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 : Nematodes (All stages) Swollen or galled roots (protists, nematodes) (Damage and symptoms on the host)

Scientific name : Meloidogyne incognita

Other names : Meloidogyne

Microscopic soil roundworms of the genus Meloidogyne, of which M. incognita is one of the most widespread species in warm climates and greenhouses. Females settle inside roots and induce galls or knots that impair water and nutrient uptake. Affected plants are stunted, yellow and wilt in the heat of the day; vegetables, banana, coffee and many other crops are hosts.

Crops affected : Banana, Bean, Bell pepper, Carrot, Coffee, Cucumber, Eggplant, Lettuce, Melon, Potato, Strawberry, Tomato, Watermelon
