 | Hazard Information | Back Directory |  | [Description] 
 log Kow: 1.4. Solubility: In water at 25 ?C,
1.6 g/L. In acetone 10.4, methanol 25, xylene 2.1 (all in
g/l, 25 ?C). Stability: Stable at 52 ?C. Relatively stable
to ultraviolet light.
 |  | [Chemical Properties] 
 The original drug is an off-white solid that is not easily decomposed by water and light and is also stable to heat (up to 187°C).
 |  | [Uses] 
 Tricyclazole is an common active ingredient in several commercial fungicide products used to control rice blast fungus, in transplanted and direct-seeded rice.
 |  | [Definition] 
 ChEBI: A triazolobenzothiazole that is [1,2,4]triazolo[3,4-b][1,3]benzothiazole which is substituted at position 5 by a methyl group. A fungicide used for the control of rice blast, it is not approved for use within the European Union.
 |  | [Metabolism] 
 Animals: Rapid and extensive metabolism.
 Plants: The principal metabolite is the hydroxymethyl
analog.
 Soil/Environment: Kd 4 (loamy sand, pH 6.5, 1.5%
o.m.), 45 (loam, pH 5.7, 3.1% o.m.), 21 (clay loam, pH 7.4,
1.9% o.m.), 22 (silty clay loam, pH 5.7, 4.1% o.m.).
 |  | [Toxicity evaluation]
