| Common name: |
trifloxysulfuron |
| Chemical name: |
N-[[(4,6-dimethoxy-2-pyrimidinyl)amino]carbonyl]-3-(2,2,2-trifluoroethoxy) |
| -2-pyridinesulfonamide |
| CAS No: |
145099-21-4 |
| Molecular Formula: |
C14H14F3N5O6S |
| Pesticide category: |
Herbicide |
| Mode of Action: |
Readily absorbed by shoots and roots and is translocated via xylem and phloem
to shoots, roots and apical meristems. Susceptible weeds show chlorotic symptoms
within days and die within 1-3 weeks. |
| Characteristics and Uses: |
The sodium salt is under development for post-emergence grass, sedge, and broad-leaved weed control, at 5-7.5 g/ha, in cotton, and, at 1500 g/ha, in admixture with ametryn, in |
| sugar cane. Weed control in plantations and in turf are also being |
| examined. Weeds controlled include Cyperus spp., Euphorbia spp., |
| Ipomoea spp., Cassia spp., Xanthium spp., Brachiaria spp., and |
| Rottboellia exaltata. |
| Toxicity: |
Oral: Acute oral LD50 for rats >5000 mg/kg. |
| Skin and eye: Acute percutaneous LD50 for rats >2000 mg/kg. |
| Non-irritating to skin and eyes (rabbits). |
| Not a skin sensitiser (guinea pigs). |
| Inhalation: LC50 for rats (4 h) >5.03 mg/l. |
