454 - seq Fusarium wilt of banana: a brief history
! 1876: First report : Queensland. 1874 Silk banana (Bancroft, 1876) ! 1880 : Spreading to the many producing regions in the world
! 1950 -: Few regions remained free of the disease ! 1900-1960 : > 100 000 ha in Central America were destroyed
! 1950 -: Banana companies were forced to change Gros Michel by Cavendish varieties ("resistant")
! 1970 : Damage reported in Cavendish in the subtropics (subtropical race 4)
! 1990 : Damage was reported in Cavendish in the tropics (tropical race 4) The disease ©!Miguel!Dita! Fusarium!wilt!of!banana! External symptoms External
