The utilizing of bioassay techniques is common for examining how allelochemicals affect plant processes. In general, at higher allelochemical concentrations, processes are impeded, whereas at lower ones, they are boosted. A mathematical model is developed to analyse this kind of reaction. It is assumed that the response of the plant organism is proportional to the allelochemical dose. This plant response is studied for delayed allelochemical dose using time delay differential equation. The feasible non-zero equilibrium point is examined and the stability analysis is studied about the equilibrium point. The system is stable if the delay in allelochemical dose does not cross a fixed critical value. However, the system exhibits limit cycles via Hopf-bifurcation when delay parameter crosses the fixed critical value. Furthermore, in the situation that the diffusion coefficient transpires. Additionally, it exists within the event exhibiting the diffusion coefficient. Analytical results are supported by MATLAB.
