jaideeguy Posted April 23, 2009 Share Posted April 23, 2009 Can several flushes of warm soapy water safely remove round-up from a backpack sprayer so it can be used to spray insecticides safely without any residue to harm [wanted] plants?? Don't want to have to buy another sprayer, but will if it will cause damage. Link to comment Share on other sites More sharing options...
slapout Posted April 23, 2009 Share Posted April 23, 2009 That is how I always cleaned the tank, several wash's with soapy water and then rinse with clean water. Be sure and pressure up tank and wash out the wand (spray head) I found taking off the nozzle would speed the procedure up. Link to comment Share on other sites More sharing options...
jaideeguy Posted April 23, 2009 Author Share Posted April 23, 2009 And you have used the same sprayer for herbicides and insecticides?? I did a google and got conflicting info. I'll be spraying some valuable asparagus plants and really don't want to do any damage to them. Link to comment Share on other sites More sharing options...

You should wash the pesticide immediately after you finished the job, do not allow it to dry inside the tank. If in doubt soak it over night with soapy water, you’ll be fine!
