Mahmood, 1996; Stapleton et al., 2010). China is the largest
producer of tobacco in the world and, thus, a large amount of
tobacco residue is generated during the processing of cigarettes
(Zhu et al., 2006; Li et al., 2010). Previous studies have reported that
tobacco leaf extracts significantly inhibited the movement of
nematodes within 1 h of exposure, inactivated or killed 95% of the
nematodes in 24 h and addition of leaves of tobacco markedly
reduced populations within three days (Miller et al., 1973). These
results suggest that recycled tobacco wastes may reduce nematode
infection. However, little is known about the effect of recycled
tobacco wastes on nematode infection and potential application in
the greenhouse condition.
