Yup, propaganda.
Trace amounts of glyphosate have been found in some NZ honey. Trace amounts of glyphosate have also been found in some Ozzy honey but they accidentally forgot to mention that.
This is called negative advertising. Negative advertising is a thing, it means instead of promoting your own product, you diss the opposition product. Negative advertising has been studied as a tactic and is a bad one, because it often results in less sales of all the products. IE, in this case if the Ozzies can plant in the minds of the worlds public that NZ honey has glyphosate in it, the public perception will gradually become that all honey has glyphosate in it and buy less of the Ozzy product also.
Glyphosate is widely used because it is one of the safest herbicides. In our highly populated world we would not be able to feed everyone if we let weeds go rampant. It would be nice not to use any chemical sprays but we have to.
The fact is that glyphosate in trace amounts is in pretty much everything. There is likely more in the average slice of bread, than the teaspoon of honey you put on it.
