Premix
Water dispersible granule, flowable. 
Premix Parters: mepiquat chloride;
Physical Properties
Molecular weight:350.3; Physical form:Orange crystals. Density:1.41 (25 °C); Melting point:122.5-124 °C; Flash point:196 °C; Vapour pressure:0.0033 mPa (25 °C); Henry constant:8.89 × 10-2 Pa m3 mol-1 ( calc.); Partition coefficient(n-octanol and water):logP = 4.1007 (25 °C, unstated pH); pKa:11.5, strong base; Solubility:In water 0.013 mg/l (25 °C). In acetone 226, acetonitrile 45, benzene 74, chloroform 93, ethanol 7, hexane 20, xylene 35.4 (all in g/l, 20 °C).; Stability:Moderately stable to light. Decomposes at 240 °C.
Toxicology
Oral:Acute oral LD50 for rats >5000 mg/ kg. Percutaneous:Acute percutaneous LD50 for rats >2000 mg/kg. Mildly irritating to eyes; non-irritating to skin (rabbits). Not a skin sensitiser. Inhalation: LC50 (4 h) >0.256 mg/m3 (maximum achievable). ADI:( JMPR) 0.1 mg/ kg b.w. [1989].
Environmental Profile
Ecotoxicology: 
Algae: EC50 (24-96 h) 3-10µg/l.Bees:LD50 (topical) >100µg/bee.Birds:Acute oral LD50 for bobwhite quail >2250 mg/kg. Dietary LC50 (8 d) for bobwhite quail and mallard ducks >10 000 mg/ kg daily.Daphnia: LC50 (48 h) >658µg/l.Fish: LC50 (96 h) for rainbow trout >829, bluegill sunfish >552µ>g/l. 

Environmental fate: 
Animals:In rats, orally administered prodiamine is almost completely eliminated within 4 d.Soil:Prodiamine is subject to photodegradation. Metabolism involves reduction of the nitro groups. Typical DT50 in sandy loam (field) 69 d. Strongly adsorbed on soil; WATER SOLUBILITY: 0.013 mg/l at 25°C HAZARDS: Fish: (96 h) LC50 >829 μg/l (rainbow trout); >552 μg/l (bluegill sunfish). Bird: Oral LD50 >2250 mg/kg (bobwhite quail). Bee: Topical LD50 >100 μg/bee
Transport Information
Signal Word:CAUTION; Hazard Class:III(Slightly hazardous)
