Recycling of entomopathogenic nematodes in coffee crop (Coffea spp.) growing soils in Buey Arriba

Rodríguez, M.G., Centro Nacional de Sanidad Agropecuaria et al. [ene-abr2011]

The coffee berry borer (CBB) (Hypothenemus hampei Ferrari) is one of the most important pests of the coffee crop in the world. In Cuba it has been the key pest since the middle of the last decade of the twentieth century. For its management, some biological control agents (entomopathogens and invertebrates) have been evaluated under field conditions in different areas. In those cases where ent ...

Los restos agroindustriales constituyen un grave problema a nivel mundial. Generalmente su gestión se restringe al vertido y solo en casos concretos se les da uso productivo, transformándolos en coproductos. En la actualidad, se proponen alternativas para su gestión, evaluando su eficacia como biodesinfectantes para el manejo de organismos plaga, sobre todo los que se generan en mayor cantidad ...

To know the biodiversity of plant feeding mites is very important in order to obtain information about the harmful species in the agroecosistems. Tuckerelid mites are frequent on the citric fruits; however, in the last years, they have been collected on other plants in several countries. It has not been proven that they are biological vectors of diseases, or that they cause serious dysfunction ...

Catálogo de ácaros interceptados en la provincia de Granma

Labrada, Y., Laboratorio Provincial de Sanidad Vegetal et al. [jun2011]

Mites intercepted in Granma province since year 1980 to 2011 are given in this work. There were determined 56 species contained in 12 families and 33 genera, collected in 62 species of host plants. Inside the intercepted species three constitute new pest reports for mite fauna of the province, and one is new predator for Cuba. The detected species were enumerated and orderly alphabetically for ...

Supervivencia de Ralstonia solanacearum en suelo y tejido de plantas de banano en Urabá, Colombia

Obregón, M., Centro de Investigaciones del Banano. Augura et al. [jun2011]

Moko disease caused by the bacterium Ralstonia solanacearum race 2 is one of the most restraining phytosanitary problems to deal with banana and plantain production in Colombia. Infected areas must be carefully controlled to prevent dispersal. Control measures include eradication of both infected and apparently non-infected plant within a 5 meters radius around the infected plant treated with ...

Arbuscular mycorrhizae fungi (AMF) improve plants nutrition. However, the effect of new pesticides on agro-ecosystems is still unknown. Currently crops protection is done generally by chemical methods applied over seeds. Thus, the percent of mycorrhizal colonisation, visual density and the estimation of mycelium micomass endophytic to roots were determined, in order to find whether existence o ...

Bacteria of genus Bacillus were isolated from soil and their antagonistic activity in vitro against the fungus Macrophomina phaseolina was evaluated in different culture media. The culture media tested were Potato-Dextrose-Agar (PDA), Nutrient Agar (NA), Trypticase-Soy-Agar (TSA) and the mixture NA-PDA (2:1). M. phaseolina radial growth was 34.7 ± 2.5 mm in PDA, 29.0 ± 1.0 mm in AN:PDA, 27.3 ± ...

Actividad antifúngica in vitro de extractos de Navisporus floccosus y Ganoderma sp. contra hongos fitopatógenos

Palacios, J.R., Instituto de Investigaciones de Sanidad Vegetal et al. [jun2011]

Basidiomycete fungi produce some bioactive compounds with antibacterial, antiviral and antifungal activities. This capacity has facilitated their use in agriculture and medicine, recently. Antifungal activity evaluation of Navisporus floccosus (Bres), Ryvarden and Ganoderma sp. extracts against Phytophthora nicotianae Breda de Haan and Curvularia clavata B. L. Jain was the purpose of this work ...
