Effects of Application Time of Ethylene Dibromide and Phenamiphos on Nematodes, Southern Stem Rot, Thrips, and Yield of Peanuts
Year: 1982
Type: article
Abstract: Phenamiphos at 2.8 kg ai/ha applied at planting, and phenamiphos at 1.1 and 2.8 kg ai/ha and ethylene dibromide at 17.9 and 35.8 kg ai/ha applied postplant increased peanut yields significantly (P = 0.05) over the control. Phenamiphos at 1.1 and 2.8 kg ai/ha applied postplant to plots treated at planting with phenamiphos at 1.1 kg ai/ha increased yields significantly as did phenamiphos 2.8 kg ai/ha applied postplant to plots treated at planting with ethylene dibromide at 17.9 kg ai/ha. No treatment applied after planting increased yields in plots that had been treated at planting with phenamiphos at 2.8 kg ai/ha or ethylene dibromide at 35.8 kg ai/ha. Peanut yields were negatively correlated (P = 0.01) with root-knot indices (r = -0.47), soil populations of Meloidogyne arenaria (Neal) Chitwood larvae (r = -0.24), and southern stem rot (r = -0.33).
