Abstract: Tobacco root-knot nematode disease is widespread in the tobacco-growing areas of southwestern China and seriously affects the yield and quality of tobacco. In order to alleviate the harm imposed by this disease on tobacco plants, a field plot trial was carried out to investigate the control effectiveness of different agents and materials and their influence on tobacco growth. The results showed that 0.5% abamectin granules gave the highest control effectiveness (73.95%), followed by oyster meal (60.94%); that the agronomic characters of the tobacco plants treated with 0.5% abamectin granules were obviously better than those of the control plants; and that the plants treated with oyster meal and compound acid-regulating materials grew more vigorously than the control plants. In conclusion, 0.5% abamectin granules have a good control effectiveness on tobacco root-knot nematodes, and oyster powder and compound acid-regulating materials have promising potentials of application.
