tailieunhanh - Morphological characterization and pathogenicity of oidium Mangiferae on mango

Samples of powdery mildew of mango collected from the different areas of Himachal Pradesh revealed the absence of cleistothecia. On the basis of anamorphic characters like presence of abundant, hyaline, barrel- shaped to ellipsoid and single celled conidia produced singly or in chains of two to four, germinating conidia produced simple germ tubes, Superficial, hyaline and septate mycellium. The fungus inciting the disease was identified as Oidium mangiferae. In the pathogenicity tests during April on one year old grafted mango cv. Dusheri, symptoms appeared after 8 days and 5 hours of inoculation on leaves whereas on pedicels symptoms appeared after 10 days and 20 hours. | Morphological characterization and pathogenicity of oidium Mangiferae on mango
