Chlorothalonil exposure impacts larval development and adult reproductive performance in Drosophila melanogaster. Royal Society Open Science, 2025; 12 (6) DOI: 10.1098/rsos.250136 ...

The researchers behind the study suggest rethinking how often chlorothalonil is applied. By spacing out treatments, farmers could give insect populations time to recover between sprays.

But Chlorothalonil is not an HHP. When ingested, as in eating and drinking, it has been found through extensive testing to be non-toxic. Still, it can cause eye irritation if it gets into people ...
