| Other trial notes |
A new lentil variety combining clopyralid tolerance with imidazolinone is available and could improve the control of fumitory in lentils which has become a problem weed in the central mallee where lentils are grown in tight rotations. Combining the tolerance trait with new clopyralid usage practices could improve weed control options. The trial will be conducted in a location with known background population of fumitory. **The trial will also link with the product registration work lead by Gordan Cummings. *Sister trial at Kalkee |
