What Are Lawn Pesticides and Fungicides?

Pesticides are any chemical, substance, or mixture that prevents or kills pests. “Cide” is borrowed from Latin, meaning “killer,” so insecticides and fungicides fall under the category of pesticides — as do herbicides. Our range includes insecticides, which specifically target or repel insects, and fungicides that eliminate fungal invasions in your lawn. Both of these are classified as pesticides.

What to Consider When Choosing the Best Lawn Fungicides and Pesticides

Lawn pesticides are incredibly effective, but first, you need to identify the pests causing havoc in your lawn. Once you’ve established what’s bugging your lawn or who isn’t such a fun-guy — you can move on to treatment.

Insecticides come in liquid or granular form and should be applied when it will have the most significant impact. This is usually when they’re in the grub or larvae stage. It’s an idea to use a turf mark dye indicator to let you know where you’ve applied insecticide so you don’t over-saturate your lawn with chemicals. You’ll need to consider the toxicity level of the insecticide you’re planning to use — especially if children or pets might come into contact with it. Also, be aware of the other plants in your yard. Some insecticides can harm or damage other plants you want to protect.

Lawn fungicides are usually broad spectrum, targeting many fungi species. Dead grass and yellow or brown patches indicate a fungi invasion, which most fungicides will help eliminate. We offer Headway G and Pillar SC, broad-coverage fungicides that kill a wide variety of common lawn fungi. Remember that fungicides won’t repair the damage dollar spot, or brown patch create, so you’ll need to re-seed your lawn in places where fungi have taken hold.

When and How to Apply Lawn Fungicides and Pesticides

Lawn fungicides can’t heal grass after a fungal disease but can prevent it from spreading further, or, be used as a preventative measure. As a good rule of thumb, time fungicide applications before rainfall. Wet leaves and grass are more vulnerable to fungi invasion. Therefore, during periods of heavy rain, you’ll need to increase your fungicide application to every 14-21 days.

Timing your pest control for lawn application depends on the insect species you want to kill. There are specific times in an insect’s life cycle when they’re most susceptible to the effects of insecticides. Generally, insecticide applications should take place in the fall or summer.

What happens if you use too much fungicide or insecticide?

Over-application of both fungicides and insecticides has the risk of damaging your grass and even killing it. It’s worth knowing which specific type of grass you have so you can feel reassured your chosen pesticide is safe to use on your turf.

What can I use to apply lawn fungicides and pesticides?

We recommend using a backpack sprayer for even coverage for liquid fungicides and pesticides. A broadcast spreader works well for granular formulas, which can also be used for granular lawn fertilizers and biostimulants. Although many of our products aren’t acutely toxic, reducing your skin’s exposure to any pesticide is advisable. Wearing a long sleeve shirt, long pants, and shoes with socks will ensure your skin isn’t exposed to irritants. Out of caution, we also recommend wearing protective gloves and eyewear. Ensure you remove any excess product from driveways and sidewalks and thoroughly clean your spreader after use.
