| As Matt said, simazine is very safe on corn when applied as a pre-emergence product. Simazine has a longer residual that atrazine. So, depending on what your rotational crop is, you may or may not see a problem in the subsequent crop. If you are in a relatively dry environment, I would think that residual carryover would be enhanced. Do you grow corn several seasons in a row? or do you grow 1 crop of corn, then rotate to another crop? and, if rotating, which crop(s) do you tend to rotate to? |
