Xanthomonas axonopodis punicae is the causative agent of Bacterial blight of Pomegranate that is known to cause yield loss up to 70-90%. The primary disease management method involves mainly use of chemical pesticides. In present investigation the antibacterial activity of extracts of Acacia nilotica, Datura metel, cow urine and butter milk against Xanthomonas axonopodis punicae was studied by ...

Host plant choice is of vital importance for egg laying herbivorous insects that do not exhibit brood care. Several aspects, including palatability, nutritional quality and predation risk, have been found to modulate host preference. Olfactory cues are thought to enable host location. However, experimental data on odor features that allow choosing among alternative hosts while still in flight a...

Background. To cope with their natural enemies, plants rely on resistance and tolerance as defensive strategies. Evolution of these strategies among natural population can be constrained by the absence of genetic variation or because of the antagonistic genetic correlation (trade-off) between them. Also, since plant defenses are integrated by several traits, it has been suggested that trade-off...

For the determination of the hyoscyamine-scopolamine content in small quantities of fresh plant tissue an HPLC assay was developed; with a sensitivity of about 20 ng alkaloid per run. Analysis of the different organs of Datura innoxia plants are in accord with the concept that hyoscyamine is synthesized in the roots, whereas transformation to scopolamine starts in these organs and proceeds in t...

Authenticated identification of medicinal plants always had been an issue because their local names misunderstanding and multiple morphological similarities. Hence the present study was effort to provide some authenticated taxonomic tools for three valuable selected family Solanaceae. i.e., Datura stramonium L., Solanum nigrum L. Withania somnifera This based on parameters (morphology, anatomy ...
