Tomato and Potato Blight

On site we are currently experiencing blight affecting both tomato and potato crops. Blight is a serious disease of the foliage and fruit or tubers of tomatoes and potatoes which causes rotting. The disease, a fungus, is spread by wind and rain, infecting crops over a large area.

Please check your tomatoes and potatoes for any signs of blight. Also, please check adjacent plots as your neighbours may be away or not have seen our email. We need to help each other in order to prevent further spread of this disease.

Symptoms – Potatoes. First signs are brown patches on the tips and edges of leaves, sometimes with white, fluffy mould underneath. As the leaves wither, stems or haulms develop dark patches and collapse. Underground the potatoes also have dark patches, beneath which the flesh turns reddish brown, slimy and smelly as it rots.
Symptoms – Tomatoes. Leaves develop brown patches, curl up, dry out and die. Stems may also show patches and darken. Fruits turn brown, shrink and rot.

Infected material should be dealt with immediately as follows:

  • Remove and destroy infected foliage and crops
  • Ideally burned. Bag it and take it to the fire site (plot 7)
  • Bag it, take it home and place in your green waste collection bin
  • Please do not compost any diseased material
