Fig. 35.24. Halogen-containing pyrimidinylsulfonyl herbicides halosulfuron-methyl (101) and imazosulfuron (102).

Both systemic herbicides halosulfuron-methyl (101 maize, 18-35 g-a.i. ha ) [192] and imazosulfuron (102 paddy rice, 75-95 g-a.i. ha ) [193] demonstrate the structural variability of ring A, e.g., by incorporation of further halogenated heterocyclic systems such as 3-Cl,4-COOMe-l-CH3-lH-pyrazol-5-yl (101) and 2-chloroimidazo[l,2-a]pyridine-3-yl (102) (Fig. 35.24).
