A deterministic Eulerian model of aerial pesticide application is introduced. Various assumptions allow the model to include transport of aerosol droplets with a continuous size distribution, vapour production, on-target deposition, off-target drift,

The near-wake portion of the USDA Forest Service aerial application prediction model FSCBG is applied to a sensitivity study of the length of the spray boom relative to the length of the aircraft wingspan or helicopter rotor diameter. Building on ext

Drift of the pesticide Bacillus thuringiensis Berliner var. kurstaki (Bt) was measured downwind from a gypsy moth (Lymantria dispar L.) treatment block in mountain terrain. The study was conducted in conjunction with a project to eradicate the moth a

The development of the aerial spray dispersion model FSCBG (Forest Service, Cramer, Barry and Grim) by the USDA Forest Service and the U.S. Army is reviewed. FSCBG predicts the behavior of spray material released through nozzles into the wake of a sp
