When two pesticides can be safely mixed together, how are they described?

When two pesticides can be safely mixed together, they are described as compatible. This means that the combination of the two substances does not lead to any adverse reactions or reduce their effectiveness. Compatibility ensures that both pesticides can work together to enhance pest control without any negative side effects on the environment, plant health, or safety.

Incompatible mixtures can result in unwanted reactions, such as settling, phase separation, or degradation of the active ingredients, which can hinder their effectiveness. Synergistic refers to a situation where one pesticide enhances the activity of another when mixed, which is not necessarily the case for all compatible mixtures. Sequential mixes involve applying one pesticide after the other at different times, rather than mixing them together.
