杀真菌化合物是广泛用于保护作物免受真菌感染的活性物质，但它们也可以杀死有益生物，进入食物链并促进抗性病原体菌株的过度使用。在这里，我们报告了第一次大田作物试验的均聚物材料，防止真菌附着，显示成功的作物保护，通过无活性的方法。在该试验中，将含有两种候选聚合物的制剂施用于经受小麦病原体Zymoseptoria triploid自然感染的小麦幼苗。含有一种候选聚合物，聚（二（乙二醇）乙醚丙烯酸酯）（简称DEGEEA）的制剂，产生了显着减少（26%），在感染的作物Z。三种杀真菌剂，提供对真菌感染的保护，与平行测试的三种不同的商业上建立的杀真菌剂方案相比是有利的。此外，喷洒的聚合物对小麦生长没有负面影响。这两种主要聚合物候选物最初是通过使用体外微量板和基于叶的测定进行生物性能测试来鉴定的，并成功地纳入一项计划，以优化和扩大其合成并将其复合成喷雾剂。因此，积极的田间试验结果也确立了小规模、基于实验室的生物测定数据和所用放大方法的有效性。由于真菌附着到植物表面是许多作物感染的第一步，因此这种非洗脱聚合物：（i）现在提供了提供针对真菌攻击的保护的显著潜力，同时（ii）通过使用设计用于保持功能功效同时降低毒性的化学产品来解决绿色化学的第四原则并与第十一原则一致。未来的重点应该是开发这种和其他应用（包括其他真菌病原体）的材料特性。无杀真菌剂的（甲基）丙烯酸酯聚合物喷雾剂有助于保护小麦作物免受真菌感染。
Fungicidal compounds are actives widely used for crop protection from fungal infection, but they can also kill beneficial organisms, enter the food chain and promote resistant pathogen strains from overuse. Here we report the first field crop trial of homopolymer materials that prevent fungal attachment, showing successful crop protection via an actives-free approach. In the trial, formulations containing two candidate polymers were applied to young wheat plants that were subject to natural infection with the wheat pathogen Zymoseptoria tritici. A formulation containing one of the candidate polymers, poly(di(ethylene glycol) ethyl ether acrylate) (abbreviated DEGEEA), produced a significant reduction (26%) in infection of the crop by Z. tritici, delivering protection against fungal infection that compared favourably with three different commercially established fungicide programmes tested in parallel. Furthermore, the sprayed polymers did not negatively affect wheat growth. The two lead polymer candidates were initially identified by bio-performance testing using in vitro microplate- and leaf-based assays and were taken forward successfully into a programme to optimize and scale-up their synthesis and compound them into a spray formulation. Therefore, the positive field trial outcome has also established the validity of the smaller-scale, laboratory-based bioassay data and scale-up methodologies used. Because fungal attachment to plant surfaces is a first step in many crop infections, this non-eluting polymer: (i) now offers significant potential to deliver protection against fungal attack, while (ii) addressing the fourth and aligning with the eleventh principles of green chemistry by using chemical products designed to preserve efficacy of function while reducing toxicity. A future focus should be to develop the material properties for this and other applications including other fungal pathogens. Fungicide-free (meth)acrylate polymer sprays help protect wheat crops from fungal infection.
