The present application belongs to the technical field of virus prevention and control of plants, and particularly relates to a formula of an elicitor for Passiflora edulis EAPV and TeMV and an application method thereof. The elicitor is composed of sophoramine and ginsenoside Rh2, and the preferred concentration is 160 mg / L for each. The results of a pot experiment show that the virus content of TeMV and EAPV in Passiflora edulis plants is significantly lower than that of the water control, the virus index is 33.12, and the relative control effect reaches 65.57%, which is better than that of a commercial plant immune elicitor "A Tailing". In a field experiment, the preferred application method is adopted, i.e. spraying once at the seedling stage of 4-5 leaves and at the end of flowering and the beginning of fruiting, and the disease index at the harvest stage is 23.15, and the relative control effect reaches 72.30%, which is significantly better than that of "A Tailing", and the leaves of the treated plants are flat and smooth, and have few disease spots. The safety experiment shows that the concentration of 160 mg / L has no adverse effect on Passiflora edulis. The present application has simple components, easily available raw materials, low cost, simple operation, only two times of spraying, and has a good application prospect.

The invention belongs to the technical field of xanthoxylin application, and particularly discloses application of xanthoxylin WGX-50 in preparation of a medicine for treating pathogenic bacteria induced broiler inflammatory depletion diseases, and the xanthoxylin WGX-50 can be used as a poultry feed additive. In-vitro experiments show that 20 [mu] M of WGX-50 significantly alleviates the toxicity of LPS-induced chicken macrophages, and the cell activity is improved to 103.74%. In-vivo 21d broiler chicken feeding tests prove that by adding 100mg / kg WGX-50 into daily ration, a synergistic effect can be generated: the total antioxidant capacity of an organism is remarkably enhanced, and the level of pro-inflammatory cytokines is reduced; meanwhile, the average daily gain of the broiler chickens is remarkably increased, the feed-gain ratio is reduced, and the metabolic rate of key nutrient substances such as crude protein, calcium and phosphorus is increased. According to the invention, a brand new solution is provided for the WGX-50 in the aspects of precise prevention and control of poultry inflammatory depletion diseases and improvement of breeding benefits through a clear action mechanism and dosage.
