Roundup cornfield yellows
This field had Roundup applied last July. This year the farmer planted corn, which is now about 12"- or more high. I was looking at it today and my eye was caught by a patch in a particular location. Maybe a dozen or more corn plants looked a sort of bright, light yellow. here were a few other corn plants in other areas, but not very many, maybe 2 dozen in the area I was in. There were a number of weeds of a similar colour, more weeds than corn, although there aren't a lot of weeds in total, no doubt because of the Roundup last year.
Could the yellowing of a small number of corn plants and a larger number of weeds be due to residual Roundup from last year? The yellow does not seem a natural yellow, as from excess water, for example.
Thanks for any wisdom.
