Strawberry (Fragaria × ananassa Duch.) is a high value crop grown in Mediterranean countries that benefits from chemical soil fumigation (up to 2006 with methyl bromide, and currently using other chemicals treatments such as dichloropropene plus chloropicrin). After the phased-out of methyl bromide, our group carried out a research in new techniques and non-chemical alternatives. In the last season (2012/2013), field trials were performed in two fields with different background soil chemical treatments: namely Fres-Gómez S.L. (Palos de la Frontera, Huelva) was soil fumigated with 1,3-dichloropropene:chloropicrin until 2008, and Occifresa S.C.A. (Moguer, Huelva) that was soil fumigated with methyl bromide until 2001. In addition, a number of chemical and biosolarization treatments were assessed to determine their influence on agronomic traits of strawberry including plant vigour, plant mortality and early and total yield production. The experimental design was a randomized complete block with eight soil treatments plus an untreated control. Each treatment was replicated three times. The treatments were: dazomet (20 g/m2) + dimethyl disulfide (30 g/m2), biosolarization with chicken manure (2.5 kg/m2), dazomet (20 g/m2) + 1,3- dichloropropene (30 g/m2), 1,3-dichloropropene: chloropicrin (40 g/m2), chloropicrin (40 g/m2), dimethyl disulfide (30 g/m2) + chloropicrin (10 g/m2), dazomet (50 g/m2) and dazomet (30 g/m2). Strawberry cultivar 'Florida Fortuna' was cultivated following conventional cultivation practices, using large plastic tunnels. In treated soils, yield was significantly higher and plant mortality was significantly lower compared with the untreated control, in both sites. Source
