La sélection variétale, en matière de lutte contre les ravageurs, peut faire appel soit à des critères physiques, l'insecte étant incapable, pour des raisons morphologiques d'attaquer la plante, soit à des critères biochimiques, la présence de substances rendant la plante peu appétante voire repoussante ou peu propice à la consommation par le ravageur.

Choosing quality planting material
2017The plant quality determines success in agroforestry establishment; particularly in relation to root development. Once the farmer has selected which tree species to use it is then important to select seedlings that are best suited to the farm conditions but also ensure that the seed stock is healthy (i.e. it comes without pests or diseases).

Two sorts of plant material can be used for in vitro isolation: plants grown under controlled conditions in a greenhouse (or growth room), and those grown outside (grown in the open field). In practice, if an expiant is isolated from a plant that has been grown outside, there is a much greater chance of infection taking place.
