Syngenta to debut mesotrione for fruit in US
Syngenta plans to introduce the herbicide, Broadworks (mesotrione), for use on citrus, stone fruit and nut trees in the US. It would be the first hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor for use on those crops and would aid resistance management, the company points out. It would be particularly useful for the control of marestail (Conyza canadensis) and fleabane (C bonariensis) that have developed resistance to glyphosate or other herbicides, Syngenta notes. The herbicide provides residual control of broadleaf weeds and some grasses. The EPA has scheduled a registration decision for use on pome, stone and citrus fruit, and nut trees by mid-2015. Mesotrione is approved for use in many agricultural and non-agricultural settings but is predominantly used on maize. The EPA began a registration review of mesotrione this year.
