Phosphite: a novel P fertilizer for weed management and pathogen control. [PDF]

Plant Biotechnol J, 2017
Summary The availability of orthophosphate (Pi) is a key determinant of crop productivity because its accessibility to plants is poor due to its conversion to unavailable forms. Weed's competition for this essential macronutrient further reduces its bio‐availability.
