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 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.

Stem rot in Pigeon pea is a significant disease causing extensive damage and yield loss. Identified by soft rot on stems and foliage die-back, this disease severely impacts growth and productivity.

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.
