Leaving Roundup in your sprayer is generally not recommended. While it might seem convenient to store it that way for your next use, doing so can lead to several issues, including damage to the sprayer and potential degradation of the herbicide.
Why You Shouldn’t Leave Roundup in Your Sprayer
1. Chemical Degradation
Roundup, which contains glyphosate, can break down over time, especially when exposed to heat or sunlight. If you leave it in the sprayer, the effectiveness of the herbicide may diminish. This means you might not get the results you expect when you finally use it again.
2. Sprayer Damage
Leaving Roundup in your sprayer can lead to clogging or corrosion of the internal components. The chemicals can crystallize or react with materials in the sprayer, which could result in costly repairs or even the need for a new sprayer altogether.
3. Safety Concerns
If you leave Roundup in your sprayer, there’s a risk of accidental exposure when you go to use it again. Residue can remain and potentially harm you or others if proper safety measures aren’t followed.
4. Environmental Impact
Improper storage of herbicides can lead to spills or leaks, which can be harmful to the environment. By not leaving Roundup in your sprayer, you reduce the risk of unintended contamination.
Best Practices for Storing Roundup
- Empty the Sprayer: After using Roundup, make sure to empty any remaining solution.
- Clean Thoroughly: Rinse your sprayer with water and clean it according to manufacturer instructions.
- Store Properly: Keep your sprayer in a cool, dry place away from direct sunlight.
