Potato (Solanum tuberosum) is most Nutritive Food Crop is Cultivated all Over the world the crop get affected by various pets and diseases, Among these insects, aphids, viruses bacteria and fungi are major.
The tuber rot is affected by fungi Sclerotium rolfsi causes distraction and damage of Healthy potato and get economic loss to the farmers – for the Control of the diseases different Carbon Sources were tested against Sclerotium rolfsi. Among the Corban Sources Glucose, Fructose, Maltose and Cellulose shows stimulatory effect while mannose was inhibitory effect on growth. Mannose shows reduction in growth of Sclerotium rolfsi Causes tuber rot of potato.
Potato is important food crop. It contains high in calories, rich in carbohydrates, quality protein, dietary fibers So its balance nutritive food. In Small quantities used in snacks and breakfast Preparations processed potato products such as chips and French fires and dehydrated potato for internal and Exports.
Agriculture exports as potato have significance in world economy and improve Indians National Economy. Potato is one of the leading food crops and occupies fourth position, after wheat, rice and maize crops. India is one of the major potato growing countries have rank fourth in area and sixth in production (Nayar and Varma, 1992) Quality of potato protein is comparable to milk and eggs these fox superior to those present in cereals, Pulses and Vegetables. In highly populated areas of India potato is major food supplements (Singh, 1999, Praharajetal 2006)
Potato is important part of cotton industries for sizing the clothes. Paper Industries, Production of Alcohol, Adhesive, etc. (Chaddha, 1996) In view of above properties it has been a permanent solution of 21st centuries major problems like Hunger, Malnutrition’s and unemployment (Khurana, 2006)
Various pests and diseases including Fungi affected to Potato. The tuber rot is caused by Fungi scleratium rolfsi, causes foulty handling during transportation and poor storage conditions. (Body, 1972 ; Smith at el , 1987 ; Khurana and Chandra, 1980 ; Soman, 2004 )
The attempt has been taken to carried out the control of Tuber rot by application of different carbon sources.
Materials And Methods –
The role of carbon sources was tested using potato slice method ( Solunke, 1989 ; Wakle and Kareppa, 2000) Potato slics of 75 mm diameter thickness ware prepared. The slice were dipped in 0.25% Concentration different carbon sources.
A 5 mm mycelia disc of scloretium rolfsi was inoculated aseptically on eath slice The linar growth of Scierrtium rolfsi were measured at 24 hours inteorid The plate rot inoculated tissue acts was control. The result was presented as percent control efficacy. (PCE).
The different carbon sources was used as Glucose, Fructose, Mannose, Maltose, Manito, Cellulose, Lactose, at 0.25%. The linear growth at different incubation period was measured in m.m.
The carbon sources such as Glucose, Fructose, Maltose and Cellulose Stimulate the growth of Sclerotium rolfsi, on other hand mannose was inhibitory on growth. While manitol and lactose shows reduction in growth as compared to control, as shown in table. (Singh 1973, Desai 1994 ; Solunke 1996 and Goswami Islam 1999) similar result.
