Title : Bioresources, fungicides and SAR chemicals in integrated management of Alternaria branch rot of carnation


Alternaria branch rot or leaf spot of carnation was reported as a serious disease in carnation during 2016-17 in Himachal Pradesh-India causing maximum disease severity of 26.25% in Chail  of Solan district. The symptoms on leaves initiated from the margin, tips as small purple lesions, turning grayish-brown as it matures and get blighted. Spreading later on to the stem, flower buds and even the immature flowers develops characteristic water soaked areas. Considering to the heavy losses annually and the adverse effect of the chemicals on environment, the present study was formulated with the objective to include alternative strategies in managing this devastating disease with the use of ecofriendly means. Various   bioresources and SAR chemicals were exploited to manage the disease to keep the environment clean and soil fertile. Out of the bio-products, neemazal followed by cow urine were found superior by giving cent per cent and above 95.37% inhibition at higher concentrations of 30% compared to lower conc.10, 20% .Cloves extract of garlic yielded good results in suppressing the growth of the fungus upto the extend of 60.80% .The latex of agave and fruit rind of the soapnut gave 50.60 and 47.09 per cent inhibition in mycelia growth. Maximum inhibition (91.42%) in mycelia growth was obtained with neem oil and mint oil (88.52%).Whereas in fungicides score ( difenoconazole ) and contaf ( hexaconazole) completely   inhibited the growth at all concentrations amongst the systemic fungicides which was followed by fungicide, dithane M-45 ( mancozeb) a non-systemic in nature under in vitro assessments. In field trail, the best treatments along with SAR ( systemic acquired resistant ) chemicals revealed the minimum extent of the disease severity with four applications of the sprays in score, which was followed by Contaf and combined treatments of BABA (β amino butyric acid)+ neemazal+garlic extract + neem oil and Chitosan+ neemazal+garlic extract + neem oil .The combined treatments also enhanced  all the plant growth parameters in addition to lowering of the disease level to minimum threshold. 

Audience Take Away:
• Audience will receive an overview of the disease problem of carnation crop in India
• Eco-friendly methods of the foliar disease management will be addressed which can be used by others students/
researchers /entrepreneurs for practical application under protective cultivation of flower crops
• Accurate designs for data analysis are adopted for result accuracy and problem assessing


Dr. Sunita Chandel studied her BSc Agriculture from College of Agriculture, Solan under Himachal Pradesh Krishi Vishvidhalaya, Palampur, Himachal Pradesh, India and obtained her post graduate degrees in MSc and Ph.D in Mycology & Plant Pathology in years 1987 & 1991, respectively from Dr.Y.S.Parmar University of Horticulture and Forestry, Nauni, Solan (H.P).She joined at Assistant Professor in 1992 in the Department of Plant Pathology of the same University, elevated to Associated Professor in year 2001 and to Professor in year 2009.She was awarded University Merit Fellowship in B.Sc Agriculture, ICAR Junior  Fellowship for Master’s Research, worked as Research fellow in Ph.D programme and as Research Associate before joining the University. Did her post doctorate on the topic “Biological control in horticultural crops”, under Commonwealth Academic Staff Fellowship (2005-06) programme from University of Aberdeen, Scotland, U.K. under the supervision of Steve Woodward and received SERC Fast track research proposal for Young Scientist (2001-2002)-Life Sciences of DST.
