Photodecomposition of a Herbicide, Butachlor
Journal of Pesticide Science, 1978 除草剤ブタクロール (マーシェット) をガラス上で薄膜状にして紫外線を用いて光分解を行なった結果, 分解は比較的速やかに進行し, 実験条件下で半減期は約1.5時間であった. TlcおよびGlcによる分析では少なくとも7種の分解生成物の存在を認めることができた. その中で2-chloro-2′,6′-diethylacetanilide の存在を標準品との比較によって確認し, 2-hydroxy-2′,6′-diethyl-N-(butoxymethyl)acetanilide, 1-chloroacetyl-2,3-dihydro-7-ethylindole およびN-2′,6′-diethylphenyl-2,5-dihydrooxazol-4-one の三化合物の存在をIRおよびGC ...

Aldo‐keto reductase may contribute to glyphosate resistance in Lolium rigidum
Pest Management Science, Volume 79, Issue 4, Page 1528-1537, April 2023., 2023 Two aldo‐keto reductase (AKR) genes were cloned from Lolium rigidum populations, and their expression was significantly induced by glyphosate or 2,4‐D treatment in resistant populations. Overexpression of each of the two AKR gene endows glyphosate resistance in transgenic rice, indicting a role of the AKRs in glyphosate resistance evolution in L ...

Herbicide‐resistant barnyardgrass (Echinochloa crus‐galli) in global rice production
Weed Biology and Management, Volume 23, Issue 1, Page 23-33, March 2023., 2023 Abstract Barnyardgrass (Echinochloa crus‐galli (L.) Beauv.), an annual species of the family Poaceae, is a major weed problem in rice‐producing countries throughout the globe. Synthetic herbicides can effectively control this grass in rice paddies, but the development of resistant biotypes after the continuous use of the same active ingredients has led

Labour‐saving technologies in smallholder agriculture: An economy‐wide model with field operations
Australian Journal of Agricultural and Resource Economics, Volume 67, Issue 1, Page 56-82, January 2023., 2023 Abstract Labour‐saving technologies are relevant for agricultural development. Yet, as this study shows, they are poorly integrated into agricultural production functions of economy‐wide models. We report a computable general equilibrium (CGE) model, which explicitly incorporating field operations (e.g.

Isolation and Characterization of Novel Butachlor-Degrading Bacteria from Rice Paddy Soils
Processes, 2023 Four different bacteria capable of degrading butachlor, as well as five different syntrophic pairs of bacteria able to break down butachlor, were isolated from rice paddy soils in Korea. Genetic and phenotypic analyses were conducted to better understand

International Journal of Inflammation, Volume 2023, Issue 1, 2023., 2023 Cigarette smoke (CS) was known for its effect of increasing oxidative stress that could trigger tissue injury and endothelial dysfunction mediated by free radicals and reactive oxygen species (ROS). ROS itself is a key signaling molecule that plays a role in the development of inflammatory disorders.

Journal of Sensors, Volume 2022, Issue 1, 2022., 2022 China is a big industrial producer, but also a big producer and user of chemical materials. Although the use of chemical materials has improved the level of industrialization, it has also caused harm to the environment and ecosystem. With the acceleration of China’s industrialization, more and more attention has been paid to the problem of chemical ...

Potential effects of rainwater-borne H2O2 on competitive degradation of herbicides and in the presence of humic acid [PDF]
, 2017 In a previous piece of work, we reported some preliminary experimental results showing that hydrogen peroxide at a concentration range frequently encountered in rainwater could lead to degradation of three common herbicides (diuron, butachlor and ...
