ANTAGONISM IS THE PREDOMINANT EFFECT OF HERBICIDE MIXTURES USED FOR IMIDAZOLINONE-RESISTANT BARNYARDGRASS (Echinochloa crus-galli) CONTROL [PDF]

Planta Daninha, 2015
Herbicides mixtures are used in many situations without the adequate knowledge related with the effect on major target weeds. The objective of this study was to evaluate the effects of different herbicides mixtures used in irrigated rice in order to ...

The chemical cross talk between rice and barnyardgrass [PDF]

Plant Signaling & Behavior, 2011
The chemical cross talk between rice and barnyardgrass which is one of the most noxious weeds in rice cultivation was investigated. Allelopathic activity of rice was increased by the presence of barnyardgrass seedlings or barnyardgrass root exudates. Rice allelochemical, momilactone B, concentration in rice seedlings and momilactone B secretion level ...

Studies on the Germination of Barnyardgrass Seeds : 1. On the germination of barnyardgrass seeds sown in the irrigated and non-irrigated soils.

Japanese Journal of Crop Science, 1964
The germination (emergence) of one wild species and four cultivated variety barnyardgrass seeds was examined under the different soil conditions. The results obtained are as follows: 1. Any difference of the velocity of germination could not be found between 60% soil moisture (by weight) plot and moistened plot to soil capacity.

De novo assembly and characterization of the Barnyardgrass (Echinochloa crus-galli) transcriptome using next-generation pyrosequencing. [PDF]

PLoS ONE, 2013
Barnyardgrass (Echinochloa crus-galli) is an important weed that is a menace to rice cultivation and production. Rapid evolution of herbicide resistance in this weed makes it one of the most difficult to manage using herbicides.

Corn tolerance and weed control with amicarbazone and metribuzin applied preemergence

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Since the late 1950s, atrazine has been a cornerstone of corn (Zea mays L.) weed control, but decades of use have raised concerns about groundwater contamination and enhanced biodegradation. Therefore, amicarbazone and metribuzin were evaluated as alternatives to preemergence use of atrazine in corn.

Sorghum tolerance and weed control with amicarbazone and metribuzin applied preemergence

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Groundwater contamination has prompted the Environmental Protection Agency to consider restricting atrazine use, highlighting the need for alternative preemergence herbicides in grain sorghum (Sorghum Moench). Research was conducted in 2023 and 2024 to evaluate grain sorghum tolerance and weed control from preemergence applications of ...

Resistance of Echinochloa crusgalli var. mitis to Imazapyr+Imazapic Herbicide and Alternative Control in Irrigated Rice [PDF]

Planta Daninha, 2018
: The introduction of Clearfield® system for irrigated rice production provided an effective management strategy in the selective control of weeds. However, the selection pressure caused by the continuous use of herbicides such as imazapyr+imazapic ...

Analysis of glutamine synthetase target‐site mutations and their role in endowing glufosinate‐ammonium resistance

Pest Management Science, Volume 82, Issue 8, Page 7633-7644, August 2026.
GS2.2 G255D mutation conferred enzyme‐level glufosinate insensitivity but no whole‐plant resistance, showing trade‐offs between catalytic function and herbicide binding and providing a baseline for future studies on target‐site glufosinate resistance.

Endozoochorous dispersal of seeds of weedy rice (Oryza sativa L.) and barnyardgrass (Echinochloa crus-galli L.) by cattle

Ciência Rural, 2018
: The objective of this study was to evaluate endozoochory dispersal, recuperation, and germination of weedy rice (Oryza sativa L.) and barnyardgrass (Echinochloa crus-galli L.) seeds passed through the digestive system of cattle.
