Try this out for math.

How many pounds of active-ingrediant Fipronil is in a 50 bag of Top Choice?

The reason is that I am trying to educate people about how much chemical is on their yard compared to what the vet gives out when he gives them Front Line for their dog or cat.

I have already tried to look for it on the lable and I can't find it.

I will try.
In a hundred pound bag at .0143 percent, you would have .0143 pound.

In a 50 pound bag, you would have half that, or .00715 pound.

That is around a tenth of an ounce.

I would say about a half teaspoon.

The label I see is 00.0143%...

That would mean 50lbs x 16 oz/lb = 800 oz

800 oz X .000143 = .1143 oz... just over a tenth of an ounce in a 50lb bag.
