Vegetation type and structure can play an important role in determining the amount of spray that reaches a target as well as the amount of spray moving away from a treated area. In this paper droplet trajectory models and plant architecture models are combined using three-dimensional computer modeling techniques to develop a probabilistic model of turbulence-related spray transport around various plant architectures. The plant architecture model utilises a set of growth rules expressed in the Lindenmayer systems (L-systems) formalism linked to a C++ environmental program to determine the interception of spray droplets by the various vegetative elements. Algorithms have also been introduced to investigate the influence of droplet splash on spray deposition.(Download PDF) (Export to EndNotes)
