Our project is designed to facilitate the practical development of plant defence activators, such as cis-jasmone, as novel crop protection treatments for use against aphids. Earlier research has shown that cis-jasmone treatment can significantly reduce aphid infestations in the field and that treated plants become repellent to aphids while also becoming more attractive to natural enemies of pests. Plant defence activators have the advantage of having a non-toxic mode of action. They work by switching on (inducing) defence in plants and could provide new, environmentally friendly crop protection options. Farmers urgently need new options as conventional pesticide use is increasingly restricted by changes in legislation and compromised by evolution of resistance.Plant defence activators are:* environmentally friendly* work with not against natural enemies of pests* provide new interventions farmers can use against pests* form part of integrated pest management (IPM)* can be used against insecticide resistant pestsHere, we will make the next steps towards commercialisation of plant defence activator treatments. We have discussed with Agrii, a leading UK agronomy company, the research that would be needed. Wheat is their preferred crop for initial trials due to the large area it is grown in and also because our earlier field trials have already shown cis-jasmone can reduce aphid populations in wheat. Agrii have other potential plant defence activators (AGRII101, AGRII202) they would like to test alongside cis-jasmone in order to compare performance. Our project will therefore conduct field trials comparing different plant defence activator treatments with each other as well as with untreated control plots and plots treated with a standard pyrethroid insecticide. We will test the performance of plant activators with different wheat varieties because different varieties can have different capacity for inducing defence. Having tested efficacy under realistic conditions we will then explore with regulatory authorities how to obtain regulatory approval for for plant activators. The benefits listed above mean a strong case can be made for regulatory approval and we will include dialogue with regulators as a project objective.

我们的项目旨在促进植物防御激活剂（例如顺式茉莉酮）的实际开发，作为用于对抗蚜虫的新型作物保护处理剂。早期研究表明，顺式茉莉花处理可以显着减少田间的蚜虫侵扰，并且经过处理的植物对蚜虫具有驱避作用，同时对害虫天敌也更具吸引力。植物防御激活剂具有无毒作用模式的优点。它们通过开启（诱导）植物防御来发挥作用，并可以提供新的、环保的作物保护选择。由于传统农药的使用越来越受到立法变化的限制以及抗药性进化的影响，农民迫切需要新的选择。植物防御激活剂是：*环保*不针对害虫的天敌*提供农民可以用来对抗害虫的新干预措施*构成综合害虫管理 (IPM)* 的一部分，可用于对抗杀虫剂抗性害虫在这里，我们将采取下一步措施，实现植物防御激活剂处理的商业化。我们已经与英国领先的农学公司 Agrii 讨论了所需的研究。小麦是他们初步试验的首选作物，因为小麦种植面积大，而且我们早期的田间试验已经表明顺式茉莉酮可以减少小麦中的蚜虫数量。 Agrii 还有其他潜在的植物防御激活剂（AGRII101、AGRII202），他们希望与顺式茉莉酮一起进行测试，以比较性能。因此，我们的项目将进行田间试验，比较不同的植物防御激活剂处理相互之间以及与未经处理的对照地块和用标准拟除虫菊酯杀虫剂处理的地块的比较。我们将测试不同小麦品种的植物激活剂的性能，因为不同品种具有不同的诱导防御能力。在实际条件下测试功效后，我们将与监管机构探讨如何获得植物活化剂的监管批准。上面列出的好处意味着可以为监管机构的批准提供强有力的理由，我们将把与监管机构的对话作为项目目标。
