Root rots are an important yield-limiting factor in lentil and pea production. The primary causal agents of root rot of peas and lentils are the fungal pathogens Rhizoctonia solani and Fusarium species and the fungal-like water mold pathogens Aphanomyces euteiches and Pythium species.
How do you treat root rot on pea plants?
How to Treat Peas with Aphanomyces Root Rot. Aphanomyces root rot can often be combated by liberal fertilization – if roots are encouraged to grow fast and healthily, they should be able to outstrip the decay of the disease. Nitrogen can be applied to suppress the spread of the fungus.

Can root rot be cured?
Once root rot is identified, you must determine if the plant can be saved. If the entire root system has already become mushy, it is too late to save the plant.

Does bottom watering cause root rot?

Why are my peas not doing well?
Any number of poor growing conditions can also attribute to garden peas not producing. Cold, wet springs or hot, dry weather can impede the development of root nodules and inhibit nitrogen fixing. Planting peas too late in the season can cause the plants to turn yellow and die before setting pods.
