Juniper rust

Juneberries are like any other berry – they are susceptible to infections, insect pests and bird damage.  They can be grown organically on an organic spray program, but they will suffer if you attempt a “no-spray” approach.  In fact, you can cause diseases to easily spread by letting them grow uncontrolled in a juneberry planting.

The pathogens that cause leaf spot, rust, brown rot, and powdery mildew, as well as the bacteria that causes fire blight can all infect your juneberry plantings before during, or after fruiting.  Juneberries can be damaged by Japanese beetles, chafers, root and leaf aphids, or sawfly larvae.

To help you make informed and legal choices, Cornell University has a set of pest management guidelines.  These guidelines are research-based and as accurate as we can make them.
