Anthracnose

Fungal disease that causes dark lesions, spots, and other damage on leaves, stems, fruits, and flowers of various plants, including trees, shrubs, and crops

Apple Scab

a fungal disease that affects apple trees

Black Spot

physiological plant disorder that affects some grape varieties (ex. Concord) It is essentially a potassium deficiency that causes the leaves on a vine to turn purple and eventually black as chlorophyll is lost.

Botrytis

a necrotrophic fungus that mostly affected wine grapes but other plant species can be hosts (also known as gray mold)

Canker

a localized dead (necrotic) area on branches, trunks, or roots

Cedar-Apple Rust

In virtually any location where apples or crabapples and eastern red cedar coexist, cedar apple rust can be a destructive or disfiguring disease on both the apples and cedars ( a disease caused by a type of fungus)

Crown Gall

Crown gall causes rough, woody, tumor-like galls to form on roots, trunks and occasionally branches of many different trees and shrubs. (crown gall is a type of bacterium)

Fire blight

a bacterial disease that primarily affects apple, pear, and other plants in the rose family

Powdery Mildew

a common plant disease caused by fungi, characterized by a white, powdery growth on leaves, stems, and sometimes flowers and fruit, that can cause cosmetic damage and, in severe cases, reduce plant vigor

Root Rot

a plant disease where a plant's roots decay and break down, often caused by overwatering, poor drainage, or fungal/bacterial infections, leading to wilting, stunted growth, and potentially plant death

Frost/Freeze Injury

when ice forms inside the plant tissue and injures the plant cells

Iron Deficiency

occurs when a plant can't obtain enough iron from the soil, leading to yellowing of leaves (chlorosis), especially between the veins, and stunted growth

Leaf Scorch (drought/winter burn)

may result from hot, dry weather in summer or from strong, dry winter winds when the ground is frozen

Nitrogen Deficiency

stunted growth, yellowing of older leaves (chlorosis), and reduced overall vigor, impacting photosynthesis and protein synthesis ( symptoms appear similar to iron deficiency)

Pot-Bound Roots

the roots have grown so much that they fill the entire pot, forming a tight, hard ball that restricts growth and can lead to plant stress or even death

String Trimmer Injury

often called "weedeater damage" or "mower blight," occur when the string trimmer's line or mower deck damages the bark and cambium layer of trees and shrubs, leading to potential harm or death

2,4-D Injury

a synthetic auxin, causes distorted growth, including cupped or curled leaves, stunted growth, and twisted stems, often due to herbicide drift or misuse
