Spectracide 96187 HG-96187 Insect Killer

I'm a master gardener who studied turfgrass and plant pathology in college. We were always taught that lawn fungicides could be preventive, but not curative. They needed to be applied in granular form before infection. That's an expensive pain unless you can identify the weather conditions that will lead to fungal growth and the specific areas of your lawn that will get it. Brown patch on fescue shows up almost overnight, so the conventional wisdom has always said "you snooze, you lose". This year, I snoozed, and the 6/20 photo above proves it. That mess appeared very suddenly. So I thought I'd try anything, even a product that claims to cure lawn fungus. I applied Immunox to areas of the lawn with severe brown patch when there was little wind and rain not in the forecast for 24 hours. Ten days later, the results are quite impressive, but I must add that weather conditions drastically improved in that time. We dropped into the low 80s and had rain for a week. Weather was a factor, but so was this product. This product works by inhibiting fungal growth before it kills the crowns of the plants, so it must be applied asap. I waited a week and as a result will probably have to reseed the worst spots this fall. I will apply more in 30 days, as advised by the tech rep I spoke to on the phone. Anyone who thinks this product can be used to control Japanese beetle grubs is dreaming. Those are not listed on the insects controlled and the product does not contain imidacloprid, the chemical used to kill grubs. READ THE ENTIRE LABEL BEFORE USING AND REVIEWING THIS PRODUCT, PLEASE! I did think the product packaging made it very easy to use and dispense, a nice even spray and no leakage. Makes a nice change from other hose-end spray products. I would like this made available as a fungicide only but I'm still delighted.

GREAT for killing weeds -permanently!

In a hurry and didn't read all the info. Thought I was getting fungicide only. Why would a company make a combination product like this anyway. Seems stupid.

This does a great job of getting rid of fungus and preventing it if you do it often enough

If you're impatient, expecting instant gratification with Immunox for lawn fungus, then the product won't work. I've had "rust" and "brown spot" into three growing seasons on an established lawn. I'm fairly sure my neighbor to the West is providing me with his combination of weeds (you name it) and repeat of fungus. Immunox did get rid of the "rust" and this year (2019) has started to halt the "brown spot." However, you will need to repeat the application every two weeks 3-4 times. These lawn issues are stubborn so "Massive Action = Massive Results" if your tenacious as well as patient. With all the above commentary ensure your lawn isn't suffering from something else such as grub infestation. I treat for it all using GrubEx in the Spring, in the Summer I apply Bayer Season Long Grub Control (just in case) and watch for a return of any fungus. Sad to say I fertilize using organics like Milorganite & Ringer Lawn Restore but chemical products are a necessary evil. In my neighborhood lawn care means mowing the lawn, a very few neighbors fertilize or apply "Weed & Feed" but that's it so I'm fighting all the elements. I'm sandwiched in between to residential "pastures" so I quietly over spray with "Weed B Gon" and the other items I've mentioned. It all takes time, my problems are under control but it's important to stay on top of things if you're serious about having a lush & sustainable lawn go for it. Good Luck!
