Default Quick question - Glyphosate
In NSW the general requirement for a buffer zone from agricultural use is 20M. If you are only doing spot spraying the requirement is not to contaminate the water. The main concern is detergents used as "stickers" to make the herbicide stick to leaves. If you don't use a detergent there isn't much cause for concern.
Yes. Monsanto themselves recommend painting rather than spraying. Detergents are used as spreading agents and to break down defenses.
There are different formulations of glyphosate. Some are for use in controlling weeds in streams. However, tiny amounts of glyphosate affect frogs.

Water spreads glyphosate through the soil profile. Plants such as potatoes and tomatoes are extremely susceptible.. I would think that they are now inedible other than for replanting, possibly next years crop will be good.
