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 : Vascular wilts (fungi and bacteria of the vessels) (Damage and symptoms on the host)

Scientific name : Verticillium dahliae

Other names : Verticillium

Highly polyphagous soil fungus infecting over two hundred species, including tomato, eggplant, potato, strawberry, cotton, sunflower, stone fruit and ornamental trees. It colonises the sap vessels, causing partial wilting, sectoral leaf yellowing and dieback of branches, with darkening of the vascular tissue. It forms microsclerotia that survive in soil for more than ten years.

Crops affected : Almond tree, Celery, Chamomile, Cotton, Eggplant, Lettuce, Peach tree, Plum tree, Potato, Strawberry, Sunflower, Tomato
