Moderately irritating to rabbit eyes and slightly irritating to rabbit skin. Negative in the Ames test and the mouse micronucleus test. LC50 in quail and mallard > 5620 mg/L, 1.2 mg/L in bluegill, 2.9 mg/L in carp, and 1.3 mg/L in rainbow trout (all within 96 hours). LC50 in Daphnia 360 is 2.9 mg/L (48 hours).

Uses: Thiazoleamide succinate dehydrogenase inhibitor. It is used for rice, cereals, and lawns. It is effective against pathogenic fungi such as Rhizoctonia, Puccinia, Tine, Corticotropha, and Ustilago. It is particularly effective against diseases caused by Basidiomycetes, such as damping-off. For foliage treatment of rice, cereals, and lawns, the dosage is 125-250 g active ingredient/hm². For seed dressing of cereals and non-cereal crops, the dosage is 7-30 g active ingredient/kg seed. It has excellent control effects against sheath blight in rice at a dosage of 130-140 g active ingredient/hm², and against rust in cereals at a dosage of 125-250 g active ingredient/hm².
