Characteristics of wheat leaf diseases development in Latvia

Biruta Bankina, Ilza Priekule

Abstract


The field observations were carried out in 1999-2004 on 29 fields in Latvia. Incidence and severities of wheat leaf diseases were determined. Tan pot caused by Drechslera tritici-repentis and Septoria leaf blotch, induced by Septoria tritici were the most harmful diseases at the time of research (incidence 10-100% and 1-100%, respectively). Also the incidence of powdery mildew, caused by Blomeria graminis was high (4-100%), while that of rusts (Puccinia tritici and P. striiformis) was very low. Changes in disease epidemics were determined and showed the differences between the analyzed diseases.
