This study provides a detailed analysis using data on chemical plant protection measures for winter wheat (<em>Triticum aestivum</em> L.) taken from 40 farms across four regions in Germany between 2010 and 2018. These high-yield winter wheat regions correspond to administrative districts characterized by distinct regional patterns. This study analysed on-farm fungicide use intensity, described as treatment frequency (TF) and treatment frequency index (TFI), for each region. Linear mixed-effects models examined the effect of fungicide use intensity and management factors, including region, farm, year, soil tillage type, previous crop, and the growth stage at which fungicides were applied, on winter wheat yield.</div><div>Major temporal and regional variations in fungicide use were identified. Temporal variability in fungicide use was mainly attributed to climatic factors. Regional contrasts along north-south and west-east axes were observed, with the two northern regions having a higher fungicide use intensity than their more southerly counterparts and the two western regions having a higher fungicide use intensity than their more easterly counterparts. The results concerning the application of fungicides throughout the entire phenological growth stages (BBCH) of winter wheat indicated the greatest diversity of fungicide products used at around BBCH 31 and 61. The two northern regions showed higher frequencies of usage and a larger number of different fungicide products.</div><div>Based on the on-farm data, this study determined that the regional-level baseline for a potential 50 % reduction in TFI either exceeded or fell short of the nationally recommended reference baseline generated from JKI reference data. This presents some regions with challenges if they are to meet the consistent national objective of decreasing fungicide usage. These results highlight the importance of customising fungicide reduction targets according to temporal and regional factors, and demanding a comprehensive approach that incorporates scientific innovations, practical production methods, and policy and economic aspects. While this research uses Germany as a case study, the implications of region-specific fungicide reduction targets will also be relevant for other European member states in supporting efforts to achieve sustainable winter wheat production across diverse regions.</div></div>","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"196 ","pages":"Article 107281"},"PeriodicalIF":2.5,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144137834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 3rd-instar <em>A. aphidimyza</em> larvae induced stronger negative effects than 1st-instar larvae on reproductive performance of adult aphids, particularly when immature aphids were exposed to predatory cues at the 4th-instar. These results were likely due to intensified cue emission by larger and older <em>A. aphidimyza</em> larvae and the reproductive vulnerability of 4th-instar nymphs in response to predatory cues.

The aqueous extract prepared from oven-dried material (ES) exhibited the highest mortality, causing 92.93 % mortality at 10 % concentration after 24 h. In contrast, the methanol-formic acid extract from shade-dried material (GF) showed the strongest repellent activity (86.67 %) at 1 % concentration, with the effect persisting over 24 h. Biochemical profiling through LC-MS/MS identified major phenolic constituents, including rosmarinic acid, caffeic acid, <em>o</em>- and <em>p</em>-salicylic acid, <em>p</em>-coumaric acid, and protocatechuic acid. Rosmarinic acid was the most abundant phenolic compound, particularly in the GF. The extract also exhibited the strongest antioxidant activity (2073.42 mg GAE/100 g dry matter (dm)) in total phenolic content (TPC) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays. A positive correlation was observed between the salicylic acid content of the ES extract and its acaricidal activity. High levels of rosmarinic acid, caffeic acid, <em>p</em>-salicylic acid, and chrysophanol were detected in shade-dried methanol (GM) and oven-dried methanol (EM) extracts, which had the highest repellency. Drying methods and solvents significantly influenced biological activity: water extracts were more acaricidal on <em>T. urticae</em>, while methanol extracts were more repellent. These findings suggest that <em>T. orientalis</em> could serve as a natural alternative to synthetic acaricides, offering a safer option for integrated pest management in sustainable agriculture.

Researchers are exploring non-chemical and eco-friendly approaches for managing stored grain pests. One such approach is the use of light which exploits the phototactic behaviour to fight against storage insects by attracting and trapping or repelling them.

In this review, we attempted to gather the information and the study reports that focussed on the use of light to manage insect problems in food grain storage. Additionally, case studies showcase the practical application of this behavioural tendency for managing targeted insect pests in storage conditions.

Although insecticides have been a common pest control strategy, their limitations—including insecticide resistance and non-target effects, highlight the need for sustainable alternatives. This study explores the potential of allyl isothiocyanate (AITC), a plant-released volatile compounds, as a defense elicitor to mitigate aphid infestations.

Our results showed that higher concentrations of AITC (75 and 100 mg/L) significantly reduced aphid performance, particularly in terms of weight and development. In olfactometer bioassays, aphids exhibited a lower preference for plants treated with 100 mg/L AITC. Conversely, natural enemies demonstrated enhanced efficacy and preference for plants treated with 100 mg/L AITC, except in the aphid consumption bioassay.
