Root-knot nematodes

: Root-knot nematodes: the typical root galls should not be confused with nitrogen fixing nodules

Cause	Meloidogyne hapla
Damage	Not a major problem in traditional peanut areas, but may become important in new production areas.
Symptoms	Typical root galls are formed and, in severe cases, plants are stunted.
Management options	No action is possible in an affected crop, except confirming nematodes as the cause of the damage. Chemical There are no chemicals registered for use against nematodes in peanuts. Cultural Rotation with cotton, sorghum or maize will reduce the population. Chemical registrations and permits Check the Australian Pesticides and Veterinary Medicines Authority chemical database and permit database for chemicals registered or approved under permit to treat this disease on the target crop in your state or location. Always read the label and observe withholding periods.
