Abstract
DPX-R6447 represents a new family of chemistry to be used in Florida citrus. It is a highly effective citrus herbicide characterized by low use rates. Preliminary toxicology studies indicate the herbicide has low acute oral and dermal toxicity. Citrus has demonstrated excellent tolerance to DPX-R6447 when used for preemergence weed control. Studies to date indicate no yield reductions or maturity delays have resulted from the use of this herbicide. Preemergence applications of DPX-R6447 have resulted in control of most problem weeds in Florida citrus. Key weeds controlled include narrowleaf panicum, vaseygrass, goosegrass, Spanish needles, goatweed, pigweed and balsamapple vine.
