Abstract
In the early phases of plant life, Phyllactinia
dalbergiae produces powdery mildew on Dalbergia sissoo Roxb.
(shisham). The pathogen enters the host through the stomatal opening, spreads,
and establishes itself there. The first indication of a symptom is the
formation of a white, powdery mass on the leaf surface, which eventually
spreads throughout the entire stem before the plant dies. With upright
conidiophores bearing a single terminal conidium and brown-black cleistothecia
(fruiting bodies), the infected area displayed extensive mycelial development.
In a cavity slide with nutritive medium through germ tube formation, the
spore's vitality was found to be 100% within two to four days. In order to
examine the development of disease, healthy plants were infected with a 15-day-old
culture of the pathogen during pathogenicity studies. Through stomata, the
disease spreads, severely harming the tree plantation. The pathogen enters the
host through the stomatal opening, after which it spreads and becomes
established in the host. First, a white, powdery mass forms on the leaf
surface; later, it spreads throughout the entire stalk; and finally, the plant
dies.
