Tattnall County Ag Agent Chris Tyson put this information on cleaning out valor on his Tattnall County Extension Blog.
“I know many folks are through using Valor for the year, but some folks are still using it for soybeans. I got this tank cleanout guide from Hunt Sanders, FMD Specialist for Valent, that I wanted to share with everyone. It tells how to properly clean Valor herbicide from your spray tank using Valent Tank Cleaner. It is very important to properly clean Valor out of your sprayer to prevent injury to other crops.”
