Symptoms of stemphyliosis on tomato


  • Organs attacked :


Leaves Stems


  • Symptoms :
    • Tiny brownish spots a few millimeters in diameter, slightly angular (figures 1 to 3, 5 and 6), sometimes discreetly surrounded by a chlorotic border (figure 4). Generally, they lighten gradually and eventually take on a grayish hue as they become necrotic and dry out. Damaged tissues, dull in appearance, sometimes split (figure 7).
    • Lesions extending and confluent in humid conditions to occupy large portions of the lamina, even leading to leaf mortality.
    • More or less substantial leaf fall.
    • Rare brown lesions, rather limited and longitudinal on petioles, even on stem.
