Bifenizumab interferes with the succinate dehydrogenase on complex II in the mitochondrial respiratory electron transport chain of pathogenic bacteria, inhibits mitochondrial function, prevents it from producing energy, inhibits the growth of pathogenic bacteria, and ultimately leads to its death.

Bifefenpyrid is a systemic fungicide with a broad bactericidal spectrum and is specially used for foliar spraying. It can effectively prevent and control important diseases caused by ascomycetes, basidiomycetes and deuteromycetes on cereal crops. Tests have proven that bifenzofen has excellent control effects on many diseases on wheat crops, such as wheat leaf blight (Septoria tritici), leaf rust (Puccinia triticina), stripe rust (Puccinia striiformis), eye spot ( Oculimacula spp.) and yellow spot (Pyrenophora tritici-repentis), etc., as well as barley net spot (Pyrenophora teres), Ramularia collo-cygni, moire (Rhynchosporium secalis) and leaf rust (Puccinia hordei), etc., and can prevent and control leaf spot (Septoria tritici) caused by Septoria tritici pathogens that are resistant to methoxyacrylate fungicides.

It is reported that bifenzofen has a good therapeutic and protective effect on barley net spot and apple powdery mildew; its compound product with prothioconazole is effective against Septoria spp. Diseases have very good activity.

European Union registration takes the first step

In 2008, a registration application for bifenzofen was submitted to the UK. In September 2010, Aviator Xpro, a compound product of bifenzofen and prothioconazole, was approved for registration in the UK for use on wheat and barley. In the same year, the compound product was registered in Germany. In 2011, the Xpro series of products based on bifenac were first launched in the UK, Germany, France, Ireland and Chile, and then in many European markets.

On October 1, 2013, bifenzofen was included in the list of registered active ingredients in the EU Pesticide Registration Regulation (1107/2009), which is valid until September 30, 2023. The UK is the drafting country of the document. Currently, bifenzofen is available in 18 EU member states (Austria, Belgium, Bulgaria, Czech Republic, Germany, Estonia, France, Hungary, Ireland, Italy, Lithuania, Luxembourg, Latvia, the Netherlands, Poland, Romania, Slovakia, and the United Kingdom). ) has been registered, and 4 member states (Spain, Finland, Sweden and Slovenia) are currently registering.

Registration requirements, EU member states must pay special attention to: residues of diphenoxyfen and its metabolites in rotation crops; when used in areas with fragile soil and/or climatic conditions, attention should be paid to the impact on groundwater Conservation; be aware of risks to aquatic life; be aware of risks to organisms that inhabit soil and sediments.

In the European market, 125 g/L diphenoxylin EC foliar spray is used for wheat, rye, triticale, barley and oats to prevent and control stem and leaf diseases.

Companies such as FMC and Sumitomo Chemical are also involved in the development of bifenzofen in other markets.

FMC has obtained an exclusive license to develop and distribute bifenzofen in the United States and Canada. FMC will develop a range of products based on bifenzofen, thereby further growing the market for this active ingredient. The company is in the process of registering multiple compound products of bifenzofen.

Recently, FMC, the U.S. Environmental Protection Agency (EPA) and the Canadian Pest Management Regulatory Authority (PMRA) have jointly promoted the registration of bifenzofen. The registered crops include corn, soybeans, cereals, canola, peanuts and potatoes. Submitted registration information shows that bifenzofen can effectively control corn leaf blight and gray leaf spot, soybean gray spot, brown spot and white rot; leaf spot caused by Septoria on cereals , stripe rust and stem rust; potato early blight and white rot; rapeseed white rot; peanut stem rot, leaf spot, leaf rust and stem rot caused by Rhizoctonia.

FMC is the world’s leading provider of plant protection solutions. Through strategic alliances, cooperation and acquisitions, the company’s R&D pipeline already has 16 new synthetic and biological active ingredients, including bifenzofen. The product will be on the market within the next 7 years.

In addition, the Australian Pesticides and Veterinary Medicines Authority (APVMA) has also approved the registration of Aviator Xpro (75 g/L diphenoxylin + 150 g/L prothioconazole), a foliar fungicide from Atomo Chemical, for control. Barley, oats, triticale, �Foliar diseases on crops such as wheat and rapeseed.

As of October 2016, bifenzofen has not yet been registered in my country.

The main compound products of bifenfenpyr are: Aviator Xpro, Aviator 235 Xpro, Siltra Xpro (+ prothioconazole), SkywayXpro (+ prothioconazole + tebuconazole), Input Mycloconazole + spirolostrobin), VarianoXpro (+ prothioconazole + fluoxastrobin), and Zantara (+ tebuconazole), etc. Compatible products include not only prothioconazole, but also tebuconazole, fluoxastrobin, and spironil; there are both two-component and three-component compounds.

Market development is like a duck in water

Bifenizumab has been like a duck in water since it was launched in 2011, and its market has developed rapidly. Especially with the successful launch of the Xpro series of compound products of bifenpyrid and prothioconazole, the market has grown significantly.
