Global Guide of Coming Off-patent Agrochemical Active Ingredients

 Penoxsulam, developed and produced by Dow AgroSciences LLC (Dow AgroSciences), is a trizolopyrimidine herbicide applied in paddy fields with the widest herbicidal spectrum. It has great effect not only on aquatic weeds control but also on barnyard grass which has resistance to herbicides like quinclorac, propanil and sulfonylurea.

Penoxsulam was registered in U.S. Environmental Protection Agency in 2004; later in 2005, it got promoted and applied in paddy fields in the southern US in 2005.

In 2006, penoxsulam was used in Spain, Brazil, Columbia, South Korea and Thailand.  

In 2007, it was registered in Japan and China. In 2009, penoxsulam finally entered the China's market.

"After years of development, penoxsulam enjoys a very potential future in the market," stated Chen Zaoqun, chief editor of Herbicide China News, CCM.

In fact, when penoxsulam first came into the market, the global sales volumes was less than USD10 million, but in 2009, the sales volumes reached USD110 million. In 2013, the sales volumes climbed to about USD225 million.

Penoxsulam also has a great performance in weed control in non-agriculture market such as in lawns and in orchards. In 2013, the sale volume of penoxsulam applied in non-agriculture market reached about USD140 million, which surpassed that of those applied in paddy fields, USD110 million.

Currently, most of the penoxsulam is applied on paddy fields and the paddy cultivation countries are mainly in Asia-Pacific and East Africa. Those markets belong to middle- and low-end market; thus, it is not difficult for enterprises to register penoxsulam products.

"Penoxsulam’ great effect in weeds control makes it be needed in the market and it would be consumed most in Asia-Pacific in the next five years," Chen commented.


Besides, according to CCM's research, there is no substitute product for penoxsulam; thus, penoxsulam would be the key product in weeds control in paddy fields.
