Control strategies against the rice root-knot nematode (Meloidogyne graminicola):

• Switching to direct-seeded rice (DSR) actually aggravates and increases M. graminicola damage because aerobic, well-drained soil conditions facilitate rapid juvenile invasion (flooding in transplanted rice naturally suppresses it).
• In commercial rice farming practice, the most popular, cost-effective, and practical control method is chemical seed soaking/treatment and nursery seedling root dip / drenching using nematicidal protectants (carbosulfan, carbofuran, or fluopyram) to protect vulnerable seedling root systems prior to transplanting.
