Is Gunner 14.3 MEC Fungicide okay to use around pets?

Yes, pets may re-enter the treated area once the spray has completely dried.

May unused spray solution be saved to apply at a later date?

No, only mix the amount needed for same-day application needs. Solutions made with propiconazole should not be stored longer than one day.

Why is is best to apply Gunner 14.3 MEC before disease development?

As with all fungicides, Gunner delivers the best protection by stopping disease before it starts. If not applied preventively, apply at the first signs of disease onset; the more progressed a disease becomes, the harder it will be to cure.

What conditions favor disease development?

Warm, humid air promotes disease development. In general, once nighttime lows are in the 60's and grass/leaves experience prolonged wetness (12 hours), disease is likely to develop and Gunner 14.3 MEC should be applied as a preventive measure.

Is it okay to rotate fungicide products from one application to the next?

Yes, in fact, rotation between different chemical classes (group #) is encouraged. When active ingredients from different classes are used in rotation, resistance development is mitigated. Artavia 2 SC is a good rotation partner with Gunner.

It Made a Difference In Managing My Lawn Fungus

I like to have a nice lawn. Sometimes the weather causes fungus problems in my lawn. I tried this Atticus Gunner fungicide and am pleased with the results. It takes a bit of time to get the fungus under control, but it's worth the wait.

Must have for home pest control control

I have used this stuff for years to do my own home pest control. Works so well. So much cheaper than buying the big box store name brand that is already mixed and works 100% better! Mixing is very easy into a tank sprayer and a little bit goes a long way. I dont notice a smell with yhis

It eliminates mosquitoes in my back yard in Mid Michigan

Using this to control the mosquitoes in my backyard here in mid Michigan. After two applications it’s doing a great job and cost me a fraction of what I used to pay someone else to do the spraying

Works but unsure if this or something else fixed it.

Got it for fungal infection in one place of my yard. Seems to have cured it. Don't know for sure.
