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 : Trunk and branch cankers (Damage and symptoms on the host)

Scientific name : Seiridium cardinale

Other names : Seiridium canker

Bark fungus of cypress and other Cupressaceae, introduced into the Mediterranean basin in the mid-20th century. It forms elongated cankers that ooze resin; branches above turn reddish-brown and die, sometimes killing whole trees. It spreads with rain, insects and pruning tools.

Crops affected : Conifers and nursery trees, Cypress
