Abstract: Two field experiments were conducted at the Parma Research and Extension Center, Parma, Idaho to evaluate the efficacy of Aldicarb applied at planting or split application compared to Counter on the sugar beet cyst nematode management. The experiments were laid out in a randomized complete block design with seven treatments for the first experiment and ten treatments for the second experiment each with five replications. In the first experiment there was a significance difference in the sugar beet characters due to the application of Aldicarb treatment. Maximum beet yield and the highest beet vigor were recoded in the treatment with Aldicarb applied at the rate of 33 lbs at planting followed by Aldicarb applied as planting/post (20+13). Minimum beet yield and the lowest vigor were recorded in the plot treated with Counter. In the second experiment application of Aldicarb at planting or split application eight weeks after planting significantly increased the beet yield as compared to the untreated control. Percent yield increase (25.9%) was maximum in the treatment with Aldicarb applied at planting and post application. Lowest level of yield increase was observed in the plots treated with Counter alone while Aldicarb applied along with Counter as post application significantly increased the yield. Aldicarb performed better than Counter in terms of beet yield and percent sugar.
