Other Common Problems About Peanut

Brown blotch yellow edge

Brown spot, caused by the fungus Cercospora arachidicola, is a common disease affecting Peanut. It primarily causes brown lesions on leaves, stems, and pods, impacting yield and crop quality. The disease is most active during warm, moist conditions and can be managed through cultural practices and fungicides.

Non-base branch withering

Non-base branch withering is a disease that severely affects Peanut, causing its branches to wilt and dry out. This impairment significantly disrupts the plant's growth and nut production, leading to substantial yield loss.

Dark blotch is a fungal disease affecting Peanut, causing devastating yield loss. Increased moisture in soil and plant debris may promote this disease. It mainly manifests as dark leaf spots, radically decreasing plant health and productivity.

Leaf drooping in Peanut is characterized by a noticeable sagging of leaves, negatively impacting photosynthesis and overall plant vigor. This condition can substantially decrease yield and quality if not managed properly.

Leaf spot is a disease that poses a significant threat to Peanut. It promotes leaf defoliation, drastically hampers growth and reduces yield. It is caused by fungal pathogens, with the primary symptom being the appearance of brown or black spots on leaves.

Caterpillar infestation in Peanut primarily results in defoliation, affecting the plant's growth and yield. Early detection and management are crucial to minimize economic losses.

Wilting is a disease that severely impacts Peanut, causing dehydration, stunted growth and even death. Triggered mainly by pathogens such as bacteria and fungi, it can lead to significant yield losses, making it a major concern in agriculture.

Black mold is a fungal disease that affects Peanut, posing serious threats to its development and productivity. The disease manifests with characteristic dark patches, significantly reducing yield and quality.

Root malformation

Root malformation is a detrimental plant disease affecting the growth and productivity of Peanut. It deforms its root structure, making nutrient absorption difficult, subsequently causing stunted growth, weakened stem, and reduced yield.

Leaf rot is a damaging fungal disease that impacts peanut plants, causing significant yield reduction and quality deterioration. Infected plants experience discoloration, wilting, and rotting of leaves, requiring careful management measures to control and prevent the disease.

Wounds on Peanut refer to physical injuries caused by insects, machinery, hail, or other damaging elements. These can lead to weakened plant health and susceptibility to secondary infection, potentially impacting crop yield significantly.

Leafminer stripe

Leafminer stripe is a widespread disease affecting Peanut, caused mainly by Liriomyza species. It causes severe damage (such as leaf distortion and reduced yield) to the plants by feeding on the plant tissue.

Root rot is a destructive disease that significantly impacts Peanut yield and quality. It is mainly caused by fungal pathogens, notably Phytophthora spp., resulting in wilting, yellowing, and ultimately plant death. It is increasingly prevalent in warm, wet conditions and severe in poorly drained soils.

Stem rot is a serious fungal disease that affects Peanut, causing significant yield loss. The disease thrives in warm, humid conditions, causing wilting, leaf drop, and stem decay. Without effective control measures, Peanut can suffer significant damage.

Fruit withering

Fruit withering in Peanut affects the development and productivity of the plant, leading to premature fruit drop and decreased yield.

Fruit damage is a widespread complication impacting the growth and productivity of Peanut, leading to significant losses. This disorder, caused by various factors, impacts the plant's fruit quality, yield, and overall growth, necessitating preemptive measures and prompt treatment.

Lack of fertilizer

Lack of fertilizer is a detrimental condition that can severely impact the growth of Peanut, leading to stunted growth, poor yield, and reduction in the quality of produce. It is primarily caused by inadequate nutrient supply in the soil.

Whole leaf withering

Whole leaf withering is a disease affecting Peanut, leading to an overall deterioration of plant health. This disease may severely impact crop yield and quality, caused by various factors, and can be infectious and potentially lethal to the host plant.

Yellow edges is a plant disease affecting Peanut, leading to discolouration and yellowing of the leaves' edges, reducing overall yield. The pathogen thrives in cool, wet conditions and can lead to eventual plant death if untreated.

Leaf yellowing is a disease prevalent in Peanut, caused predominantly by fungal pathogens, leading to reduced yields. The condition significantly alters photosynthetic activities, inhibits growth, and potentially results in the plant's wilting if not promptly curtailed.

Leaf wilting is a disease prevalent in Peanut that leads to underdevelopment, yellowing, and ultimately wilting of the plant's leaves. This manifests in stunted growth, limited pod yield, and affects the overall health of the plant.

Plant dried up is a serious condition that can severely impact Peanut's growth and productivity, potentially decimating entire crops. It is caused by multiple factors, displaying symptoms like wilting leaves and stunted growth, and is most active in hot, dry conditions.

Underwatering dry

Underwatering is a common issue that affects Peanut, leading to stunted growth, wilting, and even death if untreated. It is caused by inadequate water supply reaching the plant's root system, disrupting normal growth and physiology.

Spots is a disease affecting the Peanut causing necrotic spots on the leaves and can drastically reduce yield. It's caused by various infections and conditions, most notably fungal pathogens. Given suitable conditions, it can rapidly spread across an entire field.
