8858. Chan, M.K. and R.C. Close. 1987. Aphanomyces root rot of peas. 3. Control by the use of cruciferous amendments.. New Zealand J. Agr. Res. 30:225-233.
Growing Brassica napus in Aphanomyces euteiches infested soils for four months reduced the disease severity index (DSI) from 25-50% in three soils tested. There was no reduction in control soils with no plants, wheat, or red clover. Incorporation of dry leaves and stems of five cruciferous species also reduced DSI and oospore numbers. Reductions were greater after 6 weeks than after 3 weeks. Some species were more effective than others - Brassica napus was particularly good.
