Remote sensing and smart use of fertilizers to manage pests
Dr. Christian Nansen, Assistant Professor, Department of Entomology and Nematology, UC Davis
There are steadily growing concerns about how global and sustainable agricultural production and food security can be maintained in the 21st century and beyond. It is expected that arthropod pest management in agricultural systems will face profound challenges, as pesticides are being faced out, pests are developing resistance to pesticides, and because growing conditions become less predictable due to climate change and diminishing availability of water for crop irrigation. Many arthropod pest outbreaks occur in crops initially being exposed to abiotic stress, such as, drought or unbalanced fertilizer applications. In these cases, an arthropod pest outbreak may be a symptom or consequence of sub-optimal crop management regime. This presentation is about remote sensing of crop stress and how it can be used to minimize risk of pest outbreaks, as crop reflectance data provide insight into some of the mechanisms that are driving pest population dynamics, both temporally and spatially.
