Glyphosate Use in Forest Plantations
(2010)Under Chilean conditions the lack of weed control at forest tree establishment results in an average of at least 60% less biomass accumulation during the first year of growth of radiate pine or eucaliptus, and glyphosate ... -
Evaluation Of Risk Factors In Agriculture: An Application Of The Analytical Hierarchical Process (AHP) Methodology
(2011)Risk in the agricultural sector has multiple dimensions or factors and prioritization of these can support decision making. On the other hand, knowing the importance of these risk factors for distinct agricultural activities ... -

Using penoxsulam ALS inhibitor as a broad-spectrum herbicide in Chilean rice
(2011)The continuously-flooded rice production system in Chile has selected highly competitive aquatic weeds selection capable ofreducing paddy yields by 25 to 50%. Penoxsulam is a broad-spectrum triazolopyrimidine (ALS inhibitor) ... -
Effects of physicochemical soil properties of five agricultural soils on herbicide soil adsorption and leaching
(2011)Once pesticides reach the soil, there are several factors that affect their soil behavior. To identify the principal soil and herbicide properties that control their adsorption and leaching, a study of five Chilean ... -
Adsorption and desorption variability of four herbicides used in paddy rice production
(2011-01)This investigation was performed to determine the effect of physicochemical soil properties on penoxsulam, molinate, bentazon, and MCPA adsorption-desorption processes. Four soils from Melozal (35° 43' S; 71° 41' W), Parral ... -
Water and sediment dynamics of penoxsulam and molinate in paddy fields: field and lysimeter studies
(2011-07-15)BACKGROUND: In Chile, rice is cultivated under water-seeded and continuously flooded conditions. Because herbicide dynamics in paddy fields and non-flooded fields is different, 3 year experiments were performed to study ... -
Simazine transport in undisturbed soils from a vineyard at the Casablanca valley, Chile
(2013-01-20)Simazine is a soil-active herbicide that has been applied worldwide in agricultural soils, being the second most commonly detected herbicide in groundwater and surface waters. Although its use has been restricted in many ... -
Competitive Strategies and Growth of Neighbouring Bromus valdivianus Phil. and Lolium perenne L. Plants Under Water Restriction
(2013-05)Often perennial pastures have to tolerate soil water restriction during summer, which can affect the relative abundance of the most desired species. In the south of Chile, Bromus valdivianus and Lolium perenne are preferred ... -
Quantifying effects of irrigation and soil water content on electricalpotentials in grapevines (Vitis vinifera) using multivariate statisticalmethods
(2014-05-20)Several studies have shown that physiological responses in plants, including fruit crops, are associated with changes in electrical potentials (EP), but it is often difficult to statistically quantify these responses. This ... -
Evaluation of sustainability and the impact of the agriculture styles of the chilean coastal dry lands
(2017)Agriculture has been progressing continuously, from the use of free natural resources to the fossil fuels as energy sources. Even though agriculture depends mainly on ecosystem resources and services, its development has ... -
Role of the spinal TrkB-NMDA receptor link in the BDNF-induced long-lasting mechanical hyperalgesia in the rat: A behavioural study
(2017)Background: Intrathecal/intracisternal BDNF in rodents produces longlasting hyperalgesia/allodynia, which implies BDNF plays a role in the establishment and maintenance of central sensitization. Both selfregeneration of ... -
Quercetin Prevents Diastolic Dysfunction Induced by a High-Cholesterol Diet: Role of Oxidative Stress and Bioenergetics in Hyperglycemic Rats
(2018)Alterations in cardiac energy metabolism play a key role in the pathogenesis of diabetic cardiomyopathy. Hypercholesterolemia associated with bioenergetic impairment and oxidative stress has not been well characterized in ... -
Reporte de Caso: Primer Caso de Pearsonema spp. en Felino Doméstico de Chile
(2018)En Chile no han sido reportados casos de Pearsonema spp (Capillaria spp) en caninos o felinos domésticos, sólo se han descrito en cánidos silvestres (Jiménez et al., 2012). En cuanto a la literatura internacional existen ... -
Aproximaciones a la deserción universitaria en Chile
(2018)La educación universitaria vespertina, en Chile, ha presentado en los últimos años, un acentuado crecimiento en su matrícula. Sin embargo, la interrupción de los estudios de quienes estudian en este horario de 19 a 23 horas ... -
Pyrrolizidine alkaloid toxicosis and hepatic encephalopathy in horses in Easter Island, Chile
(2018)A group of horses died in Easter Island following anorexia, weight loss and neurological signs. Similar cases have occurred since the introduction of a plant containing pirrolizidine alkaloid to the island. This study ... -
Determinación del Efecto de Tres Concetraciones de Aceite Esencial de Eucalipto, para el Control Ecológico de la Varroasis en Colmenas en Producción, en Los Molles, Región de Valparaíso, Chile
(2018)La varroasis es producida por ácaros de la especie Varroa destructor, un ectoparásito que desde hace décadas, ha generado graves problemas a la producción apícola nacional y mundial. El año 1992 se diagnosticó por primera ... -
High-Fat-Diet-Induced Obesity Produces Spontaneous Ventricular Arrhythmias and Increases the Activity of Ryanodine Receptors in Mice
(2018)Ventricular arrhythmias are a common cause of sudden cardiac death, and their occurrence is higher in obese subjects. Abnormal gating of ryanodine receptors (RyR2), the calcium release channels of the sarcoplasmic reticulum, ... -
