Best Fungicide For Hollyhock Rust

Hollyhock rust disease, caused by the fungus Puccinia malvacearum, is a common problem in hot, humid areas where hollyhocks are grown. Hollyhock rust progresses rapidly and can quickly overwhelm your plantings if you don’t act quickly. If you want to keep your hollyhocks looking their best throughout the growing season, you will need to carefully monitor for signs of pest infestation and treat with an appropriate fungicide as soon as symptoms start to appear. Hollyhock rust is a fungal disease that can range from a minor infection, to a major problem which will destroy entire plants. Fortunately there are many fungicides that can be used on Hollyhocks to combat this disease, as well as other fungal infections. Hollyhock rust is an infectious disease that can be managed by the application of fungicides. Varieties of hollyhock that have been developed to resist rust offer options for homeowners who want to grow these flowers without resorting to a fungicide treatment. There are several different ways that you can apply a fungicide, including spraying and drenching your plants.

Best Fungicide For Hollyhock Rust


Rust is more than just a stubborn stain. It’s also a fungus that can wreak havoc on your plants, and if you leave it unchecked, you may end up with serious infestations. That’s why we’ve created this article! We’re going to share our best fungicide for hollyhock rust recommendations so you can keep your plants healthy. We’ll also talk about prevention techniques and other tips to help you deal with the problem once it starts.

Let’s Go Down The Rabbit Hole

Hollyhock rust is a fungal disease caused by Puccinia malvacearum, which spreads to the leaves and stems of your hollyhocks. It’s common in the southeast region of the United States, but it can affect Hollyhock plants anywhere.

The first sign of rust is yellowing on top leaves followed by brown spots on lower leaves as well as stems and petals. As it progresses, other parts of your plant will become affected including flowers, buds and new leaf growths which may not appear at all if they are too far-gone when they bloom (this happens frequently).

It’s important to take action before this happens because once your plant has been damaged by rust it’ll leave scars for years to come even if you manage to keep things under control from there on out!

Rust Fungus Is A Persistent Threat

Rust fungus is a persistent threat to hollyhocks. Rust fungus symptoms will appear on your hollyhock plants in the spring, summer and fall. If left untreated, rust fungus can spread from plant to plant through wind-blown spores and sap transfer.

Spraying Plants With Fungicide

Fungicides are available in several forms, including liquid, powder or granular. You can apply them directly to the leaves of your plants by spraying or sprinkling it on, but they’re especially useful for fruit trees and roses. Vegetable gardens can also benefit from a fungicide application if you have trouble keeping fungal diseases away from your crops.

Our Recommendation For Best Fungicide For Hollyhock Rust

To best control rust on hollyhocks, use a fungicide with a long residual life (one that lasts for several weeks).

Choose a systemic fungicide. This type of product penetrates the leaves and moves throughout the plant to the roots, protecting new growth from infection. It ensures an effective kill of the fungus in all parts of your hollyhock plants while also protecting them from future infections.

Select one that’s effective against rust. While most fungicides will control similar diseases such as powdery mildew and dollar spot, some are more specific than others when it comes to certain pests like rust on hollyhocks. We recommend using products manufactured by Bayer or other leading companies in this industry because they’ll contain active ingredients proven effective against this particular type of fungus—not just any random mix of chemicals that might not work as expected!

Soap and Water As A Last-Resort Option

Soap and water is a good last-resort option if you are in a rush or don’t have the right materials on hand, but it’s not necessarily effective for killing spores. If you’re dealing with a small area of rust, soap and water can help remove the visible signs of infection. However, if you’re trying to prevent any further spread of disease through spores on your plants or fence posts (as opposed to preventing new outbreaks), this method won’t be enough to keep them from infecting other susceptible hollyhocks in your yard.

How To Stop Rust Before It Starts

  • Remove infected leaves, stems and flower heads.
  • Remove infected seed pods as soon as they become visible.
  • Remove any infected seedlings before they produce new plants.

To Wrap It Up…

If you want to keep your hollyhock rust-free, the best thing you can do is use a fungicide. If you don’t have any on hand, there are other options that may work in a pinch. But prevention is always better than cure, so if you see signs of rust on your plants and notice them getting worse each week, then it’s time to spray the affected plants with a fungicide.

If all else fails (and if your plant has already been badly infected), try spraying soap and water onto the leaves to help get rid of the rust before it spreads any further. If this doesn’t work either (which isn’t likely), then it’s time to start over with new plants!

Prevention is the best cure.

If you’re not sure whether rust will be a problem in your area, consider planting hollyhocks in an area that’s further away from susceptible plants. You can also try using a fungicide to reduce the risk of rust on your new hollyhocks.

Here are some fungal diseases to watch out for:


Here’s the thing with hollyhock rust: once you’ve got it, there’s no cure. Prevention is your only option. Luckily, there are some simple things that you can do to keep it from taking hold of your plants in the first place. First off, make sure you plant hollyhocks in a sunny spot with good air circulation. If you live in an area where rust is common, don’t plant them at all! Instead try growing plants like sunflowers or petunias instead because they’re less likely to attract rust fungus spores which can sometimes travel for miles before landing on another host plant.* Secondly, keep your garden clean by removing dead leaves and flowers regularly as well as any infected ones immediately when they appear so that fungus doesn’t spread further into other parts of the yard or even into neighboring gardens via wind currents (think about how many times we’ve had strong winds recently).
