Project: Role of orchard hygiene in the potential reduction of fungicide use for control of apple scab (Venturia inaequalis)

 

Project Leader(s):

Dr Sean Mac An tSaoir

Project Objectives

To evaluate the role of leaf litter in the over wintering of Venturia inaequalis and to develop strategies to reduce disease pressures in the spring

Project: Evaluation of 'Smart Fresh' (1-MCP) as a growth regulator for enhancing the quality of Bramley apples in long term storage

 

 

 

Project Leader(s):

Dr Sean Mac An tSaoir

Project Objectives

The production of safe food, from a pristine environment whilst supporting the rural economy is central to DARD's mission statement. The overall objectives in this project are to evaluate a new plant growth regulator for efficacy on Bramley apples under long term storage regimes - maintaining quality and preventing scald (a serious bramley storage disorder). The elimination of metylaxyl apple drenches (with associated fungicides) will improve the health and wellfare of the rural community, reduce pesticide disposal problems, and potentially increase income. Use of 1-MCP eliminates the use of fungicides (to prevent storage diseases) and the second objective will be to develop a pre-harvest disease control strategy to ensure clean fruit prior to storage.

Project: Evaluation of Armagh Orchard Trust Apple Gene Bank for potential cultivars suitable of organic apple production in Northern Ireland (I. Establishment Phase)

Project Leader(s):

Dr Sean Mac An tSaoir

Project Objectives

There are two major objectives:

  •  to set up a replicated field trial of the genebank material on an organically registered site and evaluate the establishment of the cultivars under organic conditions as specified by the Soil Association.

 

  • to fingerprint the collection using microsatellite technology already available within the Science Service. The collection is based on locally named cultivars and there is the risk of different names on the same tree. In addition, because the collected trees had local value, there may be common genetic backgrounds amongst them which would be important in developing future strategies for organic production systems.
  • To review all relevant organic apple trials for commercial cultivars suitable for growing organically under Northern Ireland conditions.

Project: Evaluation of tunnel spraying on Bramley trees grown in a hedge system for potential reduction of agrochemicals

 

 

 

Project Leader(s):

Dr Sean Mac An tSaoir

Project Objectives

  • to determine true savings in agrochemical usage from a tunnel sprayer in comparison with a conventional air assisted blow sprayer.
  • to develop a new form of hedge system for growing Bramley trees so that they are amenable for tunnel spraying.
