MainImg

Brown spot is a disease affecting the Common pear plant, particularly caused by fungus Coccomyces hiemalis. It causes browning of leaves and significant yield loss, posing threats to pear farming.

MainImg

Gall is a plant disease, predominantly caused by bacteria and certain insects, which forms abnormal outgrowths on Common pear. It severely hampers the growth, development, fruit production, and overall health of the plant.

MainImg

Leaf rot is a severe disease affecting Common pear primarily caused by aggressive fungal pathogens and poor environmental conditions. It leads to decay, discoloration, and wilting of leaves, impacting the plant's vitality and yield quality.

Spider mite infestation leads to significant damage on Common pear, with symptoms such as stippling, bronzing of leaves, and webbing. This can disrupt photosynthesis and ultimately weaken the plant.

Stem cracking is a detrimental plant disease significantly affecting Common pear. It impairs the growth and quality of the plant, causing cracks in the stem and eventually leading to premature fruit dropping and poor yield.

Leaf malformation

Leaf malformation is a plant disease that affects Common pear, causing curling and yellowing of leaves, hindering the normal growth and development of the plant. Appropriate diagnosis followed by suitable treatment and preventive measures can control this ailment.

Fruit malformation

Fruit malformation in Common pear leads to abnormal growth and development of fruit, affecting yield quality and marketability. It's usually caused by a combination of factors like pests, nutritional imbalances, and environmental conditions.

Rust disease is a fungal infection affecting Common pear. The disease marks the foliage with orange or yellow-colored spores resulting in defoliation and weakening of the plant, compromising fruit production and plant longevity.

Interveinal yellowing

Interveinal yellowing is a plant malady that affects Common pear by creating yellow patches between the veins of its leaves, leading to significant nutrient deficiencies and weak growth. It's usually triggered by nutrient imbalances in the soil.

Stem rot in Common pear is a destructive disease that leads to deterioration and eventually plant death. Early detection and management are vital for controlling its spread and preserving Common pear health.

Black mold is a lethal fungal disease affecting the Common pear. It causes severe fruit blemishes, impairing growth and resulting in significant yield loss. Prompt detection, correct diagnosis, and effective control measures are critical to mitigating this disease's impacts.

Leafminer stripe

Leafminer stripe is a destructive foliar disease primarily affecting Common pear. It's caused by the larvae of a species of moths, creating yellow or white tunnels on leaves. The disease decreases plant aesthetic value and overall yield.

Leaf gall primarily affects Common pear by inducing abnormal growths or swellings on leaves and stems. This disease can decrease the plant's aesthetics and, in severe cases, impair photosynthesis and growth.

Leaf wilting is a widespread disease impacting Common pear drastically, leading to water loss and rapid decline of plant's health. The frequent symptoms include leaf discoloration and reduced growth, primarily caused by drought stress and specific pathogens.

Scale insects severely affect Common pear, causing stunted growth, leaf yellowing, and fruit damage. Controlling these pests is crucial for maintaining healthy pear trees.

Large spot mold

Large spot mold is a fungal disease that affects Common pear, causing defoliation and fruit spots, diminishing fruit quality and yield. It thrives in warm, humid conditions, and is managed through cultural practices and fungicides.

Dark spots, a common disease in Common pear, degrades the quality of fruit and leaves. It's primarily caused by a fungal pathogen and can significantly impact fruit yield and plant health if not managed effectively.

Leaf drop in Common pear results in premature shedding of leaves, affecting the tree’s vigor and fruit production. The disease can be influenced by various pathogens and environmental conditions, compromising the health and yield of Common pear.

Aphids are small sap-sucking pests that significantly affect the health and vigor of Common pear. They feed on the sap, leading to weakened growth, deformation of leaves, and reduced fruit quality.
