Factors determining the design of tractor-mounted sprayer booms—sprayer nozzle characteristics
Journal of Agricultural Engineering Research, 1978Abstract The motion of a spray boom is a major source of variation in the distribution pattern of a sprayer. The motion is evaluated in terms of the vertical motion of the boom relative to the ground and the horizontal motion of the boom relative to the tractor.

Directed Sprayer for Targeting Pesticides
Weed Technology, 1992An experimental directed sprayer has been improved for use in conservation-tillage and no-tillage field conditions and variable row widths. The directed sprayer consists of a rear-mounted toolbar with individually flotational spraying units on lightweight runners which move over field surfaces without the collection of loose residues.

A Review of Application Error for Sprayers
Transactions of the ASAE, 1992A cursory study of error quantification was conducted to develop a general error term to be applied to the performance of chemical applicators. The term developed is capable of taking into consideration the time delays associated with direct boom injection applicators.

Weed Science, 1969
A bench-mounted sprayer-flamer for research work is described. Constant rate spraying, logarithmic-dosage spraying, and flaming can be done at variable spray pressures and 10 speeds. The sprayer-flamer facilitates accurate and rapid application of material on plants and soil in pots and flats. The logarithmic-dosage sprayer gives a 16-fold variation in

Sprayer Performance Evaluation with Microcomputers
Applied Engineering in Agriculture, 1987CROP yield and quality depend very much on the effective application of pesticides. Too little chemical causes inefficient pest control while an overdose increases cost, may damage the crop, and adds to pesticide pollution problems. Traditional approaches to teaching crop producers how to calibrate their sprayers have not been very effective.
