Aptamer-based biosensors for the detection of neonicotinoid insecticides in environmental samples: A systematic review

Talanta, Journal Year: 2024, Volume and Issue: 275, P. 126190 - 126190

Published: April 30, 2024

Neonicotinoids, sometimes abbreviated as neonics, represent a class of neuro-active insecticides with chemical similarities to nicotine. Neonicotinoids are the most widely adopted group globally since their discovery in late 1980s. Their physiochemical properties surpass those previously established insecticides, contributing popularity various sectors such agriculture and wood treatment. The environmental impact neonicotinoids, often overlooked, underscores urgency develop tools for detection understanding behavior. Conventional methods pesticide have limitations. Chromatographic techniques sensitive but expensive, generate waste, require complex sample preparation. Bioassays lack specificity accuracy, making them suitable preliminary tests conjunction instrumental methods. Aptamer-based biosensor is recognized an advantageous tool neonicotinoids due its rapid response, user-friendly nature, cost-effectiveness, suitability on-site detection. This comprehensive review represents inaugural in-depth analysis advancements aptamer-based biosensors targeting imidacloprid, thiamethoxam, clothianidin, acetamiprid, thiacloprid, nitenpyram, dinotefuran. Additionally, offers valuable insights into critical challenges requiring prompt attention successful transition from research practical field applications.

Knowledge and practice of farmers on safe use and handling of chemical pesticides: in the case of Tigray, Northern Ethiopia

Journal of Integrated Pest Management, Journal Year: 2025, Volume and Issue: 16(1)

Published: Jan. 1, 2025

Abstract Globally, more than 2 million tons of pesticides are used every year, and many farmers use in violation the recommendations, which may lead to adverse health effects. The study aimed assess knowledge practices regarding handling chemical pesticides. A semi-structured questionnaire was developed cross-sectional data were collected from 306 sample using face-to-face interviews. Descriptive statistics χ2 tests analyze data. Farmers listed 10 most pesticide-consuming crops 22 common their farms, including abamectin (“extremely hazardous”) P,p′-DDT. Among participants, 53.6% 58.8% received training had awareness negative impact pesticides, respectively. Of total respondents, 54.9% never personal protective equipment 50.3% read pesticide labels. Moreover, 77.1% 74% respondents stored anywhere living room incorrectly disposed empty containers, respectively, while 34.7% harvested within 7 d after spraying. is significantly associated with farmers’ education (χ2 = 6.923; P 0.031) experience 9.487; 0.023). Generally, poor practice hence, it needs consistent follow-up recurrent minimize adopt integrated pest management as control method.

Antifungal and Toxicological Evaluation of Natural Compounds Such as Chitosan, Citral, and Hexanal Against Colletotrichum asianum

Horticulturae, Journal Year: 2025, Volume and Issue: 11(5), P. 474 - 474

Published: April 28, 2025

The Colletotrichum genus is one of the ten most relevant pathogenic fungi in post-harvest sector owing to its high infection rate tropical fruits; however, search for alternatives synthetic fungicides crucial because their adverse effects on health and environment. This study evaluated efficacy chitosan (CH), citral (CT), hexanal (HX) against asianum, as well toxicological potential these treatments. In vitro tests, 1.0% CH, 0.03% CT, 0.06% HX significantly inhibited fungal development parameters radial growth, sporulation, biomass, germination by 78–100% (p < 0.05). Furthermore, toxicity index was low moderate concentrations using cucumber tomato seed a model. Toxicokinetic predictions suggest that molecules do not pose danger human consumption, suggesting they are promising chemical control phytopathogenic fungi.

Limonlarda Bulunan Bazı Fungisit Kalıntıları Üzerine Evsel Gıda İşleme Yöntemlerinin Etkisi

Akademik Gıda, Journal Year: 2024, Volume and Issue: unknown, P. 288 - 302

Published: Dec. 21, 2024

Bu çalışmanın amacı, limon meyvesi ve ürünlerindeki bazı fungisit kalıntılarına evsel işleme yöntemlerinin etkilerini belirlenmektir. Araştırmada, işlenmiş ürünlerinde imazalil thiophanate-methyl kalıntılarının analizi için QuEChERS (Hızlı, Kolay, Ucuz, Etkili, Sağlam Güvenli) yöntemi başarıyla uygulanmıştır. Limonun meyve eti, suyu reçel gibi gerçekleştirilen analizler, pestisit kalıntı seviyelerinin %88 ile %100 arasında önemli ölçüde azaltılabildiğini ortaya koymuştur. durum, pestisitlerin fizikokimyasal özelliklerine (log Po/w değeri, polarite çözünürlük gibi) limonun biyolojik yapısına bağlanmıştır. Ancak, kabuğu rendelenmiş dondurulmuş kabuk ürünlerde seviyelerinde artış gözlenmiştir. artış, yüzeyinde birikme eğilimiyle ilişkilendirilmiştir. Sonuç olarak, faktörlerinin uygulanan yöntemlerine bağlı olarak değiştiği görülmüştür. Meyve faktörleri 1’den küçük bulunmuş, bu da işlemlerin kalıntılarını azaltmada etkili olduğunu göstermektedir. Öte yandan, kabuklu büyük olduğu birikiminin daha fazla tespit edilmiştir.
