Abstract:

Glyphosate is one of the most widely used broad-spectrum herbicides in the world. However, it is difficult to distinguish weeds and crops effectively. The research and development of glyphosate-resistant crops is one of the important ways to solve this problem. Based on the PatSnap global patent database, this paper statistically analyzed the global glyphosate resistance gene patents in the United States, China and the European Union from 1983 to 2020, and summarized the general trend of global glyphosate resistance gene patent research development, main R&D institutions and technology research hotspots. The strategies and competitiveness of glyphosate resistance gene research and development in major domestic and foreign R&D institutions were compared, and the prospect of commercialization of glyphosate resistance gene development in the future was put forward.

Key words: herbicides, glyphosate-resistant, patent analysis
