Abstract
Weed control is essential for production of high quality vegetables with maximum yields. (±)-2-[4-[5-(trifluoromethyl)-2-pyridinyl]oxy]phenoxy]propanoic acid (fluazifop) is a systemic postemergence herbicide that selectively controls annual and perennial grasses in dicotylendonous crops. In the United States, fluazifop is registered for control of emerged grasses in soybeans, cotton, nonbearing trees, vines, and strawberries, dicotyledonous ornamentals, and fallow land (Imperial Chemical Industries, Inc. 1985; Fusilade-2000 product label I.C.I. Americas, Inc., Agr. Chem. Div., Wilmington, DE 19897). Research has dealt with the safe use of fluazifop in field-grown vegetables at various growth stages (4), but there are no data in the literature describing the effect of fluazifop on greenhouse grown transplants. Therefore, we determined the effect of two rates of fluazifop on the growth and development of five vegetables grown in a greenhouse for transplants.
