Tomato leaf diseases are a big problem to the vegetable gardener as some lesser ones display the same symptoms as really virulent ones.
If your tomato plant leaves display any of the following symptoms, then you may have cause for concern:
Dark spots on the leaves with rings surrounding them may signify Early Blight which is a fungus which lives in the soil over the winter. It can be introduced into the garden on new plants and is most likely to develop in wet weather.
Drooping and yellowing of leaves at the base of your tomato plant signify Fusarium Wilt.
Small dark spots on both sides of older leaves, which grow and become greyish brown may signify Grey Leaf Spot. The centre of the spot will break and drop out and the remainder of the leaf will yellow and drop. This disease usually develops in warm damp conditions.
Shiny irregular grey blotches on the leaves possibly mean Late Blight is infecting your plants. This is a very serious condition and you should contact your local Ministry of Agriculture or Department of Food for help with identification. The fungus spreads rapidly in cool, wet conditions. However, if the grey blotches have tiny dark spots within them, it may well be Septoria Leaf Spot, which is not nearly so serious and can be treated.
Yellow gashes on the upper side of the tomato leaf and a pale fine grained fungus on the bottom signify the presence of Powdery Mildew.
A blotchy appearance to the leaves may mean that your plants have Tobacco Mosaic Virus.
Leaves turning yellow and dry but which do not wilt, possibly with v shaped lesions may signify Verticillium Wilt.
