synthesis and in vitro study of some new bis(thiadiazolyl-2h-pyrazolo[3,4-d][1,3]thiazole)-methanes as potential nematicides. | a new series of bis(pyrazolo[3,4-d][1,3]thiazoles) 7a-j has been synthesized and characterized via ir, 1h nmr, 13c nmr, ms and elemental analyses. all the newly synthesized compounds 7a-j have been assayed for their nematicidal activity against ditylenchus myceliophagus and caenorhabditis elegans by aqueous in vitro screening technique. the screened data reveal that the compound 7e is most effective against d. myceliophagus and c. elegans with ld50 of 160 and 180 ppm respectively and is almost e ... | 2010 | 24061880 |
dna polymorphism in the stem nematode ditylenchus dipsaci: development of diagnostic markers for normal and giant races. | dna polymorphism in the ditylenchus dipsaci complex was investigated using amplified fragment length polymorphism (aflp) to determine the relationships among populations growing mainly on vicia faba and to develop diagnostic markers. twenty-two populations of d. dipsaci originating from different geographical areas and one population of ditylenchus myceliophagus were used. aflp proved to be a powerful method to reveal intraspecific polymorphism even within the giant type. the analysis showed a c ... | 2003 | 14663526 |

paraphyletic genus ditylenchus filipjev (nematoda, tylenchida), corresponding to the d. triformis-group and the d. dipsaci-group scheme. | the genus ditylenchus has been divided into 2 groups: the ditylenchus triformis-group, and the ditylenchus dipsaci-group based on morphological and biological characters. a total of 18 populations belong to 5 species of ditylenchus was studied: ditylenchus africanus, ditylenchus destructor, ditylenchus myceliophagus and dipsaci, ditylenchus weischeri, the first 3 belong to the ditylenchus triformis-group, the last 2 the ditylenchus dipsaci-group. the species of ditylenchus triformis-group were c ... | 2016 | 27103870 |
synthesis and in vitro study of methylene-bis-tetrahydro[1,3]thiazolo[4,5-c]isoxazoles as potential nematicidal agents. | a series of methylene-bis-tetrahydro[1,3]thiazolo[4,5-c]isoxazoles 6 were synthesized by the reaction of chalcone derivative of methylene-bis-thiazolidinone 5 with hydroxylamine hydrochloride. the chemical structures of newly synthesized compounds were elucidated by ir, 1h, 13c nmr, ms and elemental analyses. the compounds 6a-g were evaluated for their nematicidal activity against ditylenchus myceliophagus and caenorhabditis elegans, compound 6e and 6f showed appreciable nematicidal activity. fu ... | 2010 | 20199825 |
