bromothalonil

Bromothalonil Overview

• Bromothalonil is a low-toxicity, broad-spectrum compound with fungicidal, anti-mold, and algicidal properties138.

Chemical and Application Details

• Chemical Name: 1,2-dibromo-2,4-dicyanobutane, with the molecular formula C6H6Br2N25.
• Appearance: White or pale yellow crystalline powder1.
• Usage: Effective in controlling fungal, bacterial, and algal growth, particularly for anthracnose disease on fruits and vegetables47.
• Production: Derived from the dimerization of acrylonitrile to form 2-methyleneglutonitrile, followed by bromination1.

Environmental and Toxicological Considerations

• Stereoselectivity: (+)-Bromothalonil is more degradable and has higher bioactivity with lower toxicity compared to its enantiomer76.
• Environmental Impact: Systematic assessments of its ecotoxicological effects and environmental fate are conducted46.
• Toxicity: Acute toxicity tests indicate high toxicity to Eisenia foetida, with potential lysosomal membrane damage10.

Regulatory and Analytical Methods

• Regulatory Status: Registered in China for agricultural use, with specific records available5.
• Residue Analysis: QuEChERS method combined with analytical techniques for residue detection in apples and soil9.
