Public ISBD in Proceedings of the fifth National Seminar on Horticulture June 9-10, 2008 / Nepal Agricultural Research Council (NARC) (Khumaltar, Lalitpur, Nepal)     Title : Powdery Mildew and Their Non-Hazardous Control on Or~amental Plants of Kathmandu Valley Material Type: printed text Authors: Sujita Shakya, Author ; Dilli D. Shakya, Author Pagination: 104-111 p. Languages : English (eng) Keywords: A.  quisqualis,  Cinnamon  oil,  Neem  non  hazardous  ingredients, Powdery  mildews Contents note: Ornamental plants Rose, Verbena, Lagerstroemla Zinnia, Balsam, Dahlia, Reinwardtia and Chrysanthemum were found severely suffering from powdery mildew diseases. The powdery mildews diseases are caused by Sphaerotheca pannosa on Rose, Eryshiphe cichoracearum on Verbena, Zinnia and Dahlia, E. galiopsidis on Ocimum sanctum, Oidium sp. on Reinwardtia and Balsam, E. australiana on Lagerstroemia and Oidium chrysanthemii on Chrysanthemum. I Powdery mildews diseases of these ornamental plants were treated with different non hazardous ingredients spraying at the interval of ten days. This disease on Chrysanthemum was fully controlled when spraying with the mixture of Baking soda, Vinegar and Neem oil on third spray while it was controlled on rose by fourth spray. Powdery mildew on Ocimum plant was treated with the mixture of Baking soda, Vinegar and Cinnamon oil and was fully controlled on fourth spray. However, by spraying the mixture of Baking soda, Vinegar, Neem oil and leaf extract of Asuro controlled only 90% on fourth spray on Ocimum plant. Powder mildews on Verbena, Lagerstroemia, Balsam, and Reinwardtia were found to. be associated with Ampelomyces quisqualis which is known as a hyper parasite that might kill the other parasite. It is a new record for Nepal. The control of powdery mildews by the use of these non hazardous ingredients might be beneficial to the country's floriculture industry.
