Combined Effects of Copper and Cypermethrin on Growth and Biomass Accumulation in French Beans

The effects of copper (Cu) and cypermethrin (CPM) separately and jointly on growth performance and biomass accumulation in French beans (Phaseolus vulgaris L.) were evaluated. The tested concentration of Cu reduced number of leaves, number of nodules, roots, shoots, total plant length and biomass accumulation in different parts of tested plants significantly (p<0.05) as compared to control plants at both age of observations. However, the effect of CPM on the above parameters were insignificant (p<0.05) as compared to the control plants. The results further showed that interaction effects of Cu and CPM on tested parameters in French beans was found antagonistic in nature. Thus from present study, it can be concluded that tested CPM formulation may reduce the Cu induced toxic effects in French beans. The present study suggests that more studies are required to understand the interactive effects of Cu and CPM at biochemical and molecular levels.
