Current PRTF Projects Improvements in the foliage residue toxicity test Comparison of knowledge contributed to the risk assessment by two different larval tests Evaluation of the effects of different solubilizing, wetting, and dispersing agents used in lab tests Re-evaluation of the Brigg’s plant uptake model Evaluation and improvement of models used to predict over-wintering sucess of honey bee colonies Compilation and statistical analysis of pollen and nectar pesticide residue concentrations Completed PRTF Projects Evaluation of the relative toxicity of active ingredients versus formulation products Improving the honey bee larval toxicity test
