Herbicides have been the primary tool for weed management to ensure food security a growing global population. However, excessive herbicide use raises concerns about environmental contamination, developing herbicide-resistant weeds, and potential human health risks. This necessitates exploration of ecologically sustainable practices in agriculture. The present study explored inter-field biodiversity (by sunflower hybrid mixture) reduce competitiveness along with reduced dose usage. experiment was conducted at Agronomic Research Area, University Agriculture, Faisalabad, autumn seasons 2022 2023 under randomized complete block design (factorial arrangement). experimental factors consisted mixture (FH-701 FH-648) monocultures each individual hybrids incremental doses lactofen quizalofop-p-ethyl as tank mixture. recommended herbicides usage caused impressive biomass reduction (81–83%) than monoculture (72–80%). Notably, maintained satisfactory suppression (up 75%) even 75% label (Lactofen: 135 g a.i. ha−1, quizalofop-p-ethyl: 281.25 ha−1). demonstrated strong yield performance, (83% control), similar monoculture. Importantly, statistically (2.29–2.36 t ha−1) dose. economic advantage confirmed by consistently high benefit-to-cost ratio, ranging up 1.62, exceeding that full application. These findings suggest offers promising approach effective weed, maintaining yield, promoting economically production reliance on herbicides.

Published: Jan. 9, 2025

Species-level crop and weed semantic segmentation in agricultural field images enables plant identification enhanced precision management. However, the scarcity of labeled data poses significant challenges for model development. Here, we report a patch-level synthetic generation pipeline that improves performance natural agriculture scenes by creating realistic training samples, achieved pasting patches segmented plants onto soil backgrounds. This effectively preserves foreground context ensures diverse accurate thereby enhancing generalization. The baseline was higher when trained solely on synthesized our proposed method compared to real data, with an approximate increase mean intersection over union (mIoU) approximately 1.1% (from 0.626 0.633). Building this, created hybrid datasets combining investigated impact volume. By increasing number these from 1× 20×, observed substantially improvement, mIoU 15% at 15×. gains diminish beyond this point, optimal balance between accuracy efficiency 10×. These findings highlight as scalable effective augmentation strategy addressing limited agriculture.

Ecotoxicological Effects of the Herbicide Metribuzin on Tenebrio molitor Hemocytes

Environments, Journal Year: 2025, Volume and Issue: 12(1), P. 30 - 30

Published: Jan. 19, 2025

Herbicides are synthetic chemicals that extensively employed in agricultural practices with the objective of enhancing crop yield and quality. Despite their selectivity for plant systems being generally regarded as non-toxic to animals, there is a paucity understanding surrounding sublethal effects on non-target organisms, including animals. This gap underscores necessity ecotoxicological research prioritizes identification suitable models develops reliable biomarkers early assessment environmental impact. In this context, hemocytes—circulating immune cells found invertebrates—have been identified crucial system assessing toxicological effects, given role defense overall organism health. Tenebrio molitor, beetle pest stored grain, was used model metribuzin-based herbicide (MTB, Feinzin DF 70, 70% metribuzin, 0.25 kg ha−1). Following 96 h exposure MTB, males (7–10 days post-eclosion) were examined multiple hemocytes, cell density, phagocytic activity, lysosomal membrane stability, cytological changes. Although no mortality observed, MTB resulted reduction index an increase blast-like cells, indicating potential immunotoxicity. Lysosomal stability reduced, though significant changes hemocyte density or nuclear morphology observed. These responses indicate impairment, which could affect beetle’s fitness reproductive potential. study highlights hemocytes raising concerns about ecological impact herbicides agroecosystems risks both wildlife human
