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.

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.

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 ...

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 ...

Weed control and water‐seeded rice response to pyraclonil applied at different timings and in herbicide combinations

Crop, Forage &Turfgrass Management, Volume 10, Issue 1, June 2024.
Abstract Pyraclonil is a new herbicide to control weeds in California water‐seeded rice (Oryza sativa L.). The objectives of this research were to evaluate weed control and rice response from pyraclonil applied alone at different timings and when applied in combinations with other herbicides. In one field study, pyaclonil was applied at 0.3 lbs a.i. ac−
