Symptoms tomato

• Organs attacked :

• Symptoms :
  • Small, moist, dull circular lesions, light brown, progressively developing on fruit. As they extend, they become concave and their center gradually browns (figures 1 to 3)
  • Several spots can develop at the same time on the same fruit, confluent they end up covering large portions and give rise to rot.
  • The underlying flesh may be rather discolored and grainy in texture.
  • These symptoms can vary depending on the species of Colletotrichum prevalent.
• Signs : presence of dark brown to black structures in the center of the lesions, sometimes arranged concentrically: microsclerotia. (figures 1 and 4) One can also observe acervuli in which stand black bristles ( setae ). These acervuli produce, in wet periods, conspicuous salmon-colored mucous spore masses on the surface of the lesions which remain smooth and intact.
