title: Comparison of methyl bromide and other nematicides for control of nematodes in peanut.
abstract: The efficacy of methyl bromide for control ofMeloidogyne arenaria and to increase yields of 'Florunner' peanut (Arachis hypogaea) was studied in a field at the Wiregrass Substation near Headland, Alabama. Methyl bromide was applied in the row at a depth of 35 cm using a subsoiler-bedder 2 weeks before planting at rates of 0, 34, 50, 67, 101, and 118 kg a.i./ha. Methyl bromide treatments of 67 kg a.i./ha or higher resulted in significant (P = 0.05) yield increases similar to those obtained in the same experiment with at-plant applications of aldicarb (2.2 kg a.i./ha), EDB (1.55 ml a.i./m row), or 1,3-D (5.10 ml a.i./m row). The relation between yield (Y) and methyl bromide rate (x) was described (R(2) = 0.97**) by the exponential function: Y = 2,302.963eb, where b = (- 1.901 - ln x)(2)/169.482. M. arenaria juvenile populations in soil in mid-August were too low to permit establishment of a relation between application rate of methyl bromide and size of the population.
