Glyphosate has the largest consumption among the sterilant herbicides; besides, it is widely used with low price. However, after using for years with large quantity, glyphosate's effect on perennial malignant weeds weakens. Glufosinate-ammonium, with excellent effect on parts of malignant weeds resistant to glyphosate, covers the shortage of glyphosate. Recently, some domestic enterprises put forward the application for registrations on formulations mixed by glyphosate and glufosinate-ammonium. For this, the ICAMA collects suggestions and opinions concerning the rational mix proportion for these formulations. In fact, the formulations mixed by glyphosate and glufosinate-ammonium can help solve the problem of glyphosate resistance. Meantime, it can increase the consumption of glufosinate-ammonium. If the mixed formulations are developed and registered successfully, glyphosate and glufosinate-ammonium will have promising development prospect. Nevertheless, at present, related products are still undergoing primary stage of registration application, and the MOA should arrange various experiments after determining the rational mix proportion. Therefore, it will take at least two years for the registration approval. Currently, due to the insufficient production capacity and exorbitant price of glufosinate-ammonium, the market demand is not fully released. What's more, there are still few enterprises can achieve mass-production on glufosinate-ammonium, due to production technique, safety and high requirements of environmental protection. It is believed that if the mixed formulations of glyphosate and glufosinate-ammonium are launched on the market, the consumption volume will be stimulated to some extent.
