“…found BCN populations were lowered at 12 of 13 sites in Germany where resistant radish variety ‘Adagio’ was planted, and the best results were obtained where the cover crop was sown in July rather than August. Hauer et al . found resistant mustard reduced populations of BCN at five of eight environments tested between 2013 and 2014, also in Germany.…”

“…Following recommendations from a seed merchant, five brassica treatments were selected for sowing in a field experiment. Four of the treatments reportedly showed some resistance to BCN in bioassays performed on the varieties in Germany . These were: one Class 1 radish (with ≥ 90% resistance to BCN), two Class 2 radishes (70–90% resistance to BCN) and one Class 2 mustard.…”

“…Yield losses can be severe (30–40% on susceptible cultivars) and have been calculated at as high as £3.8 million per year in the UK . However, modern varieties of sugar beet with BCN tolerance may be able to overcome the majority of the yield losses . However, these tolerant varieties still lead to a build‐up of BCN populations, which pose a problem for future sugar beet crops in the infested field and increase the chance of infested soil transfer to other fields.…”

However, these tolerant varieties still lead to a build‐up of BCN populations, which pose a problem for future sugar beet crops in the infested field and increase the chance of infested soil transfer to other fields. BCN is also harmful to a wide range of crop species, particularly brassicas such as oilseed rape ( Brassica napus ) and, therefore, alternative methods of reducing populations are important, especially as chemical options for BCN control are no longer available …”

BACKGROUND: Beet cyst nematode, Heterodera schachtii Schmidt is a global threat to sugar beet crops, and is found in every major sugar beet growing region. Annual losses due to this nematode can be severe, being estimated at €90 m in Europe alone in the 1990s. Fortunately tolerant, resistant and partially resistant varieties have since been introduced which help to limit yield loss and are now widely being deployed in infested fields. However, understanding yield performance of these varieties has been difficult, especially when variety testing programmes usually require uninfested fields. RESULTS: For the first time, and in a standardised manner, we can now assess simultaneously the resistance of different varieties to BCN and their actual yield tolerance, by comparing them to varieties grown in uninfested micro-plots alongside those which are infested. This method provides new insights on variety yield performance and nematode reproduction over an entire growing season. In addition, the investigations are also been able to detect significant physiological differences in the development and growth of the tolerant varieties' canopies and leaf chlorophyll levels. CONCLUSIONS: Our findings are of direct benefit to sugar beet growers challenged by BCN. The standardised testing provides new information on predicted variety performance. We found that these tests are justified, as not all tolerant varieties respond in the same manner to nematode infestation. Therefore, these assessments will become a vital part of variety testing for sugar beet growers, allowing for tailored deployment of variety types and more informed decision making on-farm, helping to maximise yields whilst minimising nematode damage.
