Cedar Rust

Cedar Rust

We have received photographic evidence in our Plant Clinic email this week to show that the cedar rust galls are producing their telial spore horns and producing spores. I went to my back window to check my neighbor’s poor juniper. On Tuesday morning, I could not see any spore horns, but by Wednesday noon, I did not need the binoculars to confirm the horns are expanded. They are fully expanded due to the rain this week. All three cedar rusts (cedar-apple, cedar hawthorn and cedar quince) are active now. If you have not started protective sprays on the deciduous host, it time to get going!

SureGuard SC is compatible with non-selective herbicides like glyphosate and glufosinate (Cheetah® Pro). The patent-pending liquid formulation is easy to mix, apply and clean with no staining, no odor, or volatility concerns.
