SOIL PREPARATION
Surflan AS controls weeds growing from seed. Surflan AS will not control emerged weeds. Surflan AS does not control established weeds, weeds growing from stolens, rhizomes, or root pieces. Therefore, areas to be treated should be free of emerged weeds. Weed residues, prunings, and trash should be thoroughly mixed into the soil or removed prior to treatment. In field applications, the soil should be in good tilth and free of clods at the time of application.
Ground Application:
Apply Surflan AS as a directed spray to the soil surface or over the top of plants. Use only a properly calibrated, low-pressure, herbicide sprayer that will apply the spray uniformly. Use screens no finer than 50 mesh in nozzles and in-line strainers. Apply the appropriate rate of Surflan AS. In all cases, use sufficient water volume to obtain uniform coverage and deliver the desired rate of Surflan AS to the treated area. The volume of water used is not critical, as long as the desired rate of Surflan AS is delivered uniformly across the area treated. When calibrating, determine the volume of water delivered by the sprayer to a given area (1,000 sq. ft., 1 acre, etc.). Then mix the desired rate of Surflan AS in the amount of water required to cover the entire area to be treated. As the amount of water used (spray volume) decreases, the importance of accurate calibration and uniform application increases. Maintain continuous agitation from mixing through application. Avoid spray pattern skips and overlaps that may result in incomplete coverage or over-application.
My work horse pre emergent

This is my main pre emergent and this brand is the most economical that I've found. I use it mixed with Roundup for pre and post emergence. This year I'm also trying it on Fescue lawns for Crabgrass prevention. I'm having a little trouble with small flakes clogging my sprayer and it's a bit of a pain to measure. It's a thick glue-like orange liquid which sticks to the measuring cup and takes some scrubbing to get out. Otherwise an effective and economical product.

Great price and fast shipment, you cannot bet that combo! I will be back for other herbicide purchases. I like doing business here because of the quality products. This is an excellent pre-emerge chemical from an A+ company. Order response was quick and detailed and shipping date was quickly determined and relayed to me.

I live in central Texas and have a terrible problem with stickers in the yard. Don't know the exact name of the stickers; we call them goatheads among other things.
Surflan AS would be a great option. It is safe to be used on most grass types including some of the most sensitive ones like St Augustine. It will control Sandburs in your yard, as well as a multitude of other broadleaf weeds. It is highly recommended that you refer to the product label prior to purchase to make sure your lawn type is listed under grass species that are tolerant to the product.

In the Label I do not see a recommendation for Tank Sprayer mixing. For non-crop land application, it recommends 4.5 oz/1000sq ft. Do you have any idea about the conversion for a 1 gallon tank sprayer?

I have about 75 acres I am treating. There is Bermuda and St Augustine but in most places it is not established very well. I work right outside the Dallas Area. The stickers are the main problem.
