Effects of fungal diseases on linseed (Linum usitatissimum) growth and yield, 1988-1990
Fitt, Bruce D.L.; Ferguson, A.W. (1993-04)Effects of diseases on growth and yield of linseed (cv. Antares) were assessed by controlling diseases with fungicide treatments in field experiments at Rothamsted from 1988 to 1990. Fungicide seed treatments decreased the ... -
