Objective

To determine optimum management of herbicide resistant broadleaf weeds (ALS or Group 2 resistant kochia and wild mustard) in lentil through a combination of physical, chemica,l and cultural methods. To develop an integrated weed management program that will reduce herbicide selection pressure in lentil. To determine the effect of lentil seeding rate on herbicide control of a new herbicide.

Outcome

This project provided firm evidence that producers growing extra small red lentils should increase their seeding rate to 260 plants/m2. This project determined that a full rate of Sencor is effective in controlling mustard. Results demonstrated that an integrated weed management system in lentils can provide similar weed control to a high rate of herbicide provided the seeding rate of lentils is increased. It was determined that the herbicide Cadet (fluthiacet-methyl) has greater efficacy when lentil seeding rate is increased. This project also identified that both fall Edge and spring rotary hoeing can effectively control kochia.
