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.

Soil greenhouse gas emissions under enhanced efficiency and urea nitrogen fertilizer from Australian irrigated aerobic rice production

Agrosystems, Geosciences &Environment, Volume 7, Issue 4, December 2024.
Abstract Aerobic rice production offers a promising solution to improve water use efficiency and reduce methane (CH4) emissions by minimizing water inundation. However, alternate water‐saving methods for rice cultivation can lead to “trade‐off” emissions of nitrous oxide (N2O).

Herbicidal Activity on the EW Formulation of the Selective Rice Herbicide Cyhalofop Butyl.

Journal of Weed Science and Technology, 1997
Cyhalofop butyl, [R-(+)-n-butyl-2-(4-(2-fluoro-4-cyanophenoxy) phenoxy) propionate] is a selective rice graminicide which can control up to the 5-6 leaf stage of Echinochloa crus-galli by foliar application. Japanese agricultural practice requires development of a granule formulation of cyhalofop butyl.

Evaluation of phytotoxic potential in Asteraceae plant extracts for biological control of Echinochloa crus‐galli and Echinochloa colona

Plant-Environment Interactions, Volume 5, Issue 5, October 2024.
This study evaluated the phytotoxic potential of methanol extracts from six Asteraceae plants against Echinochloa crus‐galli and Echinochloa colona. Cosmos bipinnatus extract exhibited the most stable inhibition, with significant effects on radicle and hypocotyl lengths of both weeds. The 60‐day‐old C.

Grain yield and quality responses to nitrogen application rate and timing in dry direct broadcast seeded rice under different weather conditions

Agrosystems, Geosciences &Environment, Volume 7, Issue 2, June 2024.
Abstract In rice (Oryza sativa L.) production, dry direct seeding is one of the most essential technologies to reduce labor input and to increase net income. Field experiments were conducted in southwestern Japan in 2019 and 2020 to determine the effects of nitrogen (N) application rate and timing on grain yield, lodging, grain appearance, and protein ...

Biochemical and Physiological Changes in Rice Plants Due to the Application of Herbicides1 [PDF]

Planta Daninha, 2016
The application of herbicides, even if selective, can cause biochemical and physiological changes, resulting in oxidative stress. This stress comes from the accumulation of reactive oxygen species produced due to exposure to the herbicide.

Syntenic analysis of ACCase loci and target‐site‐resistance mutations in cyhalofop‐butyl resistant Echinochloa crus‐galli var. crus‐galli in Japan

Pest Management Science, Volume 80, Issue 2, Page 627-636, February 2024.
The ACCase genes in Echinochloa crus‐galli was characterized through analyses using genomic information. Target‐site resistance (TSR) mutations were identified in three ACCase genes from Japanese populations. Abstract BACKGROUND Recently, suspected cyhalofop‐butyl‐resistant populations of allohexaploid weed Echinochloa crus‐galli var.
