At IR-4, we are still diligently working to ensure growers have tools to successfully manage pest problems. Our collaborating network of institutions has individually mandated or strongly encouraged employees to work from home. While many field locations are temporarily shuttered, administrative activities are continuing. We anticipate that 2020 research experiments may be compromised or delayed. Though we want to complete as much as possible, the personal safety of IR-4 team members is paramount. Once the pandemic has subsided, we will re-group and adjust. In the meantime, please reach out to the IR-4 Regional Offices and IR-4 Headquarters to answer your questions or for guidance.
