Study Name: Weed control in chickpeas

Study Number: 9909

Objectives: Evaluate chickpea tolerance to registered and experimental herbicides

Results: Only Broadstrike + Treflan caused any visible crop injury to the chickpeas. Weed infestation was very erratic, therefore we did not do individual weed ratings. Comments on weed control follow the table.

It appears that chickpeas are sufficiently tolerant to Balance and Spartan that we can pursue registration for these products. In discussions with representatives from Rhone-Poulenc, it was mentioned that they have also seen excellent chickpea tolerance to Balance. The Spartan treatments were also conducted at Carrington and Williston. There was no consistent trend in the effect of the herbicides on chickpea yield. The Frontier yield was lower due to higher kochia pressure in those plots. Disease was present in portions of the plot area.
