An effective basis for control of potato cyst-nematodes and assessment of the impact on soil health

植物寄生线虫每年给全球农业造成的损失高达1000亿美元。马铃薯孢囊线虫每年给英国马铃薯产业造成的损失估计为4300万英镑。控制通常依赖于杀线虫剂，这对环境和人类健康都有害，但在英国，经济马铃薯种植往往是必不可少的。我们已经开发了控制许多线虫包括马铃薯囊线虫的新抗性。这种拒食方法已被证明是有效的，在食品中完全安全，对环境无害。两份政府报告特别强调了它对英国农业的重要性。这项工作将开发这种方法，并通过将拒食剂与防止线虫吸引宿主根部的肽叠加来实现90%的抗性。其他线虫物种的数量和多样性将被用作土壤健康的指标。我们将确定使用肽是否对非靶线虫物种有任何影响。我们将开发方法，使线虫多样性进行评估，在大量的现场样本。这将增加一个进一步的适当的基础上，我们已经部署。我们希望评估我们的技术对该领域土壤生物的任何环境影响，并将其与它将取代的农药使用进行比较。

Plant parasitic nematodes cause losses to global agriculture of 100b dollars annually. Potato cyst nematode costs the UK potato industry an estimated 43 m pounds sterling/year. Control often depends on nematicides that are both harmful to the environment and possibly human health but often essential for economic potato cropping in the UK. We have developed novel resistance that controls many nematodes including potato cyst-nematodes. This antifeedant approach has been shown to be effective, completely safe in food and benign to the environment. It has been highlighted uniquely by two government reports for its importance to UK agriculture. This work will develop the approach and achieve 90 per cent resistance by stacking antifeedants with peptides that prevent nematode attraction to host roots. The number and diversity of other nematode species will be used as an indication of soil health. We will determine whether or not using the peptides has any effect on non-target nematode species. We will develop methods that will allow nematode diversity to be assessed in a large number of field samples.This will add a further appropriate basis to those we have already deployed. We wish to assess any environmental impact of our technology on soil organisms in the field and allow its comparison with the pesticide use it would replace.
