Morphological, pathogenic, and molecular characterization of alternaria isolates associated with alternaria late blight of pistachio.
ABSTRACT Alternaria isolates were obtained from various pistachio tissues collected in five orchards in California. For all isolates, morphological characteristics of the colony and sporulation apparatus were determined and compared with those of representative isolates of A. alternata, A. tenuissima, A. arborescens, and A. infectoria. A selection of the pistachio isolates and the representativ...
متن کاملScreening Some Medicinal Plant Extracts Against Alternaria sesami, the Causal Agent of Alternaria Leaf Spot of Sesame
Natural plant extracts / products have the potential as safe alternatives for chemical fungicides in plant disease management. Methanol and pure methanol: water (50:50 v/v) extracts of peppermint, lavandula, eucalyptus, datura and nettle were screened for their antifungal activity against Alternaria sesami, the causal agent of Alternaria leaf spot of sesame at 5, 10 and 15% concentrations in Sh...
متن کاملEvaluation of Biological Efficacy of Trichoderma Species Isolates against Alternaria Leaf Spot Disease of Sesame
Alternaria leaf spot disease is a major threat to sesame (Sesamum orientale L.) caused by Alternari asesami. Induced resistance is an alternative to systemic disease resistance response of plants. The present study aims to evaluate Trichoderma species efficacy as biocontrol via induction of resistance against A. sesami in sesame species. During in vitro bio control test, T. harzianum colonize a...
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 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...
