Damping-off diseases are caused by a complex of plant pathogens (disease inciting agents) including Alternaria spp., Fusarium spp., Pythium spp. and Rhizoctonia solani. These pathogenic fungi may cause rotting of seeds before emergence or death of seedlings after emergence.
The most disposing factors are use of non-certified disease-free seeds and excessive watering of seed-beds or field plots.
What to do:
- Always use certified disease-free seeds. If using own seeds hot water the seeds.
- Avoid overwatering of seed-beds or field plots.
