Adjuvant Helping Effects on Foliar Application of Cyhalofop Butyl

Journal of Pesticide Science, 1999
シハロホップブチルの茎葉処理剤としての経済性及び効果の安定化を追求するために7種類のアジュバントの生物効果を屏東 (台湾) で評価した. 供試したアジュバントのうち特に優れた効果を示したアジュバント, アルキフェノールグリコールエーテル系の Polyglycol 26-2 (以下PG26-2と略記する) を選択した. PG26-2をシハロホップブチル30%乳剤に混用し, ヒエに対する効果, イネに対する薬害及び耐雨性に関して検討した. 2～3葉期のヒエを90%以上コントロールするにはシハロホップブチルの薬量が60gai/haの場合, 0.1～0.4%のPG26-2の添加を要した. また, 4～5葉期のヒエを90%以上コントロールするにはシハロホップブチルの薬量が120gai/haの場合, 0.2～0.

Susceptibility of Echinochloa populations to cyhalofop-butyl in Southern region of Brazil and impact of the weed phenology on its efficacy of control

Ciência Rural
: Cyhalofop-butyl stands out among the herbicides in the control of imidazolinone-resistant Echinochloa species; but, rice farmers are not always satisfied with the control achieved with this herbicide.

The Extruded Granule Formulation of Selective Rice Herbicide Cyhalofop Butyl.

Journal of Weed Science and Technology, 1998
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. The development of granule formulations for rice herbicides is important to strengthen agricultural practices in Japan.

Weed management in direct-seeded rice under a long-term conservation agriculture-based rice (Oryza sativa)-wheat (Triticum aestivum) system

The Indian Journal of Agricultural Sciences, 2022
Weeds that occur in repeated flushes pose major challenges to direct-seeded rice (DSR). Zero till (ZT) DSR with crop residue influences weed interference considerably and can be substitutive to resource-intensive puddled transplanted rice (PTR).

From knowledge to action: the importance of characterizing herbicide resistance mechanisms for implementing management strategies

Pest Management Science, EarlyView.
This review bridges the gap between understanding resistance mechanisms and applying them in weed management, highlighting how mechanistic insights reveal vulnerabilities that can guide more effective control strategies. Abstract Herbicide resistance remains one of the most intensively studied areas in weed science because of its direct consequences ...

Distinct Defence Mechanisms of Allelopathic Rice Against Quinclorac‐Susceptible and ‐Resistant Barnyardgrass: Involvement of Specific Metabolites and Rhizosheath Microbiota

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3876-3896, June 2026.
ABSTRACT Allelopathic rice is increasingly recognised as a promising strategy for sustainable weed management. Resistance to the herbicide quinclorac is widespread in barnyardgrass, but it remains unclear whether allelopathic rice exerts the same defence against herbicide‐susceptible and ‐resistant barnyardgrass. We conducted integrated transcriptomic,
