Virtual Tillage Conference 202227 January 2022 27 January 2022
Session Two - Thursday, 27 January | 11.30am
The Virtual Tillage Conference will continue with a second session on Thursday, 27 January at 11.30am where researchers and PhD students will provide insights into current research on Pest Control Considerations and Further Research Insights. Speakers at the event include Louise McNamara, Stephen Byrne, Vijaya Bhaskar, Stephen Kildea, Elena Grosu, Diana Bucur and Jack Jameson.
Building on session one, the second session of the Tillage Conference will (i) focus on considerations for cereal disease control against the backdrop of reduced nutrient management scenarios, (ii) detail the most up-to-date outputs from the current BYDV and grassweeds surveillance initiatives and (iii) also provide attendees with a brief insight across a selection of research projects presently underway at Oak Park.
A major vector of Barley Yellow Dwarf Viruses (BYDV), aphids are the most significant pest of cereal crops in Ireland. Louise McNamara and Stephen Byrne will detail for the first time the prevalence of BYDV positive grain aphids plus the level of pyrethroid resistance in aphid populations sampled from the Teagasc suction tower network across 2020 (Carlow) and 2021 (Carlow and Cork). From the data collated to date it is clear that aphid numbers alone do not tell the full story. By combining long-term, local and long distance migratory monitoring with molecular diagnostics, the surveillance programme is enhancing our understanding of BYDV risk and spread, as well as the emergence and development of insecticide resistance.
The results of a nationwide grassweeds field survey will be presented by Vijaya Bhaskar detailing: levels of herbicide resistance in black-grass and Italian ryegrass populations; the associated underlying resistance mechanisms and implications for control methods. The status of herbicide resistance in other species like wild oats, bromes and canary grass will also be updated. Diana Bucur will outline findings on the sensitivity of Irish light leaf spot populations to key fungicides used for its control. As light leaf spot continues to be the most economically destructive disease of oilseed rape in Ireland, these findings have implications for its continued control. Elena Grosu will present early data on the potential of a novel bacterium to stimulate plant vigour. While Jack Jameson will report on the performance of crop establishment systems on Irish farms and farmer’s perceptions covering min-till, no-till and plough-based systems; both in growers own fields and in controlled experiments at Oak Park. This project includes a large study of grower’s perceptions of alternative crop establishment systems.
Session two will conclude with a focus on considerations for cereal disease control against the backdrop of reduced nutrient management scenarios. Agronomic decisions relating to disease control are critical to the success of cereal crops on farm each season. Stephen Kildea will provide an update on ongoing research underpinning these decisions, paying particular attention to the potential implications reduced nutrient management scenarios may have. He will also present an overview of how changes in disease virulence and sensitivity to critical fungicides are impacting disease control decisions and how these maybe mitigated..
Session One - Thursday, 13 January | 11.30am
Session One of the Virtual Tillage Conference takes place on Thursday, 13 January at 11.30am and focuses on Managing Crop Nutrition.
