What is Effects of fungicides on in vitro spore germination and mycelial growth of the phytopathogens Leptosphaeria maculans and L. biglobosa (phoma stem canker of oilseed rape) about?

## Abstract **BACKGROUND:** Phoma stem canker, caused by the coexisting related fungal pathogens __Leptosphaeria maculans__ (Des.) Ces. & de Not and __L. biglobosa__ Shoemaker & H Brun, is a major disease of winter oilseed rape in the UK. Annually, over 90% of UK crops receive at least one foliar application of fungicide, but little is known about the sensitivity of the more damaging __L. maculans__ and the less damaging __L. biglobosa__ to these fungicides. The effects of flusilazole, tebuconazole and Methyl Benzimidazole Carbamate (MBC) fungicides (benomyl and carbendazim) on the germination of ascospores, conidia and germ tube growth of both species were examined. Isolates collected from different oilseed rape crops in England and Wales were assessed for their mycelial growth on fungicide‐amended medium, and ED~50~ values were calculated. **RESULTS:** __Leptosphaeria maculans__ and __L. biglobosa__ differed in their sensitivity to fungicides. Conidial germination of __L. maculans__ was more sensitive to these fungicides than that of __L. biglobosa__. Isolates of __L. maculans__ had smaller ED~50~ values for mycelial growth for all fungicides tested than isolates of __L. biglobos
