Dynamic of winter wheat foot and root diseases under different tillage systems.

摘要

Field experiments were conducted in 2002-03 in Poland to determine the stem base and root disease severity on winter wheat as affected by tillage systems. Take-all (Gaeumannomyces graminis) and brown foot rot (Fusarium spp.) were the main diseases occurring on winter wheat. The mean infection index and percentages of take-all and brown foot rot for winter wheat was higher in reduced tillage and no tillage systems than in conventional tillage..
