Downy mildew (DM) of sunflower is a devastating disease caused by Plasmopara halstedii (Farl.) Berl. and de Toni. In Argentina, the prevalence and incidence of DM has increased in the last decade. The present study: i) compiles information from private and public organisms to assess the race spectrum of DM and its evolution during the last three de...

Las enfermedades fúngicas causan pérdidas de rendimiento y de calidad en los granos de cebada, especialmente en las cebadas con destino a maltería. Existe un número acotado de variedades de cebada, las cuales en mayor o menor medida son susceptibles a alguna de las principales enfermedades que afectan a este cultivo (Moreyra y col., 2020). En el co...

Oxathiapiprolin is an oomicide with a mechanism of action not previously used in Argentina. The objective was to determine the baseline sensitivity of Plasmopara halstedii isolates to oxathiapiprolin applied to sunflower seeds. Materials: isolates from Buenos Aires (5), Santa Fe (11) and Chaco (2), susceptible hybrid seeds DK4065. Treatments: 0 (Co...

Metalaxil-m ha sido históricamente el ingrediente activo más efectivo para el control de Plasmopara halstedii en girasol. Existen registros de pérdidas de sensibilidad de diferentes aislamientos en la Argentina. El objetivo fue determinar la sensibilidad de aislamientos de Plasmopara halstedii a metalaxil-m de regiones productoras de girasol de Arg...

Due to the increase in pesticide detection in groundwater and other environmental components, some indicators, such as the attenuation factor (AF) and the environmental impact quotient (EIQ), have been proposed to determine potential pesticide contamination. Thus, it is possible to select pest management strategies in order to minimize the risk of...

Terrestrial isopods (approximately 3700 known species in the world) are encountered in temperate and tropical regions, from the seashore to high altitudes and from floodplain forests to deserts. They are known to contribute to soil biodiversity. Environmental factors and anthropogenic actions, particularly land use changes such as primarily agricul...

La aplicación de fungicidas foliares es la principal estrategia de manejo en las variedades de trigo susceptibles a la roya amarilla (RA). El objetivo fue evaluar el efecto de la incorporación de carboxamidas a las mezclas dobles de fungicidas sobre el control de RA en trigo. El ensayo se realizó en un lote de trigo (variedad Algarrobo, Don Mario)...

La función de daño es el parámetro fundamental del modelo de Nivel de Daño Económico (NDE). Los objetivos fueron: evaluar los perjuicios de Armadillidium vulgare en el cultivo de girasol y determinar la función de daño en el cultivo para poder estimar el NDE. Las evaluaciones se realizaron en tres ciclos agrícolas según un diseño en bloques complet...

Damage function is the parameter of Economic Injury Level model (EIL). The aims were: evaluate the injury of Armadillidium vulgare in the sunflower crop and determine the damage function in the crop for estimating EIL. The study was done in three agricultural cycles. Assessments were conducted in three agricultural cycles according randomized compl...

In Argentina, two tillage systems are used, conventional tillage (CT) and no-till (NT). The aim was to determine the ground-dwelling macrofauna taxa and compare the impacts of both NT and CT on their activity density. Samples were taken within wheat (Triticum aestivum L.) (August-December) and maize (Zea mays L.) (November-April) crop fields under...

Oil seed rape (Brassica napus) under No Tillage (NT) represents an alternative in the current crop rotationsystems. Deroceras reticulatum “gray slug” is a one of the present pest in this crop under NT. The aim of thisstudy was to evaluate combined action bait and liquid Metaldehyde as an alternative strategy control of the specie. Laboratory and fi...

La colza (Brassica napus, B. campestris) en siembra directa (SD) representa una alternativa en los sistemas de rotación actuales. Armadillidium vulgare es una de las plagas principales de los cultivos en SD. El objetivo de este trabajo fue evaluar cebos de acción combinada como estrategia alternativa de control de dicha especie. Se realizaron ensay...

The studies of Armadillidium vulgare as pest are virtually null worldwide. However under no-tillage systems this species has found an adequate environment for its development and it has become an important pest in some crops in Argentina. It has been shown that the composition of vegetables affects the isopods biology. Our hypothesis was that soybe...

In the southeast of Buenos Aires Province, Argentina, Milax gagates (Draparnaud, 1801) causes reductions in yields of soybean, sunflower and oilseed rape under no tillage by damaging seeds and seedlings. Whilst there are some studies of the damage caused by M. gagates to sunflower and soybean crops, and the control of slugs in soybean, there is lit...

Soil degradation increased incessantly in the Pampas region of Argentina, due to the intensification of agricultural activities, when carried out with conventional tillage (CT) systems. No-tillage system was adopted as conservation practices by the farmers. The objectives of this study were: a) to determine the macrofauna taxa and their relative ab...

Management of the grey slug, Deroceras reticulatum (Müller) (Pulmonata: Stylommatophora), in Argentina, has been limited to the use of pelleted toxic baits containing metaldehyde. The most important molluscicides in the Argentinean market are Clartex (Rizobacter Argentina S.A.), Acay (Acay Agro S.R.L.) and Babotox (Huagro S.A.). The aim of this wor...

La siembra directa ha disminuido los riesgos de erosión del suelo pero ha favorecido el desarrollo de organismos como Deroceras reticulatum y D. laeve (Mollusca: Pulmonata: Limacidae). El objetivo del trabajo fue determinar los parámetros biológicos y el crecimiento de ambas especies a 12º y 20º C. La experiencia se inició con adultos reproductivos...

The marsh slug Deroceras laeve (Müller) (Pulmonata: Stylommatophora) was recently introduced into the southeast of the Buenos Aires Province of Argentina, and has become one of the main pests of cropping systems under no-tillage management. The growth, survival, and reproduction of D. laeve were monitored at 12°C and 20°C to determine the most appr...
