Resurgence of Soilborne Pests in Doublecropped Cucumber after Application of Methyl Bromide Chemical Alternatives and Solarization in Tomato

Abstract: Field studies were conducted during four consecutive tomato ( Lycopersicon esculentum ) -cucumber ( Cucumis sativus ) rotations to examine the longterm residual effects of tomato methyl bromide (MBr) alternatives on soilborne pests in double-cropped cucumber. Four treatments were established in tomato fields: a) nontreated control; b) MBr + chloropicrin (Pic) (67:33 by weight) at a rate of 350 lb/acre; c) tank-mixed pebulate + napropamide at 4 and 2 lb/acre, respectively, followed by 1,3-dichloropropene (1,3-D) + Pic (83:17 by volume) at 40 gal/acre; and d) napropamide at 2 lb/acre followed by soil solarization for 7 to 8 weeks. Each of the following seasons, cucumber was planted in the same tomato plots without removing mulch films. For nutsedge [purple nutsedge ( Cyperus rotundus ) and yellow nutsedge ( C. esculentus )] densities, napropamide followed by solarization plots had equal control (≤15 plants/m 2 ) as MBr + Pic during all four cropping seasons. However, nematode control with solarization was inconsistent. Marketable yield data proved that fumigation in tomato fields with either MBr + Pic or pebulate + napropamide followed by 1,3-D + Pic had a long-term effect on double-cropped cucumber.
