| Abstract/Contents: | "Research to date suggests that mowing practices following azoxystrobin application alter pest control and fate of the residue; however, efforts have not encompassed both of these aspects concurrently. Field research was initiated June 14, 2018 in Raleigh, NC to assess the effect of initial mowing timing on azoxystrobin-brown patch (Rhizoctonia spp.) efficacy and residue persistence in tall fescue (Lolium arundinaceum (Schreb.) Darbysh 'Triple Threat'). At trial initiation, azoxystrobin (0.61 kg ai ha-1) was spray applied to unique tall fescue plots and then mown (9.5-cm) at 0, 1, 2, 3, 7 or 14 days after treatment (DAT) and visually rated weekly for brown patch through 56 DAT. Concurrently, cores (92 cm2) were collected at 7, 14 and 21 DAT and then segmented into remaining aboveground vegetation and soil (0.0 to 2.5-cm depth) for subsequent residue analyses. When visually rated though 56 DAT, azoxystrobin provided excellent brown patch suppression (1.5 to 2.5%) regardless of mowing timing compared to 13% brown patch in nontreated plots. Azoxystrobin residue quantification for vegetation and soil matrices is ongoing; however, this data will provide insight into the effect of mowing timing on azoxystrobin persistence. It should be noted that clippings were not collected (i.e. treated-azoxystrobin clippings were not removed from the system) and this practice may have aided brown patch suppression regardless of initial mowing timing. Data gathered from this research may allow turfgrass managers to extend azoxystrobin residual, which could be beneficial under increased disease pressure or may result in an reduction in overall fungicidal inputs." |
