Field experiments were conducted at two locations in central Alabama to evaluate competitiveness of large crabgrass and southern sandbur with ‘Tifton 78’ hybrid bermudagrass as influenced by diuron application and sprigging rate. Large crabgrass was the more competitive species. In late season, bermudagrass ground cover with no weed competition was 96% compared with 72 and 81% where large crabgrass and southern sandbur, respectively, were present. Similarly, large crabgrass and southern sandbur reduced the proportion of bermudagrass in the cumulative harvested forage by at least 59 and 38%, respectively. Application of diuron preemergence (PRE) at 1.1 kg ai/ha was more effective than postemergence (POST) application, both in terms of weed control and bermudagrass safety. With diuron applied PRE, large crabgrass and southern sandbur reduced the proportion of bermudagrass in the harvested forage only 32 and 25%, respectively. Increasing bermudagrass sprigging rate was beneficial for weed control but of relatively minor importance compared with diuron PRE.

“…Interest in the adsorption of herbicides on soil colloids has resulted in many experimental attempts to relate soil properties and phytotoxicity. In addition to those by Sheets and Upchurch, studies on this topic have been reported by Sheets (1959), Jordan & Day (1962), Sheets, Crafts & Drever (1962), Upchurch & Mason (1962), Sund (1964) and Upchurch et al (1966). The results obtained usually showed a high degree of correlation between adsorption and the organic matter content of soils, with decreasing 186 0.…”

A glasshouse experiment was performed in which linuron was added to five Norwegian soils. Chemical residue analysis and bioassay tests showed that the rate of decomposition varied for the different soils and that the linuron content which produced a reduction in growth of ryegrass seedlings varied with soil type. No leaching into the lower layers occurred. An initial depression in the numbers of bacteria and fungi present in the soils was observed, but the populations later recovered. Decomposition du linuron dans differents solsResume. Dans un essai r^alis6 en serre, du linuron a 6t6 ajout^ a cinq sols norv^giens. Les analyses chimiques et les essais biologiques ont montr6 que le taux de decomposition varie dans les differents sols et que la quantity de linuron qui provoque une reduction de croissance de plantules de ray-grass varie selon le type de sol. II n'a pas 6t6 constat6 d'entrainement du produit dans les couches profondes du sol. Une diminution du nombre de bact^ries et de champignons presents dans les sols fut observte au d6but, mais les populations se r6tablirent par la suite. Abbau von Linuron in verschiedenen BodenZusammenfassung. In einem Gewachshausversuch wurden funf norwegische Boden mit Linuron behandelt. Chemische Ruckstandsanalyse und Bioteste zeigten, dass die Abbaugeschwindigkeit und der Linurongehalt, der bei Weidelgraskeimpflanzen Wachstumsbeeinflussungen verursachte, je nach Bodenart verschieden waren. Einwaschung in tiefere Bodenschichten erfolgte nicht. Eine augenblickliche Depression der Bakterien-und Pilzzahl in den Boden konnte beobachtet werden, doch erholten sich die Populationen spater wieder.

“…hieraciifolius, is a weed in the Pacific region (see Section 4) and central Europe (Belcher 1956;Voss 1996). It has also become a serious agricultural weed in Hawaii, invading sugar cane (Saccharum officinarum L.) plantations in that state (Hanson 1962;Sund 1964). Haselwood and Motter (1966) stated that, in Hawaii, it was, ''One of the most abundant weeds in moist cultivated areas; also a weed in pastures and rangelands.''…”

2012. The Biology of Canadian weeds. 150 Erechtites hieraciifolius (L.) Raf. ex DC. Can. J. Plant Sci. 92: 729Á746.Erechtites hieraciifolius, American burnweed, is a herbaceous annual in the Asteraceae native to forest zones of eastern North America, but introduced to parts of Europe and the Pacific region. Confusion sometimes arises in distinguishing it from other weedy rayless composites in Canada, such as Senecio vulgaris (common groundsel) and Conyza canadensis (Canada fleabane). A pioneer therophyte species of forest zones, it occurs in large numbers when associated with major disturbances such as forest fires, but is also common in areas of smaller scale disturbance such as shores, forest edges and wind-throws. Soil conditions may vary greatly in nutrient content, moisture content, pH and salinity. In Canada, it is generally considered a minor garden and agricultural weed. It is most common in crops such as lowbush blueberry (Vaccinium spp.), cranberry (Vaccinium macrocarpon), strawberry (Fragaria)ananassa) and vegetable crops; however, it occasionally occurs in other field and forage crops. Impacts include a variety of problems contributing to increased production costs or crop yield losses, including herbicide resistance, resource competition, and as a reservoir harbouring crop pathogens. It has been valued as a medicinal herb for treating a variety of ailments. Populations may grow rapidly in response to disturbances typical of managed landscapes, but E. hieraciifolius can usually be effectively controlled by chemical, cultural or manual weed control tactics.Darbyshire, S. J., Francis, A., DiTommaso, A. et Clements, D. R. 2012. La biologie des mauvaises herbes au Canada. 150 Erechtites hieraciifolius (L.) Raf. ex DC. Can. J. Plant Sci. 92: 729Á746. L'e´rechtite a`feuilles d'e´pervie`re (Erechtites hieraciifolius) est une herbace´e annuelle de la famille des Aste´race´es indige`ne aux re´gions forestie`res de l'est de l'Ame´rique du Nord, mais qui a e´te´introduite dans certaines parties de l'Europe et du Pacifique. On la confond parfois a`d'autres adventices a`rayons courts de la famille des Compose´es qui poussent au Canada tels le se´nec¸on vulgaire (Senecio vulgaris) et la vergette du Canada (Conyza canadensis). Espe`ce pionnie`re the´rophyte, on en retrouve de grand peuplements aux endroits qui ont subi de profondes perturbations comme un feu de foreˆt, cependant l'espe`ce colonise souvent des zones plus restreintes comme les rivages, la lisie`re des boise´s et les chablis. Les conditions du sol peuvent varier conside´rablement quant a`la concentration d'e´le´ments nutritifs, la teneur en eau, le pH et la salinite´. Au Canada, on la conside`re ge´ne´ralement comme une adventice secondaire dans les jardins et les champs. L'e´rechtite a`feuilles d'e´pervie`re se rencontre le plus souvent dans les cultures comme le bleuet nain (Vaccinium spp.), la canneberge (Vaccinium macrocarpon), la fraise (Fragaria)ananassa) et les plantes maraıˆche`res, cependant, on la de´couvre a`l'occasion dans d'autres grandes ...
