Glyphosate is an herbicide.
It is, it also could have some affect on insects.
For what it's worth, I can recall attempts to introduce panic over 'bee kills' way back in 1973.
I didn't believe any of that nonsense then either.
Yes it is but it is also called almost everywhere a pesticide as it is in the same “family” of control products and a generic name. And BTW, weeds or unwanted vegetation are pests so the appellation, pesticide, is correct again. A pest does not have to be an animal or insect.
Specific products for animal pests (deer, rabbit, etc) are also pesticides which do not kill (unless over- or mis-applicated) vegetation. Others kill insects and are labeled insecticides - which kill insect pests, but not vegetation.
Herbicides kill (or are supposed to) only vegetation which are pests as I said earlier. And so glyphosate is a pesticide and an herbicide - it just depends on the use and application.
And it interrupts the Shikimate Pathway in plants. Monsanto says that Roundup is safe for animals because the Shikimate Pathway does not exist in animals.
But it exists in most of the bacteria that live in animals. So it kills off good bacteria inside the bees, that is why there is overgrowth of other flora.
Monsanto will not be able to keep a lid on this forever...
