| Tomato and potato plants, but also other members of the family Solanaceae. | Late blight or potato blight. | The whole plant can be affected, i.e. stems, inflorescence, leaves and any tubers (e.g. potatoes). This oomycete forms a sparse mold-like lint at the edge of brown spots, which appear mainly on the lower surface of the foliage. Potatoes that are affected get reddish-brown spots on the skin and if you divide the potatoes, you see an irregular reddish-brownish and dry rot. |
