Graph two depicts ten scenarios where spray released from a ground sprayer (that is, airblast and horizontal boom) will drift downwind. In all cases, a portion of the spray released from any sprayer is comprised of fine and very fine particles, and that volume fraction of spray will drift considerably farther than the rest of the spray released. The largest volume of spray that travels the furthest downwind comes from a boom sprayer emitting fine droplets more than a metre from the ground. The smallest volume of spray that travels the least distance comes from a boom sprayer one half metre from the ground emitting coarse droplets.
