Signs of pesticide incompatibility often include the formation of flakes or precipitate in the tank. This indicates that the pesticides are not mixing well, which could occur due to chemical reactions between the substances. When pesticides are incompatible, they may not achieve the intended efficacy, and their mixing could result in reduced effectiveness or even harmful reactions. Flakes can suggest that the active ingredients are separating or that precipitated matter is being formed, which compromises the quality of the application.

In contrast, even distribution of the mixture, consistent coloration throughout, and clear transparency of the solution all suggest that the components of the mixture are properly combined and homogenous, indicating compatibility rather than incompatibility.
