Zinc Sulfate Monohydrate - 35.5% Zn - 99% Pure - 1 Pound

Killed every bit of moss on my roof the first application

Great product

Quality

This 1 lb covered the very top of the pitch of an 8 x 16 shed.

Once dissolved, this produced a lot of reddish sediment. That was probably iron. I had to filter it several times to get a clear solution.

Mixes with water well and sprays well from a hose adaptor. It killed the roof moss after one week . Much cheaper than buying a 1 quart bottle for $20 that can cover only 10 x10 meters. This bag will allow for high volume moss killing . I had used the other so-called moss killers using Fatty Acid. A waste of money and time as the moss did not die.

Excellent product

Just bought this product, I read some reviews and I feel this may jump start my Pecan trees to start production, my trees are about 17 ‘ tall and no nuts as of yet , but this spring 4/24/19 I applied it 1.5 table spoons To 1.5 gal of water sprayed it on . Time will tell 🙏

It works amazingly well to clean my driveway and roof in 2-3 days. Barely any moss on the treated side so far.

This zinc sulfate monohydrate product exceeded my expectations! With a purity of 35.5% zinc, it's exactly what I needed for my agricultural applications. The packaging was sturdy, and the product arrived promptly. The purity of 35.5% Zn ensured potent efficacy in my applications. The quantity provided great value for money. Highly recommended for anyone looking for a reliable source of zinc!

Much smaller amount then I anticipated. However.. it does seems to eliminate the moss problem, but doesn't cover much of an area. I just may not have paid enough attention to the description, and expected a little more product

Sprayed it on my asphalt ahingle roof which typically gets moss every year. Waited until the dry months to spray the roof with it after brushing off existing moss (as I usually do, and it always grows back) and making sure to soak moss areas, at least 6mo ago, mid winter now, no moss. So, I guess it works. Didn't use much, mixed with water in pump sprayer. Can't remember exactly how much, but maybe a couple tbsp per gallon is all. Quite surprised it worked so well. summer 2024 update: roof free of moss; usually grows back every winter. Nothing this year. Going to spray some more on to keep it away. Really, a couple tbsp per gallon is all that was needed. fall 2024 update: south east facing area of roof getting some moss now as the rain is back, just sprayed it again without physically removing the moss, we'll see if it dies off without physical removal this time.

Worked perfect to get rid of roof moss
