A field experiment was conducted to reveal residue and degradation of triadimenol in wheat and soil.The result showed that triadimenol degraded rapidly in the wheat seedling,but lowly in the soil relatively.The half-life of triadimenol in the former was 3.82～6.02 d and in the latter was 17.17～24.92 d.Results of the two-year experiment showed when the wheat was sprayed 2 to 3 times with triadimenol 15% WP in the dosage of 900 g·hm-2 and 1800 g·hm-2,and the last application was done 21 days before harvesting,the residue of triadimenol in the grain of harvested wheat was lower than 0.2 mg·kg-1 and in the straw was lower than 5.0 mg·kg-1.The tested results demonstrated that it is safe to apply triadimenol to wheat with the recommended rate.
