IN VITRO EVALUATION OF SOME PLANT EXTRACTS AGAINST Alternaria alternata CAUSING LEAF SPOT OF Aloe vera
Aloe Vera (L.) Burn f. is a perennial succulent plant grown worldwide mainly for medicinal and cosmetic uses. During a routine survey a leaf spot disease of Aloe vera having infected plants with large necrotic, sunken, circular to oval, dark brown spots present on both surface of leaves was observed at SHIATS and neighboring areas. Microscopical examination revealed the presence of Alternaria a...
متن کاملComparative Genomics of Pathogens Causing Brown Spot Disease of Tobacco: Alternaria longipes and Alternaria alternata
The genus Alternaria is a group of infectious/contagious pathogenic fungi that not only invade a wide range of crops but also induce severe allergic reactions in a part of the human population. In this study, two strains Alternaria longipes cx1 and Alternaria alternata cx2 were isolated from different brown spot lesions on infected tobacco leaves. Their complete genomes were sequenced, de novo ...
متن کاملEffect of Environmental Conditions on Growth of Alternaria alternata Causing Leaf Blight of Noni
Effect of different pH levels, temperature, light intensity and media were tested against the growth of A. alternata under in vitro conditions. The results of experiment indicated that the growth of A. alternata was maximum in pH range of 6.006.50 and temperature range of 25 30°C. The exposure of the fungus to alternate cycles of 12 hour light and 12 hour darkness resulted in the maximum myceli...
متن کاملFirst Record of Alternaria simsimi Causing Leaf Spot on Sesame (Sesamum indicum L.) in Korea
Leaf spot disease was observed in sesame (Sesamum indicum L.) during 2009 and 2010 in Korea. The pathogen was identified as Alternaria simsimi based on morphological and cultural characteristics. The morphological identification was well supported by phylogenetic analysis of the ribosomal DNA-internal transcribed spacer region. A. simsimi isolates caused spot symptoms on leaves and stems of ses...
متن کاملOccurrence of Alternaria alternata causing Alternaria blight in pigeonpea in India
Blight symptoms on pigeonpea were observed in alarming proportion since 2009 onwards in Andhra Pradesh state of India. Alternaria blight infected pigeonpea plants were collected from Andhra Pradesh state of India to isolate and characterize the pathogen. The isolate proved pathogenic on pigeonpea cultivar ICPL 87119. Genetic characteristics were analyzed based on the sequence of the rDNA-intern...
