Polygonal interaction of metal (copper)-pathogen [Macrophomina phaseolina (Tassi) Goid)]-plant (Vigna mungo L.) was investigated in Petri plate lined with sterilize filter papers provided with M. phaseolina and different concentrations of Cu(II) solution (25, 50, 75 and 100 ppm). The effect of Cu was more profound at 100 ppm however, germination and growth parameters were declined by 40-99% and by 10-50% at 25-75 ppm. Simultaneous effect of pathogen and Cu was stimulatory for V. mungo germination and growth at 25 ppm, while this effect was inhibitory at rest of the metal concentrations. The minimum tolerance was exhibited by the V. mungo seedlings incorporated with pathogen either alone or combined with 75 and 100 ppm of Cu, whereas the moderate to maximum tolerance was noticed for rest of the treatments. The study opens new vistas for the plant growers to simultaneously address biotic and abiotic issues under food security challenging in Pakistan.
