concern may be? A.increasing the genetic diversity in the weed population. B.runoff or absorption of the herbicide into local water sources. C.the use of atmospheric carbon dioxide gas for photosynthesis. D.the effect of the herbicide on pepper production in the treated plots.

Answer 1

Every true weed species is already genetically diverse - there is no evidence that I know of that shows that diversity is increasing.  That is why anyone who does weed research uses more than one population of the weed in question in their studies.  That is also one of the reasons weeds are harder to kill than domesticated plants.
