Topramezone is the first post seedling herbicide developed by BASF for corn fields, which is a 4-hydroxyphenylpyruvate oxidase (4-HPPD) inhibitor. Since its launch in 2011, the product name “Baowei” has been listed in China, breaking the safety defects of conventional corn field herbicides and attracting industry attention.
The most prominent advantage of topramezone is its safety for corn and subsequent crops, and it is widely used in almost all corn varieties such as regular corn, glutinous corn, sweet corn, field corn, and popcorn. At the same time, it has a wide herbicide spectrum, high activity, and strong miscibility, and has good control effects on weeds that are resistant to glyphosate, triazine, acetyllactate synthase (ALS) inhibitors, and acetyl CoA carboxylase (ACCase) inhibitors.
According to reports, in recent years, as resistant weeds in corn fields have become increasingly difficult to control, the profit and control effectiveness of traditional tobacco and nitrate herbicides have decreased, and domestic pesticide companies have paid increasing attention to topramezone. With the expiration of BASF’s patent in China (patent number ZL98802797.6 for topramezone expired on January 8, 2018), the localization process of the original drug is also steadily advancing, and its market will gradually open up.
In 2014, global sales of topramezone were 85 million US dollars, and in 2017, global sales rose to a historical high of 124 million US dollars, ranking fourth among HPPD inhibitor herbicides (the top three being nitrosulfuron, isoxacloprid, and cyclosulfuron). In addition, companies such as Bayer and Syngenta have reached an agreement to jointly develop HPPD tolerant soybeans, which has also contributed to the growth of sales of topramezone. From the perspective of global sales volume, the main sales markets of topramezone are in countries such as the United States, Germany, China, India, Indonesia, and Mexico.
