Control of Pratylenchus vulnus in stone fruit nurseries

Almond, peach and olive nurseries were prepared in sandy soil infested by Pratylenchus vulnus in southern Italy. Soil treatments before or at sowing included methyl bromide at the rate of 40 g/m2; 1.3 D at the rate of 15 ml/m2; dazomet at the rate of 100 g/m2 without plastic tarping, or at the rate of either 100 or 50 g/m2 with tarping, and fenamiphos Gr 5 at the rate of 100 g/m2 or 240 CS at the rate of 40 g/m2 as single application; fenamiphos Gr 10 and 240 CS were also applied at planting and two, four and six months after sowing, each time at the rate of 10 g/m2. The experiment was discontinued ten and thirteen months after sowing, respectively for olive and peach and almond. Methyl bromide, 1.3 D or fenamiphos, or dazomet, under certain circumstances, produced agronomically suitable plants, but none of the treatments eradicated the nematode.
