Elsbeth from Renton Wa writes

I have been using Barricade 4FL for several years on gravel, beautibark etc for several years.

I have been using Barricade 4FL for several years, but I use it only on Bark, gravel etc. I was told to use 3oz per gallon. Is that the amount I need to use or can I use less?

Answer:

You will need to use 0.5 – 1.1 oz of Barricade 4FL per 1,000 sq. ft. for ornamental type areas, the amount of water you will need depends on the amount of water it takes to irrigate that area. If you're unsure, you will need to calibrate your sprayer. Please read the product label for complete application instructions.
