La sclérotiniose du colza, une maladie due au champignon Sclerotinia sclerotiorum, a causé durant des années des pertes de récolte très importantes en Suisse. Toutefois, le suivi effectué par Agroscope montre que, depuis presque 20 ans, cette maladie a disparu du territoire national. Selon les récentes analyses effectuées par Agroscope, ce phénomène est sans doute lié aux modifications du climat.
