Population density of Meloidogyne incognita under stress of different cropping sequences
Population density of Meloidogyne incognita under stress of different cropping sequences
W.M.A. El-Nagdi and M.M.A. Youssef†
ABSTRACT
Five different cropping sequences including cucumber, dry common bean, cowpea, maize and sesame plants
replacing sugar beet for controlling root-knot nematode, Meloidogyne incognita resulted that sugar beet-Hybrid
maize and sugar beet-sesame cropping sequences proved most effective against root-knot nematode as they reduced
nematode parameters as indicated by the number of galls, egg-masses and hatched juveniles on roots. Consequently,
they lowered rates of nematode population ranged from 0 and 0.01, respectively. However, the higher nematode
populations were supported rest crops. It is concluded that use of poor or non host crops may be beneficial for
controlling root-knot nematode population densities in intensive cropping system.
