摘要：

"Spain's methyl bromide (MB) Alternatives Project" has been demonstrating alternative fumigants for methyl bromide on strawberry in Huelva since 1997. Here, we describe our research carried out between 2008 and 2010. In all the trials 'Camarosa' was grown under high plastic tunnels between October and the end of May every year. Field trials with the same complete randomized block design and 1012 treatments were performed annually in two locations of Huelva ("Occifresa"-Moguer and "Cumbres Malvinas"-Palos de la Fra.). In 2009-2010, non-chemical treatments (biosolarization) were applied. In 2007-2008 and 2008-2009 the following ten treatments were applied: untreated control; MB+chloropicrin (50:50 w/w); sodium azide; dazomet + 1,3D (dichloropropene); 1,3D + chloropicrin (61:35 w/w); chloropicrin alone; DMDS (dimethyl disulphide) + chloropicrin; methyl iodide + chloropicrin (50:50 w/w); acrolein; and, furfural. In 2009-2010, for addition treatments were applied: biosolarization with fresh poultry manure (25,000 kg/ha), biosolarization with Brassica pellets (2,000 kg/ha), enzone and metam sodium shank-applied with Rotary Spader implement. Black root rot complex (Fusarium spp., Cylindrocarpon spp., Rhizoctonia spp., and Pythium spp.) and nematodes Meloidogyne hapla and Pratylenchus penetrans were the main phytosanitary problems related to the soil, and Macrophomina phaseolina was detected occasionally in the first two seasons. However, plant survival, fruit size and yields were optimal in both locations. In 2009-2010 at "Occifresa"-Moguer a higher percentage of dead plants was evidenced, and at an earlier stage than the previous growing seasons, mainly caused by Macrophomina phaseolina and Fusarium oxysporum. DMDS + chloropicrin, 1,3D + chloropicrin and chloropicrin alone were as effective as MB:chloropicrin. Biosolarization with fresh poultry manure (25,000 kg/ha) showed higher production than the untreated control.
