Objectives

• To identify the hot spot areas for mulberry parasitic nematodes.
  • To assess the efficacy of safe nematode control agents like biocontrol, biofertilizers, botanicals, organic amendments, etc.
  • To evolve integrated nematode management.

Important findings

The nematodes Meloidogyne incognita,Rotylenchusreniformis; species of Helicotylenchus,Rotylenchus,Xiphenema,Hoplolaimusand Longidorus wereencountered in the mulberry gardens.  Meloidogyne incognitain mulberry reduces the plant height by 16.92% at an inoculum level of 10,000 J2/ plant.

Appication of any one of the following organic amendments or chemicals for effective nematode management is recommended.

• Neem cake: 340 g/plant.
• Pongamia cake: 340 g/plant.
• Phorate 10 G: 1g/plant.
• Carbofuran 10 G: 1 g/plant.

Use of organic amendments not only controls the nematodes, but also increases the beneficial microbes which may reduce the disease incidence.
