What is an opportunist?

An "opportunist" is a population (fungi, bacteria, insects…) that takes advantage of a favourable environment to settle in, multiply and feed on it. It often develops when the natural defences of the affected organism are weakened — for genetic reasons or linked to context (water stress, deficiencies, nutritional imbalances, overcrowding…). This is typically the case in monocultures, where a single host plant, uniform and present in large numbers, offers ideal ground for it to spread.

Identification key : Leaf spots and scabs (fungi) (Damage and symptoms on the host)

Scientific name : Zymoseptoria tritici (also Mycosphaerella graminicola)

Other names : Septoria leaf blotch

Leaf fungus of wheat, regarded as one of the main diseases of this cereal in temperate, humid regions such as western Europe. It produces elongated blotches, yellowish at first and then brown, bounded by the veins, in which tiny black dots (pycnidia) are visible. Spores are spread by rain splash from lower to upper leaves.

Crops affected : Triticale, Wheat
