Degradation Enhancement as the Mechanism of Resistance to Imazethapyr in Barnyardgrass [PDF]

Planta Daninha, 2018
: Non-target site (NTS) herbicide resistance by degradation enhancement is an increasing problem in several weeds around the world. In this study, the occurrence of degradation enhancement by cytochrome P450 monooxygenases (cytP450) was evaluated as the ...

Barnyardgrass

Weed Technology, 1990
Barnyardgrass [Echinochloa crus-galli(L.) Beauv. ♯3ECHCG], originally from Europe and India, now ranges from latitude 50 N to 40 S, in both temperate and tropical habitats (12). It is a serious weed problem in 42 countries and is found in at least 27 more (11).

Competition between rice (Oryza sativa L.) and (barnyardgrass (Echinochloa crus-galli (L.) P. Beauv.) as affected by methanol foliar application

Anais da Academia Brasileira de Ciências, 2015
Pot experiment was conducted in Iran, to evaluate the effect of methanol on competition between rice (Oryza sativa) and barnyardgrass (Echinochloa crus-galli).

Resistance Mechanism of Propanil-Resistant Barnyardgrass

Pesticide Biochemistry and Physiology, 1995
Propanil-resistant barnyardgrass was reported in Poinsett County, AR, in 1990. Greenhouse studies were initiated to determine the distribution of propanil-resistant barnyardgrass in the state and to characterize the resistance.

Separation of allelopathy from resource competition using rice/barnyardgrass mixed-cultures.

PLoS ONE, 2012
Plant-plant interference is the combined effect of allelopathy, resource competition, and many other factors. Separating allelopathy from resource competition is almost impossible in natural systems but it is important to evaluate the relative ...

Performance of an S‐metolachlor capsule suspension for barnyardgrass control and crop tolerance in fenclorim‐treated rice

Agrosystems, Geosciences & Environment
Barnyardgrass [Echinochloa crus‐galli (L.) P. Beauv.] is the most problematic weed of delayed‐flooded rice (Oryza sativa L.) systems in the mid‐southern United States. Recent findings suggest that acetochlor can achieve effective barnyardgrass control in

Distinct Defence Mechanisms of Allelopathic Rice Against Quinclorac-Susceptible and -Resistant Barnyardgrass: Involvement of Specific Metabolites and Rhizosheath Microbiota. [PDF]

Plant Biotechnol J
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,

Quick bioassay test from tillers for detecting ALS herbicide resistance of weedy rice and barnyardgrass

Bioscience Journal, 2023
Resistance to acetolactate synthase (ALS) inhibitors have increased recently in South Brazil where the major weeds of flooded rice (barnyardgrass and weedy rice) have evolved resistance to imazapyr+imazapic.

Unraveling the Role of P450 Reductase in Herbicide Metabolic Resistance Mechanism. [PDF]

Plant Direct
ABSTRACT Plants require cytochrome P450 reductase (CPR) to supply two electrons for cytochrome P450 monooxygenase enzymes (P450) to react with an organic substrate. The transfer of electrons to the P450 active site in the P450 catalytic site relies on a robust and intricate CPR:P450 complex in the endoplasmic reticulum membrane.

Herbicide resistant barnyardgrass in Iran and Turkey [PDF]

Planta Daninha, 2020
Abstract Background: Inconsistent control of Barnyardgrass has been reported repeatedly by farmers in major rice growing areas of Iran and Turkey. Objective: Thus, a greenhouse study was conducted to investigate the resistance of Barnyardgrass to acetyl CoA carboxylase (cyhalofop-butyl) and acetolactate synthase (penoxsulam, bispyribac-sodium ...
