Q

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

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.

Q

What is the difference between Surflan AS and Surflan Pro?

A

There is no difference between the two. Surflan AS and Surflan Pro are the same product. The manufacturer, for whatever reason, call them different things to differentiate between the product sizes, but they are the same product.

Q

What is a good pre-emergent to use in Tucson, AZ on a rock area?
Please advise as to how to apply. Can I apply with a hose end sprayer? Will it harm cactus, mesquite trees and other desert landscaping?

A

Surflan is often used for this type of weed control with great results depending on the type of weeds you are trying to prevent. You will need about 3 fl oz of Surflan per 1,000 sq ft area.

Surflan is often used for this type of weed control with great results depending on the type of weeds you are trying to prevent. You will need about 3 fl oz of Surflan per 1,000 sq ft area. Be sure you review the product label to make sure your desirable plants are listed as being tolerant to the product. Surflan products are known to be pretty thick and will likely clog a hose end sprayer so it is best to apply with a pump or backpack sprayer. The other problem with using the hose end sprayer for the Surflan application is that they are not very accurate and you can wind up dispensing more/less product than needed in a given area which can lead to less than desirable results. With pre-emergents it is important to apply the right amount of product over an area and water in so that it gets down to the soil to create the barrier.

Q

Is the Orange color in Surflan Pro Herbicide staining?
Like several other people I have a lot of stone in my Florida landscaping. Most of the rock is Medium White or Brown. Will the Orange color of Surflan Pro stain the whiter rocks or will rain wash it off over time??

A

Surflan Pro may cause a slight stain. If you start to notice a slight discolor, rinsing the rocks with water should remove it.

Depending on the type of weeds you have in your ground cover and the type of ground cover you have will depend on what product options may work for you. Without more specifics we cannot say for certain that the following products will get rid of what you have and will not harm your ground cover. You will want to check the product labels to ensure they meet your needs. For post emergent control (killing something that has already come up in your treatment areas) if the weeds are grassy you could use something like Grass Out Max or Fertilome Over the Top. This will only kill and target grasses coming up in ornamental beds. If you have broadleaf weeds, hand pulling or spot treating with roundup for post emergent control is about the only option. Broadleaf weed control products cannot be sprayed over the top of ground covers as they are broadleaf plants and will likely be harmed as well. For pre emergent control (preventing weeds/grasses from coming up through treatment areas) you have a lot more options to choose from. Surflan Pro/Surflan AS, Gallery 75 DF, Snapshot and many others would be wonderful options that you can use in spring and fall to help prevent persistant weeds from coming back throughout the season. Again, please check the product labels on each page to ensure that the weeds you are targeting and the ground cover you have are on the label as safe for use.

Q

Can I mix Surflan Pro with Anime 400?
Anime 400 is Dimethylamine salt of 2,4-dichlorophenoxyacetic acid - 46.47%. I purchased your Surflan pro. I would prefer using Glyphosate but I have a bunch of 2,4-D on hand already. I am looking to knock out broadleafs and prevent emergence as well.

A

The blend of Surflan Pro and Anime 400 would be a great mix to use for control of the broad leaf weeds. Make sure to not water it in for at least 24 hours and you will see great results. Please let us know if you have any other questions.

Can you use Surflan Pro Herbicide after the vegetable garden has been completely cleared of edible items? AZ
I have had a tremendous weed problem with my back yard. I spend most of the summer just getting the yard in some normalcy. I've tried everything in the book. Currently I'm spraying CLEAR which seems to work better than anything I've tried before but the problem still exists. I'm hoping for a solution. Thank you MB Greenway
