One-pass pre-emergence weed control is definitely possible
“We recommend and use Corvus plus atrazine, which gives us three modes of action against broadleaf weeds and grasses. Corvus is a product that we recommend because we appreciate its ability to keep fields clean early but also kick in to stop weeds that try to emerge following new rainfall.”
If there is a field where weeds happen to break through because of extreme weather, it’ll usually be spotty, and the most likely candidate for follow up to avoid using glyphosate is Laudis, contends Huffman.
Huffman reports farmers have had success using Corvus, even with challenging weather conditions this year. And Jones reports farmers in Iowa have had extremely good results with Corvus one pass, too.
“This year I think less than three percent of the Corvus acres treated at a full rate (5.6 fluid ounces per acre) plus one and a half pounds of atrazine received any post-emergence herbicide application,” Jones said.
