摘要: 为验证植物源联合保健技术对黑胫病防治的大田防效,确定其研究的可行性,进行了1年多点田间试验。结果表明,植物源药剂、化学增效剂、氟吗啉·三乙膦铝3种措施联合施用能大大降低烤烟黑胫病病指,降幅达78.61%。其防治方法为:选用抗根茎病品种,在连作障碍较轻地块,在苗期用保健方法预防病害后,将植物源药剂600 kg/hm2、奇农素600 g/hm2和氟吗啉·三乙膦铝3种药剂混配,于黑胫病高发期前进行2~3次叶面喷施和灌根。

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.
