The disease severity and spatial pattern of leaves with Septoria leaf blotch (Septoria tritici) symptoms was assessed two times in 1987 and three times in 1988 under conservation and conventional tillage (two locations each). Disease severity was higher under conventional tillage in 1987 (first assessment 86.2 and 39.8% vs. 22.2 and 7.5% [leaf 4], 24.3 and 11.5% vs. 4.3 and 3.6% [leaf 3]; second assessment [1987] 19.6 and 29.4% vs. 3.5 and 0.00% [leaf 3], 2.1 and 4.6% vs. 0.4 and 0.0% [leaf 3]), and at the first assessment in 1988 (...)
