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 : Rots with mould (fungi and oomycetes) (Damage and symptoms on the host)

Scientific name : Monilinia spp. (M. laxa, M. fructigena, M. fructicola)

Other names : blossom blight, Monilinia rot

Brown rot is caused by fungi of the genus Monilinia that attack blossoms, shoots and fruit of stone and pome fruit trees. The fungus overwinters in mummified fruit and cankers, infects blossoms in spring during wet weather, then enters fruit through wounds. Fruit develops a brown rot with concentric rings of grey or buff spore tufts, then dries out and remains mummified on the tree.

Crops affected : Almond tree, Apple tree, Fig, Peach tree, Pear tree, Plum tree
