If weeds are not controlled early options for effective weed control are very limited. Ensure a low seed bank of weeds exists before electing to sow lentils. Sprays need to be applied while canopies still allow adequate spray coverage of the weed.

The use of wick wipers and crop topping has greatly helped control ryegrass to make lentils a more robust part of a rotation. Control of musk weed, vetch and medic in lentil crops still relies on pre-season seed bank management.

• Control weeds as early as possible.
• Control when weeds and the crop are at the correct growth stage.
• Do not spray when weeds or the crop are under stress.
• Check the 'rainfast' period prior to rain.
• Do not spray in windy conditions over 15 km/hr.
• Use the right nozzle output and droplet size to ensure adequate coverage.
• Ensure the sprayrig is properly cleansed of damaging residual chemicals.
• Check the withholding period for grazing and harvest.

Lentils with broadleaf weeds that need controlling.

Lentils contaminated with prickly lettuce.

Avoid vetch contamination to minimise marketability problems.
