Modelling the capture of spray droplets by barley

This paper presents some of the results of a project whose aim has been to produce a fullrnsimulation model which would determine the efficacy of pesticides for use by both farmers and thernbio-chemical industry. The work presented here describes how crop architecture can be mathematicallyrnmodelled and how the mechanics of pesticide droplet capture can be simulated so that if a wind assistedrndroplet-trajectory model is assumed then droplet deposition patterns on crop surfaces can be predicted.rnThis achievement, when combined with biological response models, will then enable the efficacy of pesticidernuse to be predicted.
