title: A simple flowmeter for measuring variation in the discharge rates of sprayer nozzle tips.
abstract: This communication describes a method for the rapid measurement of variations in the discharge rates of nozzle tips in the field and the percentage of increase in output. This method would facilitate the establishment of a replacement schedule for nozzle tips used in spraying programmes, and periodic adjustments when new formulations of insecticides or other types of nozzle tip are supplied.
