Minor Pest Title

Damping-off diseases (Pythium spp. Rhizoctonia solani )

Minor Pest Description

The disease is caused by Pythium aphanidermatum, Rhizoctonia solani and Aphanomyces sp. Seeds may rot in the soil before emergence (pre-emergence damping-off) or seedlings may exhibit stem canker above the soil line and/or root necrosis. Affected seedlings eventually wilt (post-emergence damping-off). The disease is favoured by high soil water content and low soil temperatures. Also dense planting without sufficient aeration enhances disease development.

Minor Pest What to do.
  • Use disease-free seeds.
  • Avoid over watering.
  • Avoid dense planting.
