A new foliar disease of Koelreuteria paniculata tree is reported during continuous surveys conducted at Solan district of Himachal Pradesh during August, 2015 to December, 2015. On the basis of morphological characteristics the fungus, the fungus was identified as Phoma eupyrena which produces symptoms on the leaves as numerous small, pale, irregular spots which are light brown with dark black margins and blightening appearance at the apex region initially. Phoma eupyrena form pycnidia, whose range varied between 240-250 μm in diameter and conidia are hyaline, short, cylindrical, mostly straight and unicellular. Conidial size ranged between 3-6 × 1.5-3 μm.Keywords
Phoma eupyrena, Koelreuteria paniculata, Pycnidia.

The field experiment was conducted at experimental farm of the Department of Plant Pathology, Dr. YS. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during the period 2014-2015. Different green crop residues viz., marijuana (Cannabis sativa), mustard (Brassica rapa), peas (Pisum sativum), cabbage (Brassica oleracea), pumpkin (Cucurbita pepo), barley (Hordeum vulgare) and wheat (Triticum aestivum) were incorporated into the soil and evaluated against the Fusarium wilt, germination of bulbs and other growth parameters of the gladiolus. The soil beds amended with cabbage leaves residue showed the minimum disease incidence (11.97%) which was followed by the mustard i.e. 19.02% when compared with control (42.06%). These green crops amendment treated bed also shows increase in germination percentage, bulb number bulb weight, spike length and number of flower in spike. Beds amended with cabbage leaves residues shows highest germination of the gladiolus bulbs (92.44%), maximum number of flower in spike (14.67), longest spike (56.33) and maximum number of the bulb (15) as compare to the control. It also has better bulbs germination, plant growth, increased spike length, maximum flower in spike, increase weight and number of bulbs.Keywords
