Contact Fungicides

A contact fungicide is a chemical compound that is used for the purpose of preventing or reducing a fungal disease from a plant.

Contact fungicides, as opposed to systemic fungicides, are not taken up into the plant tissue when applied, and protect only the plant where the fungicide has been sprayed. Contact fungicides are normally used to control foliar diseases. When sprayed, they create a protective barrier against fungal pathogens.

Contact fungicides are less costly than systemic fungicides and serve as a great preventer of fungal diseases which can commonly infect vulnerable plants. If you want to protect your precious plants from fungi, contact fungicides are the way to go.

Contact fungicides very easy to use. Simply mix (following label directions) the selected contact fungicide in a pump sprayer or hose-end sprayer and apply to your plants making sure the entire surface is coated. You then reapply periodically to keep the plant protected from the threat of fungus.

Our Recommendation

Consan 20 - Consan 20 Fungicide by Monterey is a three-in-one product—a fungicide, disinfectant, and deodorizer. It is a multi-purpose liquid concentrate that can be used indoors and outdoors to treat diseases like brown patch, black spot and algae while also being an excellent cleaning product.

Bear in mind that contact fungicides are preventative and not curative. In other words, they do not get rid of a disease. Instead, they merely prevent a disease from taking hold or protect the plant from being infected.

Step 1: Identify the Fungus and Check Conditions.

Before applying a fungicide make sure that you know the cause of the disease (is it a disease? If so what is causing it? Fungi? which one?) and when (spring, fall etc.) and how often to apply the fungicide.

By closing observing the fungus that you have experience on your plants in the past and correctly identifying the fungus and the conditions which allow it to thrive you can then better approach treatment and be pointed to the right product to use.

Step 2: Mix the Contact Fungicide

Before applying your fungicide, you will first need to determine how much you will need by calculating the square footage of the treatment area.You can calculate the square footage of your lawn by multiplying the length and width of your area together (length x width = square footage). For fungicidal purposes, dilute 2 fluid ounces of Consan 20 in 5 gallons of water. 

Step 3: Apply Contact Fungicide To Plants

Spray the contact fungicide mixture onto the grass or ornamental plants using a fan nozzle spray setting for even coverage. Spray to wet but not to the point of run-off; any fungicide that runs off the plant is wasted.

Repeated applications may be necessary to protect new growth of the plant and to replace the material that has been washed off by rain or irrigation, or degraded by environmental factors such as sunlight.
