tobacco cyst nematode (Globodera solanacearum ) on flue-cured tobacco (Nicotiana tabacum (flue-cured type)) - 1402036

tobacco cyst nematode
Globodera solanacearum Miller & Gray

Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type) L.)
Descriptor: Damage
Description: Plants infected by this nematode are stunted and have reduced root systems. Roots are pruned and may have brown decayed areas. Female nematodes, the size of tobacco seed, may be seen attached to the roots. They are round and vary in color from white to dark brown. Flowering of plants may be delayed up to two months, and leaves on infected plants are greener than normal. Stunted plants may appear to recover, but they will never achieve normal size. Root examination and soil assays are necessary for accurate diagnosis.
