A series of novel 5-(4-hydroxybenzyl)-2-thioxoimidazolidin-4-one esters were synthesized under mild conditions by the reaction of 5-(4-hydroxybenzyl)-2-thioxoimidazolidin-4-one and carboxylic acids with DCC and DMAP as the promoters. Their structures were confirmed by ¹H-NMR, IR, ESI-MS and elemental analysis. The preliminary bioassy results indicated that some of compounds exhibit good herbici...

Anaerobically treated seedlings of Oryza sativa L. var arborio accumulated in their shoots more succinate than lactate and cell sap became alkaline. Conversely, in Triticum aestivum L. var MEK 86 lactate accumulation was far higher than that of succinate and cell sap was acidified. Anoxia clearly induced proton consumption in both species as an important means to prevent or counteract acidosis....

abstract to study the efficacy of glyphosate and nicosulfuron herbicides on barnyardgrass [echinochloa crus-galii (l.) p. beauv.] and velvetleaf (abotilon theophrasti medicus.) control and to find the ed50 index, experiments were conducted as factorial arrangement of treatments 2×7 based on completely randomized design with six replications for each weed in 2008-9 at research greenhouse, ferdow...

Gene mutations conferring herbicide resistance may cause pleiotropic effects on plant fitness. Knowledge of these effects is important for managing the evolution of herbicide-resistant weeds. An Echinochloa crus-galli population resistant to acetolactate synthase (ALS) herbicides was collected in a maize field in north-eastern Italy and the cross-resistance pattern, resistance mechanism and fit...
