Understanding the role of latency in banana bunchy top virus symptom expression (BA19002)

Key research provider: The Queensland Department of Agriculture and Fisheries

What’s it all about?

Beginning in early 2020, this investment is helping the Australian banana industry better understand how banana bunchy top virus spreads and reoccurs. Previous levy-funded work through the project Banana bunchy top virus control data (BA17001) revealed that any relaxation of current bunchy top control procedures is likely to result in a significant increase in the disease, and highlighted the importance of confining the disease to its current distribution. This earlier work also identified gaps in the knowledge of how bunchy top spreads and infects banana plantations, which this subsequent project is addressing in order to improve the Australian banana industry’s banana bunchy top control program.

Key activities for this investment include:

  • Investigating possible latency (long delays in the expression of symptoms), which could explain recurrent infection on farms after long intervals
  • Assessing and improving the efficacy of current eradication practices through a better understanding of the timing of disease spread from infected plants
  • Investigating a possible role of alternative hosts of banana bunchy top virus.

Filling these knowledge gaps will assist industry in maximising the effectiveness and cost-efficiency of the bunchy top control program, which is implemented through inspection staff for the benefit of banana growers and biosecurity agencies.
