Data Coverage 3 of 6 dimensions
Cherry leaves develop angular purplish-brown spots about a month after bloom from a graft-transmissible viral agent. Symptoms appear erratically depending on climate. Use only certified virus-free stock for grafting. Remove and destroy infected trees if desired; management is usually unnecessary.
Removing trees with necrotic rusty mottle as soon as noticed has significantly reduced the disease's spread. Removal of diseased trees with rusty mottle when they are infected to the point they no longer can produce profitable crops.
