Abstract: To test the control effect of botanical medicine and chemical medicine joint health technology on tobacco black shank disease, in order to ascertain the further exploring feasibility, the field experiments in two areas were conducted within a year. It was shown that, the compatibility of botanical medicine, chemical synergistic agent and flumorph plus fosetyl-aluminium decreased disease index by 78.61%. To achieve the best effect, we should apply 600 g/hm2 Qinongsu, 600 kg/hm2 botanical exacts with flumorph plus fosetyl-aluminium to roots 2-3 times before or just when black shank disease occurs, with high black shank resistance tobacco varieties after three times preventions of seedling diseases, if under slightly continuous cropping obstacle.
