Metribuzin tolerant lentils
 

Key messages

• Lentil grain yields at this site were very low and generally less than 0.5 t/ha. Seasonal conditions were very dry during autumn and winter before favourable spring growing conditions (rainfall and relatively cool maximum temperature during September and October) provided for some yield recovery.
• Despite low rainfall, all herbicide treatments damaged PBA Highland XTA (Group 2 imidazolinone tolerant) and reduced yield. Damage was exacerbated by sowing into a dry seedbed which allowed metribuzin (Group 5, trizainone herbicide) to quickly wash into the crop root zone on the break of the season.
• The grain yield of the metribuzin (and imidazolinone) tolerant variety GIA 2004 L was relatively consistent across all treatments (average 0.4 t/ha). In contrast the grain yield of PBA Highland XTA declined from 0.79 t/ha where no herbicides were applied to 0.1 to 0.2 t/ha where metribuzin was applied in crop.
• In the absence of herbicide damage, there was a large penalty for growing GIA 2004L in place of the current commercial variety PBA Highland XTA. Therefore, to replace the current variety with the metribuzin tolerant variety, growers would need to be confident that there was a high risk of herbicide damage or significant benefits to be achieved by using metribuzin at higher than current rates.
• Post-emergent applications of metribuzin are currently not on label and have only been used in this trial to demonstrate the tolerance range of GIA 2004L. Always read and follow product label thoroughly.
