Non-chemical alternatives to 1,3 dicloropropene + chloropicrine (AGROC) used for the control of Fusarium wilt of carnation were evaluated in field experiments. This disease is a limiting factor for carnation cultivation for two consecutive years in all the Mediterranean regions. This period is needed for an acceptable yield. Soil disinfection is based on composted organic matter combined or not with solarization and grouped under the denomination of biodisinfection: Several organic materials were tested: compost of alperujo with and without solarization (31 days), post-harvest residues of compost of carnation and chrysanthemum post-harvest residues with and without solarization, compost of carnation and chrysanthemum post-harvest residues + hen manure with and without solarization. The severity of the disease and flower production was weekly evaluated during the two years that lasted the experiment. Experimental results showed that soil biodisinfection using compost of carnation and chrysanthemum + hen manure + solarization confers a suitable protection against the Fusarium vascular wilt during two years. Production was significantly higher than with any of the disinfection treatments tested. Results also suggest that the combination of hen manure and standard high-density polyethylene film (HDPE) was the key factor to the success of the disinfection. There was no effect of solarization alone, possibly linked to the season of application.
