1,Product Introduction:

Triadimefon is a fungicide used in agriculture to control various fungal diseases. As a seed treatment, it is used on barley, corn, cotton, oats, rye, sorghum, and wheat.


 It is available in wettable powder, emulsifiable concentrate, granular, and paste forms.

3,Ecological Effects:

Effects on birds: Triadimefon ranges from slightly toxic to practically nontoxic to birds.

For instance, the compound has an LD50 value of greater than 4000 mg/kg in mallard ducks .

Japanese quail are less tolerant of the compound (LD50 of 2000 mg/kg) and canaries are even less tolerant (LD50 >1000 mg/kg) . Even the most tolerant species exhibited some compound-related acute toxicity such as diarrhea and regurgitation within 5 minutes of administration of the highest doses. At the lowest dose tested (500 mg/kg) no signs of diarrhea were noted .


Effects on aquatic organisms: The compound is slightly toxic to fish, indicating that they are more susceptible to the presence of the compound than are birds. Bluegill sunfish are the most susceptible, followed closely by goldfish, with 96-hour LC50 values of 11 mg/L and 10 to 50 mg/L, respectively . The compound is only slightly toxic to rainbow trout, with a reported LC50 of 14 mg/L .

Effects on other organisms: The compound is nontoxic to honeybees .


Triadimefon is used to control various fungal diseases in fruit (pineapple) and non-food use sites such as: pine seedlings, Christmas trees, residential (sod farm) and commercial turf, ornamentals, and landscapes.

Triadimenol is used as a seed treatment on: barley, corn, cotton, oats, rye, sorghum, and wheat. There is also an import tolerance for bananas.

Total triadimefon use averaged 135,000 lbs ai/year with an upper-end estimate of 266,000 lbs ai/year.

Approximately 24,000 lbs ai of triadimenol are applied annually.
