To compare different rates of trifluralin incorporated by seeding on oats in the Wickepin region and its effects on weed control, germination, yield and grain quality.
This trial has now been conducted over four seasons (2017-2020). The results from the 2020 trial support the findings of previous years, with no relationship between trifluralin application rate and oat or ryegrass plant numbers being recorded. Ryegrass counts throughout this trial have not decreased when Trifluralin rates have increased. Based on the results, increasing trifluralin rates above label recommendations has not impacted the grain yield of oat crops.
