Health testing and evaluation of Leptosphaeria maculans (Phoma lingam) contamination in Brassica napus seed samples from Poland and England.
Mycological analysis and evaluation of L. maculans (Phoma lingam) contamination in Brassica napus seed samples from England and Poland were conducted. The results showed that 26-40% of the seeds were contaminated by fungi and bacteria, with Alternaria, Fusarium and Penicillium being the most commonly recovered genera. P. lingam contamination in Polish and English seed samples reached 0.5 and 0.6%, respectively, of which 7.1% of the Polish isolates and 12.3% of the English isolates were classified as Tox+pathotype. Seed surface sterilization prior to seed health testing improved the detection of P. lingam.
