Evaluation 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 کاملInvestigation of Winter Survival of Safflower Genotypes in Isfahan-Iran
Too often crop production is facing with different intensity of cold damage. In some years the damage is severe and has a large social and economic consequence. Therefore, selection and introduction of cold tolerant cultivars is very effective in reducing cold damage and increasing crop production. Frequently, in winter safflower yield trails in Isfahan province, depending on the intensity of w...
متن کاملEvaluation of Oil Content and Fatty Acid Composition in Seeds of Different Genotypes of Safflower
Evaluation of four safflower (Carthamus tinctorius L.) genotypes for oil content and fatty acidcomposition showed that oil content varied from 22.16 to 34.39% and the highest seed oilcontent was obtained from Isfahan14 genotype (34.39%, respectively). Among those fatty acidswere detected, linoleic acid (75.81- 77.86%) was the predominant fatty acid followed by oleic(12.57–13.75%), palmitic (6.0...
متن کاملAzadirachta indica leaf extract induces resistance in sesame against Alternaria leaf spot disease
Induced resistance is an important component of disease-resistance response of plants, and is accompanied by increased capability for activating defense responses upon pathogen ingress or elicitor treatment. Aqueous leaf extract of neem (Azadirachta indica Juss.) provided the control of Alternaria leaf spot pathogen (Alternaria sesami) of sesame (Sesamum indicum L: Syn. S. orientale L). Treatme...
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...
