Necrotic Rusty Mottle (Lambert Mottle) and Rusty Mottle
Uncharacterized graft

Last updated
Data Coverage 3 of 6 dimensions
Cherry shows severe leaf mottle and necrosis, with buds failing to open and twigs dying, or mild rusty discoloration of older foliage. These distinct graft-transmissible viruses spread slowly in orchards. Remove diseased trees as soon as noticed. Use only virus-tested propagation material for new plantings.
Reduce moisture around affected tissue by improving drainage and air circulation. Remove rotted material cleanly and dispose of it away from the planting area. Avoid wounding healthy tissue during cleanup, as fresh wounds create new entry points. If the problem keeps returning, evaluate whether the site is too wet or poorly drained for the species you are growing.

Management
Cultural Controls
- 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.
- When a large number of trees are affected, consider orchard removal.
- Propagation material for new trees should be from certified virus-tested (and found to be free of all known viruses) bud wood only.
- References Villamor, D.E.V., and Eastwell, K.C. 2013.
- Viruses associated with rusty mottle and twisted leaf diseases of sweet cherry are distinct species.
