Recently, a research team led by WU Zhengyan from Hefei Institutes of Physical Science (HIPS) of the Chinese Academy of Sciences developed a new kind of light-responsive herbicide with high efficiency but low cost, which is expected to be widely applied.
The researchers used a nanocomposite to develop a light-responsively controlled-release herbicide particle (LCHP), which means the release of the herbicide depends on its radiation of UV-Vis. In recent years, controlled-release pesticides (CRP) has become one of the hot spots in agriculture and environment fields.
Several kinds of CRPs have been fabricated using pH and temperature responsive materials. The release could be efficiently adjusted by pH and temperature to match the demand of crops, however, resulting in a rather high UE.
