With the expansion of saline-alkaline tolerant rice in China, effects salinity stress (NaCl) on quinclorac-resistant Echinochloa crus-galli (L.) Beauv (E. crus-galli) is unclear. In this study, growth chamber experiment was conducted to test germination and physiology seven populations E. with quinclorac-different resistance levels which were collected from Hunan province. The results showed th...

Barnyardgrass (Echinochloa crus-galli) biotypes, resistant to different herbicides, have been reported. An experiment was conducted to compare the growth characteristics of various barnyardgrass biotypes, (i.e., propanil-resistant from Poinsett County, Ark., quinclorac-resistant from Louisiana., quinclorac/propanil-resistant barnyardgrass from Craighead County, Ark., and susceptible barnyardgra...

The n-hexane extract of S. salignus plants inhibited ATP synthesis and two sesquiterpenes, the β-caryophyllene (1) and caryophyllene oxide (2) were isolated from this nonpolar fraction. Compound 1 inhibited by 42% the root elongation of Physalis ixocarpa seedlings at 50 µg/mL and by 53% at 150 µg/mL, whereas at 150 µg/mL this compound only inhibited root elongation of Echinochloa crus-galli by ...

This study isolated, determined, and quantified plant growth inhibitors in Japanese chestnut (Castanea crenata Sieb. et Zucc), a deciduous species native to Japan and Korea. In laboratory assays, C. crenata leaves showed strong inhibition on germination and seedling growth of Echinochloa crus-galli (barnyardgrass), Lactuca sativa (lettuce), and Raphanus sativus (radish). Laboratory and greenhou...

In anaerobic soil disinfestation (ASD), amended with a carbon source undergoes conditions accompanied by changes in microbial community composition and an increase the concentration of organic acids, primarily acetic butyric gases that are deleterious to plant pathogens, insects, potentially weeds. The purpose this study was explore efficacy ASD different sources on inactivation propagules vari...

an isolated fusarium anthophilum (a. braun) wollenweber (isolate 16c) has been considered as a candidate for microbial control of barnyard grass [echinochloa crus-galli (l.) p. beauv]. the effects of nutrition on conidiation, germination rate and germ-tube elongation of conidia of the fungus were evaluated. conidia yield, conidial germination and conidial germ-tube elongation of the fungus grow...

The effect of leaf detachment on chlorophyll fluorescence was analyzed for Zea mays, Cucumis sativus, Phaseolus vulgaris, and Echinochloa crus-galli. Results clearly indicate that detachment hastens the decrease in chlorophyll fluorescence during the course of chilling experiments. For maize and bean, the activity of photosystem II of chloroplasts isolated from detached leaves is lower than tha...
