Pesticide type: Most pesticide labels do not advise the use of adjustable nozzles. In the past, adjustable nozzles were used for leaf applied, contact and systemic insecticides and fungicides. These nozzles are rarely used for herbicides.
Drop size/spray quality: "Fine" to "Coarse".
Risk of drift: High risk if set to emit fine spray. Low risk if set to emit coarse spray.
Spray pattern: Solid jet of liquid to circular (hollow cone) pattern. Varies by setting.
Laterally and upwards. Used less often for spraying pesticides.
Not recommended for professional spraying.
Flow rate, drop size and spray pattern vary by turning the nozzle body. A solid stream of liquid and a fine spray are all possible.
Often used on sprayers designed for the amateur gardener and the limited range of pesticides that amateur users have access to.
