Life Cycle:

Damage:

Causes galling of rice roots; a single plant may have up to 1,700 galls without showing signs of obvious stress.

With high infestations (12,000/v), leaves of rice seedlings become discolored and wilt. Subsequent yield is poor.

Of 100 rice varieties tested, one was resistant and 11 were tolerant to infestation by M. graminicola.

Management:

Infestation is greatly reduced in flooded fields, but can be high in irrigated soils.

In general, use of nematicides is too costly on a field-wide basis, although nematicides can be useful in seedbeds.
