Works well & fast !!
Works. Took a day to stop patches of mold in my lawn (pythium blight) - it was spreading really fast. Had sooo much rain this spring thru mid summer. I couldn’t keep up with fighting it with a spreader loaded with regular general use fungus killer in a bag Only need 0.5oz per gallon to spray 1,000sq ft I used a 1gal hand pump sprayer & did 2 treatments about 10 days apart. Solved the problem — now I just have to re-seed patches this fall to restore lawn back to perfection The juice is expensive but you get what you pay for - it was less expensive than replacing my lawn!!

Application requires a sprayer and estimation of your rate of application
The Mefenoxam fungicide was delivered as promised. I used an ortho sprayer that has a 1 Tbs per gallon setting to spray our affected grass. The challenge then is to deliver 1-2 gallons per thousand square feet, so you have to monitor the rate at which the Mefenoxam is being used from the sprayer container and estimate the area you are covering. This is a guesstimate process. I did a second application two weeks latter as suggested. Each time I applied it before either 0.5 inches of sprinkler or rain within 24 hours. As far as I can tell it is working against the Pythium Blight, which I have only seen when there is an amount of due on the grass. I have also been bagging the clippings instead of mulching as I usually would. The grass is tall fescue that I cut at 3.5".

Great product!
Great product! Had an issue with Pythium Blight after a lawn renovation, sprayed this along with Celoxid since mefenoxim is a group 4 fungicide and Celoxid is a group 21 to help guard against disease resistance. Pretty much anything that treats blight really well has some cost to it, but better than wiping out half your yard!

It works
Bottle has lasted me all year long. It's treated my Pythium Blight that killed the yard entirely last year. I do mix this with other fungicides and spray it with a backpack sprayer.

Protect your self
I watered my trees and two days later picked up the tree that was setting in the water from two days ago and wiped my eyes and for the next week I looked like i went 10 rounds in the ring with mike tyson. After the swelling went down it left a scar under my left eye that is definitely a severe chemical burn. Product is very effective all the black spots left the trees but left a black spot on me smh.. USE PROTECTIVE MEASURES GLOVES ,EYE PROTECTION, AND LONG SLEEVES!!!!!!!!

Little goes a long way.
I would have liked the instructions to be more clear on amount to use when mixing. Hopefully I guessed correctly based on what I read. It really isn't clear, or I am just not used to this type of item. I do not know yet if it is worked, but the scent is strong and you are cautioned to wear PPE when using. Hopefully it will work on the citrus fungus that my oranges have developed. It will last a long time, if I correctly measured. Again, no idea if I measure the correct amount, but it said 7 drops for my container, so that's what I used. At this rate, I will be passing this container of chemicals down to my grandchildren, as I tiwll last a long time!
