Using Drones to help measure weed infestation in vineyards

Recently, a research paper was published on the Automatic UAV-based detection of Cynodon dactylon (bermudagrass) for site-specific vineyard management. The paper was written by Francisco Manuel Jime´nez-BrenesID, Francisca Lo´pez-Granados, Jorge Torres-Sa´nchez, Jose´ Manuel Peña, Pilar Ramı´rez, Isabel Luisa Castillejo-Gonza´lez, and AnaIsabel de CastroID. This research was funded by the Spanish Ministry of Science, Innovation and Universities and EU-FEDER funds. Research of AIDC was financed by the Juan de la Cierva Incorporacio´n Program.

Bermudagrass is a weed that can pose a serious problem in vineyards. Detecting, controlling and managing this invasive weed is vital for vineyard growth and yield. In this research project, a team performed a study to see if it was feasible to create an agricultural map to quantify vineyard growth and help measure bermudagrass infestation. The research used a Microdrones UAV to capture aerial images of two vineyards using two multispectral cameras (RGB and RGNIR.)

With the help of the Microdrones UAV solution, the research team was able to conclude that it is possible to map bare soil, grapevines, and bermudagrass at the vegetative stage based on RGB- and RGNIR-imagery. These maps can be used to help farmers improve weed control in organic vineyards through a well-programmed strategy based on site-specific weed management.
