Evaluation of potassium salt of phosphonic acid in Nagpur mandarin with special reference to Phytophthora management

Phytophthora parasitica var. nicotianae is a major fungal pathogen that causes foot rot, root rot, crown rot, gummosis, leaf fall, and brown rot diseases in Nagpur mandarin in the entire Vidarbha region of Maharashtra. For the efficient management of root rot and gummosis due to Phytophthora, the po...
