Sulfosulfuron Usage And Synthesis

Uses

Herbicide.

Agricultural Uses

Sulfosulfuron (MON 37500) is a post‐emergent herbicide for the control of grass (especially Bromus sp.) and broadleaf weeds in cereal crops at rates of 10–35 g a.i. ha−1. Sulfosulfuron was jointly developed by Monsanto Company and Takeda Chemical Industries and launched in 1997. As barley and oats are both sensitive to applications of sulfosulfuron, its use in these crops is not recommended. At rates of 20–30 g a.i. ha−1, the following weeds are controlled with at least 85% efficiency: Elymus repens, A. spica‐venti, Agrostis stolonifera, Avena fatua (North America), Bromus commutatus, B. japonicus, B. mollis, B. rigidus, B. secalinus, B. sterilis, B. tectorum, Poa bulbosa and Poa trivialis, Ambrosia artemisiifolia, Amsinckia lycopsoides, Atriplex patula, Brassica nigra, C. bursa‐pastoris, Claytonia per, Descurainia pinnata, D. sophia, Fumaria officinalis, G. aparine, Helianthus sp., Matricaria chamomilla, M. inodora, P. aviculare, P. persicaria, S. arvensis, Sisymbrium altissimum, S. media, T. arvense, and V. arvensis. In Europe, sulfosulfuron is commercially available under the trade name “Monitor®.”
