Abstract

was grown on different natural substrates and its subsequent pathogenicity towards wheat, barley and ryegrass studied. This fungus caused more inhibition of plant growth of all test species when grown on root residues than when present as a spore suspension in sand. More wheat seedlings were killed when sown into infected ryegrass root residues than when sown into infected wheat or barley residues. However, when ryegrass was sown into infected ryegrass roots no plant death occurred compared with over 50% when sown into infected wheat or barley. Dressing ryegrass seeds with a formulation containing calcium peroxide gave some control of These results are discussed in relation to the problems that can sometimes occur following reseeding of grassland.
