How many ounces of Surflan do I need to use per gal of water?

I have evergreen trees planted in rows. How many ounces of Surflan do I need per gallon to control weeds for 4 months? Cultivation of soil around trees is not possible. Will this product still work?


Surflan Pro is a pre-emergent weed control product. Surflan Pro does not control emerged weeds, established weeds, weeds growing from stolens, rhizomes, or root pieces. The area to be treated with this product needs to be weed free at the time of the application. You will need to use 3 fl oz of product per 1-2 gallons of water for 1,000 sq ft. The water in this case is just a carrier and you need to use enough water to make sure you get even coverage and to make sure you are getting the correct amount of product over the 1,000 sq ft area. There are directions on page 7 of the Surflan Pro product label that explains how to properly calibrate your sprayer.
