Abstract


Three field trials were conducted to compare the effect of selected methyl bromide (MBr) alternatives on strawberry (Fragaria ananassa Duch.) yield and soilborne pest control in Spain and Florida. Fumigant treatments were MBr + chloropicrin (MBr + Pic; 67:33 and 50:50 v/v, in Florida and Spain, respectively) at a rate of 270 lb/acre, 1,3-dichloropropene (1,3-D) + Pic (65:33 v/v) at 24 gal/acre, Pic at 268 lb/acre, propylene oxide (PO) at 71 gal/acre, and dimethyl disulfide (DMDS) + Pic (50:50 v/v) at 223 lb + 223 lb/acre. A non-treated control was also included. In both locations, use of fumigants resulted in higher early and total marketable yields than in the non-treated control plots. Yield in plots treated with 1,3-D + Pic, Pic, and DMDS+ Pic did not differ from that with MBr + Pic.
