Mixing two pesticides together without explicit instructions on the label can lead to unintended consequences. This is because pesticide formulations can contain different active ingredients, solvents, and emulsifiers, which may react negatively when combined. The label is the legal document that outlines how to use the pesticide safely and effectively, including information about mixing. If the label does not indicate that the products can be mixed, it is a strong indication that safety and efficacy concerns exist, as untested combinations could reduce the effectiveness of the pesticides or create harmful byproducts.

Using pesticides in a way that is not supported by the label goes against the principles of Integrated Pest Management (IPM) and can also violate pesticide regulations. It's essential to follow the instructions on pesticide labels carefully to ensure safe and successful application.
