What is the Difference Between Butachlor and Pretilachlor?
🆚 Go to Comparative Table 🆚Butachlor and pretilachlor are both herbicides used to control weeds, but they belong to different classes and have distinct characteristics:
- Class: Butachlor is an acetanilide herbicide, while pretilachlor is an anilide herbicide.
- Chemical Formula: The chemical formula of butachlor is C17H26ClNO2, and for pretilachlor, it is C17H26ClNO2.
- Formulation: Butachlor is marketed as a 50% emulsifiable concentrate formulation, while pretilachlor is marketed as a 50% emulsifiable concentrate formulation.
- Selectivity: Butachlor is a selective systemic herbicide, while pretilachlor is a broad-spectrum systemic herbicide.
Both herbicides work in a similar way, as they interfere with the growth of weeds. However, due to their differences in class and selectivity, they may have varying effects on different weed species and may be used in different contexts or applications.
Comparative Table: Butachlor vs Pretilachlor
Butachlor and Pretilachlor are both herbicides that belong to the acetanilide class, but they have some differences in their properties and usage. Here is a table comparing the two:
Property/Usage | Butachlor | Pretilachlor |
---|---|---|
Chemical Class | Acetanilide | Anilide |
Formula | C17H26ClNO2 | C17H26ClNO2 |
Molar Mass | 311.85 g/mol | 311.85 g/mol |
Density | 1.0695 g/cm³ | - |
Solubility | Poor | 50 mg/l |
Formulation | Emulsifiable concentrate | 50% emulsifiable concentrate |
