| Abstract/Contents: | "The efficiency of the Weedbug® system, applying glyphosate [N-(phospho-methyl)glycine] to control Parramatta grass [Sporobolus indicus (L.) R.Br. var. capensis] was investigated in a sports turf situation. Both Roundup® and Roundup® Biactive™ were applied neat (100% strength) and diluted to 80% and 75% strengths. All treatments, by rotary wick application, resulted in a high degree of kill and statistical analysis indicated no significant difference in efficacy between treatments. Roundup® 100% strength treatment had the lowest efficacy of 88.5% success. The treatment which was most effective in killing the Parramatta grass, Roundup® 75% strength, also seriously affected the host kikuyu (Pennisetum clandestinum Hochst. ex Chiov.). A rating system, when applied, indicated Roundup® Biactive™ 75% strength was far superior for use in kikuyu turf. Examination of the leaf blades by scanning electron microscopy (SEM) established normal epidermal morphology and the effect of the abrasive action of the rotating rope wick, on both the upper and lower surfaces. The underside of treated leaf blades exhibited the most effective surface abrasion and therefore greater opportunity for herbicide absorption." |
