Abstract:
Early blight of Tomato caused by Alternaria solani is most serious and destructive disease worldwide. Different plants extracts viz. Lemon grass (Cymbopogon citratus), Giloy (Tinospora cordifoila), Papaya (Carica papaya), Madar (Calotropis gigantean) and Mix. (Cymbopogon citratus, Carica papaya, Tagetes sp.) were evaluated for mycelial growth inhibition of Alternaria solani. Two concentration viz. 10% and 15% of each plant extract was tested by poison food technique. All the tested extracts were significantly inhibited the mycelial growth of pathogen when compared with control. The mixture of plants extract (66.67%) and Tinospora cordifolia (57.44%) were significantly superior over other treatments followed by carica papaya (55.55%), Cymobopogen citratus (48.55%). Least mycelia inhibition was observed in Calotropis gigantean (46.66%). Presently many farmers are using chemicals for control of early blight of tomato however, they cause health hazards. Therefore, this investigation will be helpful to the farmers for selection of suitable plants extract, used as control of early blight of tomato.
