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.

Scientific name : Plum pox virus (PPV) (also Potyvirus plumpoxi)

Other names : Plum pox virus, PPV

Viral disease of stone fruit (plum, peach, apricot, nectarine) transmitted by several aphid species and by infected propagation material. It shows as chlorotic rings and spots on leaves and rings or grooves on fruit, which become misshapen, lose quality and drop early. It is the most serious viral disease of stone fruit in Europe.

Crops affected : Almond tree, Peach tree, Plum tree
