Fungicides

A fungicide is a chemical that is used to kill fungi, fungal spores, and fungal infections. In lawn care, it is primarily used as a form of plant protection for landscapes.

Fungicides control diseases caused by fungi either by inhibiting the growth of the fungus or killing the fungal pathogen. Fungicides only work specifically on fungus and cannot eliminate bacteria, nematodes, or viral diseases.

Fungicides have been part of disease management in gardens, greenhouses, and lawns for quite some time. Fungal and lawn diseases can be detrimental to the health and aesthetics of a yard or landscape and thus the use of fungicides can be a safe and affordable way to put a stop to the disease and save the infected plants.

Step 1: Identify the Fungus and Check Conditions

Specific plant types are more susceptible to some to diseases than others and researching and knowing plant disease susceptibility will help in creating a prevention schedule.

It is best to apply fungicide during the cool morning hours. If the temperature is more than 90 degrees F, wait until it is cooler to apply the fungicide.

It is important that you first know the type of fungus or disease your lawn has before proceeding with selecting a fungicide for treatment. Once the disease and/or fungus has been properly identified, you can take a look at what fungicides work best to treat your lawn.

Step 2: Mix the Fungicide

Before mixing, determine how much product you need to cover the treatment area by calculating the square footage. To do this, measure and multiply the area length times the width (length x width = square footage).

Patch Pro should be mixed at a rate between .5 to 4 ounces per 1000 square feet in a gallon of water. So for example, if you have a yard that is 2,500 square feet, you would need to mix 1.5 to 10 ounces in 2.5 gallons of water. Fill a sprayer halfway with water, add the measured amount of Patch Pro and fill the rest of the way with water. Agitate the sprayer until well-mixed and you'll be ready to apply.

If using Systemic Fungicide RTS, simply share the bottle and connect it to your hose with the plastic tab in the OFF position. Turn the water on to your hose and then push the plastic tab to the ON position to begin spraying. 

Step 3: Apply Fungicide To Infected Plants

Spray the mixture onto the grass or ornamental plants until the mixture is dripping from the blades and leaves. For best results, use a nozzle on a fan spray setting for uniform coverage.

Depending on the severity of your disease you may have to re-apply the fungicide until you do not see the presence of the fungus any longer.
