Chiral 3,3a,5,9b-tetrahydro-2H-furo[3,2-c][2]benzopyrans (TFBs) were synthesized and some of them were found to be herbicidally active against annual paddy weeds through intensive structure–activity relationship studies. These compounds were synthesized from D-glucose, which was used as a natural chiral source. This was the result of a series of studies based on the findings that certain benzyl...

Dicamba plus glyphosate (DpG) tank mixture has been widely adopted for broad-spectrum weed control. However, recent studies indicated antagonistic interactions between these herbicides. Furthermore, little is known about the effect of non-ammonium sulfate water conditioner (non-AMS WC) adjuvant on activity DpG mixture. Thus, present study was elaborated to evaluate (1) interaction mixtures comb...

Abstract The genus Echinochloa constitutes some of the most prominent weed species found in rice ( Oryza sativa L.) production worldwide. taxonomy is complex due to its morphological variations. morpho-physiological diversity and taxonomic characteristics ecotypes infesting fields Texas are unknown. A total 54 collected during late-season field surveys 2015 2016 were characterized a common gard...

Enolase (2-phospho-o-glycerate hydrolase, EC 4.2.1.1 1 ) has been identified as an anaerobic stress protein in Echinochloa oryzoides based on the homology of i ts interna1 amino acid sequence with those of enolases from other organisms, by immunological reactivity, and induction of catalytic activity during anaerobic stress. Enolase activity was induced 5-fold in anoxically treated seedlings of...
