How to Treat Stem rot Disease on Pigeon pea?

Non pesticide

Crop Rotation: Rotate Pigeon pea with non-host crops to reduce soil-borne pathogen loads.

Proper Planting: Ensure good drainage and avoid overcrowding to reduce moisture retention and stem rot risk.

Pesticide

Fungicidal Treatment: Apply approved fungicides at the onset of rainy periods or when symptoms first appear.

Systemic Fungicides: Use systemic fungicides that can penetrate the plant to control the spread of the infection internally.

When is Stem rot Most Active Period on Pigeon pea?

Stem rot is most active during the warm, wet seasons when high moisture and favorable temperatures accelerate fungal growth.

Infectivity

Moderately

The disease spreads moderately between proximate plants through soil and water contact.

Lethality

Highly

If unchecked, stem rot can kill Pigeon pea, especially during peak disease cycles.

FAQs on Pigeon Pea

What are the most visible early symptoms of stem rot in Pigeon pea?

Early symptoms include water-soaked lesions at the stem base, which later become soft and brown.

Can stem rot in Pigeon pea be completely cured once it appears?

Complete cure is challenging; management focuses on controlling spread and minimizing impact.

How often should fungicides be applied to control stem rot in Pigeon pea?

Fungicides should be applied at the start of the wet season or when the first symptoms appear, following the label's direction.

Are there any resistant varieties of Pigeon pea to stem rot?

Certain varieties show more resistance than others; consult local agricultural extensions for suitable options.

How does crop rotation help manage stem rot in Pigeon pea?

Rotating Pigeon pea with non-host crops reduces the persistence of pathogens in the soil.

Can stem rot be spread via contaminated tools?

Yes, the disease can spread through tools used on infected plants. Sterilizing tools can prevent this.

Other Common Problems About Pigeon pea

Wounds in Pigeon pea involve physical damage that can lead to secondary infections affecting growth and yield. Proper care and management are essential to minimize impact and encourage plant recovery.

Yellow edges is a disease affecting Pigeon pea that leads to yellowing of leaf margins and potential yield reduction. Proper management is crucial for maintaining plant health and crop productivity.

Leaf wilting in Pigeon pea primarily affects the plant’s ability to transpire and photosynthesize effectively, leading to reduced growth and yield. This condition can signify underlying issues ranging from water stress to infections.

Root rot in Pigeon pea severely impacts growth, often leading to plant death if untreated. The disease stunts growth, causes wilting, and results in yellowing and rotting of roots.

Root malformation

Root malformation in Pigeon pea generally involves distorted or abnormal root growth which affects nutrient uptake and plant stability, leading to stunted growth and possibly reduced yields.

Fruit damage in Pigeon pea primarily affects pod development and seed quality, causing significant yield losses. This disease manifests as deformations and discolorations on the pods, severely impairing crop viability and market value.

Dark blotch is a severe fungal disease affecting Pigeon pea, causing yield reduction and plant weakening. Early detection and management are crucial for minimizing damage.

Black mold significantly impacts Pigeon pea, causing reduced vigor, yield losses, and quality degradation. It thrives in humid environments and can rapidly spread if not managed properly.

Non-base branch withering

Non-base branch withering in Pigeon pea primarily results in the dying of branches from their bases, significantly impacting the plant's productivity and survival. The disease disrupts the plant's vascular system, leading to stunted growth and premature leaf drop.

Whole leaf withering

Whole leaf withering is a critical disease affecting Pigeon pea, causing significant leaf droop, discoloration, and potentially plant death, severely impacting yield and quality of the crops.

Leaf yellowing is a notable disease impacting Pigeon pea, leading to diminished growth and lower yield. It primarily manifests through yellowing leaves, potentially stemming from nutrient deficiencies, water stress, or infections.

Spots' disease is a fungal infection impacting Pigeon pea, causing physical damage and yield reduction. It primarily manifests as leaf discoloration, which progresses rapidly under favorable conditions, necessitating timely management strategies.

Leafminer stripe

Leafminer stripe, impacting Pigeon pea, presents as distinct trails or burrows in leaves caused by larvae, adversely affecting photosynthesis and plant health. This disease can significantly reduce crop yields.
