| Abstract/Contents: | "Annual bluegrass (Poa annua L.) (ABG) is considered by many turfgrass managers to be an intractable weed problem, particularly in creeping bentgrass (Agrostis stolonifera L.) (CBG) fairways. Bispyribac-sodium (BPS) is labeled for the control of ABG, but it can elicit objectionable levels of chlorosis in CBG. Little information exists regarding the longevity of chlorosis, other potential phytotoxic effects or the ability of BPS to control ABG in CBG. The primary objectives of this field study were to determine if the chlorosis elicited by BPS could be masked by tank-mixing the herbicide with a chelated iron plus nitrogen product and to determine an effective BPS rate for controlling ABG. Bispyribac-sodium was applied to mature fairway height CBG three times at 49 and 111 g ai/ha and two or three times at 74 g ai/ha on a two-week interval. Chlorosis appeared within one week and generally persisted for 14 to 21 days, but there was no BPS rate effect on the level or longevity of the CBG chlorosis. Tank-mixing BPS with Fe + N effectively masked the chlorosis, regardless of herbicide rate. All BPS rates and timing provided similar levels (ā 82%) of ABG control." |
