Abstract
A shield for use in protecting plants from environmental hazard, most particularly herbicide sprays. The shield is a two-layered structure, comprising an inner layer of a non-abrasive or resilient material secured to an outer layer of a herbicide-impermeable material. The two-layered structure is preferably a flexible composite sheet having two ends coupled together to form a circumferential barrier around the plant stem. The two ends may be coupled together with various fasteners. When a black or dark-colored inner layer is bonded to a white or light colored reflective outer layer, the temperature of the plant inside the shield may be minimized.
Claims41
