Différentes disciplines scientifiques, relevant de la biologie, étudient les espèces nuisibles ou utiles aux plantes cultivées ou sauvages.
Et la phytopathologie qui consiste à diagnostiquer les maladies des plantes causées par des pathogènes (bactérie, champignons et virus). Cette discipline fait intervenir la bactériologie, la mycologie et la virologie.
The identification of weeds by agronomists is not an easy task since most of the classical methods are not adapted to that type of plant. The recent setting up of Advenrun, a software describing and helping to identify weeds in Réunion, makes it possible to avoid most of the classical flora constraints and, at the same time, to have a tool adapted to most of the users.
Read moreAll plants are not weeds. The capacity of a species to become invasive depends on a certain number of characters.
Read moreTo understand the reasons of the presence of weeds implies a deep knowledge of weediness (floristic composition, ecology and biology of species …) and the ecological and agronomical factors that influence their development. Thanks to this knowledge, it is possible to target and intervene on those factors so as to keep the weediness below the critical level of biological or economic damage.
Read more"Mauvaises herbes" or "adventices" in french , "weeds" in english are the terms one can’t get away from in weed science. But between those terms there are some subtle differences.
