As part of his ERDC University project, Walla Walla District Biologist Damian Walter is netting Flowering-rush plants for a feeding study at the Environmental Laboratory’s greenhouse on the Vicksburg, Mississippi, campus. The plants were treated with different concentrations of jasmonic acid to trigger plant predation protection responses, followed by placement of armyworms on the plants to determine if Flowering- rush developed vegetative protection to predators.
