| Image | Subject Name | Scientific Name | Description |
|---|---|---|---|
| 4825028 | Neonectria canker | Neonectria galligena | rough bark at root collar. |
| 4822090 | Neonectria canker | Neonectria galligena | Red-orange spherical perithecia wich occur singly or in clusters in the fissured bark of infected stems |
| 4822058 | pitch canker | Fusarium subglutinans | Mortality of upper main stem |
| 4824080 | pitch canker | Fusarium subglutinans | Basal swelling at root collar. |
| 4824077 | Fusarium wilts, blights, rots and damping-off | Fusarium spp. | Affects lateral (feeder) and tap roots. Tap root may exhibit varying degrees of resin soaking. |
| 4824032 | pitch canker | Fusarium subglutinans | Dieback of infected seedling. |
| 4824014 | Cylindrocladium root diseases | Cylindrocladium spp. | Damaged seedlings infected with C. floridanum. Lack of aeration as foliage mats (or lays down) down causes disease to spread across tray. |
| 4822057 | pitch canker | Fusarium subglutinans | Mortality ("flagging") of terminal shoot |
| 4822055 | pitch canker | Fusarium subglutinans | Mortality ("flagging") of infected terminal/branch shoots in mature trees |
| 4822084 | Neonectria canker | Neonectria galligena | Red-orange perithecia occur singly or in clusters in the fissured bark tissue of infected trees |
| 4822083 | Neonectria canker | Neonectria galligena | Burlike galls |
| 4822056 | pitch canker | Fusarium subglutinans | Severe mortality ("flagging") of infected terminal/branch shoots in mature trees |
| 4822088 | Neonectria canker | Neonectria galligena | Distinctive "target-like" canker in stem |
| 4822089 | Neonectria canker | Neonectria galligena | Red-orange spherical perithecia wich occur singly or in clusters in the fissured bark of infected stems |
| 4823043 | pitch canker | Fusarium subglutinans | "Flagging" of infected terminal |
| 4824076 | Fusarium wilts, blights, rots and damping-off | Fusarium spp. | Affects lateral (feeder) and tap roots. Tap root may exhibit varying degrees of resin soaking. |
| 4822042 | Fusarium root rot and wilt | Fusarium oxysporum | Thinning crown of infected tree |
| 4822043 | Fusarium root rot and wilt | Fusarium oxysporum | Distinctive pale to dark brown (sometimes with a purplish hue)staining or discoloration of the xylem. This soil borne fungus enters the roots by direct penetration or through root wounds during transplanting/landscape maintance, or vectored by feeding injury caused by plant parastic nematodes. Once inside a susceptible host, the fungus enters the xylem and colonizes the vascular system restricting water flow. |
| 4825004 | Cylindrocladium blight and root rot | Cylindrocladium scoparium | High humidity conditions and dense seedling spacing results in poor air movement and drying beneath seedling foliage which can increase chance of infection. |
| 4825005 | Cylindrocladium blight and root rot | Cylindrocladium scoparium | High humidity conditions and dense seedling spacing results in poor air movement and drying beneath seedling foliage which can increase chance of infection.on |
| 4825002 | Cylindrocladium blight and root rot | Cylindrocladium scoparium | High humidity conditions and dense seedling spacing results in poor air movement and drying beneath seedling foliage which can increase chance of infection. |
| 4825027 | Neonectria canker | Neonectria galligena | Hypertrophied bark in crown. |
| 4825029 | Neonectria canker | Neonectria galligena | Perithecia on bark. |
| 4824078 | pitch canker | Fusarium subglutinans | Symptomatic wilting of terminal of an infected seedling. |
