Why Does Garden pea Suffer From Root Rot?
Garden pea, also known as Chinese Pea, Honey Pea, Shelling pea, Green pea, Pea
Root rot is a pathological condition in Garden pea, causing severe damage to the plant's root system, impairing nutrient absorption, and eventually leading to plant death. It’s caused by several soil-dwelling fungi or bacteria and is heightened by overwatering and poor drainage.

Symptom Analysis

Externally, Garden pea exhibit wilting, yellowing of leaves, stunted growth, and loss of vigor. Upon examining the roots, a brown-black discoloration, root decay, an unpleasant smell, and a water-soaked appearance can be discovered.

What Causes Root rot Disease on Garden pea?

Fungi
Species like Phytophthora, Fusarium, and Rhizoctonia often cause root rot, attacking the roots' vulnerable areas.
Bacteria
Bacterial pathogens such as Pseudomonas spp. and Erwinia spp. can turn root tissue into a rotting mass.
Overwatering
Excessive or frequent watering can result in waterlogged soil that facilitates fungal or bacterial growth.
Poor drainage
Insufficient soil aeration due to compaction and lack of drainage favors the development of anaerobic conditions, promoting root rot incidence.

How to Treat Root rot Disease on Garden pea?

Non pesticide
Proper watering practices: Avoid overwatering or waterlogging soil, favoring sufficiently moist but well-drained conditions to inhibit the growth of the pathogens.

Adequate planting density: Maintain an optimal plant density to ensure effective airflow and reduce the chances of spreading the disease.
Pesticide
Fungicide application: Use fungicides like mefenoxam or fosetyl-Al, as per label instructions, can help manage the fungal-induced root rot.

Bactericide application: Applying copper-based bactericides can help control the bacterial pathogen populations.

Lethality

Root rot is highly lethal for Garden pea, causing significant damage to the root system, leading to plant death if not managed timely.

FAQs on Garden Pea

Can a plant recover from root rot?
If diagnosed early, root rot may be treatable. However, severe cases usually result in plant death, thus early identification and management are vital.
Is root rot infectious?
Yes, root rot is highly infectious. The pathogens can persist in soil for multiple seasons, spreading through contaminated soil, tools, or water.
Does overwatering cause root rot?
Yes, overwatering leads to waterlogged soil, creating an environment conducive for root rot pathogens.
How can I prevent root rot?
Preventive measures include proper watering, planting resistant varieties, maintaining optimal plant density, and practicing crop rotation.
How does root rot affect Garden pea growth?
Garden pea affected by root rot normally shows stunted growth due to the impairment of nutrient uptake from the roots.
Why are my Garden pea's leaves turning yellow?
Yellowing leaves is a symptom of root rot in Garden pea, usually caused by the inability of the rot-infected roots to absorb and distribute necessary nutrients.
