Symptoms on Chilli

• Organs attacked :

• Symptoms :
  • Initially small circular to elongated chlorotic lesions (Figure 1).
  • Subsequently, the spots expand, turn brown, and gradually become necrotic (figure 2). A reddish-brown border encircles them. their diameter can be more than 1 cm.
  • The center of the spots lightens gradually taking on a gray to whitish tint, and sometimes presents concentric patterns giving them a so-called "frog eye" appearance. A yellow halo is sometimes visible (Figure 3).
  • Similar but elongated lesions are sometimes visible on the petioles (Figure 4) and the stem.
  • Degraded fabrics dry out, split and eventually fall off; the leaf blade is thus partially riddled.
  • Severely affected leaves turn yellow, wither, and may drop.

• Signs : Fruiting bodies of the fungus dot the lesions, sometimes giving them a slightly light gray tint. Under the light microscope, many conidiophores can be observed carrying hyaline, elongated and septate conidia.
• Possible confusion : rare
