| Abstract/Contents: | "The commercially available plant growth retardants Embark (mefluidide) and Scotts TGR (paclobutrazole) were applied alone, as tank-mix partners and in tank-mix combinations with broadleaf weed herbicides (BLWH). The latin square design also included four crabgrass herbicides and one fungicide treatment. Five to nine replicate plots of each treatment were established within old cemetery plots averaging 1600 square feet and surrounded by fences, railings, curbing and gates. Low maintenance cemetery turf comprised mainly of fine fescues and diverse weeds was located on a southwest facing slope. Fertilizer was not used and irrigation was not available. Treatments were applied on June 4,5,6 with a 4 gallon Solo backpack sprayer delivering one third gallon dilutent per 1000 sq. ft. The area was first mown mid-May, trim mown on June 12, then remained unmown for the summer. Mowing in August was restricted to plots treated with fungicide; mowing in September was restricted to plots not receiving BLWH. The entire area received one final mowing in October. This old, seldom-visited ahd hazardous area of the cemetery suggests that methods to reduce mowing and trimming would greatly benefit both cemetery and labor force. PGRs limited fescue growth for as few as 14 weeks when used alone at label rates and as many as 16 weeks when half rates were tank-mix together. Little or no phyotoxic injury was observed, turf retained adequate color and density. Minor levels of leaf spot disease developed 3-5 weeks after treatment (WAT). Tank-mixing a combination of fungicides completely suppressed leaf spot, improved turf color and density but shortened the duration of retardation by 4 to 6 weeks. BLWs were unaffected by PGRs and continued to exert seedheads and invade areas of weak turf. The addition of BLW herbicides greatly improved over all turf quality; suppressed or controlled plantain, hawkweed, dandelion, yarrow, and sorrel but incited leaf spot and brown patch diseases in plots without fungicides. Including BLWH neither shortened nor lengthened the duration of retardation for the turfgrass species but did extend the weeks elapesd between mowings, due primarily to the prevention of weed stalks and inflorescences. Of the three BLW herbicides employed here, Confront (triclopyr+clopyralid) provided the best control of all weed species; Trimec (2,4-D+mecoprop+dicamba) provided excellent control of sorrel, dandelion and yarrow while the control of plantain and hawkweed afforded by Trimec was inadequate and by MCCP (mecoprop) was poor. Plots treated with PGR+MCPP required mowing four weeks prior to those treated with PGR+Trimec or Confront; again to remove weed seedheads. Tank-mixes of two PGRs plus BLWH provided the longest duration of retardation; PGR+Confront plots did not require mowing 18 WAT. Including preemergent crabgrass controls minimized annual grass competition, improved turfgrass quality, had no influence on disease development and did not effect the duration of retardation. Species composition shifted from Festuca sps plus weeds to a fescue/dryland bentgrass mix that included annual sedges and late germinating BLW. The percent creeping fescue declined while that of hard and sheep fescue increased, but not to the level desired. The treatments employed here were unable to effect a population shift to pure stands of fescue." |
