Abstract

An L-systems based 3D canopy architecture model is created for simulating and visualising the early growth of parthenium weed in response to four environmental factors (temperature, CO2, soil moisture and plant density) and the activity of the summer rust. The outcomes provide a tool to help study the interaction between an invasive weed, a biological control agent and the environment.
