Yield Analysis and Adaptation for Bacillus Thuringiensis (BT) and Non-Bacillus Thuringiensis (BT) Cotton Varieties in the Kingdom of Eswatini

Bt a short history of Bacillus thuringiensis

The impact of secondary pests on Bacillus thuringiensis (Bt) crops.

The intensification of agriculture and the development of synthetic insecticides enabled worldwide grain production to more than double in the last third of the 20th century. However, the heavy dependence and, in some cases, overuse of insecticides has been responsible for negative environmental and ecological impacts across the globe, such as a reduction in biodiversity, insect resistance to i...

FIFRA SCIENTIFIC ADVISORY PANEL Subpanel on Bacillus thuringiensis (Bt) Plant-Pesticides and Resistance Management The Subpanel on Bacillus thuringiensis (Bt) Plant-Pesticides and Resistance Management of the FIFRA

The above mentioned meeting of the FIFRA Scientific Advisory Panel (SAP) Subpanel on Bacillus thuringiensis (Bt) Plant-Pesticides and Resistance Management was an open meeting held in Arlington, Virginia to review a set of scientific issues and specific questions posed by the Environmental Protection Agency (EPA) based on its "White Paper". Please find attached the Subpanel's final report of fi...

Varying Levels of Cry1Ac in Transgenic Bacillus thuringiensis Berliner (Bt) Cotton Leaf Bioassays1

Research was conducted to determine levels of Cry1Ac in transgenic Bacillus thuringiensis Berliner (Bt) cotton leaves from four different commonly used bioassays. Significant differences in the amount of Cry1Ac were found among the different bioassay types. For bioassay arenas that prevented desiccation of leaf material, Cry1Ac levels remained stable for 10 d after tissue was excised from the p...

Field evaluation of arbuscular mycorrhizal fungal colonization in Bacillus thuringiensis toxin-expressing (Bt) and non-Bt maize.

The cultivation of genetically engineered Bacillus thuringiensis toxin-expressing (Bt) maize continues to increase worldwide, yet the effects of Bt crops on arbuscular mycorrhizal fungi (AMF) in soil are poorly understood. In this field experiment, we investigated the impact of seven different genotypes of Bt maize and five corresponding non-Bt parental cultivars on AMF and evaluated plant grow...
