Potatoes (Solanum tuberosum L.) are produced in all Canadian provinces, and interest has increased in the use of non-synthetic chemicals and organic techniques to provide weed control. Acetic acid has been suggested as a chemical that could potentially provide weed control in potato production. We examined glacial acetic acid and Ecoclear (30% acetic acid, 1.0% naptha solvent and 1.0% trimethyl benzene) for effectiveness in controlling weeds in potatoes when applied in a 30-cm-wide band over the potato row as well as their effect on potato yield components in three experiments repeated over 2 yr. The effects of time of application and volume of application were also examined. Glacial acetic acid at 10% concentration did not injure potato foliage, but at 20 and 30% concentration it injured emerged potato foliage. A concentration of 20% acetic acid was needed to provide acceptable weed control levels of lambs-quarters, corn spurry and wild buckwheat. Marketable yield was reduced by 20 and 30% acetic acid to below the standard herbicide treatment. Sequential applications of acetic acid at concentrations of 10, 20 or 30%, applied 7-10 d apart, caused slightly greater injury and yield was 10 to 15% less than in the single application. Ecoclear applied to emerged weeds and before potato emergence did not injure potato foliage, but when applied post-emergence it caused severe, but short lived, potato injury. Ecoclear gave greater than 80% control of lambs-quarters, corn spurry and wild radish. Potato marketable yield was comparable with that achieved with a herbicide and was reduced only in one year by Ecoclear applied post-emergence. Weed control was 18% or less when Ecoclear was applied at 200 L ha-1, 54 to 74% when applied at 400 L ha-1 and 91 to 95% when applied at 800 L ha-1 volume of application.

The effect of hilling methods on weed control in potatoes (Solanum tuberosum L.) was studied in association with the effect of herbicides and cultivars. Without herbicides, hilling at emergence gave the best control. However, late-germinating weeds were not controlled. When herbicides were used, no difference was noted in weed control due to hilling methods. Hilling at tuber set needed to be preceded by a herbicide. This method gave earlier development of tubers. Variations in yield were more closely associated to top weight than to weed density. Linuron (3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea) was more effective than prometryne (2,4 bis (isopropylamino)-6-(methylthio)-s-triazine). There were no significant differences in weed control between cultivars. Time of hilling potatoes should not be determined according to its influence on weed control, but rather according to its influence on the vegetative growth of the potato plant.

In this paper the results of efficiency of combined application of six herbicides in weed control in potato were presented. The study was done during 2007 and 2008 in Kolašin, on acid brown soil, at an altitude of about 900 m. In the experiment the following herbicides were examined: S-metalachlor, Bentazone, Acetohlor, Flurochloridone, Metribuzin and Dimetenamid-P. The study was conducted in the Kennebec variety crop. All applied herbicides had satisfactory effect in decreasing number and biomass of weeds. As the most effective variants in two-year average, Sencor 70 WP and Genius were expressed (95 and 94% for the number and 92 and 88.8% for weed biomass) and the weakest effect had combination of Dual Gold 960 EC + Basagran (82.3; 69.4, respectively). In all investigated combinations of herbicides significantly higher tuber yield was achieved comparing to the control. The highest yield of tubers was measured in variant where Acenit 800 EC was applied - 33 t ha-1, while the lowest yield had the control variant - 18.4 t ha-1.

Objetivo: Establecer una línea base como fundamento para la intervención e inducción de innovaciones a través de escuelas de campo y planes de negocios. Diseño/metodología/aproximación: El estudio se desarrolló en San José del Carmen, San Cristóbal de Las Casas, Chiapas, México. Se elaboró una encuesta como instrumento para recabar en campo información de familias de la localidad con la finalidad de conocer su situación actual. La localidad de trabajo se eligió utilizando como criterio las poblaciones que se encuentran dentro de Cruzada Nacional contra el hambre y en la clasificación de la pobreza extrema Resultados: La localidad de San José del Carmen es considerada como de alta marginación, la población es bilingüe, su principal lengua es el Tzotzil, el nivel de estudios promedio es hasta el tercer año de primaria, las principales actividades productivas son la siembra de maíz (Zea mays L.), frijol (Phaseolus vulgaris L.), papa (Solanum tuberosum L.) y haba (Vicia faba L.) que son utilizadas principalmente para autoconsumo.  No cuentan con agua potable ya que su sistema es a través de la recaudación de agua de lluvia o a través de un jagüey. Sus principales actividades económicas son la albañilería por parte de los hombres, y venta de productos, tales como el pozol (bebida energética a base de maíz y cacao (Theobroma cacao L.), tostadas y algunos vegetales por parte de las mujeres. Las tostadas son producidas en forma artesanal con un proceso de doble nixtamalización y vendida en bolsas de 20 tostadas cada una, a un costo de MX$10.00 en los mercados de San Cristóbal de las Casas, una a dos veces por semana alrededor de 40 bolsas por día de venta. Limitaciones del estudio/implicaciones: La afiliación zapatista de alguno de los pobladores y el hecho de que algunos habitantes no hablen español, fueron factores que limitaron desarrollar al 100% el estudio; sin embargo, se considera que se tienen los elementos necesarios para establecer la línea base de la situación de San José del Carmen. Conclusiones: El diagnóstico servirá como una herramienta para establecer una intervención a través de innovaciones y planes de negocios en la comunidad de estudio. Los pobladores cuentan con herramientas necesarias para obtener nuevos conocimientos que ayuden a un desarrollo de su producción. El idioma no deberá de ser una limitante para ello.
