What does the term "chemically incompatible" refer to?

The term "chemically incompatible" is best understood as relating to tank mixes where the interaction between one or more products leads to a reduction or unpredictable increase in their effectiveness. When two or more chemicals are mixed and their interaction negatively affects the performance of the products, this situation is described as chemical incompatibility. This can manifest as sediment formation, changes in pH, or other physical changes that can degrade the effectiveness of the active ingredients.

When considering the other options, some may imply that interactions are positive or neutral, but that doesn't align with the concept of chemical incompatibility. For example, tank mixes that enhance product activity or have no interaction would indicate compatibility rather than incompatibility. Furthermore, stating that mixes are only compatible with certain adjuvants would suggest a scenario where some products interact beneficially, not detrimentally, which contradicts the definition of incompatibility. Thus, the accurate depiction of chemically incompatible situations falls squarely within the context of reduced or altered activity due to negative interactions between mixed chemicals.
