Abstract

The efficacy of planting time applications of the fumigant 1,3-D (Telone(?) II) and the systemic nematicide aldicarb (Temik(?) 15G) for control of Meloidogyne arenaria in 'Florunner' peanut (Arachis hypogaea) was studied in a field near Headland, Alabama. Aldicarb was applied at 1.1 and 2.2 kg ai/ha in a 20 cm band with the seed furrow in the middle; 1,3-D was injected to a depth of 25 cm at rates of 17.2, 34.4, and 51.6 L/ha using 2 injectors per row set 20 cm apart with the seed furrow in the middle between the injectors. All possible combination treatments with the 2 nematicides at these rates were also studied. A treatment of 16.8 L/ha of EDB applied as described for 1,3-D was included as a standard. The experiment was conducted in the same field in 1983 and 1984. There was no interaction between the effects of aldicarb and 1,3-D on either yield or soil larval populations of M. arenaria. Aldicarb increased yield (Y) in a manner best described by Y = Ym-e where k and C are constan
