Maize applications

In the maize crop, timely application gives the optimum coverage of weeds. The potential for spray coverage problems increases as height differential between the target and crop canopy increases. With increasing height and size of the crop, an increasing percentage of the applied herbicide dose is intercepted, whilst the targeted weeds receive a reduced dose. Raising the boom height further does little to alleviate problems with coverage but increases the potential for herbicide drift.

Pre-emergence herbicides application

Water volume	100 l/ha (70-80 l/ha for Airtec)
Nozzle choice	1st choice: Hawk Nozzle angled forward and back along the boom 2nd choice: Syngenta Potato Nozzle angled forward and back along the boom
Application speed	12 km/h
Other comments	The Hawk nozzle and the Syngenta Potato Nozzle should be operated at 2 Bar pressure, for the best compromise of coverage with minimal drift. Boom height should be no higher than 50cm above the crop.

Post-emergence herbicide application

Water volume	200 l/ha (70-80 l/ha for Airtec)
Nozzle choice	1st choice: Hawk Nozzle angled forward and back along the boom 2nd choice: VP Flat Fan
Application speed	12 km/h (reduce to 8 km/h if weeds sheltered by thick crop)
Other comments	The Hawk nozzle and the Syngenta Potato Nozzle should be operated at 2 Bar pressure, for the best compromise of coverage with minimal drift. Boom height should be no higher than 50cm above the crop.
