Abstract

Field experiments were conducted in which 1,3-D was applied at broadcast rates of 56 and 112 litres/ha during late winter and spring to 2 differing soil types in north Florida. No advantage was demonstrated in applying the fumigant at the higher rate for the management of Meloidogyne arenaria on peanut, and there was no disadvantage to applying a standard rate of the fumigant during winter as opposed to the standard practice of a 2-week preplant treatment. At one side, where rainfall was less than adequate for normal peanut yields, all treatments with 1,3-D decreased nematode populations and increased yields 2.5-fold over banded applications of aldicarb (broadcast rates of 6.7 kg/ha at planting with 3.4 kg/ha at peg initiation), and 5-fold over the untreated control. At a site where weather conditions were optimal and soil infestation levels of M. arenaria juveniles were relatively low at harvest, none of the treatments produced peanut yields different from the untreated control
