“…Increasing public concerns about pesticide use in urban environments have prompted research in alternative approaches (Hatcher & Melander 2003; Larsen, Kristoffersen & Fischer 2004). Although cultural management techniques can reduce dependency on chemical herbicides and fertilizers, they do not provide reliable broadleaf weed control (Busey 2003).…”

Summary 1.Common dandelion Taraxacum officinale is the most abundant and frequent weed within turfgrass in temperate climates. With increasing legislation banning herbicide & non-chemical means of control are needed replace phenoxy herbicides. The weediness of T. officinale is mainly the result of high seed production, dispersal and germination potential. A successful long-term weed control strategy should suppress established plants, exert negative effects on seed production and prevent seedling establishment. 2. The potential of Sclerotinia minor to cause T. officinale seed mortality and reduce seedling emergence without impact on turfgrass species was evaluated in greenhouse and field experiments. 3. A pre-emergence application of S. minor at the time of seeding and a post-emergence application at 10 days after seeding significantly reduced T. officinale emergence to 17% and 2%, respectively, compared with 70-80% germination in the untreated control. There were no adverse effects of direct S. minor contact on turfgrass seed germination, seedling emergence or seedling establishment. 4. Grass overseeding alone did not improve grass quality or reduce T. officinale population densities in a low-maintained lawn environment. When S. minor was combined with grass overseeding, at application or 10 days after application, a 70-80% reduction of the T. officinale population occurred in the first year, increasing to 95% in the following year in the absence of further treatments. Turfgrass appearance and quality significantly and continuously improved up to 80%, compared with 10-20% in the control plots. Densities of other weeds, white clover Trifolium repens and field bindweed Convolvulus arvensis , were also significantly reduced when S. minor was applied with grass overseeding compared with the bioherbicide alone. 5. Synthesis and applications . We have demonstrated that S. minor reduces seed numbers, seedlings and establishment of T. officinale and, when combined with grass overseeding, the grass sward flourishes and weed emergence and colonization are significantly reduced. Other broadleaf weeds are susceptible to S. minor and thus this bioherbicide could have utility in no-till maize, cereal grain and grass seed production systems, where producers are searching for non-chemical weed control.

“…Even though time was minimal for re‐establishment, the strategy is to get as close to 100% turf stand as possible. Larsen et al (15) made conclusions from F values, and found the highest F values were associated with ground cover before the start of a playing season.…”

Larsen et al (15) made conclusions from F values, and found the highest F values were associated with ground cover before the start of a playing season. Mowing treatments (started on 25 June 2002 and 3 July 2003, respectively) had approximately a 35-day window compared to fertilizer treatments applied at the beginning of the 70-day re-establishment window.…”

Little information exists for sports field managers on optimal ways to re‐establish trafficked areas on a sports field during a 70‐day window. A 2002 Michigan Rotational Survey reported two cultural practices sports field managers performed most consistently, regardless of maintenance level, were mowing and fertility. A study was conducted at Michigan State University in 2002 and 2003. Objectives were to (i) clarify the impact of best management practices in regards to mowing height and fertilization on re‐establishment of sports field turf during a 70‐day window, and (ii) quantify these effects during and after a 25‐day simulated traffic period. Data collected were turfgrass cover percent ratings, traction, and peak deceleration. The gradually reducing mowing height treatment was significantly higher for turfgrass cover percent ratings only at the end of the 70‐day window for both years. Fertilization, the more dominant factor, was applied at the start of the experiment (1 June) whereas mowing was not begun until four to five weeks later. Resin coated urea at 147 kg of N per ha, with a 6% Reactive Layer Coating, was most effective in providing the strongest and most uniform surface throughout the study according to playing surface measurement.

“…However, integrating control practices emphasizes the use of multiple strategies to address the causes of weed fitness, (Buhler 2002). Consequently, investigating for alternative cultural and biological practices has intensified (Hatcher and Melander 2003; Larsen et al, 2004). Biological strategies recommended alternatives to the application of chemicals that provide new environmental options weed control practices (Bailey andMupondwa 2006, Boyetchko 2005).…”

Cutting of herbicide dosage without compromising grain yield can cause to less environmental pollution and lower production costs. Field experiments were laid out over years 2012-2014 to appraise the efficacy of reduced rates of a new generation post-emergence herbicide verdict in combination with biocontrol agent to suppress three major weeds (Chenopodium album, Avena fatua and Capsella bursa-pastoris) in wheat (Triticum aestivum L.) under the condition of Non-chernozem zone, Moscow region. Below labeled rate 0.3 kg/ha-1 plus bio-agents was quite effective in suppressing total weed populations. This study revealed that a favorable level of weed reduction in wheat fields was obtained when lower herbicide rate 0.3 kg/ha-1 and bio-agents were used, that was comparable to the result which achieved for registered verdict dose as 0.5 kg/ha-1. Hence, despite the higher weed reduction efficacy was obtained with herbicide in registered label dose plus biocontrol agent, but the differences were not significant compared to below herbicide dose 0.3 kg/ha-1. Meanwhile, the best energy output (90.3 GDj/ha-1), agricultural efficiency (19.9%) and wheat grain yield 7.80 t/ha-1 were achieved when reduced herbicide rate 0.3 kg/ha-1 combined to biological agent were applied.
