Spray nozzles for grass weed control locations
Aims

To try and determine what is good practice for weed control whilst minimising the potential for drift.

Key messages

Spraying small ryegrass with translocated herbicides such as Roundup, the droplet spectrum is not as critical as what was first thought. When spraying Roundup during the time of year when drift is a problem, which occurs mainly at sowing during autumn, nozzles which produce droplets which drift less such as the Air Inducted nozzles (AI) can be used (in our trials water rates were kept at 60L/ha).
