Rapeseed (Brassica napus subsp. napus; also known as oilseed rape) is the second most important arable crop in the UK. Uses of oilseed rape range from edible vegetable oils to biodiesel and animal feed. The recent disruption of international supply chains caused by the Russia-Ukraine conflict has resulted in the prices of oilseed rape nearly doubled between February and April 2022, demonstrating the global demand of the crop and benefits for the UK growers to increase its production. However, pest pressure in the UK (e.g. cabbage stem flea beetle, CSFB) has led to 15-20% yield losses annually. Due to difficulties with crop establishment caused by CSFB and subsequent poor grower returns, rapeseed crop area has been decreasing from 530,000 ha in 2019 to 307,000 ha in 2021. Because lack of fully effective crop protection control of CSFB, growers are relying on cultural Integrated Pest Management (IPM) techniques such as later drilling and companion cropping to control the pest but had limited success. In the proposed project, we plan to test and verify a novel seed-based treatment to prevent further CSFB feeding and damage to the rapeseed tissues with extremely low agrochemical inputs, providing crop protection to mitigate pest damage for an important UK crop - oilseed rape.

甘蓝型油菜（Brassica napus subsp.欧洲油菜（napus）;也称为油菜（oilseedrape））是英国第二重要的可耕种作物。油菜的用途从食用植物油到生物柴油和动物饲料。近期俄罗斯与乌克兰冲突导致国际供应链中断，导致油菜籽价格于二零二二年二月至四月期间几乎翻了一番，显示全球对该作物的需求以及英国种植者增加产量的好处。然而，英国的害虫压力（例如卷心菜茎跳甲，CSFB）每年导致15-20%的产量损失。由于CSFB导致作物种植困难及其后种植者回报欠佳，油菜籽种植面积由二零一九年的530，000公顷减少至二零二一年的307，000公顷。由于缺乏对CSFB的完全有效的作物保护控制，种植者依赖于文化综合害虫管理（IPM）技术，如后期钻探和伴随种植来控制害虫，但成效有限。在拟议的项目中，我们计划测试和验证一种新的基于种子的处理方法，以防止CSFB进一步取食和以极低的农用化学品投入对油菜籽组织的损害，提供作物保护以减轻英国重要作物油菜的害虫损害。
