How long after applying fungicide can I fertilize?

Wait 3–5 days after applying liquid fungicide before spreading fertilizer. If you have applied a granular fungicide, there is no need to wait to fertilize. Waiting between fungicide and fertilizer applications can be beneficial so you can observe the effects of each product.

When should I apply fungicide to my lawn?

We recommend beginning lawn fungicide applications when nighttime low temperatures rise to 60°F. Typically, preventative applications are made at 14 to 30 day intervals, depending upon the fungicide. There are an abundance of lawn fungicides available that prevent brown patch and other lawn diseases.

Should you water lawn before applying fungicide?

You should water your lawn before using a systemic fungicide because moist soil helps the roots absorb the chemicals. With systemic fungicide, rain is less of an issue because the rain may actually help the chemicals spread. The best time to apply systemic fungicide is after a good rain.

Does fertilizer feed fungus?

Most fertilizers contain nitrogen, which fungi love. If you feed your lawn prior to putting a fungicide down and you have a fungus, that fungus will expand exponentially. This will be disastrous for your lawn.

Can you apply granular fungicide and insecticide at the same time?

Answer: Most of the time you can apply all of those types of products together and apply them at the same time so long as all the products label of the items you are using allow tank mixing.

What happens if you put too much fungicide on your lawn?

Over-applying will damage the plants and possibly kill it. Unfortunately, fungicides cannot completely “cure” grass or plants that have already been affected by a lawn disease. However, if applied quickly enough, fungicides can stop the spread of the disease and help plants recover from disease.

Can you use too much fungicide?

All garden fungicides come with specific directions. Using too much is just as harmful as not using enough. Some people prefer to avoid the chemicals completely and opt for natural fungicides. Even when using a natural fungicide, you will still need to follow the directions carefully.

Can I apply lawn fungicide before rain?

Apply fungicides before a rain if possible. Water is necessary for most fungal spores to infect foliage and for the splash dispersal of spores. Therefore apply fungicides before a rain if it appears that the fungicide will have a chance to dry before the rain. Some fungicides list the rain fastness period on the label.

Will grass come back after fungus?

In severe cases, the fungus may affect the lower leaf sheaths, invade the crown of the grass and kill the plant. In most instances the grass will recover, but it may take two to three weeks.

Can I apply fungicide and herbicide at the same time?

Fungicides and insecticides are similar enough to be used simultaneously, says Greg Shaner, Extension plant pathologist. That cannot be said about fungicides and herbicides. Differences in application timing and spraying methods make it difficult to combine fungicides and herbicides, Shaner says.

Does fertilizer make fungus worse?

Fertilizing: Both over and under fertilizing can promote some fungal diseases. Choose organic, slow-release fertilizers for your lawn, and apply them exactly as instructed. Avoid excess nitrogen, which creates a fast green lawn with very poor defenses.

Can insecticide and fungicide be mixed together?

Tanks mixes can consist of a fungicide and an insecticide to control both a fungus and insects at the same time. Sometimes you may want to mix a pesticide with fertilizer, or mix two herbicides together to increase weed control. However, unless expressly prohibited by a pesticide’s label, mixing is legal.
