Prodiamine 65 WDG is a professional-grade pre-emergent herbicide containing 65% prodiamine. It creates a weed-control barrier in the soil that prevents susceptible weed seeds from successfully developing after germination.
Always follow the Prodiamine 65 WDG label for application rates, approved turf types, target weeds, and annual application limits.
For most lawns, the best time to apply Prodiamine pre-emergent is spring and fall, before target weeds germinate.
Spring application: Apply before summer annual weeds such as crabgrass and spurge begin germinating. A common guideline is to make the application before soil temperatures consistently reach approximately 55°F.
Fall application: Apply before winter annual weeds such as annual bluegrass (Poa annua), chickweed, and henbit begin germinating as soil temperatures cool.
For the best results:
Because soil temperatures vary by region and weather conditions, spring and fall application dates can differ significantly from one location to another.
Yes. Prodiamine 65 WDG is labeled for use on established Bermudagrass and is a popular option for preventing crabgrass and other annual weeds in Bermuda lawns.
Prodiamine can be especially useful in Bermudagrass because it provides:
If you are looking for the best pre-emergent for Bermuda grass, Prodiamine is a strong option when the weeds you need to prevent are listed on the label.
Prodiamine 65 WDG is labeled for use on many common established warm-season and cool-season turfgrasses, including:
Application rates and restrictions can vary by turf species. Refer to the Prodiamine 65 WDG label before treating your lawn.
Prodiamine 65 WDG provides pre-emergent control of many annual grassy and broadleaf weeds, including:
For the complete list of controlled weeds, consult the current Prodiamine 65 WDG label.
Yes. Prodiamine 65 WDG is labeled as a pre-emergent herbicide for spurge, including prostrate spurge.
For effective spurge pre-emergent control, apply Prodiamine before spurge seeds germinate. A spring pre-emergent application before soil temperatures consistently rise above approximately 55°F can help prevent spurge that typically appears as temperatures warm.
Prodiamine will not provide effective control of mature spurge that has already emerged. Existing weeds generally require an appropriate post-emergent herbicide.
No. Prodiamine 65 WDG should be used as a pre-emergent weed preventer.
It works by creating a barrier in the upper soil that interferes with the development of susceptible weeds as they germinate. If crabgrass, spurge, Poa annua, or another weed is already established, an appropriate post-emergent herbicide may be needed.
For season-long weed management, Prodiamine can be used for pre-emergent prevention, while a compatible post-emergent herbicide can be used to control weeds that are already growing.
Yes. Prodiamine 65 WDG should be watered into the soil after application so the herbicide can form the pre-emergent barrier needed to prevent weeds.
After spraying:
Without adequate rainfall or irrigation, the herbicide may not be properly incorporated into the soil and weed prevention can be reduced.
Rain after applying Prodiamine can be beneficial because the product needs moisture to move into the soil and activate the pre-emergent barrier.
Approximately 1/2 inch of rainfall or irrigation after application is generally desirable. However, extremely heavy rainfall may cause runoff or move product away from the intended treatment area.
If very heavy rain is forecast, it may be better to apply when you can more reliably control the amount of water used to incorporate the herbicide. Always follow the product label regarding application and watering requirements.
The amount of Prodiamine 65 WDG per 1,000 sq. ft. is more important than the number of gallons of water used to apply it. Water primarily acts as the carrier that distributes the herbicide evenly over the treatment area.
Application rates vary based on turfgrass, target weed, and desired length of control. The product label provides the appropriate rates and maximum annual amounts for each turf species.
For small lawn applications, 1.5 level teaspoons per gallon of water to treat approximately 1,000 sq. ft. is a commonly used mixing guideline. However, you should always calculate the actual amount of Prodiamine needed based on the labeled rate for your turf and treatment goal rather than relying solely on a teaspoons-per-gallon ratio.
Prodiamine 65 WDG is a water-dispersible granule, so it must be mixed with water before spraying.
For an even application:
Easy to use for First timer!

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

Prodiamine 65 WDG Is a Blessing to my Centipede
By Anonymous on 06/10/2013

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!!!!!

Lawn treatment for Fox tail and crab grass.
By Ray 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.

Prodiamine 65 WDG

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-.55 oz of product with for each 1,000 sq ft area that needs to be treated.

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?
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."
