The incidence of Aspergillus niger (black mould) was found to be high on seed produced in hot (desert) climates. The fungus was transmitted from contaminated seeds to the cotyledons and first true leaves of seedling onions grown under controlled cond

Temperature optima for growth of Aspergillus niger and A. flavus on agar lay between 30°C and 35°C; the optimum for A. fumigatus was 40°C. A. flavus grew less rapidly in culture than the other two species. These fungi were recovered when a single

Aspergillus niger colonies were present on 60-90% of the leaves sampled from onion crops grown under hot, tropical conditions (Shambat, Sudan), but only on 21 % of leaves in crops grown under temperate conditions (Wellesbourne, UK). The seed stocks u

Treatment of A. niger-inoculated onion seed with benomyl dust (1 g a.i./kg), or a foliar spray of thiram (0·4% a.i./ha) applied to plants grown from inoculated seed under temperate (UK) conditions reduced the incidence of A. niger in harvested crops

Summary Leek seeds (Allium porrum L.) cv. Winterreuzen were treated for 5 days in stirred bioreactors containing a -1.0 MPa polyethylene glycol (PEG 6000) solution. The level of dissolved oxygen was controlled from zero to approximately two and a hal

Laboratory and glasshouse experiments demonstrated that priming of carrot seeds infected with Alternaria dauci did not affect the rate of transmission of the pathogen. Iprodione applied as a dust to unprimed, infected seeds at 5 ga.i. per kg seed eff

Summary Three batches of leek seeds were osmotically primed successively in the same polyethylene glycol solution in a bubble column at a seed concentration of 100 g/litre for seven days at 15°C. Three batches of carrot seeds were similarly primed i

Isolates of Clasdosporium allii and Cladosporium allii-cepae grew at 20 o C and 15-20 o C respectively on 2.5% malt extract agar and both species tolerated a wide pH range with maximum sporulation of C. allii-cepae between 5-8.5. C. allii did not spo
