What is Brown Rot

Brown rot is a destructive disease of citrus fruits. The fungus overwinters in mummified fruit which has either fallen to the ground or is still attached to the tree. Cankers on stems and spurs are another source of disease spores. At blossom time the fruiting bodies of the fungus develops toadstool-like structures which shed millions of spores. These spores will shed at the slightest disturbance.
