Herbicide tolerance of lentil varieties - Dongara locations
Aims

To identify herbicide sensitivities of new lentil varieties with the view to reduce their yield losses due to herbicide damage.

Key messages

Lentil varieties PBA Bolt, PBA Hallmark XT and PBA Jumbo2 showed good tolerance to a range of lentil herbicides or herbicide mixtures at registered rates and timings with good crop safety margin.

Unregistered use pattern of Brodal® (diflufenican) at 200 mL/ha as PSPE and of Metribuzin 750 at 100 g/ha in mixture with Brodal® 100 mL/ha as post-emergent application reduced seed yield of PBA Bolt and PBA Jumbo2 significantly.

Note: Always follow label recommendations. The Department Primary Industries and Regional Development, does not endorse the use of herbicides above the registered rate or off-label use of herbicides or off-label tank mixes. Crop tolerance and yield responses to herbicides are strongly influenced by seasonal conditions.
