Through field trials, four kinds of foliar fertilizer, “green piece”, “big cloud”, “Jinyun big-120” and “high-phosphorus potassium” Study on Disease Prevention and Treatment. The results showed that the four kinds of foliar fertilizer had certain control effects on TMV, CMV, PVY and TRSV, and promoted the growth and development of tobacco plants to varying degrees. Among them, “Dazhong Zhongtian” (TMV), 48.4% (CMV), 29.4% (PVY) and 54.7% (TRSV) respectively, and significantly increased the growth and development of tobacco plants.
