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

Propanil tolerance inEchinochloa crus‐galli(L.) Beauv
Tropical Pest Management, 1989Abstract Two morphological variants of Echinochloa crus‐galli were collected from rice fields of an area in Greece where rice has been grown for over a decade and growers have recently been complaining about reduced effectiveness of propanil. Seedling response of the two variants to propanil was compared with that of E.

Target Site–Based Penoxsulam Resistance in Barnyardgrass (Echinochloa crus-galli) from China
Weed science, 2019Barnyardgrass [Echinochloa crus-galli (L.) P. Beauv.] is acknowledged to be the most troublesome weed in rice fields in Anhui and Jiangsu provinces of China.

Long-term herbicide application may facilitate the adaptive evolution of weed populations. With Echinochloa crus-galli var. crus-galli population A from a rice field used for the experiment of effectiveness of herbicide in Nanling County, Anhui Province, we conducted common garden experi-ments with seeds of population A and three control populations ...

Satisfactory Control of Echinochloa crus-galli in Rice Nurseries
PANS Pest Articles & News Summaries, 1969Abstract In field-scale trials at Hamoul in the north of the Nile delta in 1967 and 1968, certain herbicides applied to a soil heavily infested with barnyardgrass (Echinochloa crus-galli) gave very satisfactory results. Taking into account both grass control and increase in rice stand, molinate and propanil at 3-4 Ib/feddan* were shown to be most ...

Development and Germination of Barnyardgrass (Echinochloa crus-galli) Seeds
Weed Science, 1987Barnyardgrass [Echinochloa crus-galli(L.) Beauv. # ECHCG] spikelets were collected from greenhouse-grown plants at various developmental stages. Caryopses contained in a single spikelet were dormant at maturity, but dormancy was overcome when the spikelets were dry afterripened at 23 C or were treated with high temperatures, acid scarification, or ...

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-

Echinochloa species are problematic weed species in direct-seeded rice systems in Asia. Because of concern about the continuous use of single herbicides, cultural weed management strategies need to be developed to maintain the sustainability of direct-seeded rice systems.

Resistance of barnyardgrass (Echinochloa crus-galli) to atrazine and quinclorac
Pesticide Science, 1997Two populations of Echinochloa crus-galli (R and I) exhibited resistance to quinclorac. Another population (X) exhibited resistance to quinclorac and atrazine. The R and I populations were collected from monocultures of rice in southern Spain. The X population was collected from maize fields subjected to the application of atrazine over several years ...
