Fungi are a unique group of organisms—so unique that they are put into a separate category called a 'Kingdom'. In Kingdom Fungi, some members cause rust, scab, powdery mildew, leaf spots and blights (to name but a few!).
When these fungi are ‘out of control’ many people turn to fungicides.
What are fungicides and how do they work? We have a video that explains this: https://www.youtube.com/watch?v=eNiqROUtpgo
Fungicides are used to stop fungi from attacking plants, not after you see the damage. Anyone who has grown roses knows how Japanese beetles damage plants. But do you know how powdery mildews infect and damage plants. Find out here: https://www.youtube.com/watch?v=eGwbUzPX4jE
Fungicides are best used as part of an integrated strategy that looks to improve how the plant looks or yields. Why use fungicides? Fungicides are used to protect plants when integrated management can't do the job to the degree needed to produce a harvest. Fungicides work as protectants or work systemically. This video briefly discusses the differences between the different types of fungicides https://www.youtube.com/watch?v=AVas6juNnfc
Unfortunately, most people using fungicides are less than impressed with their results. Why didn't my fungicide work? A lot of people think fungicides don't work, when in fact, they didn't use the product correctly. Learn how to properly apply fungicides for the best results.
