我的应用研究项目的目标是在传统和有机生产系统中改善长岛蔬菜作物的重要病害管理。药草疾病,特别是罗勒霜霉病,在2008年纽约发现这种新疾病后成为另一个重点。这些疾病通常在美国东北部的其他地方很重要。为了实现这一目标,我正在进行研究,以增进我们对这些疾病的了解,并为害虫综合管理(IPM)计划开发有效的组成部分。具体而言,我确定疾病导致生物的来源,确定这些生物如何在作物之间存活,制定疾病检测后杀菌剂应用的开始,调查有利于疾病发展的因素,并使用这些信息进行杀菌剂应用。fungicide applications, and evaluate new control tactics including new resistant varieties and mustard biofumigation. Management practices for improving soil health, including reduced-tillage production systems and compost soil amendments, are being examined for their impact on plant diseases. Fungicide resistance can be an important consideration in managing diseases, therefore effort is devoted to studying its occurrence, its impact on disease control and its management. Diseases studied include basil downy mildew; powdery mildew, downy mildew, bacterial wilt and Phytophthora blight of cucurbit crops; late blight, Septoria leaf spot, tospoviruses, and powdery mildew of tomato; white rust of spinach; bacterial leaf spot of pepper; and black rot of crucifers. Research has also been conducted to determine the impact on plant productivity of ambient ozone, which reaches concentrations that cause acute foliar injury to many crops each summer on Long Island.
