This study examined suitability...

Sensor technologies are expedient tools for precision agriculture, aiming yield protection while reducing operating costs. A portable sensor based on chlorophyll fluorescence imaging was used in greenhouse experiments to investigate the response of sugar beet and soybean cultivars application herbicides. The measured maximum quantum efficacy photosystem II (PS-II) ( F v /F m ). In beet, average 9 different 1 d after treatment desmedipham plus phenmedipham ethofumesate lenacil reduced by 56%...

Spot spraying can significantly reduce herbicide use while maintaining equal weed control efficacy as a broadcast application of herbicides. Several online spot-spraying systems have been developed, with sensors mounted on the sprayer or by recording RTK-GNSS position each crop seed. In this study, spot was realized offline based georeferenced unmanned aerial vehicle (UAV) images high spatial resolution. Studies were conducted in four maize fields Southwestern Germany 2023. A randomized...

Laboratory experiments were carried out to evaluated three diatomaceous earth (DE) formulations—Protect-It, PyriSec (at dose rates 500, 1,000, and 1,500 ppm), DEA-P 75, 150, 500 ppm)—against the larger grain borer, Prostephanus truncatus (Horn) (Coleoptera: Bostrychidae), adults in stored maize, Zea mays L., at temperatures (20, 25, 30°C) two relative humidity (RH) levels (55 75%). At these conditions, capability of progeny production treated substrate also was assessed. Adult survival high,...

The success of precision agriculture relies largely on our ability to identify how the plants’ growth limiting factors vary in time and space. In field, several stress may occur simultaneously, it is thus crucial be able key limitation, order decide upon correct contra-action, e.g., herbicide application. We performed a pot experiment, which spring wheat was exposed water shortage, nitrogen deficiency, weed competition (Sinapis alba L.) fungal infection (Blumeria graminis f. sp. tritici)...
