Use Optimization of Organic Wastes in Anaerobic Soil Disinfestation against Strawberry Charcoal Rot Root

The imminent removal of agrochemicals in Europe is directly affecting the strawberry sector Spain, specifically Huelva province. currently main producer country. lack efficient fumigants has led to rise soilborne diseases. Macrophomina phaseolina (the causal agent charcoal rot strawberries) generating serious problems with farmers. This work proposes optimize process anaerobic soil disinfestation (ASD) against M. crops as a more sustainable alternative than chemical fumigation. Two trials different inoculum doses were conducted, amending rice bran and residual extrudate carbon source for ASD evaluate propagule reduction. After ASD, these soils used crop strawberries growth chamber under controlled conditions assay disease Strawberry favored reduction over control, equaling efficacy Metam Sodium or even improving it some cases. Trichoderma spp. microbial activity could influence suppressive effect ASD. All amended treatments reduced propagules severity. Rice are suitable amendments be pathogen. resulting at 16.89 t/ha 25 days was similar most effective treatment (20 40 days) based on foliar Additionally, both equivalent treatment.
