Brassica carinata for control of Phytophthora spp. in strawberry field crops

Soil biofumigation (SB) and soil solarization (SS) are nonchemical methods for the control of soilborne pathogens. SS uses solar radiation to heat soil and SB is based on the action of volatile compounds produced by the decomposition of Cruciferae, essentially glucosinolates (Gs) and isothiocyanates (ITCs). Brassica spp. are used as biofumigant because of their different concentrations and types of ITCs that are different in their toxicity against pathogenic fungi. Suppressiveness of the Brassica varies between species. Biofumigant effect depends on plant age and environmental growth conditions. Brassica carinata, the most effective species on the in vitro control of Phytophthora spp., was selected as biofumigant to evaluate and compare the ability of SB and SS to control Phytophthora spp. in soil and to enhance field production of strawberry. SB with B. carinata + SS reduce P. cactorum in soil and increases strawberry yield and fruit weigh.
