Wheat is one of the most commercially important crops in the UK, but yield is greatly constrained by fungal diseases and insect pests. The cereal aphids _Rhopalosiphum_ _padi_ and _Sitobion avenae_ are major pests of wheat and cause yield losses through direct feeding on crops and transmission of viruses including BYDV and CYDV. This can cause large economic losses, e.g. BYDV would cost the UK wheat industry £136M per year if left untreated. Current control methods rely on synthetic chemical pesticides, but with regulatory constraints and increasing levels of resistance, new solutions are urgently needed.This project aims to identify fungal strains that have activity against both insect and fungal pests. It will build on existing work being done by FA-Bio to develop novel biofungicides, by developing a dual-action biofungicide and bioinsecticide to target pests and diseases in UK cereals. A dual-action product would have significant benefits for farmers including reducing the costs associated with multiple applications of chemical pesticides, reducing mechanical damage from repeated spray applications and reducing crop yield losses.This project will carry out laboratory trials to identify fungal strains that cause mortality in _R. padi_ and _S. avenae_ which also have biofungicidal activity. The ability to scale-up production of these fungi will also be tested as will their shelf life properties, to ensure they are compatible with current industry production standards. The most promising fungal isolates from lab-based trials will be used in glasshouse trials to test their efficacy against aphids on wheat in a controlled environment. Following this, fungal isolates will be tested in field trials for their ability to protect wheat from insect pests (_R .padi_ and _S. avenae_) and fungal diseases (such as take-all and Fusarium head blight). Following these experiments, the best performing isolates will be selected for commercialisation.

小麦是英国最重要的商业作物之一，但产量受到真菌病害和害虫的严重限制。谷类蚜虫 Rhopalosiphum 、padi 和 Sitobion avenae 是小麦的主要害虫，它们通过直接取食农作物和传播 BYDV 和 CYDV 等病毒而造成产量损失。这可能会造成巨大的经济损失，例如如果不加以处理，BYDV 每年将使英国小麦产业损失 1.36 亿英镑。目前的控制方法依赖于合成化学农药，但由于监管限制和耐药性水平不断提高，迫切需要新的解决方案。该项目旨在鉴定对昆虫和真菌害虫均具有活性的真菌菌株。它将以 FA-Bio 现有工作为基础，开发新型生物杀菌剂，通过开发双效生物杀菌剂和生物杀虫剂来针对英国谷物的害虫和疾病。双重作用产品将为农民带来显着的好处，包括降低与多次施用化学农药相关的成本、减少重复喷洒造成的机械损伤以及减少作物产量损失。该项目将进行实验室试验，以确定导致 _R 死亡的真菌菌株。 padi_ 和 _S。 avenae_ 也具有生物杀菌活性。还将测试这些真菌扩大生产的能力及其保质期特性，以确保它们符合当前的行业生产标准。实验室试验中最有前途的真菌分离株将用于温室试验，以在受控环境下测试其对小麦蚜虫的功效。此后，将在田间试验中测试真菌分离株保护小麦免受害虫（_R .padi_ 和_S. avenae_）和真菌病害（例如全食和赤霉病）的能力。在这些实验之后，将选择表现最好的分离株进行商业化。
