Target Spot
Tomato

The disease starts on the older leaves and spreads upwards. The first signs are irregular-shaped spots (less than 1 mm) with a yellow margin (Photo 1). Some of the spots enlarge up to 10 mm and show characteristics rings, hence the name of 'target spot' (larger spots Photos 1&2). Spread to all leaflets and to other leaves is rapid , causing the leaves to turn yellow, collapse and die. Spots also occur on the stems. They are long and thin. Small light brown spots with dark margins may also occur on the fruit.
