Objectives What's New

Promote the national network of onion and other allium researchers, extension personnel and industry reps in relation to the following objectives:

  •  Screen onion germplasm for improved levels of  tolerance to Iris yellow spot virus and thrips

  •  Develop onion production systems that consider the interaction of multiple pests, plant stresses, and production practices;

  • Identify onion responses to varying levels of thrips and Iris yellow spot virus infection; and identify cultural and biological tactics that can reduce or replace insecticides for thrips and Iris yellow spot management.

  • Biology and epidemiology of Iris yellow spot virus;

  •  Information transfer of progress dealing with IYSV and thrips biology and IPM strategies to the onion industry and other interested parties.
