Although spectral remote sensing techniques have been used to study many ecological variables and biotic and abiotic stresses to agricultural crops over decades, the potential use of these techniques for greenbug, Schizaphis graminum (Rondani) (Hemiptera: Aphididae) infestations and damage to wheat, Triticum aestivum L., under field conditions is unknown. Hence, this research was conducted to i...

fusarium root and foot rot of wheat is caused by the fungus gibberella zeae (fusarium graminearum). this disease causes significant yield loss under infested soil and favourable condition. the aim of this study was to evaluate the efficacy of selected fungus strains against the wheat soil-borne pathogen f. graminearum under greenhouse and field conditions. the most potent isolates were 3 isolat...

in order to evaluate of pea, bean, lentil, wheat, rape and barley sensitivity to foramsulforun, rimsulforun and nicosulforun herbicides soil residue, a pot experiment was conducted at ferdowsi university of mashhad. experimental type was completely randomized design in factorial arrangement with three replications. treatments included herbicides (rimsulforun, foramsulforun and nicosulforun), he...

abstract- the crop water stress index (cwsi) is the most common index to monitor and assess crop water stress, based on canopy temperature. to calculate cwsi, upper and lower baselines adaptable to different environments are needed. in this study, empirical and theoretical limiting baseline equations were developed to determine eggplant cwsi values at different levels of water deficit and salin...
