The use of pedestrian equiprnent such as sprayers, blast sprayers and fogging machines in glasshouses of dilferent size is still very common. Hand‐held sprayers or those carried by straps on the back or on one shoulder are well known. Fogging machines are in use as pedestrian or stationary equipment. For pedestrian sprayers, the quality of distribution and the accuracy ofdosing depend very much on the qualification of the operator. As to the use of stationary cold fogging, a summary is given of a research programme to investigate various influences on the quality of distribution and recovery. To guarantee reproducible results in distribution quality, the model of the cold‐fogging machine has to be adjusted to the size of the glasshouse. In big cold houses, it is important to have sufficient circulation of the airstream. The force of the circulating airstream depends on droplet size and on the size of the glasshouse. Good distribution quality and high recovery rate cannot be achieved at the same time.
