White mustard
Compared to fodder radish, white mustard has the advantage that it can be sown until the first half of September and will still result in decent ground cover. Variety selection characteristics are the same as for fodder radish.
The table below summarizes the results of the white mustard varieties registered on the Belgian variety list. This concerns data from 1986 to 2004.
One tetraploid variety is included (Chacha). When white mustard is propagated on plots with storage of non-resistant (against the beet cyst nematode) diploid plants, which occurs frequently in practice, tetraploidy protects against unwanted crossing. Crossing - even as little as 1% can completely nullify the total control effect against beet cyst nematodes.
Use one and a half times more seed weight for tetraploid varieties than when using diploid varieties (tetraploid varieties have heavier seed).
