摘要：

Previous studies have shown that starch-based bioplastic granules can serve as an effective formulation for delivering biocontrol and bioremediation fungi. This field study evaluated the feasibility of this approach for reducing injury potential and/or carry over risk caused by the in season application of the herbicide Bicyclopyrone (BIR) on two sensitive crop species. Planting soybean in field plots simultaneously sprayed with BIR at 50, 100 and 200 g ha(-1) resulted in an average plant injury of 60, 80 and 93%, respectively. Plant injury decreased when the two sensitive crops were planted at increasing time interval from BIR treatment. Application of bioplastic granules inoculated with Beauveria bassiana, Rhizopus oryzae or Trichoderma harzianum led to a significant reduction of carry over risks. In 2012, at 7 days after treatment, plots amended with inoculated granules showed a reduction of plant injury higher than 50%. Reduced plant injury was recorded in 2013. However the effect of inoculated granules was consistent with that observed in the previous year. Findings from this field study showed that this technology is promising in reducing herbicide carry over risk. This novel triketone herbicide BIR was used here as a model for evaluating this approach, thus not excluding the possibility to be extended to other classes of residual herbicides.
