Pesticides can be divided into patented and generic products. In the global pesticide market, generic products account for 70% of the total market share. Between 2008 and 2013, 99 pesticide patents phased off, including 47 kinds of herbicides, 23 insecticides, and 29 fungicides. How to effectively make full use of the phased-off patents gives the Chinese pesticide enterprises an opportunity to seize the market share. So what is the current situation of pesticide products which have just phased off in China? According to statistics, as of now, there were a number of patented TC products which phased off between 2008 and 2013 including 12 herbicides, 13 insecticides and six fungicides that have already registered in China. Among the phased-off patents, azoxystrobin, acetamiprid and thiamethoxam TC products had the most registrants, respectively 46, 41 and 23. Detailed information is as follows:

Herbicides: Product Name (No. of Registrants)

Florasulam (5), Ethoxysulfuron (2), Amidosulfuronl (2), Oxaziclomefone (2), Triflusulfuron-methyl (1), Pyraflufen-ethyl (1), Butafenacil (1), Cyclosulfamuron (1), Pyriftalid (1), Trifloxysulfuron (1), Flucarbazone (1), Monosulfuron (1).

Insecticides: Product Name (No. of Registrants)

Acetamiprid (41), Thiamethoxam (23), Fipronil (18), Emamectin Benzoate (15), Pymetrozine (11), Indoxacarb (6), Clothianidin (5), Methoxyfenozide (3), Chlorfenapyr (2), Bifenazate (2), Fenazaquin (1), Etoxazole (1), Flonicamid (1).

Fungicides: Product Name (No. of Registrants)

Azoxystrobin (46), Cyazofamid (2), Zoxamide (2), Picoxystrobin (1), Trifloxystrobin (1), Ningnanmycin (1).

Faced with the current situation, China pesticide industry should reasonably develop products the patents of which have phased off to avoid overinvestment. This will help adjust and optimize the product structure of Chinas pesticide industry, which then is conducive to a healthy and orderly development of China pesticide industry.
