    5 of 5 Stars  Weed Impede
    By Mark on March 13, 2014

    Excellent product as long as you use it every 6 months as directed (in AZ that is in March and October). Be sure to water the applied area if it des not rain. I have 1.25 acres with almost no weeds when used as compared to my neighbors that have weeds all over. I am a life long user now!

May 16, 2012Phyllis from Chandler, Az asked:

QCan Weed Impede be applied with a watering can and if so how do I mix it?

A

The Weed Impede product label does recommend that you use either a handheld sprayer or a backpack sprayer to get even coverage and this would be our recommendation as well. The amount of Weed Impede you will use will vary depending on what weeds you are trying to prevent and what season you are treating in but in general you will need 1-12 fl oz per 1,000 sq ft of area to be treated. According to the Weed Impede product label:

"The amount of water used to apply WEED IMPEDE™ herbicide is not critical, but should be sufficient for uniform coverage of the target area. Calibrate by determining the volume of water required to treat 1,000 square feet. Use this calibration volume to determine the amount of water and WEED IMPEDE™ herbicide needed to treat the target area (see the following calibration example). Note: Sprayer calibration (volume of spray needed to treat 1,000 square feet) will vary with each individual operator.
Steps in Calibration:
1. Mark an area of 1,000 square feet (i.e. 20 by 50 feet or 25 by 40 feet).
2. Place the sprayer on a level surface and add water noting the final level of water in the spray tank.
3. Spray the marked area with a sufficient volume of water to provide uniform coverage. Refill the sprayer to the same level as before measuring the amount of water added. The measured water added to the sprayer is the volume needed to cover 1,000 square feet.
4. Determine the application rate (fl. oz./1,000 sq. ft.) for WEED IMPEDE™ from the Recommendations section of this label.
5. To each volume of water used as measured in step 3, add the amount of WEED IMPEDE™ as determined in step 4.
Example: If the sprayer uses 2 gallons of water to cover 1,000 square feet and the desired application rate of WEED IMPEDE™ is 3 fluid oz./1,000 square feet, then you would add 3 fluid ounces of WEED IMPEDE™ to every 2 gallons of water to be used."

QWhen is the best time to apply Monterey Weed Impede to control spurge?
We have established Tex Turf 10 Burmuda. We notice that the spurge usually appears in May-June.

A

Application timing will vary by region and the best person to ask about application timing is your local master gardener who works at your local cooperative extension office.

February 5, 2013Jim from Fresno, Ca 93727 asked:

QHow soon after application of Monterey may I plant a new lawn from seed (Fescue Mix)?

AAccording to the Weed Impede product label: Herbicides that control annual weeds may also affect establishment of desirable turfgrass seedlings. Reseeding should be delayed for at least 90 - 120 days following application of Weed Impede. With reseeding, it is essential that proper cultural practices such as soil cultivation and seedbed preparation, irrigation and fertilization be followed. For satisfactory reseeding results following use of Weed Impede, the seeding rate should be increased and equipment designed to play seed in full contact with soil (such as the Rogers Aero Seeder) should be employed.

QIs Monterey Weed Impede effective for basket grass?

AWeed Impede is not specifically labeled for basket grass.  One thing to note is that weed impede is a pre-emergent mainly labeled to keep certain type of turf grasses out of other turf grass and landscaped areas.  Are you looking to kill existing basket grass?  You should use a non-selective weed killer to eradicate basket grass, like our professional Eraser product.  This will kill anything it touches, like Roundup but stronger. So be careful where you apply it.

February 12, 2014Michael from Corpus Christi, Tx asked:

QI have a nut weed problem & ordered your Monterey Weed Impede, is this the best product to use?

AThe Monterey Weed Impede (Surflan Herbicide) is not labeled for nutsedge or nutgrass control. It does kill a large variety of other broadleaf weeds and is safe for many lawn types, but it would most likely not work for your needs. Nutsedge is a weed that requires a very specific treatment with products specificially targeted to that weed and not many others. Our Sedgehammer Herbicide is one of the best products on the market for control of Nutsedge.

February 20, 2012Bob from Martinton, Illinois asked:

QCan I reapply Impede on raspberries after the effectiveness of the dormant application wears off in mid-summer
I grow about 2 plus acres of red and black raspberries and have yet to come up with a weed control program that extends throughout the summer. Can I apply a second application of Impede during the summer without damaging the new canes?

AWeed Impede can only be used on plants listed on the product label that will not bear fruit for at least one year. Unfortunately raspberries are not listed on the product label of Weed Impede. We recommend you contact your local Dept of Agriculture as they are usually helpful in coming up with a product or a combination of products that can be used on specific crops.
