Numerous species of the Asteraceae, the composites, are famous for their use in both traditional and conventional medicine. Reliable anatomical descriptions of these plants and of possible adulterations provide a basis for fast identification and cheap purity controls of respective medicinal drugs by means of light microscopy. Nevertheless, detailed comparative studies on root and rhizome anato...

Postrelease studies can provide data with which to evaluate expectations based on prerelease tests of biological control insects. In 2004, we observed Trichosirocalus horridus Panzer (Coleoptera: Curculionidae), the rosette weevil introduced into North America against Eurasian thistles, feeding on native tall thistle, Cirsium altissimum L. Spreng., in tallgrass prairie. In this study, we examin...

in a faunistic survey of cecidomyiid gall midges (diptera: cecidomyiidae) in isfraeen, joghatai, and jovein regions (north khorasan province) in 2012, three species, clinodiplosis cilicrus kiefer 1889, asphondylia anatolica skuhrava1998 and lasioptera carophila low 1874 were collected and identified from galls on cirsium arvense (l.), astragalus sp. and dacus carota l. respectively. these three...

A polymerase chain reaction (PCR) protocol that can be used to distinguish Pseudomonas syringae pv. tagetis from other P. syringae pathovars, including those that induce apical chlorosis in several plants of the Asteracaea family and in pea, and closely related P. savastanoi pathovars was developed based on DNA sequences from P. syringae pv. tagetis that are required for tagetitoxin synthesis. ...

A field experiment was conducted in the years 2008– 2010 at the Research Station of the Faculty of Agricultural Sciences, University of Life Sciences in Lublin, on brown soil with slightly acidic pH and average abundance of copper, zinc, manganese, and iron. The experiment was set up in a randomized split-plot design with four replications, with two methods for controlling weed infestation: I. ...
