SCN, or Heterodera glycines , is the most serious disease threat to soybeans throughout the United States say researchers. Kansas farmers are no exception according to Schapaugh.
Studies show the pathogen is spreading throughout the state quicker than initially believed.
It now reaches from several eastern counties to the central area of the state as far west as Edwards County. We are going to discuss what your options are if you do have SCN infestation. SCN is a microscopic roundworm that attacks the roots of the soybean plant. The female nematode penetrates the roots causing the formation of feeding cells in the root s vascular system. As they mature, they lose their ability to move and swell into a lemon shape that eventually ruptures through the wall where they become visible on the roots.
