Climate effect on Avena fatua field emergence dynamics: a 38-year experiment in the Semiarid Pampean Region of Argentina
Renzi Pugni, Juan Pablo; Traversa, Guadalupe; Vigna, Mario Raul; Chantre Balacca, Guillermo Ruben (Wiley, 2022-02)Climate events modulate weed population dynamics mainly by influencing field seedling emergence patterns. Field experiments aiming to study the influence of climate on the early-stage establishment of weeds are of utmost ... -
Control biológico de Carduus nutans auct. non L. (syn Carduus thoermeri Weinm) con Rhinocyllus conicus
Vigna, Mario Raul; Carretto Nocolo, Luis Miguel (Departamento de Agronomía, Universidad Nacional del Sur, 2016-12)Carduus nutans es una planta anual, nace a fines de marzo y forma la roseta durante el invierno, desarrolla el tallo florífero a principios de primavera y florece a mediados y fines de la misma. -
A flexible and practical approach for real-time weed emergence prediction based on Artificial Neural Networks
Chantre Balacca, Guillermo Ruben; Vigna, Mario Raul; Renzi Pugni, Juan Pablo; Blanco, Anibal Manuel (2018-06)Most popular emergence prediction models require species-specific population-based parameters to modulate thermal/hydrothermal accumulation. Such parameters are frequently unknown and difficult to estimate. Moreover, such ... -
Impact of Imazamox and Imazapyr Carryover on Wheat, Barley, and Oat
Scursoni, Julio Alejandro; Montoya, Jorgelina Ceferina; Vigna, Mario Raul; Gigon, Ramon; Istilart, Carolina Maria; Renzi Pugni, Juan Pablo; Lopez, Ricardo; Porfiri, Carolina (2017-12)Imazapyr and imazamox are frequently applied postemergence to control grass and broadleaf weeds in imidazolinone-resistant sunflower in Argentina. Herbicide carryover to rotational crops represents a disadvantage of these ... -
Manejo de malezas en los sistemas agriculturizados
Vigna, Mario Raul (2014-12)Cada sistema tiene sus problemas y en función de ello hay que trabajarlos y sobre todo estudiarlos, teniendo en cuenta siempre el contexto que se producen. En nuestro país y el resto de América, el problema de las malezas ... -
Modeling Avena fatua seedling emergence dynamics: an artificial neural network approach
Chantre Balacca, Guillermo Ruben; Blanco, Anibal Manuel; Lodovichi, Mariela Victoria; Bandoni, Jose Alberto; Sabbatini, Mario Ricardo; Lopez, Ricardo Luis; Vigna, Mario Raul; Gigon, Ramon (Elsevier, 2012-10)Avena fatua is an invasive weed of the semiarid region of Argentina. Seedling emergence patterns are very irregular along the season showing a great year-to-year variability mainly due to a highly unpredictable precipitation ... -
Modeling seed dormancy release and germination for predicting Avena fatua L. field emergence: A genetic algorithm approach
Blanco, Anibal Manuel; Chantre Balacca, Guillermo Ruben; Lodovichi, Mariela Victoria; Bandoni, Jose Alberto; Lopez, Ricardo Luis; Vigna, Mario Raul; Gigon, Ramon; Sabbatini, Mario Ricardo (2014-01-24)Avena fatua is a cosmopolite weed species which produces severe yield losses in small-grain production systems in temperate and semiarid climates. In the semiarid region of Argentina, A. fatua field emergence patterns show ... -
Operational planning of herbicide-based weed management
Lodovichi, Mariela Victoria; Blanco, Anibal Manuel; Chantre Balacca, Guillermo Ruben; Bandoni, Jose Alberto; Sabbatini, Mario Ricardo; Vigna, Mario Raul; Lopez, Ricardo Luis; Gigon, Ramon (2013-10)Weeds cause crop yield loss due to competition, interfere with agricultural activities and reduce grain quality due to seed contamination. Among the numerous methods for weed control, the use of herbicides is the most ... -
Poblaciones de Lolium sp resistentes a cletodim en el sur de Buenos Aires
