Collaborative project: Optimization of biofumigation for the non-chemical control of soil-borne pathogens – Subproject 1

Project


Project code: 2814201806
Contract period: 01.07.2007 - 30.06.2010
Budget: 95,242 Euro
Purpose of research: Experimental development

The research project studied the effect of optimized biofumigation to control soil-borne fungi and plant-parasitic nematodes in temperate regions. Biofumigation is a cultivation method based on growing cruciferous plants high in glucosinolates. At the stage of fill blossom plants are chopped and incorporated into the soil. During this process, glucosinolates are converted into isothiocyanates that have fungicidal and nematicidal potential. It was shown that isothiocyanate production per hectare can be enhanced by growing cultivars with high levels of glucosinolate, optimized fertilization with N and S and planting time, finely chopping of the biomass and supplementary irrigation to extend retention time of the active compounds in the soil. Under such conditions, biofumigation was able to reduce Rhizoctonia solani on lettuce and Sclerotinia sclerotiorum on beans. However, its affect towards Meloidogyne hapla and Pratylenchus penetrans was not better than standard control measures.
