• The populations in nursery seedlings die due to this diseases
• Mycelium are hyaline and Aseptate and its has width size 5 micron
• Irregular mycelial fibers grown and thus produce irregular shape spores

Symptoms

• Seedlings killed before emergence
• Water soaking and shrivelling of stem
• Factors favouring infection:Moist soils poordrainage 90-100% R.H soil temperature 20°C
• Impact of disease symptoms shown at after sowing of seeds in seed beds
• It will reduce the seed germination percentage
• its affects the young seedlings and their stems
• lodging of seedlings due to weaken stems
• disease affected seedling are seen light brownish colour
• diseases spread through seeds and soil.

Management

• Treat the seeds with Trichoderma asperellum @ 4 g / kg or Pseudomonas fluorescens @ 10 g /kg of seeds 24 hours before sowing
• Apply P. fluorescens to soil @ 2.5 kg/ha with 50 kg of FYM
• Avoid stagnation of water
• Drench with copper oxychloride at 2.5 g/l @ 4 l/sq.m
• Soil drenching with Copper oxychloride 0.25%
• avoid shade places for nursery establishment
• use recommended seed rate
• avoid flooding type of irrigation and maintain optimum moisture level in nursery
• use Thiram or Capton @ 4g/ kg of seeds for seed rate
