PMN Launches Tospovirus ‘Hub’

The Plant Management Network is proud to announce the launch of its first ‘hub’, or sitelet containing centrally focused information on specific topic areas. This new resource, which covers Tomato Spotted Wilt Virus (TSWV), is in its first phase of development, currently featuring websites, articles, and webcasts related to TSWV. In its second phase, the hub will host decision support tools to help growers and consultants manage TSWV on multiple crops. The hub’s development was supported by a USDA-AFRI grant-funded project aimed at limiting crop losses due to thrips-transmitted tospoviruses. View the new tospovirus hub
