6.3.1 Hydraulic nozzles
The volume of water used per hectare (volume application rate) directly affects the amount of pesticide applied, and is dependent on the nozzle used, together with the operating pressure.
The latter also affects the spray angle and spray quality, which in turn affect the effectiveness of spray application (efficiency of dose transfer to the target pest).
The most common spray nozzles, and the pattern of spray produced, are as follows:
The right combination of disc and core nozzle (e.g. D1.5-25) can be pre-fixed to maximise the spray deposited on pods and branches.
