摘要

2017年启动的一个旨在加快开发抗病草莓品种的重大合作项目正在紧急应对两个事态发展:对熏蒸剂使用的限制不断增加,以及出现了两种新的病原体,这两种病原体在允许的熏蒸剂下显然无法控制。作为该项目的一部分,我试图了解指导种植者选择品种的因素,并评估他们选择抗病原体品种以减少或可能取代熏蒸的意愿。通过对33名草莓种植者的调查和对20名种植者的深入采访,我发现大多数种植者在选择品种时优先考虑产量,尽管全行业都存在价格低的问题。很少有种植者表示,他们愿意用抗病品种代替熏蒸,而不会出现安全的疾病控制方法。许多种植者,即使是那些有现有有机项目的种植者,也会在更严格的监管环境中选择无土系统。因此,这项研究表明,抗病育种必须与支持其他疾病管理技术相结合,而让种植者感到不能放弃产量的经济状况也需要关注。

Strawberry growers are unlikely to forgo soil fumigation with disease-resistant cultivars alone
A major collaborative project launched in 2017 to accelerate the development of disease-resistant strawberry cultivars is responding urgently to two developments: increasing restrictions on fumigant use and the appearance of two novel pathogens not evidently manageable with allowed fumigants. As part of that project, I sought to understand the factors that guide growers' cultivar choice and assess their willingness to choose a pathogen-resistant cultivar to reduce or potentially replace fumigation. From a survey completed by 33 strawberry growers and in-depth interviews with 20 growers, I found that most growers prioritize yield in choosing cultivars, despite the industrywide problem with low prices. Few growers said they would be willing to substitute disease-resistant cultivars for fumigation without fail-safe disease control methods. Many growers, even those with existing organic programs, would opt for soilless systems in a tighter regulatory environment. This study thus suggests that disease resistance breeding must be coupled with support for other disease management techniques, and the economic situation that makes growers feel that they cannot forgo yield also needs attention.
