Impact of Pre‐Emergent Herbicides and Soil Management on Weed Community Dynamics and Soybean Yield

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Pre‐emergent herbicides are key tools in managing herbicide‐resistant and hard‐to‐control weed species in soybean (Glycine max L.) cultivation. This study aimed to evaluate the effects of pre‐emergent herbicides on weed phytosociology, soybean phytotoxicity, and grain yield under different soil management systems and environmental conditions.

Fallout of certain ACCase-inhibitor and ALS-inhibitor herbicides on Culex pipiens larvae and pupae under laboratory conditions in Egypt

Scientific African, 2021
The potential toxicity of five selected herbicides i.e. bispyribac-sodium, penoxsulam, haloxyfop-p-ethyl, pinoxaden, and tralkoxydim, and a pyrethriod insecticide deltamethrin was determined on the early 4th instar larvae (after 24, 48 and 72-h exposure)

Immuno‐Haematological and Growth Responses of Nile Tilapia (Oreochromis niloticus) Exposed to Agricultural Effluents During Dry Season in Benin's Cotton Basin

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Pesticide residues pose a significant risk to aquatic ecosystems, fauna and human health. Yet, the physiological impact on aquatic organisms, especially fish exposed to pesticide residues in the dry season, remains unexplored, and even data on chronic exposure to pesticide residue mixtures under natural environmental conditions remains scarce.

Effect of Growth Stage on the Efficacy of Postemergence Herbicides on Four Weed Species of Direct-Seeded Rice

The Scientific World Journal, 2012
The efficacy of bispyribac-sodium, fenoxaprop + ethoxysulfuron, and penoxsulam + cyhalofop was evaluated against barnyardgrass, Chinese sprangletop, junglerice, and southern crabgrass when applied at four-, six-, and eight-leaf stages.

Current and future management challenges for globally invasive grasses, with special reference to Echinochloa crus‐galli, Panicum capillare and Sorghum halepense

Weed Research, Volume 65, Issue 2, March/April 2025.
Abstract Without appropriate and ongoing management interventions, weeds will continue to economically and environmentally disadvantage agricultural and natural ecosystems. For these management strategies to have long‐term sustained success, they need to carefully consider the biological aspects of the targeted weed.

Control of Echinochloa sp. in the Irrigated Rice Crop

International Journal of Agronomy, 2014
The species of Echinochloa (barnyardgrass) stand out among major weeds infesting rice cropping and damages are variable depending on the weed population, rice cultivar, and management practices adopted by rice farmers.

Sensitivity of difficult‐to‐control Palmer amaranth accessions to fluridone and diflufenican

Agronomy Journal, Volume 117, Issue 1, January/February 2025.
Abstract Palmer amaranth (Amaranthus palmeri S. Watson) has evolved resistance to herbicides targeting nine sites of action. Phytoene desaturase‐inhibiting herbicides remain among the few sites of action that are still effective in controlling Palmer amaranth.

Cyanobacteria‐Pesticide Interactions and Their Implications for Sustainable Rice Agroecosystems

International Journal of Microbiology, Volume 2025, Issue 1, 2025.
Modern agricultural practices rely heavily on fertilizers and pesticides to boost crop yields, essential for feeding the growing global population. However, their extensive use poses significant environmental risks. Chemical‐based fertilizers and pesticides persist in ecosystems, potentially harming ecological stability.

Rice seedling and plant development as affected by increasing rates of penoxsulam under controlled environments Desenvolvimento de plântulas e plantas adultas de arroz em função de doses crescentes de penoxsulam em ambiente controlado

Planta Daninha, 2006
Rice is a major staple in many countries. Weed control is one of the factors limiting higher rice yield. ALS (acetolactate synthase)-inhibiting herbicides are desirable weed control herbicides because of their high efficacy, low toxicity to mammalians ...

Photolysis Products of Fluorinated Pharmaceuticals: A Combined Fluorine Nuclear Magnetic Resonance Spectroscopy and Mass Spectrometry Approach

Environmental Toxicology and Chemistry, Volume 43, Issue 11, Page 2285-2296, November 2024.
Abstract The aqueous photolysis of four pharmaceuticals with varying fluorinated functional groups was assessed under neutral, alkaline, advanced oxidation, and advanced reduction conditions with varying light sources. Solar simulator quantum yields were 2.21 × 10−1 mol Ei−1 for enrofloxacin, 9.36 × 10−3 mol Ei−1 for voriconazole, and 1.49 × 10−2 mol ...
