Controlling Nematodes in Pome Fruit

Practical Guidelines for the short- and long- term control of nematodes

By Sheila Storey

Nematodes are microscopic worm-like organisms that
attack the roots of plants. Damaged roots result in a

Pome fruit is primarily attacked by root-lesion, dagger
and stubby root nematodes. Root-knot nematodes,
which cause the characteristic galls on roots, do not
attack pome fruit. Due to […]
