What is the Difference Between Brodifacoum and Bromadiolone?
🆚 Go to Comparative Table 🆚Brodifacoum and bromadiolone are both toxic substances that can act as pesticides, specifically as anticoagulant rodenticides. They are used to control rodent populations, such as Norway rats, ship rats, and house mice. The key differences between brodifacoum and bromadiolone are:
- Potency: Brodifacoum is more potent than bromadiolone. Brodifacoum is a single-dose anticoagulant, meaning it requires only one dose to be effective, while bromadiolone is a multi-dose anticoagulant, requiring multiple feedings to achieve the desired effect.
- Mode of Action: Both substances work by interfering with the synthesis of clotting factors, resulting in hemorrhaging and death. They antagonize the enzyme vitamin K1-epoxide reductase in the liver, causing a decrease in blood clotting time.
- Appearance: Brodifacoum and bromadiolone both appear as off-white to fawn-colored powders.
- Chemical Formula: The chemical formula of brodifacoum is C31H23BrO3, while the chemical formula of bromadiolone is C31H23BrO3.
- Resistance: So far, no practical resistance has been observed in rodents against brodifacoum, while resistance has been observed against bromadiolone.
In summary, brodifacoum is a more potent single-dose anticoagulant rodenticide compared to bromadiolone, which is a multi-dose anticoagulant rodenticide. Both substances work by interfering with the synthesis of clotting factors, but brodifacoum is more effective at a single dose and has not yet been observed to cause resistance in rodents.
Comparative Table: Brodifacoum vs Bromadiolone
Brodifacoum and bromadiolone are both anticoagulant rodenticides, which act as pesticides. The key difference between the two is that brodifacoum is more potent than bromadiolone. Here is a comparison table highlighting their differences:
Property | Brodifacoum | Bromadiolone |
---|---|---|
Chemical Formula | C31H23BrO3 | C31H23BrO3 |
Appearance | Off-white to fawn-colored powder | Off-white to fawn-colored powder |
Potency | More potent | Less potent |
Both chemicals are 4-hydroxycoumarin vitamin K antagonist anticoagulants. They work by interfering with the normal blood clotting process, leading to excessive bleeding and eventually death in the targeted pests. However, brodifacoum is known to be more toxic and has a higher single-feeding effectiveness than bromadiolone.
