I have a 25 gallon sprayer, I marked off 1,000 sf and walked a normal pace spraying water and did it in 1 minute. I then sprayed for 1 minute in a calibration measuring container. It came up with 1/2 gallon. My question... If I am putting down Pendelum and it calls for 1.3 - 1.8 oz per 1,000 sf., If I was to use 1.5oz per 1,000 sf. How much Pendelum should I use?
