Aims

To investigate optimum safe trifluralin rates and water rates in wheat on canola stubble.

Key messages

A thorough understanding of trifluralin application techniques can be the difference between poor and excellent ryegrass control. It can also help achieve target plant establishment. This demonstration showed an increase in ryegrass control when up to 3L/ha trifluralin was applied. Rates above 3L/ha trifluralin did not result in additional ryegrass control. The influence of water rates was minimal due to the lack of stubble residue which shows that water rates of 50L/ha are acceptable in situations where there is very little residue from the previous crop.
