Abstract

Presence of Drechslera siccans (Drech.) Shoemaker and D. andersenii Lam in seeds of ryegrass (Lolium perenne L.).

Abstract

Seed samples of 18 cultivars of L. perenne from 6 European countries (UK, Denmark, Germany, France, Belgium and Italy) were analysed for presence of Drechslera spp. using the freezing blotter test. Of the 18 seed samples examined, D. siccans [Pyrenophora lolii] was detected in 5 (Chantel, Condensa, Danny, Pamir and Vejo), D. andersenii was detected in 3 (Patora, Pleno, and Vejo) and D. sorokiniana [Cochliobolus sativus] was detected in 1 (Mirvan).
