Effect of nursery treatment and bare root dips in formulations of plant extracts on Meloidogyne incognita in tomato

Resumo

An experiment was conducted under field conditions to assess the efficacy of nursery treatments with carbofuran and root dips in three nematicidal formulations based on plant extracts (Max Raze, Max Cannon and Neem Gold) on the root-knot nematode, Meloidogyne incognita, and on growth and yield of tomato. Seedlings from the nursery bed treated with carbofuran were free from galls while those from the untreated nursery bed showed an average galling index of 2.4. Seedlings from the treated nursery bed, when transplanted into an infested field, showed better plant performance, produced more fruit, and suppressed the nematode population compared to seedlings from the untreated infested nursery bed. All plant extract formulations controlled the root-knot nematode and increased yield of tomato, though Max Raze and Max Cannon were significantly more effective than Neem Gold.
