After my seeds germinate and start growing the little seedling just turns brown and collapses at the soil level. What is the problem and how can I treat it?
This is a disease called damping off. It is caused by soil borne fungi such as rhizoctonia and pythium. There is no treatment for this disease once the seeds are planted. Soil sterilization is one form of prevention and treatment against this disease. Soil sterilization can be accomplished by solarization. Use seeds treated with a fungicide for further prevention. Crop rotation also helps.
