One half of a row that had been an outside untreated row ter the past two seasons was treated w:l.th liquid Simazine at 5 pounds actUal per acre on January 25. In spite of the established weeds especially alre~ emerged grass at treatment time the newly treated half'*row was weed free by late spring. . Simazine was used commercially on several large fields of' peonies. Treatments were made using granular Simazine at 4-6 pounds per acre or liquid at 3*4 pounds per acre on clean ground. In general, good peony growth and weed free ground was the result. At lower rates of Simaiine barnyard grass {Echinochoa crusgali)can be a problem. Where applications were made by growers to very wee
