Why should herbicides be stored separately from other pesticides?

Storing herbicides separately from other pesticides is important primarily because they can vaporize and contaminate adjacent pesticides. Herbicides often have volatile compounds that can release vapors, which might drift to neighboring containers, potentially causing unwanted reactions or contamination of other substances. This can compromise the effectiveness of those pesticides or create new, unintended problems, such as hazardous chemical reactions or altered toxicity.

The other considerations, such as requiring more space, being more expensive, or having lesser effectiveness, do not address the critical safety and efficacy concerns that arise from potential contamination. Ensuring that herbicides are stored in isolation helps maintain the integrity and safety of both the herbicides and the other pesticide products, promoting safer handling and application practices.
