When is the best time to add pesticide to the spray tank?

Adding pesticide to the spray tank immediately before application is the best practice because it ensures that the pesticide is as effective as possible when it is applied to the target area. Pesticides can degrade over time due to factors like light, temperature, and chemical instability; therefore, mixing and applying them right away helps maintain their potency and efficacy.

By mixing them right before application, you also minimize the chance of sedimentation or separation within the tank, as some products may settle or stratify if left standing for a long period. This practice allows for a uniform mixture, which is crucial for consistent coverage and effective pest control.

In contrast, adding pesticides several hours or even days in advance can lead to reduced effectiveness due to these stability and mixing issues, which is why those options are less ideal for optimal pest control outcomes.
