Abstract Spodoptera frugiperda (J. E. Smith, 1797) is a polyphagous pest of global relevance due to the damage it inflicts on agricultural crops. In South American countries, this species one principal pests maize and cotton. Currently, S. also emerging as an important soybeans winter cereals in Brazil. Chemical control main tactics against frugiperda, even though resistance numerous modes acti...

Hyphal networks, resulting from mutualistic symbiotic associations between plants and arbuscular mycorrhizal fungi (AMF), improve plant growth nutrition by enhancing root access to a significantly larger soil surface area, which increases nutrient availability translocation within the plant-host. Considering limitations imposed low commonly found in highly weathered soils of Brazil, positive ef...

Spodoptera frugiperda, est un ravageur exotique du maïs qui menace la sécurité alimentaire en Afrique subsaharienne général et Togo particulier. Dans le but de contribuer à une gestion durable ravageur, présente étude vise évaluer l’effet des associations maïs– soja maïs-manioc sur dynamique population les dégâts ravageur. Les traitements (culture pure maïs, soja, manioc, association maïs-soja,...

This flash examines trends in market participation by smallholder farmers in rural central and northern Mozambique between 2008, when prices of many commodities rose to previously unseen levels, and 2011. Using panel data for 2008 and 2011, the analysis describes marketing dynamics – entry, exit, and persistence of participation, and the trends in marketing intensity associated with those dynam...

Efforts to anticipate how climate change will affect future food availability can benefit from understanding the impacts of changes to date. We found that in the cropping regions and growing seasons of most countries, with the important exception of the United States, temperature trends from 1980 to 2008 exceeded one standard deviation of historic year-to-year variability. Models that link yiel...

A chronic feeding study to evaluate the safety of genetically modified glyphosate-tolerant soybeans (GM soybeans) was conducted using F344 DuCrj rats. The rats were fed diet containing GM soybeans or Non-GM soybeans at the concentration of 30% in basal diet. Non-GM soybeans were a closely related strain to the GM soybeans. These two diets were adjusted to an identical nutrient level. In this st...

Abstract The data sources for the study were results of a continuous agrochemical (for 3 cycles) and soil erosion survey soils, as well official statistical data. period was characterized by an increase in content organic matter 0.35%, alkaline hydrolyzable nitrogen 20 mg/kg, pH acidity degree 0.15 units, reduction amount medium acidic soils 16.4%. It found that on poorly eroded decreases 0.4%,...

BACKGROUND Allergic reactions after ingestion of fermented soybeans have rarely been reported. Fermented soybeans were recently reported to be a causative food of IgE-mediated, late-onset anaphylaxis without early phase responses. The objectives of our study are to clarify the clinical and laboratory features and to characterize the allergens in allergy due to fermented soybeans. METHODS Seve...

Global adoption of transgenic crops reached 67.7 million hectares in 2003 from 2.8 million in 1996. Delivery has occurred almost entirely through the private sector and adoption has been rapid in areas where the crops addressed serious production constraints and where farmers had access to the new technologies. Three countries (USA, Argentina and Canada), three crops (soybean, cotton and maize)...
