Trial Information:
Chickpea fungicide trials were conducted at Minot, Carrington, and
Hettinger, North Dakota in 2003. The objectives of the trial were to
evaluate fungicide sequence and timing for the control of ascochyta blight
on six chickpea varieties that have varying degrees of ascochyta blight
tolerance. Three large kabuli varieties were used: Sierra, Dwelley, and
Yuma. The small kabuli chickpea variety, B-90 (Amit), and two desi types
were also included: Anna, and Myles.
The trial was planted May 13 into previous wheat residue at the center. The
trial design was a randomized complete block with four replicates.
Fungicides were applied with a CO2 backpack sprayer, equipped with 8002 twin jet nozzles delivering 20 gpa at
30 psi. JAU6476 is an experimental fungicide from Bayer.
