Abstract
The common bean plants "Phaseolus vulgaris L." is frequently attacked by the two spotted spider mite (TSSM) Tetranychus urticae, causing a several decrease in bean plant growth and yield. Therefore, for commercial production of bean in the field, controlling mite infestation is necessary. Foliar application of salicylic acid (SA) or methyl jasmonate (MeJA) on common bean plants before or after two spotted spider mite infestation proved to be effective in reducing infestations. In most concentrations these elicitors significantly improved common bean plant growth i.e. had a positive effect on plant height, number of branches, shoot dry weight and leaf area per plant and bean yield. SA at 100 mg/L had the strongest positive effect. Moreover, application of elicitors significantly altered leaflet anatomical characters i.e. increased thickness of leaflet blade, thickness of palisade and spongy parenchyma as well as thickness of midrib region of the leaflet and changed the dimension of vascular bundles, resulting in mite infestation had strongly decreased on these leaflets of new anatomical characters. We conclude that both elicitors, in particular, 100 mg/L SA could be used for controlling T. urticae infestation, to improve plant growth and to improve bean yield and its quality in the field.
