Is it advisable to store unused spray mixtures in the sprayer for a day or two?

Storing unused spray mixtures in the sprayer for a prolonged period, even just a day or two, is not advisable for several important reasons. First, chemical stability can be affected when pesticide formulations are left in the tank. Certain components of the mixture can degrade or react with one another, leading to reduced effectiveness or even the formation of harmful byproducts.

Additionally, leaving the mixture in the sprayer can lead to clogging of hoses and nozzles due to precipitation or sedimentation of the mixture’s components. This could ultimately require more time and effort to clean the sprayer before it can be used again.

Furthermore, there are safety concerns associated with leaving pesticides in equipment. If something were to leak or spill, it could pose risks to people, pets, or the environment, especially during the duration the mixture remains in the sprayer.

To maintain effectiveness, ensure equipment cleanliness, and prioritize safety, it is best practice to only prepare pesticide mixtures that can be applied immediately and to clean the sprayer promptly afterwards.
