Rhizoctonia solani, a potentially dangerous pathogen of khasi pine and hardwoods in forest nurseries in India

Abstract

The paper describes top flaggine of Pinus kesiya and leaf web blight of 24 broad-leaved tree species caused by Rhizoctonia solani Khun anamorph of Thanatephorus cucumeris (Frank) Donk in forest nurseries in India. Damage to the foliage resulting in premature defoliation at the peak of growing season is highlighted. Infection, epidemiology and disease management are discussed.

Foliar disease infection on some forest trees

“…Harsh et al (1989) briefly reported for foliage diseases caused by 14 fungal pathogens in the nurseries of Madhya Pradesh. Mehrotra (1990) described about foliar diseases caused by R. solani in forest nurseries. Maji et al (2012), observed that mulberry varieties were affected with foliar diseases viz powdery mildew, leaf rust, Myrothecium leaf spot, and Pseudocercospora leaf spot.…”

Effect of Fungicides and Neem Oil on the Rhizoctonia Root Rot of Soybean (Glycine max L.)

“…The infection is seen in seedlings and proves to be fatal in most cases. Damping-off is the most common seedling problem caused by the fungus that leads to death of the seedlings (Mehrotra, 1990). Rhizoctonia damage may occur at any time during the growing season, but it is more severe on young seedlings.…”
