Analysis of nutrient deficiencies affecting in vitro growth and development of Eucalyptus dunnii Maiden
(2018-06)Although basal medium optimization is a key factor in the success of tissue culture, its mineral composition is frequently disregarded when optimizing in vitro propagation protocols. A previous work on Eucalyptus dunnii ... -
Caracterización de aislamientos de moho verde (Penicillium digitatum) resistentes al fungicida pirimetanil en la región citrícola del río Uruguay
(2018-08)El uso continuado de los fungicidas tiabendazol e imazalil en los empaques citrícolas de la región del río Uruguay ha llevado a la selección y proliferación de aislamientos de moho verde resistentes; este hongo es la ... -
Proteomic and metabolomic approaches unveil relevant biochemical changes in carbohydrate and cell wall metabolisms of two blueberry (Vaccinium corymbosum) varieties with different quality attributes
(Elsevier, 2018-12)Quality maintenance in rapidly decaying fruit such as blueberries (Vaccinium corymbosum) is of essential importance to guarantee the economic success of the crop. Fruit quality is a multifaceted subject that encompasses ... -
Interactions between mineral fertilization and arbuscular mycorrhizal fungi improve nursery growth and drought tolerance of Prosopis alba seedlings
(Springer, 2019-02-28)Prosopis alba Griseb. (algarrobo blanco) is an important tree legume in semiarid regions of South America. Under field conditions, their seedlings are subjected to a wide range of environmental conditions that might produce ... -
Contribution of predation to the biological control of a key herbivorous pest in citrus agroecosystems
(Wiley, 2019-03-21)Biological control has traditionally simplified the view of trophic relationships between herbivorous pests and their natural enemies in agriculture. The success or failure of this pest management strategy is still mainly ... -
Life history traits of the coccinellids Scymnus subvillosus and S. interruptus on their prey Aphis spiraecola and A. gossypii: Implications for biological control of aphids in clementine citrus
(Elsevier, 2019-05)Predator-prey interactions are not static, but spatially and temporally dynamic. In addition to the climatic conditions and the prey density, the dynamics of predator populations may be influenced by the suitability of ... -
Transición del manejo de plagas convencional hacia el agroecológico mediante la transferencia de técnicas de control integrado de plagas en tomate bajo cubierta en Concordia - Provincia de Entre Ríos, Argentina = The transition from chemical pest control to biological pest management through the transfer of integrated pest management techniques in greenhouse tomatoes in Concordia - Province of Entre Ríos, Argentina
(Facultad de Ciencias Agronómicas, Universidad de Tarapacá, Chile, 2019-09)A lo largo del período 2015 - 2017 se dio comienzo a una transición del manejo convencional de plagas, es decir, basado únicamente en la aplicación de productos químicos sintéticos de amplio espectro, a un manejo agroecológico ... -
A global synthesis reveals biodiversity-mediated benefits for crop production
