d(+) and 1(-) Methyl-2-chloro-3-(4-chlorophenyl)-propionate (common name chlorfenprop-methyl; trade mark Bidisin) were prepared and their herbicidal activities studied on Avena fatua L. and Avena sativa L. ("Flämingskrone"). The 1(-) enantiomer was found to be twice as active as the racemate; the d(+) form almost inactive.

Background: The use of allelopathic plant extracts as herbicide is being popularized in recent years. Objective: This research has been conducted to evaluate the allelopathic potential of caltrop (Tribulus terrestris L.) on seed germination and growth of Avena fatua L., Chenopodium album L., Setaria viridis L. and Amaranthus retroflexus L. Methods: This research was done to evalature the ef...

Avena fatua and Phalaris minor are narrow-leaved weeds that pose problems for many crops. In order to study the effects of sodium chloride (NaCl) and polyethylene glycol (PEG) on germination and initial seedling growth of Avena fatua and Phalaris minor, an experiment was conducted based on a completely randomized design with 4 replications under laboratory conditions during 2011-2012. Eight lev...

Allelopathic effects of aqueous extract of rhizomes of  Cynodon dactylon L. were studied on seed germination and seedling growth of three legume crops (Phaseolus vulgaris L., Pisum sativum L., and Vicia faba L.), three Labiatae species (Thymus vulgaris L., Melissa officinalis L., and Mentha spicata L.), and two species of Poaceae (Avena fatua L., Sorghum halepense L.). Seed germination of all L...

a multivariate statistical analysis was performed on morphological characters of sixty-one populations of avena eriantha dur. a. clauda dur., a. barbata pott ex link., a. wiestii steud., a. fatua l., a. sterilis ssp. ludoviciana l. and a. sativa l. factor analysis revealed that intraspecific morphological variations are due to quantitative characters. interspecific as well as intersectional rel...
