1. Southern Ag – Liquid Copper Fungicide

  • Southern Ag – Liquid Copper Fungicide

How should I store it? Store in a cool dry place out of direct sun and before opening, shake well for 5 minutes to ensure proper mixing of ingredients.

How should I dispose of it? Do not contaminate water sources or food by storage or disposal. Dispose of empty container in accordance with local regulations.

2. Spectracide Immunox

Zoysia grass is a type of turf grass that grows well in sunny, warm climates. It thrives in soils with high pH levels and is commonly used as a ground cover for patios and walkways. Unfortunately, it’s also prone to disease. Brown patch (Rhizoctonia solani) can cause browning patches on the leaves of your zoysia grass, which will eventually turn yellowish-green or tan before dying off completely.

To eliminate brown patch, you’ll need to treat your entire lawn with fungicide; this will prevent new growth from developing. You’ll also want to avoid overhead watering so you don’t reinfect your zoysia grass after you’ve treated it with fungicide

3. Daconil Action

Daconil Action is a broad-spectrum fungicide that is effective against many different types of turfgrass diseases. It’s a water-based fungicide that offers good control of several common brown patch pathogens.

Daconil Action is labeled to control:

Brown Patch (Rhizoctonia solani)

Pythium Root Rot (Pythium spp.)

Early Spring Fungus (Albugo spp.)

4. Fertilome Broad Spectrum Landscape and Garden Fungicide

Fertilome Broad Spectrum Landscape and Garden Fungicide contains a mix of two active ingredients known as chlorothalonil and mancozeb. These help to kill brown patch fungus in zoysia grass by preventing it from feeding on your lawn. It’s important to follow the instructions on the label when applying this product so that you can get the best results possible.

The first step is to spread out 1 pound per 1000 square feet of lawn with a hand spreader or lawn roller if you have one (a rotary or drop spreader will work too). You should also make sure you’re not wearing any clothing that could come into contact with the fungicide, as it can cause skin irritation or burns if it comes into contact with your skin while still wet.

Next up is watering down your new application within 24 hours of application, although this may vary depending on how much rain falls during this time period as well as how recently it rained before applying fertilizer; check with your local cooperative extension service for more information about how often and how much water should be applied after fertilizing grasses such as zoysia grass. It’s also important not only apply enough water but also make sure that all areas receive proper irrigation so there aren’t any dry spots left over from previous applications! If necessary repeat these steps every six weeks until symptoms disappear completely from all infected areas before planting new seedlings back into those areas again; similarly wait about six months before reseeding any damaged areas after treating them appropriately first (see below).

5. Bayer Advanced

Bayer Advanced is a fungicide that has been proven to be effective against brown patch. It is a systemic fungicide, meaning it can be applied either as granules or liquid and will work its way through the plant systems to help prevent infection. Bayer Advanced also works on a variety of turf-specific diseases like dollar spot, Pythium blight and damping off. It does have some limitations: You should not apply it to your zoysia grass if there’s excessive rain expected within three days of application because water will wash away the chemical’s residual effect before it has time to completely dry in the soil.
