| Abstract/Contents: | "MON-15100 is a new experimental herbicide currently being developed for the control of annual grasses and broadleaf weeds in turfgrasses and ornamentals. Field development trials were established during late winter and spring to evaluate the effectiveness of MON-15100 formulations for the preemergence and postemergence control of crabgrass and the preemergence control of goosegrass and annual broadleaf weeds in turf. This is a summary of Monsanto Product Development trials conducted from 1986-1988 on various turfgrass species at locations in Texas and Georgia. Spring applications of MON-15100 provided a commercial level of control on crabgrass, goosegrass, oxalis, prostrate spurge, and common lespedeza in these trials. Preemergence applications provided full-season (180+ days) control of crabgrass with 0.56-0.84 kg ai/ha of the EC formulation and 0.42-56 kg ai/ha of the granular formulation of MON-15100. Higher rates of 0.56-1.12 kg ai/ha MON-15100 were required for good preemergence control for goosegrass and various annual broadleaf weeds. Early postemergence control of crabgrass was obtained with 0.56-1.12 kg ai/ha of the EC formulation when treatments were made prior to crabgrass tillering. Higher rates of 1.12-2.24 kg ai/ha MON-15100 were required for good postemergence control of crabgrass when treatments were made soon after crabgrass tillering (1-3 tillers); however, equivalent control with quicker burndown of crabgrass was provided with a tank mixture of 0.56 kg ai/ha MON-15100 and 1.12-2.24 kg ai/ha MSMA. At these rates of application, Mon-15100 demonstrated good safety on both cool and warm season turfgrass species. Results show MON-15100 to have excellent potential for sue on both cool and warm season turfgrasses for preemergence and early postemergence control of crabgrass providing a wide window of application in the spring. MON-15100 also shows good potential to provide preemergence control or suppression of many other problem weeds in turf to include goosegrass and annual broadleaf weeds. Expanded evaluation of the EC formulations in turf will be conducted under an EPA approved experimental use permit for 1989." |
