Fungicides 101


Fungicides can be confusing!

When you have a fungus there seem to be so many moving parts therefore it’s not as easy as killing a weed or a bug. Eliminating a fungus takes multiple applications. Often the symptoms remain visible after applying a control product making it hard to tell if it was effective or not. 

Let's help you decide which fungicide is best for your situation.




ferti•lome 2-N-1 Systemic
2-N-1 is a systemic insecticide and systemic fungicide all in one easy to use application.
Use on shrubs, flowers and ornamentals.  A single application works up to 6 weeks.

 -Available as 32oz. concentrate



ferti•lome Liquid Systemic Fungicide
This can be used for fungus in turf and can be very effective if you always make at least two applications.  You can also use Liquid Systemic on flowers, trees, shrubs, and anything not-edible
This fungicide has a side effect that acts like a growth regulator, so after you make applications you will see recovery growth. Kind of cool!  Again, use two applications, two to three weeks apart.

-Available as a concentrate and ready-to-spray





ferti•lome F- Stop Fungicide Granules
Fungus in turf is really simple........Use F-Stop Granules!  F-Stop works best as a preventative– apply before the fungus starts and you won't even get it.  If turf comes in with a fungus already started, F-Stop is also a great control choice, actually offering some recovery.  On most fungus in turf it only requires a single application.  If it is well established, you may need to make two applications 2 to 3 weeks apart.  All other fungicide granules are a minimum of two applications 2 to 3 weeks apart– but not with F-Stop!

-Available as 10lb. and 20lb. granules







ferti•lome F-Stop Liquid Fungicide
This is NOT as effective on turf as the granule and you MUST make multiple applications at 2 week intervals.  It is, however, very effective on all fruit and berry plants and recommended by many universities.
