Chancen und Grenzen der Biofumigation für die Bekämpfung pflanzenparasitärer Nematoden

Biofumigation is considered a promising nematode control alternative. In vitro tests confirmed the high nematicidal properties of isothiocyanates, the driving compounds of biofumigation. Its potential under temperate climate conditions was tested on a commercial farm. The tested biofumigation treatments reduced population densities of Pratylenchus spp. but had little effect on Meloidogyne hapla. The latter was most likely due to the good status of the tested varieties. To further optimize the biofumigation system non-host crops with high concentration of glucosinolates have to be selected
