Hatching of Globodera pallida is inhibited by 2-propenyl isothiocyanate in vitro but not by incorporation of Brassica juncea tissue in soil

摘要: Abstract The aim of this study was to assess the feasibility controlling potato cyst nematode Globodera pallida through biofumigation with glucosinolate-rich Brassica juncea genotypes. main glucosinolate B. is 2-propenyl which precursor isothiocyanate. Toxicity isothiocyanate encysted G. tested in vitro . Fifty percent reduction hatching found within 2 h exposure 0.002% Based on results, we hypothesized that would reduce vivo and higher levels have a stronger effect. Plant genotype, sulfur fertilization insect herbivory affected concentration However, increasing did not affect after biofumigation. absence effect most likely due lower concentrations compared conditions. These results show it difficult reach sufficiently high toxicity under realistic
