4) Molecular formula: C15H19N5O7S
5) Molecular weight: 413.4
6) CAS no.: 94593-91-6
Physical-chemical properties:
1) Appearance: colorless crystalline powder
2) Melting point: 127.0 - 135.2oC (pure)
3) V.p.: <0.01mPa (25oC)
4) KOWlogP: 2.04 (pH 2. 1, 25oC)
5) S.g./density: 1.47 (20oC)

1) Appearance: light yellow powder
2) a.i. content (m/m): 92.0% (minimum)
3) Moisture content (m/m): 1.0% (maxnimum)
4) pH value: 3 ?5
Formulation: 10WP
Analysis: HPLC
Packaging: 25kg/plastic woven bag or cardboard drum lined with plastic bag
Applications:
1) Biochemistry: branched chain amino acid synthesis (acetolactate synthase or ALS)
inhibitor. Acts by inhibiting biosynthesis of the essential amino acids valine
and isoleucine, hence stopping cell division and plant growth
2) Action: absorbed primarily by shoots and roots, and translocated to actively growing
meristematic tissue.
3) Uses: applied post-emergence to control many weeds, including Alisma, Annaal Cyperus
Eleocharis, Marsilea, Potmnogeton and Sagittarla spp., Monochoria vaginalis
and Sphenoclea zeylanica in transplanted, directly seeded, wet-sown, water-sown,
and dry-sown rice crops, at 20 - 80g/ha. Also used in tropical plantation crops.
For full weed spectrum, may need to be combined with a grass herbicide in tank-mix
or sequential treatment.
Toxicology:
1) Oral: acute oral LD50 rats and mice >5000mg/kg
2) Skin and eyes: acute percutaneous LD50 for rats >2000mg/kg
not irritating
to skin or eyes of rabbits. Non-sensitising to skin (guinea pigs).
3) Inhalation: LC50 for rats >5mg/L air
4) NOEL: (2y) in rats 400, mice 60ppm
(1y) for dogs 2500ppm
5) Birds: acute oral LD50 for Japanese quails >2000mg/kg
6) Fish: LC50 (96h) for rainbow trout >100mg/L
7) Bees: non-toxic
LD50 (oral and contact) >100ug/bee
8) Worms: LC50 (14d) for Eisenia foetida 1000mg/kg
9) Daphnia: LC50 (48h) 2500 mg/L
