I believe you have to do some minor training and get a like certification, but yes, it comes in about a fifty percent concentrated solution with water. The LD50 of that solution is about a quart as far as I can determine.

The point of the example is that it is not acutely toxic unless you ingest a sizable amount while dealing with concentrations only available to certified farmers. The lethal amounts come up to around how much you would apply to half an acre of cropland.

Glyphosphate is also biodegradable.
