| Incidence of disease may vary with location and environment | |||||
| White mould test results should be used as only a general guide in variety selection. Ratings could change with weather and location. Grower's with white mould problems should consider crop rotation with a non-host crop, selection of early varieties, wider row spacing and avoiding heavy applications of manure, in addition to selecting varieties with the lowest plant infection. |
