Conquer Fuchsia Rust Before It Strikes!

Fuchsia rust may be rare, but it's creeping into greenhouses this spring! In a recent e-Gro Alert from Cornell University's Nora Catlin, we explore how to spot and stop this threatening disease from ruining your plants.

What Is This Sneaky Fuchsia Rust?

Fuchsia rust is caused by the troublesome fungus *Pucciniastrum epilobiim*. This notorious fungus could wreak havoc on your beautiful fuchsias if left unchecked.

Identifying the Symptoms Early!

Be on the lookout for early signs of fuchsia rust! Initially, you'll notice pale, discolored leaf spots that might evolve into tan patches with purple borders. This alarming change is soon followed by "yellow-orange sporulation" on the leaf surfaces. If you notice your leaves dropping, it’s a sign that the disease has progressed, and action is vital!

Does Fuchsia Rust Spell Doom for Other Plants?

Fear not! According to Catlin, fuchsia rust is quite specific to its hosts. Apart from fuchsias, it can also infect fireweed (*Epilobium angustifolium*) and true firs (*Abies*). While it's not going on a rampage, vigilance is still essential!

Mastering Fuchsia Rust Management Techniques!

To wage war against fuchsia rust, follow these expert tips from Catlin: 1. **Bag and Banish**: Immediately bag and dispose of any infected plants and leaves. This quick action will significantly limit the spread of spores. 2. **Fungicide Fortification**: Apply fungicides designed for rust to healthy fuchsia plants. Catlin outlines several effective groups in her report, ensuring you have options to protect your greens. 3. **Prevent Future Infections**: Keep humidity low, limit leaf wetness, and ensure excellent air circulation in your greenhouse. These practices can dramatically reduce the risk of new fungal outbreaks.
