The global burden of pathogens and pests on major food crops

By Community Manager - Mar 08, 2019

Abstract: Crop pathogens and pests reduce the yield and quality of agricultural production. They cause substantial economic losses and reduce food security at household, national and global levels. Quantitative, standardized information on crop losses is difficult to compile and compare across crops, agroecosystems and regions. Here, we report on an expert-based assessment of crop health, and provide numerical estimates of yield losses on an individual pathogen and pest basis for five major crops globally and in food security hotspots. Our results document losses associated with 137 pathoge [...]

Lack of adverse effects in subchronic and chronic toxicity/carcinogenicity studies on the glyphosate-resistant genetically modified maize NK603 in Wistar Han RCC rats

By Community Manager - Mar 08, 2019

Abstract:  In 2012, a controversial study on the long-term toxicity of a Roundup herbicide and the glyphosate-tolerant genetically modified (GM) maize NK603 was published. The EC-funded G-TwYST research consortium tested the potential subchronic and chronic toxicity as well as the carcinogenicity of the glyphosate-resistant genetically modified maize NK603 by performing two 90-day feeding trials, one with GM maize inclusion rates of 11 and 33% and one with inclusion rates of up to 50%, as well as a 2-year feeding trial with inclusion rates of 11 and 33% in male and female Wistar Han RC [...]

Genetically engineered crops help support conservation biological control

By Community Manager - Mar 08, 2019

Highlights: Insecticidal Bt crops were grown on more than 100 million hectares in 2017. Risk assessment considers exposure and toxicity of natural enemies to Bt proteins. Bt proteins appear not to harm natural enemies. Reduced insecticide use in Bt crops can enhance the conservation of natural enemies. Bt technology represents a powerful tool for IPM. Abstract: Genetically engineered (GE) crops producing insecticidal proteins from Bacillus thuringiensis (Bt) (mainly Cry proteins) have become a major control tactic fo [...]
