Abstract
The safed musli is important medicinal plant. The species Chlorophytum borivillianum contains carbohydrate (42%), protein (8.9%), root fiber (3-4%) and saponin (2-17%). Saponins are the potent medicinal compounds in the roots of safed musli. The experiment entitled “Management of Foliar and Root rot Diseases of Safed musli” was carried out during the year 2016-2017 and 2017-2018 at Nagarjun Medicinal and Aromatic Plant Garden, Dr. PDKV, Akola.
Intercropping system suppress the attack of pest and diseases as compare to monocropping. Equal or more yield of safed musli under intercropping with pigeon pea indicate that this crop do not compete with safed musli for underground resources such as nutrients and moisture and a certain degree of shade (30–40%) is helpful for the growth and root production of safed musli. The mechanisms by which intercrops affect disease dynamics include alteration of wind, rain, and vector dispersal; modification of microclimate, especially temperature and moisture; changes in host morphology and physiology and direct pathogen inhibition
The highest tuber germination 97.53 and 97.63 per cent was observed in the treatment T3 (Safed musli + pigeon pea + T. viride) at 28 days after sowing during 2016 and 2017 year respectively. The disease incidence and disease intensity increased with the rainfall and high humidity during August –October. For the management of the Foliar diseases caused by Phoma spp., Rhizoctonia bataticola, Alternaria alternata and Colletotrichum dematium and root rot diseases caused by Rhizoctonia bataticola and Fusarium solani different intercropping system and bioagents on safed musli crop were evaluated.
The lowest incidence and intensity of foliar diseases caused by Phoma spp., Rhizoctonia bataticola, Alternaria alternata and Colletotrichum dematium was observed in treatment T3 (safed musli + pigeon pea + T. viride) during both year. The highest incidence and intensity of foliar diseases was recorded in untreated control plot.The lowest incidence of root rot of bunches and roots and the highest fresh weight, dry weight per plant and row and highest saponin content per plant and per plot were observed in treatment T3 (safed musli + pigeon pea + T. viride).
Description
Present study was carried out at Nagarjun Medicinal and Aromatic Plant Garden and Department of Plant Pathology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The aim of this investigation was planned to find out management strategies against different diseases of Safed musli by intercropping system and bioagents. Intensive rapid roving survey were carried out to assess the distribution of leaf spot, leaf blight and root rot disease incidence and intensity of Safed musli at major growing areas of Vidarbha region of Maharashtra. Role of bioagents with intercropping pattern of different agronomical crop on management of foliar and root rot diseases of Safed musli were intensely studied in an in vivo condition. The data were statistically analysed.
