    5 of 5 stars  Prodiamine 65 WDG Is a Blessing to my Centipede
    By in Newton Grove, NC on 06/10/2013
    Verified Purchase

    I sowed my grass in April of 2012. It was used for crops prior to building a house and seeding. I had the ability to water and thankfully received a good amount from the Big Man. However, I kept noticing that the highest part of my yard, didn't come up as expected. Crabgrass outgrew the centipede so I was left with a major problem. In March of 2013 I applied Prodimine 65 WDG to prevent the crabgrass from coming up. It worked great!!!!!! The spaces where my grass hadn't came up, were now dead and the centipede was able to grow across. My yard is not fully covered, but should be by the end of the growing season. If I hadn't sprayed, the crabgrass would have came up and the centipede wouldn't have been able to spread like it did. I used about 1 pound per acre. In the lower parts of my yard the centipede came up really good last year. As I speak, the crabgrass is starting to come back in the lower part because it is very heavy and fertile soil. You could literally grow anything on it. I wish I would have applied the whole 2 pounds per acre so I would have had a residual of approx. 8 months. Lesson Learned. I highly recommend to anyone who is having a weed problem. I am a happy customer!!!!!

    5 of 5 stars  Easy to use for First timer!
    By Lg in RVA on 03/14/2017

    Research enough on this stuff to be an expert. Conversion was easy when using Google. I used a little pill cup with tablespoon, ML, oz markers to properly mix the product. Took the average of the label recommendation @ 0.185-0.55o oz per 1000 sqft. Came out to ~ 10 ml per 1000 sq ft in 2 gallons of water. Took 3.5 refill @ 2 gallons of my E-sprayer. But was done in <1 hour for 7K sq ft yard. It rained the next 2 days so hoping to see no crab grass or other weeds when April hits

    5 of 5 stars  Lawn treatment for Fox tail and crab grass.
    By Ray in Lincoln, NE on 04/10/2016

    Used this for the first time spring of 2015. Mixed 4 oz. per 15 gallons in my sprayer. Laid out the yard in 1/4 acre sections using google earth. Have been fighting fox tail for years. After using Prodiamine had no weeds in the treated areas. Didn't do another application in late July like I should have so had some fox tail show up in the fall. In 2016 will do two applications and plan on great results.

    By Rick in Chico,CA on 09/29/2017

    I used this for the first time last Spring and was pleasantly surprised to have very few weeds for the entire season on all of the problem lawns I maintain. It's now almost October and I have seen very little Crabgrass,Spurge or Oxalis. I also like that it doesn't have obnoxious fumes while spraying as my 2nd favorite preemergent does.

    By J. in Northern Virginia on 05/13/2017

    I have used this product for several years and it has done a great job of controlling summer weeds and crabgrass in lawn areas. I use a 25 gallon spot sprayer so it takes about a day to treat about 4 acres. I have found that it is best to premix the product . It is also important to keep the tank mix agitated.

    By Charlie in Oklahoma City, Ok. on 09/05/2016

    Received the product in a timely manner. Searched the internet as to how much to mix for my smaller yard. I mixed 2 tablespoons with 4 gallons of water and spread it over 1000 sq. ft. Don't know the results yet because it has not turned cooler yet in my area. Didn't hurt the grass. Hope for the best

    5 of 5 stars  Effective Pre-emergent
    By William in chesterfield, va on 08/25/2016

    Have been using Prodiamine 65 WDG for the last 2 years and it has done a phenomenal job. Although a few weeds pop in-between applications, they are easy to just pick out myself and toss in the dumpster. The alternative of using a post emergent every 30 days is a poor way to control weeds and crab grass.

    By Chelly in North Central Ohio on 06/29/2016

    I decided to purchase this product based on all of the good reviews we saw here & on other sites. We made the right decision! Not one blade of crabgrass. Not one weed at all! It's been a little over over 6-7 weeks since application and we are getting all kinds of compliments on the yard this year! Someone told my husband that he didn't deserve me while talking about the yard. LOL Very easy to apply with my new trailer sprayer!

    By Matt in Houston, Texas on 04/29/2016

    I follow Randy Lemmon's schedule in caring for my St. Augustine (Raleigh) yard. His schedule calls for applying Barricade 3x a year. After several years, the difference along my property line compared to the neighbors is night and day...nearly no weeds at all, just wild Bermuda that we all fight down here.

QWhat is the correct dilution rate for Prodiamine 65 WDG?

A

The first thing you need to know when using an herbicide such as Prodiamine 65 WDG is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. You will need to use 0.185-0.55 oz per 1,000 sq ft . To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 0.185-.055 oz of product with for each 1,000 sq ft area that needs to be treated.

QPump Sprayer Calibration Needs to Use for Application
What are you looking for when applying the diluted granules for spray pattern from the pump sprayer as the liquid leaves the wand? What does the calibration require on round-up-style pump sprayer or similar? Is the calibration in regards to the use of "mist-style" spray pattern or "stream-style" spray pattern?

A

Calinbration does not refer to the spray pattern used to apply herbicides. Although, we would recommend using a mist stream. You would 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 Prodiamine 65 WDG 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 Prodiamine 65 WDG from the Recommendations section of this label.
5. To each volume of water used as measured in step 3, add the amount of Prodiamine 65 WDG 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 Prodiamine 65 WDG is 0.185 - 0.055 oz/1,000 square feet, then you would add 0.185 - 0.055 oz of Prodiamine 65 WDG to every 2 gallons of water to be used."

QWill Prodiamine 65 WDG be effective to prevent weeds in rock gardens?

Yes Prodiamine 65 WDG would be a great product to use as a pre-emergent in rock bed areas, you would just need to use a higher water volume to ensure the product gets past the rock to the soil beneath it where the seeds would be germinating.†
