    Notes: The relative susceptibility of Digitaria sanguinalis (L.) Scop, (large crabgrass), Echinochloa crus-galli (L.) Beauv. (barn-yardgrass), Eriochloa villosa (Thumb.) Kunth. (hairy cup-grass), Setaria faberi Herrm. (giant foxtail), Setaria lutescens (Weigel) Hubb. (yellow foxtail), Setaria viridis (L.) Beauv. (green foxtail) and Setaria viridis var. robusta-purpurea Schreiber (robust-purple foxtail) to alachlor, atrazine, butylate and cyanazine was studied under glasshouse conditions. Hairy cupgrass was the least susceptible to the herbicides tested, of which alachlor appeared to be the most effective. Large crabgrass was controlled by alachlor, butylate and cyanazine at all of the rates tested, but by atrazine only at rates above 0–56 kg/ha. All four herbicides provided acceptable control for barnyardgrass, giant foxtail, green foxtail, robust-purple foxtail, and yellow foxtail. The susceptibility of the grasses to cyanazine and alachlor was correlated with seed size. Alachlor was more effective in controlling green foxtail and hairy cupgrass when applied to the soil surface before emergence than when incorporated into the soil prior to sowing.Sensibility de sept graminées annuelles à divers herbicidesLa sensibilité relative des espéces suivantes: Eriochloa villosa (Thumb,) Kunth. Echinochloa crus-galli (L.) Beauv. (panic). Digitaria sanguinalis (L.) Scop, (digitaire), Setaria faberi Herrm, (sétaire). Setaria viridis (L.) Beauv., Seiaria viridis var. robusla-purpurea Schreiber ct Seiaria lutescens (Weigel) Hubb., (sétaires) a étéétudiéé en serre. vis-d-vis de I'atrazine. de la cyanazine, du butylate et de I'alachlore. Eriochloa villosa a été I'espéce la moins sensible aux herbicides essayds parmi lesquels I'alachlore s'est montré le plus efficace. La digitaire a été maitrisé par I'alachlore, le butylate et la cyanazine k toutes les doses essayees, mais pour I'atra-zine. seulement à des doses supérieures à 0.56 kg/ha. Ces quater herbicides ont donne des resultats acceptables contre le panic, et les sétaires (S. faberi, S. viridis, S. viridis var. robusta-purpurea, S. lutescens). La sensibilité des graminées à la cyanazine et à I'alachlore fut en corrélation avec la taille des semences. L'alachtore s'est montré plus efficace contre la sétaire S. viridis var. robusta-purpurea ct contre l'Eriochloa villosa quand il a été appliqué sur la surface du sol avant la levée que lorsqu'il a éié incorporé au sol avant le semis.Die Empfindlichkeit von sieben einjährigen Gräsern gegenüber Herbiziden.Es wurde die relative Empfindlichkeit von Digitaria sanguinalis (L.) Scop., Echinochloa erus-galli (L.) Beauv., Eriochloa villosa (Thumb.) Kunth-, Setaria faberi Herrm., Setaria lutescens (Weigel) Hubb., Setaria viridis (L.) Beauv. und Setaria viridis var. robusta-purpurea Schreiber gegenuber Atrazin, Cyanazin, Butylat und Alachlor unter Gewächs-hausbedingungen untersucht. Eriochloa him war gegenúber den gepruften Herbiziden am wenigsten empfindlich, Alachlor scliien die beste Wirkung zu haben. Digiiaria sanguinalis wurde durch Alachkir. Butylat und Cyanazin bei alien gepruften Aiifwandmengen bekampft, durch Atrazin aber nur bei Aufwandmengen ilber 0.56 kg/ha. Alte vier Herbizide ergaben eine brauchbare Bekampfung von Echinochloa crus-galli, Seiaria Jabcri, Seiaria viridis. Setaria viridis var. robusta-purpurea und Setaria luiescens. Die Emptindlichkeit der Gräser gegenüber Cyanazin und Alachlor stand in Beziehung zur Samengrösse. Alachlor bekämpfte Seiaria viridis und Erioehloa villosa im Vor-auflaufverfahren besser als im Vorsaatverfahren mit Ein-arbeitung.

    Notes: Growth chamber studies were conducted to investigate the effects of alachor (2-choloro-2′,6′-diethyl-N- (methoxymethyl) acetanilide) on emerging seedlings of maize (Zea mays L.) planted 2.5 and 8.0 cm deep in a Plano silt loam soil. Alachlor was localized in the shoot zone, in the root zone, and in the shoot and root zones. Four days after emergence, seedlings were harvested and total shoot and root lengths used as measures of herbicidal effectiveness. The herbicide applied at a rate of 2.5 kg/ha caused a severe reduction in seedling height when placed in the shoot zone of seeds planted at the shallow depth. This injury was prevented when seeds were planted at the deeper level. When alachlor was placed in the root zone, there was no inhibition of shoot growth. When both shoot and root zones were exposed to the herbicide, severe growth inhibition again occurred. Roots were less sensitive to alachlor. A simple technique involving use of sand and activated charcoal barriers to effectively separate the shoot and root zones is described.

