Toxapyzone is a new herbicide compound derived from topramezone, developed by Shandong Dehao Chemical. It delivers excellent preventive and curative control of a wide range of troublesome weeds at low application rates. Toxapyzone offers strong resistance to rain erosion and is particularly effective against red root barnacles, tiger grass, sedge family weeds such as Cyperus rotundus, and broadleaf weeds including quinoa, Amaranthus chinensis, field bindweed, Amaranthus retroflexus, commelina, thistle, and Channa chus.
Notably, Toxapyzone demonstrates high crop safety in corn—including conventional varieties like Zhengdan 958, as well as glutinous and sweet corn—making it a versatile and reliable solution for modern weed management.
