What are the key herbicide considerations when managing weeds in lentils, and how can growers protect their herbicide options for the future?

In Part 2 of the presentation from agronomist and WeedSmart Extension Officer Chris Davey, we continue the discussion on lentil weed management from the Mallee Research Updates.

While Part 1 focused on setting lentil crops up for success through rotation, crop competition and the WeedSmart Big 6, this episode takes a closer look at herbicide options, resistance and soil chemistry.

Chris explains why chemical control should be considered as part of an integrated weed management strategy, rather than the first line of defence. He discusses the importance of resistance testing, using multiple herbicide modes of action and getting the timing and application right, particularly given the limited post-emergent options available in lentils.

The conversation also explores how soil type, herbicide solubility and soil binding influence pre-emergent herbicide behaviour. Chris highlights the added challenges of sandy soils, where the margin between effective weed control and crop damage can be narrow, and explains how rainfall, deep ripping and seeding systems can influence herbicide movement and crop safety.

The episode also covers non-chemical options including weed wiping, desiccation and crop topping, harvest weed seed control, and the use of herbicide-tolerant lentil varieties.

This episode provides practical insights for growers looking to improve lentil weed control while managing resistance and protecting crop safety.

This is Part 2 of a presentation from Chris Davey. In Part 1, Chris explores soil constraints, crop rotation, crop competition and the WeedSmart Big 6.

🎧 Listen to Part 1 first, then continue with Part 2 for a deeper look at herbicide options and resistance management.
