Description of Sudden oak death (Phytophthora ramorum) |
Description: Fungal-like pathogen affecting a range of woody species |
|
Damage caused by Sudden oak death (Phytophthora ramorum) |
Damage: Bleeding cankers (dark red to black sap oozing from the trunk); may progress to the point of girdling the stem, resulting in rapid death of the tree. Symptoms following stem girdling are rapid, uniform death of the crown, with shriveled leaves remaining attached to the stems even after death. Notifiable disease. |
|
Cultural control of Sudden oak death (Phytophthora ramorum) |
Cultural control: Notify FERA (Food Environment Research Agency). Grow resistant species. Burn infected material. Good hygiene practices (sterilize equipment between pruning susceptible plants). Avoid wounding plants to reduce infection possibilities. |

Biological control: None |
|
Chemical control/method of application for Sudden oak death (Phytophthora ramorum) |
Chemical control/method: None |
|
Description of Cucumber mosaic virus |
Description: A viral infection of cucumbers and tother members of Cucurbitaceae |
|
Damage caused by Cucumber mosaic virus |
Damage: General stunting of the plant, with a reduction in yield and distorted fruits. Leaves become mottled with yellow. |
|
Cultural control of Cucumber mosaic virus |
Cultural control: Selection fo resistant cultivars, such as Cucumber 'Crispy Salad'. Control of weeds around the garden prevent the virus from surviving on alternative host plants. Aphid control reduces risk of transmission. |
|
Biological control of Cucumber mosaic virus |
Biological control: None |
|
Chemical control/method of application for Cucumber mosaic virus |
Chemical control/method: None |
|
Description of Potato leaf curl virus |
Description: Viral infection of potatoes, which can affect or be hosted on other solanaceous plants. |
|
Damage caused by Potato leaf curl virus |
Damage: Rolling of lower leaves, sometimes extending to upper foliage. Leaves are often dry and crisp, with brown margins. Plants may be stunted and general crop yield is reduced. |
|
Cultural control of Potato leaf curl virus |
Cultural control: Use only certified seed potatoes from reputable distributors. Apply effective aphid control programs to limit the spread of the disease. Control weeds to reduce risk of infection from alternate hosts. Remove and burn infected plants. Crop rotation. |
