Asocijacija sa edifikatorskom vrstom Diplotaxis muralis (L.) DC. do sada nije opisana u Bosni i Hercegovini. U sintaksonomskom pregledu vegetacije Srbije (Kojić et al., 1998) konstatovana je asocijacija Amarantho (blitoides)-Diplotaxietum muralis Mijatović 1971 svrstana u svezu Eragrostion Tüxen 1950. Asocijacija Diplotaxietum muralis (ass. nova) u vinogradima Bosne i Hercegovine pokazuje regionalnu osobenost uslovljenu klimatskim karakteristikama, te je optimalno razvijena u vinogradarskom rejonu Hercegovina. Asocijacija je svrstana u mediteransku sintaksonomsku jedinicu (Diplotaxion Br.-Bl. 1931 em 1936 iz reda Chenopodietalia mediterranea Br.-Bl. 1931 em 1936) koja se značajno razlikuje od sintaksonomskih jedinica eurosibirske regije (Polygono-Chenopodion Koch 1926 em Sissing. 1946 i Eragrostion Tüxen 1950) prvenstveno po učešću termofilnih vrsta. Sastojine asocijacije Diplotaxietum muralis (ass. nova) izgrađuje 38 vrsta. Od ukupnog florističkog sastava asocijacije 68,42 % vrsta su karakteristične za asocijaciju i više sintaksonomske jedinice, što govori da je asocijacija tipično izražena i optimalno razvijena u vinogradima rejona Hercegovina. Potpuni karakteristični skup asocijacije izgrađuju četiri vrste: Diplotaxis muralis (L.) DC., Convolvulus arvensis L., Chenopodium album L. i Setaria glauca (L.) Beauv. Analizom biološkog spektra asocijacije može se konstatovati izrazito terofitski karakter. Sastojine asocijacije Diplotaxietum muralis (ass. nova) su potpuno razvijene na cijeloj površini vinograda u ljetnjem i jesenjem aspektu. Areal spektar asocijacije u kojem učestvuje sedam grupa flornih elemenata se značajno razlikuje od konstatovanih asocijacija reda Chenopodietalia albi Tüxen, Lohm. et Prsg. 1950. Gradijentna analiza pokazuje najveću zavisnost florističkog sastava u odnosu na hemijsku reakciju podloge, nešto manju u odnosu na sadržaj azota u zemljištu i svjetlost, dok je najmanja zavisnost u odnosu na vlažnost zemljišta i temperaturu. Numeričkom klasifikacijom mogu se izdvojiti dvije grupe sastojina što preciznije potvrđuju rezultati ordinacije vršene korespondentnom analizom.

The protection of onions from the weeds and their negative impact in the field production is one of the most important measures. The onion is exceptionally succeptible to the weeds, especially in the first phases of the growth, considering the weak initial growth of the crop in comparison with the weeds. The seasonal dynamics of the onion weeds is not so noticeable like with the other crops, while the weeds that appear most frequently are: Amaranthus blitoides, Ambrosia artemisiifolia, Chenopodium album, Cirsium arvense, Convolvulus arvensis, Cynodon dactylon, Datura stramonium, Portulaca oleracea, Setaria glauca and Stellaria media. The chemical control measures mean the herbicide use before or after the emergence of the crop and the weeds. Before the emergence the herbicides based on aclonifen and pendimethaline can be used, while after the emergence herbicides based on fluroxypir, clopyralid, fluazifop-P-butyl, clethodim, quizalofop-P-ethyl, quizalofop-P-tefuryl and propaquizafop are used.

Ruderal flora, as well as the vegetation that flora forms, represent an extremely dynamic floristic-vegetation complex and arean integral part of the most immediate living and working environment of human. It is formed and developed mainly in human settlements, as well as in the other anthropogenic environments that are occasionally or permanently under direct or indirect influence of various forms of human activity. Ruderal vegetation is found not only directly around the settlements, but also around all urban and accompanying facilities: along roads, paths and fences around houses, yards, walls and roofs, in avenues, on ruins, construction sites, landfills, along railway tracks, road and defense embankments, on wet and nitrified banks of rivers, near human settlements, in abandoned lawns, on the street walks with sandy areas, cemeteries, in degraded pastures, forests, etc. This essay presents the distribution and representation of economically harmful, invasive and quarantine weed species (Abutilon theophrasti, Agropyrumrepens, Amaranthusretroflexus, Calystegiasepium, Cirsiumarvense, Chenopodium album, Chenopodiumhybridum, Convolvulus arvensis, Cynodondactylon, Daturastramonium, Sonchusarvensis, Sorghum halepense, Xanthium strumarium…) at ten sites in the Nisava district. The assessment of species representation was done in two shootings (May and August) according to scale 1-4. The proper selection of herbicides depends, in a large extent, on the presence of dominant weed species and on the time of application.

AbstractChanges in antioxidant systems in soybean and associated weeds (Ambrosia artemisiifolia L., Chenopodium album L., Convolvulus arvensis L and Sinapis arvensis L.) were studied in relation to treatment with herbicides linuron and dimethenamid in the field experiment. Differences in the total superoxide dismutase (SOD) and catalase (Cat) activities were observed in plants after application of herbicide formulation. Quantities of superoxide (O2.-) and hydroxyl (·OH) radicals and malonyldialdehyde (MDA), reduced glutathione (GSH) and total polyphenols content were also determined. In addition to this, potential antioxidant activity of the plant ethanolic extracts were assessed based on the scavenging activity of stable DPPH free radicals. Results obtained suggest that plants investigated 1) expressed different antioxidant systems in response to herbicide treatment; 2) enzymatic and non-enzymatic protective mechanisms were complementary; 3) some weed species showed distinctive and combined activity of several biochemical parameters, such as Ambrosia artemisiifolia.

