Is this the same as the pints of physan 20.?

Really don't know but maybe the label of both will give you that information?

What is ratio of product to water

Not much. A little goes a long way in Phoenix. I don't have exact amounts, but I add a capful of fungicide to my fountain every week or two. It's a small fountain, maybe 10 gallons of water or so.

Is this for lawns? If it is what will this cover

I use it in our fountain to keep the algae out. It foams white and covers the dirt and things in the bottom of the fountain. Many people have asked me if I like this and I do but not everyone might.

Excellent product to keep water in your fountain clean!

I use this product to keep my water fountain in the patio clean. Especially in hot weather in Arizona, during the summer you need to put a capful or more in the water at least once a week. I have been using this product for over 15 years and found ordering it on Amazon was the best price and fast delivery. Very happy I found it here and you will be too.

Best product for greenhouse pathogen control

I've been using this product for many years to control pathogens in several greenhouses. I don't know of any other product that effectively controls such a wide spectrum of fungi, bacteria, algae, etc. It is so concentrated that when appropriately diluted with water, a gallon jug will provide multiple years'-worth of spray and drench applications.

Buyers beware

Buyer beware! Don’t buy from this seller.The packaging is terrible. The seller shipped a heavy product in a thin box and put it in a plastic shipping bag. The product arrived damaged and leaking liquid. The seller doesn’t accept returns or refunds, so I am screwed. I don’t understand why Amazon lets this type of seller sell on their platform.
