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 : Powdery mildew (fungi) (Damage and symptoms on the host)

Scientific name : Leveillula taurica

Other names : Powdery mildew of capsicum, Powdery mildew of artichoke

Highly polyphagous powdery mildew which, unlike most powdery mildews, grows partly inside the leaf. Diffuse yellow patches appear on the upper leaf surface and a white to greyish growth underneath; affected leaves may drop. It is common in hot, dry climates on artichoke, pepper, eggplant, tomato, cotton and carrot.

Crops affected : Artichoke, Bell pepper, Carrot, Cotton, Eggplant, Tomato