    Notes: The effectiveness of 122 herbicides in inhibiting growth of buds from single-node sections of couch (Agropyron repens (L.) Beauv.) rhizomes was evaluated under glasshouse conditions. Treatments were made by planting twenty-five couch rhizome segments in washed silica sand and watering them with nutrient solution containing from 10−2 to 10−8 M concentrations of the herbicides. Final evaluations were made 21 days after planting. At 10−5 M or lower concentrations, nineteen herbicides inhibited couch bud growth to less than 5 % of that in the untreated cultures. This concentration is approximately 0–28 kg/ha calculated on a 15-cm plough-slice basis. Herbicide groups showing the greatest inhibition of quackgrass rhizomes were the anilides and amides, carba-mates, and toluidines. Overall, pronamide (3,5-dichloro-N-(1,1-dimethylpropynyl)-benzamide) demonstrated the greatest activity. Many of the herbicides shown to be effective in this study do not generally control quackgrass under field conditions. Their lower activity in the field may be due to excessive decomposition, soil-herbicide interactions, or lack of rhizome exposure to the herbicides. Some herbicides which provide couch control under field conditions were not effective in this study. The reduced effectiveness of these chemicals under the conditions tested probably occurred because the herbicides were active only when applied post-emergence, because the primary action mechanisms were on processes other than bud development, or because the observation period was too short to detect complete results.Influence des herbicides sur le developpement des bourgeons du chiendentL'activité inhibitrice de la croissance des bourgeons de fragments de rhizomes de chiendent (Agropyron repens (L.) Beauv.) comportant un seul noeud, a étéévaluée en serre pour 122 herbicides. Les traitements ont été effectués en plantant 25 fragments de rhizome de chiendent dans un sable de silice Iavé et en leur apportant une solution nutritive contenant les herbicides k des concentrations allant de 10−2à 10−8 M. Les évaluations finales ont été faites 21 jours aprés la plantation. A la concentration a 10−5 M ou a des concentrations plus faibles, dix-neuf herbicides inhibérent la croissance des bourgeons de chiendent jusqu'a moins de 5 % de celle des cultures non traitées. Cette concentration correspond approximativement k un traitement à 0,28 kg/ha calculé sur la base d'un labour à 15 cm. Les groupes d'her-bicides manifestant la plus forte inhibition des rhizomes de chiendent furent les anilides, les amides, les carbamates et les toluidines. Le plus actif fut la pronamide (3,5-dichloro-N-(1,1-dimothylpropynil)-benzamide). Beaucoup des herbicides qui se montrerent efficaces dans cette étude ne l'etaient pas contre le chiendent au champ. Leur activité plus faible au champ peut été due k une decomposition excessive, k des interactions sol-herbicide, ou au défaut de contact entre les rhizomes et les herbicides. Quelques herbicides qui s'avfirent efficaces au champ contre le chiendent ne l'ont pas été dans cet essai. La réduction d'efficacité des produits dans les conditions de essaisest probablement manifest Se en raison du fait que les herbicides furent actifs seulement en traitements de post-levée, parce que les mocanismes d'action primaire s'exerecérent sur des processus autres que le développement des bourgeons, ou parce que la période d'observation fut trop courte pour detecter des résultats complets.Einfluss von Herbiziden auf die Knospenenlwicklung bei der QueckeEs wurde die Wirkung von 122 Herbiziden auf die Hemmung des Knospenwachstums von Rhizomabschnitten der Quecke (Agropyron repens (L.) Beauv.) mit jeweils einem Nodium, unter Gewachshausbedingungen untersucht. Die Behand-lungen wurden folgendermassendurchgefuhrt: 25 Abschnitte von Queckenrhizomen wurden in gewaschenen Quarzsand gepfianzt und mit Nahrlosung gegossen, die Herbizid in 10−2 bis 10−8 M Konzentration enthielt. Die endgultige Aus-wertungerfolgte 21 Tage nach dem Pflanzen. Bei 10−5 M oder niedrigeren Konzentrationen hemmten 19 Herbizide das Wachstum der Queckenknospen um weniger als 5% im Vergleich zu Unbehandelt. Diese Konzentration entspricht etwa einer Aufwandmenge von 028 kg/ha bezogen auf 15 cm Pfiugtiefe. Die grossteHemmwirkung gegenuber den Queckenrhizomen zeigten die Herbizide aus der Gruppe der Anilide, Amide, Carbamate und Toluidine. Insgesamt wies Pronamid (3,5-Dichlor-N-(1,1-dimethylpropinyl)-benzamid) die grosste Aktivitat auf. Viele der Herbizide, die unter den Versuchs-bedingungen wirksam waren, bekSaAmpfen die Quecke im Freiland gewöhnlich nicht. Die geringere Wirksamkeit dieser Herbizide im Freiland kann auf ubermessigen Abbau, auf Boden-Herbizide-Wechselbeziehungen oder auf fehlenden Kontakt des Rhizoms mit dem Herbizid zuruckzufuhren sein. Andererseits waren einige Herbizide, die eine Be-kampfung der Quecke unter Freilandbedingungen gewähr-leisten, in diesem Versuch nicht wirksam. Die verringerte Wirksamkeit diser Verbindungen unter den hier herrschenden Bedingungen, kann darauf zuruckgefuhrt werden, dass die Herbizide nur wirksam sind, wenn sie im Nachauflauf eingesetzt werden weil die primaren Wirkungsmechanismen an andere Prozesse als die Knospenentwicklung gebunden sind, Oder weil der Beobachtungszeitraum zu kurz war, um zu einer endgultigen Aussage zu gelangen.
