Echinochloa crus-galli (barnyard grass).
2021Abstract E. crus-galli is a grass species included in the Global Compendium of Weeds (Randall, 2012) and which is considered one of the world's worst weeds. This species has the capability to reduce crop yields and cause forage crops to fail by removing up to 80% of the available soil nitrogen. E. crus-galli is considered the world's

Multiple resistance mechanisms to penoxsulam in Echinochloa crus-galli from China
Pesticide Biochemistry and Physiology, 2022Penoxsulam is an important herbicide for the control of Echinochloa crus-galli (L.) P. Beauv. Two resistant populations 17GA (R1) and 16NXB (R2) showed 17- and 3-fold resistance to penoxsulam, respectively. A known resistance mutation of Trp-574-Leu in ALS gene and enhanced rates of penoxsulam metabolism likely involving GST contribute to penoxsulam ...

Eco-biology and management of Echinochloa crus-galli
Crop Protection, 2015Weed management is one of the most important aspects in successful crop production, and with the passage of time, ecological and biological aspects are becoming more significant. Echinochloa crus-galli (L.) Beauv. is among the most noxious weeds in the world due to its superior biology and tremendous ecological adaptations.

Pollen‐mediated transfer of herbicide resistance in Echinochloa crus‐galli
Pest Management Science, 2014AbstractBACKGROUNDPollen‐mediated gene flow (PMGF) can facilitate the dispersal and spread of herbicide resistance from one weed population to another within an agricultural landscape. The aim of this study was to quantify the extent of PMGF in Echinochloa crus‐galli (barnyardgrass), an important herbicide‐resistant weed species in the United States ...

Bioherbicidal activity of terpenes and phenylpropenes against Echinochloa crus-galli
Journal of Environmental Science and Health, Part B, 2019This study was undertaken to evaluate the herbicidal activity of twelve natural compounds belonging to monoterpenes, phenylpropenes, and sesquiterpenes against Echinochloa crus-galli under laboratory and glasshouse conditions. Experiments were conducted to determine the impact of different concentrations (0.5, 1, 2, 4 and 8 mM) of these compounds on ...

Geographic variation in seed dormancy among populations of Echinochloa crus-galli
Oecologia, 1996In 1991-1993, we investigated the incidence of seed dormancy in 25 local populations of barnyard grass, Echinochloa crus-galli (L.) P.Beauv., in the western Czech Republic. The percentage of germination after 4 months afterripening of dry seeds at 25°C varied between 0.0 and 83.6%. Although there were significant annual differences in the percentage of

Lipid biochemistry of echinochloa crus-galli during anaerobic germination
Phytochemistry, 1984Abstract Seven day old seedlings of Echinochloa crus-galli var. oryzicola (Vasing) had a higher total lipid content when germinated under N 2 than in air, although ungerminated seeds contained more lipid than either seedling. The triacylglycerol pool was not depleted under anaerobiosis as it was in air and only air-grown seedlings showed a net ...

Until recently Echinochloa muricata var. microstachya Wiegand (rough barnyardgrass), an alien species native to North America, was completely overlooked in Belgium due to its close morphological resemblance to Echinochloa crus-galli (L.) P. Beauv. (barnyardgrass). E. muricata var.

The complete chloroplast genomes of three Korean Echinochloa crus-galli accessions
Mitochondrial DNA Part A, 2015The complete chloroplast (cp) genomes of three Echinochloa crus-galli accessions (KR822684, KR822685, and KR822686) are reported in this work. The cp genome size is similar in three accessions, ranging from 139 846 bp to 139 860 bp. All three genomes have two inverted repeats (IR) of 22 748 bp per each IR with a large single copy (LSC) region of 81 833-
