Different responses of Echinochloa crus-galli and Echinochloa colona to Bisbyric-sodium (Nomineetm) [PDF]

Egyptian Journal of Botany, 2018
Echinochloa crus-galli and Echinochloa colona mostly grown as weeds in different economic crops and cause losses in their yield. Flooding and Crop rotation ca not suppress these weeds. Herbicides are widely applied to control barnyard grasses. Bisbyric-sodium was applied at FRD (Field Recommended Dose) on both species, the results of preliminary ...

Environmental Influences on Seed Germination and Seedling Emergence in Four Echinochloa Taxa

Agronomy
Echinochloa species are troublesome weeds that cause serious problems in paddy fields. Due to the fact that the genus Echinochloa comprises numerous species and subspecies, research on its seed germination and emergence ecology is still insufficient.

Echinochloa chloroplast genomes: insights into the evolution and taxonomic identification of two weedy species.

PLoS ONE, 2014
The genus Echinochloa (Poaceae) includes numerous problematic weeds that cause the reduction of crop yield worldwide. To date, DNA sequence information is still limited in the genus Echinochloa.

Identification of Herbicide-Resistant Barnyardgrass (Echinochloa crus-galli var. crus-galli) Biotypes in Korea

Weed & Turfgrass Science, 2014
The continuous use of acetolactate synthase (ALS) and acetyl-CoA carboxylase (ACCase) inhibitors has led to the selection of herbicide resistant barnyardgrass populations in direct-seeded rice fields of Korea. This study was conducted to identify herbicide resistant barnyardgrass biotypes and to determine the cross- and multiple-resistance of them. 25%

Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Sequencing report of the rRNA amplicons of Echinochloa crus-galli in Iraq

Bionatura, 2023
This study was conducted to identify the genetic polymorphisms of one wild grass sample species and assess the phylogenetic distribution these isolates occupy based on their internal transcribed (ITS) ribosomal sequences. This study amplified one genetic locus covering a portion of the ITS rRNA sequences.

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 ...
