Defoliación artificial para estimar pérdidas por daños foliares en frijol (Phaseolus vulgaris L.)
Bean diseases such as rust (Uromyces phaseoli var typica), web blight (Than:cucumeris), and angular leaf spot (Isariopsis griseola), among others, not only destroy plant foliage but also cause physiological damage. To determine yield losses, the cultivars “ICA-Guali” and "Porrillo Sintético...
