在烤烟黑胫病单独发生的地域施用恶霜锰锌，对黑胫病的防效幅度为85.5％～88．2％。在根结线虫病与黑胫病同时发生的地域，分别施铁灭克和恶霜锰锌，前者对根结线虫病的防效幅度为51．9％～52．3％，后者对黑胫病的防效幅度为80.3％～88.3％；单独施铁灭克，对根结线虫病的防效幅度的48．5％～51．3％，对黑胫病的防效幅度为13.8％－19．4％；单独施恶霜锰锌，对根结线虫病的防效幅度为2．3％～2．7％，对黑胫病的防效幅度为66．4％～78.6％。
In the area where flue-cured tobacco black shank occurred alone, vancomycin, manganese and zinc were applied, and the control efficacy against black shank was 85.5% -88.2%. In the area where root-knot nematode disease and black shank occurred simultaneously, the control efficacy of the former was 51.9% ~ 52.3% for the root-knot nematode disease, and the latter was negative for black The prevention and cure rate of shank was 80.3% ~ 88.3%. When applied alone, the control effect on root-knot nematode disease was 48.5% ~ 51.3% and that of blackleg was 13.8% -19.4% respectively. The control efficiency of Mn-Zn alone was 2.3% -2.7% for root-knot nematode disease and 66.4% -78.6% for black shank.
