I immediately thought the same thing when I read the study. Most of the glyphosate applications I see are not followed by tilling, discing or other forms of “hoeing.” The R plot is conspicuously absent and it doesn't explain why that choice was made (it explains many other decisions/choices) for the study.

A lack of difference in a W and R plot would have bolstered the findings and seems an obvious thing to test?

please make this an actual feature in labs. lose the gif and have it send an auto reply to all future responses indicating I am no longer reading the email thread. in the auto-reply have a link leading to how to use bcc
