Many pesticides on the market use aromatic hydrocarbons as solvents. However, studies have revealed their potential risks to humans and the environment. Ethylene glycol diacetate (EGDA) is a low-toxicity and eco-friendly solvent with low utilization in pesticides. This study explores EGDA's potential to replace xylene. Results indicate that EGDA formulations enhance droplet adhesion to leaves, boosting pesticide efficiency. They exhibit lower surface tension and contact angles, with a 24%-40% increase in leaf retention. Bioassays show that 15% cyhalofop-butyl EC and 10% nicosulfuron OF with EGDA offer weed control that is superior to xylene-based formulations by 9.1%-30.5% in greenhouses and 4.8%-6.7% in fields. Xylene preparations are 2-3 times more cytotoxic to human bronchial cells than EGDA-based ones. Thus, EGDA is a promising pesticide solvent, outperforming traditional aromatic solvents in environmental friendliness and reducing adverse effects.","PeriodicalId":16712,"journal":{"name":"Journal of Pesticide Science","volume":"50 2","pages":"31-39"},"PeriodicalIF":1.5,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12256704/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144637290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies identified the metabolism of planteose, a storage trisaccharide in root parasitic weeds, as a potential control target. In Orobanche minor, α-galactosidase OmAGAL2 hydrolyzes planteose into sucrose upon perceiving germination stimulant strigolactones. Subsequently, invertases break down sucrose into glucose and fructose, essential for germination. This study screened chemical libraries to identify inhibitors against OmAGAL2-mCherry, secreted from transgenic tobacco BY-2 cells. Two inhibitors, 82-G8 and 85-B10, which significantly reduced the OmAGAL2 activity to less than 70% of the control, were evaluated for their impact on O. minor germination and sugar profiles. Results showed that OmAGAL2 inhibitors suppressed O. minor radicle elongation by inhibiting planteose metabolism, with effects more pronounced when applied at the start of conditioning rather than during germination stimulation. Further structural optimization could yield a novel class of chemicals for controlling Orobanche spp.","PeriodicalId":16712,"journal":{"name":"Journal of Pesticide Science","volume":"50 2","pages":"40-46"},"PeriodicalIF":1.5,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12246499/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144626587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The egg-dipping tests revealed highly effective ovicidal activity in the following insecticides: more than 8000 ppm for fenitrothion, 1000 ppm for acetamiprid, 400 ppm for clothianidin, and 500 ppm for dinotefuran (corrected egg-hatch rates of approximately less than 5%).
