A Miniature Grid for Estimating Area of Grass Leaves 1

For control of broadleaved weeds in these species any of these hormone-type herbicides would be satisfactory with the exception of silvex on orchardgrass and red fescue. Since only the ester formulation of silvex was used whereas the other herbicides were either amines or an acid, it is possible that formulation may have been a factor. With these exceptions for Silvex, the choice of herbicide could be based on the particular weed species present and cost of herbicide. At 2 pounds per acre there would be no danger of yield loss and, depending on weeds present, there could be a worthwhile improvement in quality.
