Perennial weeds survive year after year and appear to be increasing in Indiana soybean fields.
The increase of perennial weeds has been favored by trends toward less tillage and programs of control aimed at annual weeds. Na weed populations in fields scattered over the state of Indiana were used for these studies. The research for this project was completed in October 1994. Selective treatments for perennial broadleaf weeds. Directed postemergence treatments require that the crop be planted in rows, thus ting the technique for mostly solid seeded no-till soybeans.
