Xanthomonas nasturtii was first identified as the cause of black rot watercress (Nasturtium officinale) on plants grown in Florida, USA (Vicente et al., 2017). Similar symptoms had been reported earlier Hawaii (McHugh & Constantinides, 2004) and an unidentified sp. isolated Portugal 2003 from wild (Cruz Since 2017, crops southern Spain have occasionally exhibited small yellow leaf lesions aroun...

A modern agricultural method of cultivating mustard greens and watercress with a hydroponic system in pilot greenhouse has been implemented by group farmers Cisauk-Tangerang, Banten, Indonesia. The characteristic tropical climate south the equator causes high temperatures humidity greenhouse. This study aims to control temperature using misting so that are not more than 33 °C 85%, respectively....

Abstract Microalgae and cyanobacteria could play an important role in crop protection, since they produce bioactive substances that promote plant growth and/or trigger the resistance mechanisms. The present study focuses on control of bacterial canker caused by Clavibacter michiganensis subsp. tomato plants using sonicated extracts from microalgae genera Leptolyngbya , Nostoc Chlorella Scenedes...

This paper presents results from analyzing hyperspectral BRDF data of grass lawn and watercress. The intensity of the hotspot as a function of wavelength is determined from fitting an empirical (or rather phenomenological) model to the data. The model consists of a lambertian, bowlshape, hotspot and forward scattering component. An analytical, theoretically derived relation between the hotspot ...
