When pesticide reduction objectives meet business as usual: Possible impacts on the crop sector in Latvia

Resources Environment and Sustainability, Journal Year: 2024, Volume and Issue: 15, P. 100145 - 100145

Published: Jan. 4, 2024

The European Union (EU) has set forth ambitious political objectives aimed at mitigating the adverse impacts of agriculture on climate, environment, and human health. Among measures which are expected to help reach goals, an important objective is significant reduction pesticide usage, as outlined in EU's "From Farm Fork" strategy. This study seeks assess potential financial implications use, focusing major crops cultivated Latvia. Scenario simulations have been conducted examine consequences usage intensity profitability, yields, consumption fertilisers. evaluation encompasses winter spring wheat, along with rapeseed, account for 80% total It assumed that farmers continue produce same crops, using their current level knowledge adjusting production technology reduced pesticides application rates. analysis leads conclusion order attain a use by 61% from 2021 (or 53% 2015-2017 level), rate needs be limited 0.78 kg ha −1 active substance conventionally produced wheat well addition area used these should 33% (replaced organic production). However, if market prices amount public support costs do not change, agricultural sector could severe – yearly farm profit analysed decrease 41% or EUR 130 mln.

Structural Optimization of Natural Plant Products: Construction, Pesticidal Activities, and Toxicology Study of New 2-Isopropanol-4-methoxy-7-alkyl/aryloxycarbonyl-(E)-vinyl-2,3-dihydrobenzofurans

Journal of Agricultural and Food Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 9, 2025

Recently, the structural optimization of natural bioactive products has been one important ways to discover new pesticide candidates. Based on osthole as a lead compound, herein, series 2-isopropanol-4-methoxy-7-alkyl/aryloxycarbonyl-(E)-vinyl-2,3-dihydrobenzofuran derivatives were synthesized. Steric configurations compounds 3, 4, 6, 9, 11, 29, and 31 confirmed by X-ray monocrystallography. Notably, an efficient method for preparation 2-isopropanol-2,3-dihydrobenzofurans from epoxidation rearrangement reactions was developed. Against Plutella xylostella Linnaeus, compound (R = CH2CH2Ph; LC50: 0.759 mg/mL) displayed 1.9-fold insecticidal activity compared that osthole; against Tetranychus cinnabarinus Boisduval, 34 (CH2)9CH3; 0.401 exhibited 3.3-fold acaricidal good control effects those osthole. By scanning electron microscope (SEM) imaging method, it demonstrated may be related damage cuticle layer crest T. cinnabarinus. Compound could further studied potential acaricide.

Abstract Mediterranean spring ecosystems are unique habitats at the interface between surface water and groundwater. These support a remarkable array of biodiversity provide important ecological functions ecosystem services. Spring influenced by abiotic, biotic, anthropogenic factors such as lithology their draining aquifers, climate, land use recharge area, all which affect chemistry aquifer discharges. One most relevant characteristics is temporal stability environmental conditions, including physicochemical features water, across seasons years. This allows wide range species to benefit from these (particularly during dry periods), fostering an unusually high number endemic species. However, global change poses threats freshwater ecosystems. Changes in temperature, evapotranspiration, precipitation patterns can alter balance water. Eutrophication due agricultural practices emergent pollutants, pharmaceuticals, personal care products, pesticides, also growing concern for preservation biodiversity. Here, we synthesis main functioning We then describe value highlight risks face. Moreover, identify existing knowledge gaps guide future research order fully uncover hidden within understand drivers that govern them. Finally, brief summary recommended actions should be taken effectively manage preserve generations. Even though studies on still scarce, our review shows there sufficient data conclude viability functional under severe threat.
