Stem withering is a debilitating disease affecting Oregon crabapple, characterized by the gradual decay of its stem tissues, which impacts the plant's vigor and fruit production capabilities.

Fruit damage in Oregon crabapple manifests as physical blemishing and decay of the fruit, affecting its marketability and yield. It can occur due to abiotic stress, pests, or diseases.

Aphid infestations on Oregon crabapple primarily weaken the plant by feeding on its sap, leading to reduced vigor and potential secondary infections. Effective management involves both cultural practices and pesticide applications.

Leaf drop is a common disease impacting Oregon crabapple that can weaken and even lead to the demise of the plant. This disease is characterized by the sudden yellowing and falling off of leaves, predominantly activated in fall and spring, and is primarily caused by water stress, fungal infections, or insect infestation.

Interveinal yellowing

Interveinal yellowing is a plant disease that affects Oregon crabapple, causing the leaves to turn yellow between the veins, along with stunted growth. This can significantly reduce the plant's vitality if not treated promptly.

Fruit malformation

Fruit malformation is a disease that causes abnormal growth in fruits of Oregon crabapple, leading to significant crop loss and reduced market value.

Fruit rot is a destructive fungal disease that severely affects Oregon crabapple. It causes the fruits to rot, impacts tree health, and can significantly reduce yield. It's highly infectious but has moderate lethality.

Rust disease, caused by various fungal species, affects the health and growth of Oregon crabapple. It's characterized by orange-to-brown pustules on leaves and stems, which can be detrimental if left untreated. The severity of the condition depends on the environment and care provided to the plant.

Brown spot is a fungal disease that affects Oregon crabapple, causing unsightly blemishes and decreasing overall plant health. This infection primarily arises due to conducive moist and humid conditions and can cause irreversible plant damage if not addressed timely.

Leaf yellowing is a common condition affecting Oregon crabapple, characterized by chlorosis that can lead to reduced vigor and stunted growth. It is usually a symptom of a variety of underlying issues, from nutrient deficiencies to diseases.

Spots is a fungal disease that causes significant harm to Oregon crabapple. It manifests as black or brown spots on the leaves and stems, deteriorating the plant health and productivity. It's highly infectious but with moderate lethality.

Leaf edges turning downwards

Leaf edges turning downwards is a plant disease that affects the growth of Oregon crabapple. It typically leads to reduced photosynthesis, stunted growth, and diminished overall health of the plant.

Wounds on Oregon crabapple are physical injuries that may result from hailstone impacts, improper pruning, insect bites, or other mechanical forces. Wounds make the plant susceptible to other diseases and pests, causing significant damage and impairing growth.

Leafminer stripe

Leafminer stripe is a damaging insect that targets the leaves of Oregon crabapple, causing significant damage and reducing plant vigor. It creates stripe-like damage patterns, can affect fruit yield, and make plants more susceptible to other diseases.

Underwatering yellow

Underwatering is a common issue affecting the growth and vitality of Oregon crabapple. It results from insufficient water supply, causing dehydration, wilting leaves, and a significant reduction in fruit yield.

Leaf gall is a disease that causes abnormal growths on the foliage of Oregon crabapple. It disfigures leaves, potentially impacting photosynthesis and the overall health of the plant.
