Bayer Plant Science has developed a promising new RKN control product called VOTIVO. It's a seed treatment involving a soil bacteria - and sounds like it would be acceptable for organic growers as well as conventional. I don't think it's on the market yet, but earlier trials are very positive. With Methyly Bromide now illegal, it's a very exciting development for farmers.
