PROJECT DESCRIPTION
Minimise losses associated with insecticide resistance in the green peach aphid through surveillance, preparednes and understanding implications for virus management.
PROJECT MANAGER
Ben Congdon
PROJECT OUTCOME
By 2023, grain growers and advisors are following insecticide resistance management strategies to control green peach aphids, resulting in reduced insecticide use and yield losses from Turnip Yellows Virus, and an extension to the life of effective chemical options.
PROJECT OUTPUT 1
From Jan 2020, new testing methodologies developed to rapidly & inexpensively screen for insecticide resistance to new chemicals in GPA. This will include: 1. new testing methodologies and baseline data 2. Limited sulfoxaflor resistance mechanism work.
PROJECT OUTPUT 2
From Jan 2020, national insecticide resistance surveillance and ongoing resistance testing service fro GPA made available to grain growrs and advisors. To include: 1. National surveillance and resistance maps & 2. Resistance testing service for growers.
PROJECT OUTPUT 3
From Dec 2020, research to support updates of the resistance management strategy and pest management guidelines for GPA. To include: 1. Selection experiments and 2. Impacts of resistance on effectiveness of neonicotinoid seed treatments.
PROJECT OUTPUT 4
By Dec 2023, growers will have tools by which to quantify regional and seasonal risk of GPA and TuYV. To include:
1. Investigation of non-crop virus and aphid reservoirs,
2. Local migration cues in the GPA &
3. Risk based early warning system for TuYV.
