Field screening of biofumigant species for the reduction of potato cyst nematodes (Globodera sp.)

摘要: Summary Potato cyst nematodes (PCN) Globodera pallida and G. rostochiensis are the most problematic potato pests in UK. Management of PCN is often reliant on use nematicides; however, pesticide registration approval becoming increasingly stringent likelihood nematicides being retracted from commercial more probable. Biofumigation represents a potential alternative. The process involves growing green manure for maceration incorporation into soil whereby intracellular glucosinolate (GSL) molecules hydrolyzed to pesticidal volatiles such as isothiocyanate gases. experiment detailed this paper one first studies investigate biofumigant species blends efficacy against in-field, varietal suitability UK conditions. Statistical differences (P<0.001) egg viability were found between untreated control treatments, but no difference treatments was recorded. Overall, biofumigation shown reduce encysted by approximately 42%. Additionally, fresh (P=0.008) dry weight (P=0.044) biomass be variable blends. All biofumigants suitable conditions when grown September November.
