I realized after the Commercial Vegetable Recommendation Guide was published that there was some confusion about pyroxasulfone products for sweet corn. In the guide there is a statement that should have been deleted, it implies that one of the formulated products is safer on sweet corn than another. That is not the case. Applying Zidua, Anthem Flex, or Anthem Maxx at the same rate of pyroxasulfone (the active ingredient) will end up with the same results. Any of these products applied to sweet corn on coarse-textured soils with low organic matter is likely to cause slight stunting (less than 10%), although we have not documented any yield loss from this. We did not intend to imply that one of the formulations caused more injury than the others.
