Abstract/Contents: | "Azoxystrobin is often used to control common fungal diseases in turfgrass. Anecdotal evidence has suggested that azoxystrobin may be useful for alleviating plant-parasitic nematode damage in turfgrass. Special local need registrations in several states have resulted in increased use of Avid (2% abamectin) as a nematicide. Field trials were conducted in 2012 and 2013 to determine the effects of azoxystrobin and abamectin, applied alone and in combination, on the population densities of stubby root nematode Trichodorus obtusus. Multiple soil cores (5 cm diameter, 20 cm depth) were collected within each plot and nematodes were extracted using sugar centrifugal flotation from a 100 cm3 subsample from each core. In 2012, all treatments including azoxystrobin, reduced T. obtusus densities relative to the control. Further, the combination of azoxystrobin and abamectin as well as abamectin alone reduced T. obtusus levels comparably to oxamyl. However, in 2013 azoxystrobin significantly increased T. obtusus populations. During the second year, the only treatment that significantly reduced T. obtusus population densities was an experimental formulation of abamectin applied alone. More work is needed to fully understand the effects of azoxystrobin on T. obtusus population densities on zoysiagrass." |