Medicinal plants in segetal communities of the Kałuszyńska Upland The herbal flora of agrocenoses of the Kałuszyńska Upland includes 137 vascular plant species. Apophytes (91species-66,4%) prevail over anthropophytes (46 species-33,6 %). Meadow (32 species), waterside (20 species) and forest apophytes (17 species) were the most numerous. Short-lived plants (71 species) prevail over perennials (66 species) in the analysed flora. Therophytes (65 species) and hemicryptophytes (48 species) were the dominant life forms. Very rare, rare and quite rare species were the most frequent in the flora of the Kałuszyńska Upland. They build up over 63% of the total number of species. The share of common and very common species was about 8%. Some of them, e.g, Equisetum arvense, Chenopodium album, Viola arvensis, Anthemis arvensis, Centaurea cyanus, Cirsium arvense, Elymus repens Convolvulus arvensis, Capsella bursapastoris and Stellaria media were noted with a high ground cover. The occurrence of species rare in the region and in Poland among recorded medicinal plants, e.g., Camelina microcarpa sp. sylvestris, Hypericum humifusum, Consolida regalis, Asperugo procumbens and Herniaria glabra is especially noteworthy.

Control of littleseed canarygrass (Phalaris minor Retz.), wild oat (Avena fatua L.), common lambsquarters (Chenopodium album L.), and field bindweed (Convolvulus arvensis L.) in dwarf wheat (Triticum aestivum L.) fields was studied with five herbicides and hand weeding. Terbutryn [2-(tert-butylamino)-4-(ethylamino)-6-(methylthio)-s-triazine] and 1-benzthiazol-2-yl-1,3-dimethylurea controlled the weeds more effectively than did two hand weedings. Diuron [3-(3,4-dichlorophenyl)-1,1-dimethylurea], nitrofen (2,4-dichlorophenyl p-nitrophenyl ether), and dichlormate (3,4-dichlorobenzyl methylcarbamate), proved only partially effective against weeds, and were therefore significantly inferior to two hand weedings. Spikes per meter of row length and test weight of wheat were increased significantly by 1-benzthiazol-2-yl-1,3-dimethylurea (1.5 to 2 kg/ha), terbutryn (0.5 kg/ha), and two hand weedings over the yields of the weedy check. The 1-benzthiazol-2-yl-1,3-dimethylurea showed a high degree of selectivity in the wheat crop at 2 kg/ha and increased yields to those of weed-free plots. Terbutryn was almost as effective as 1-benzthiazol-2-yl-1,3-dimethylurea, which increased the wheat yields over those of the weedy check by 19.8 and 42.4% during the 1974/75 and 1975/76 seasons, respectively. Tolerance of dwarf wheat to terbutryn at 0.75 kg/ha was variable, resulting in significant decreases in yield components and grain yield. Dry-matter yield of wheat was negatively correlated with the dry matter production of weeds.

Uptake of 2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine (atrazine) as influenced by adjuvants to the treatment medium was studied using both excised leaf sections and leaves of intact plants. Uptake of the14C-atrazine label by yellow foxtail(Setaria glauca(L.) Beauv.) leaf sections was higher at 35 than at 5 C and at pH 3 and 9 than at 5 or 7. The rapid uptake of14C-atrazine label by corn(Zea maysL.) leaf sections was attributed to a high rate of atrazine metabolism. However, atrazine metabolism did not explain the greater uptake by common lambsquarters(Chenopodium albumL.) leaf sections than by yellow foxtail. Atrazine14C-label uptake by yellow foxtail leaf sections from exogenous solution was influenced by light, phospholipase D or water pretreatment, atrazine concentration, and oil. The14C-label of atrazine in the leaf distal to the treated spot was greater when the treatment contained an oil than when applied in only water even though the area of the spot was kept constant. Further, greater uptake of the label occurred at a high than at a low temperature regardless of the application medium.

Rumex crispus L. is an invasive species widespread in our country and in particular in the region of North Bulgaria. It is characterized by high biological and ecological plasticity. Owing to its great reproductive potential, the weed has been assigned to the list of economically most important weeds in the country. With the purpose of studying the possibility of chemical weed control in noncropped areas with heavy natural background infestation with R. crispus L. and other dicotyledonous weeds, two field trials were carried out. A ready-to-use herbicide mixture 2,4-D 140.2 g/l-1 + Triclopyr 144 g/l-1, trade product Genoxon 3X (X0050), was tested at two doses of active ingredient, 3552 and 2842 ml/ha-1. It was found that: (1) population density of Rumex crispus L. can be successfully reduced by treatment at the stage of early stem formation; herbicide efficacy with 3552 and 2882 ml/ha-1 doses on the 21st day after treatment was 100% and 90.5%, respectively, at the end of vegetation 94.4 and 85.7%, respectively; (2) herbicidal efficacy was lower when R. crispus L. was treated at the 5 - 6 leaf stage, being 100 - 94.1% and 80 - 76.5% respectively for the indicated doses and time of recording; (3) at the studied doses the herbicide controlled both annual dicotyledonous weeds (Amaranthus spp., Chenopodium album L., Portulaca oleracea L.) and perennial dicotyledonous ones (Cirsium arvense L., Sonchus arvensis L., Convolvulus arvensis L., Carduus acanthoides L.), but it was not toxic to monocotyledonous weeds.
