Info

Aster yellows management: controlling the ALH AYI calculated as: % leafhopper infectivity * number / 100 sweeps AY control is achieved through repetitive applications of insecticide • - Synthetic pyrethroids - currently the backbone of AY control programs ($2-4/ac) Do we have all the tools that we need to manage this disease Is there room for improvement with the current management strategies
Research and project goal Advance our basic understanding of the epidemiology of aster yellows in Wisconsin towards the development and implementation of a comprehensive management plan What additional tools can be developed Can we “modernize” previously developed tools and research
