerea, alternaria solani, cladosporium fulvum, colletotrichum lagenarium, sphaerotheca fuliginea, pseudoperonospora cubensis, potato phytophthora infestans, tomato phytophthora infestans and rhizoctonia cerialis; wherein the inflorescence extract has strong antibacterial activity. The inula japonica extract extracted by alcohol can be matched with suitable solvent and pesticide adjuvant to prepare britannica lactone emulsifiable solution and britannica lactione micro-emulsion of botanical fungicide. The inula japonica extract has obvious effects for preventing cucumber downy mildew, sphaerotheca fuliginea, tomato gray mold and tomato leaf mould, is especially suitable for prevention and control on the fungi diseases to economical crops such as vegetables and the like, and is a botanical fungicide with nuisanceless.

The invention discloses a blocking agent for inhibiting the infection of High Pathogenic Porcine Reproductive and Respiratory Syndrome Virus (HP-PRRSV). According to the blocking agent, a novel HP-PRRSV cell target protein called 14-3-3Epsilon protein and the inhibition targets of the receptor are found. The infection of HP-PRRSV could be significantly reduced by performing interference on the 14-3-3Epsilon gene at these inhibition targets or using inhibitor difopein of the 14-3-3Epsilon protein. These inhibition targets and difopein can be developed into a drug for preventing and curing PRRSVinfection so as to provide a brand-new idea for HP-PRRS research, prevention and cure and expand the scope of research. The invention has great significance in actual production.
