User questions & answers

Question:	Can hose end (not tank) sprayer be used assuming correct oz/1000sf are applied?turf must be irrigated anyway so no dilution issue
Answer:	Correct I have used both spray tank 2 gal and hose end sprayer. Hose end much faster and again correct you have to "wet" the product in or off the grass to create a "weed seed blocking germination". Only need 2 oz I believe per gal. This stuff WORKS . HOWEVER I have bought it on Amazon for $32 per qt NOW is shows $72 per qt. HOLY CRAP what happened to price?
Question:	can this be used over juniper or will it kill it
Answer:	Sorry, never used it over juniper, strictly on desert landscape. It usually does not affect green, growing plants; just prevents seeds from germinating and thus no weeds come up.
Question:	Walter: What ratio do you use? Many thanks
Answer:	1.5-3 oz per 1000 sq ft. Which means if your spraying 2 gallons per 1000 sq ft you would add 1.5-3.0 oz per 2 gallons of water.
Question:	will this product kill my bahia grass
Answer:	No. Surflan is a pre-emergent herbicide for preventative control of grassy and broadleaf weeds. Bahiagrass is not controlled preventatively or curatively. you can use a herbicide with metsulfuron 60Df as the active ingredient for controlling bahia grass.

User questions & answers

Question:	It is ok to put Weed and Feed after putting this product but before 30 days are over. Says at the back to wait for 30 days before another application
Answer:	You would want to wait the entire time before applying another product with fertilizer. If you have broadleaf weeds now, you can spot treat with Ortho Weed B Gon.
Question:	I just applied Crabgrass preventer. How long must i wait to lay down seed to grow grass
Answer:	In what I’ve read before, 6-8 weeks. At that point you should wait until fall, which is there ideal grass time in most climates. It gives the grass a chance to start growing on top, then winterize and grow strong roots so that spring will be awesome. About 3 years now I’ve been applying this strategy and find my grass is greener than all the neighbors. There is one neighbor who has a thicker lawn but he has a different slope in his yard and has been at it much longer. I will overtake him!
Question:	How soon can I throw down some new seed? I would like more kentucky blue in my lawn
Answer:	you have created a force field. only way is to put down new loam 1/2'' thick then seed . late august aerate lawn then seed,& do it like your feeding the chicken & those hens are hungry. next year you will not believe, keep your deck clean & blades sharp. GOOD LUCK
Question:	Okay to use in August
Answer:	I have Poa Annua and have been doing a lot of research on it. Many websites with information about Poa Annua say for effective control, besides Spring treatment it is good to put pre emergent down in August/September. Here is a quote from the Purdue University Extension website: "Poa annua is a winter annual that germinates in the late summer/early fall once soil temperatures fall below 70o F. Seedlings mature in the fall, overwinter in a vegetative state, and flower and produce seed in late spring and early summer." I just chatted with Scott's website and they said this product can be effective when used in this manner. I plan to apply it then AND next Spring. Most of the lawns in my development have been taken over by Poa Annua but I am still fighting the fight and hope to win or at least keep it to a minimum.

Get An Early Start This Spring

Protect your lawn all season long against listed weeds, including crabgrass, all while feeding for a fast green-up after winter.

When To Apply To Prevent Weeds

Apply in early spring to prevent the germination of crabgrass, chickweed, poa annua, and other common lawn weeds, before they start to spread. Apply before the 3rd or 4th mowing to protect all season long.

Tips For Lawn Care Success

First, regular feedings help your lawn look it’s best and provide the nutrients it needs to withstand the stress of weeds, weather and activity. Secondly, after you mow leave the grass clippings on the lawn. This allows grass to use water more effectively. Finally water, utilize nature’s sprinkler as much as possible. When you do have to water, do it between 6 and 10 am - less water is lost to evaporation and more reaches the roots.

Product description

Prodiamine pre-emergent herbicide in water dispersible granule formulation. This is a 5oz bottle made specifically for DIYers who want small quantities of this professionally formulated pre emergent herbicide to be mixed in water and sprayed out as a liquid. Yard Mastery is proud to bring this to market specifically in a smaller bottle for DIYers. #DIYfirst Prodiamine is a pre-emergent used in spring and fall to stop problem grasses and weeds in lawns. It is best known as a crabgrass and poa annua pre emergent but is also stops other listed weeds including: Barnyardgrass, Carpetweed-04, Chickweed (common), Chickweed (mousear), Crabgrass (large and smooth), Crowfootgrass, Cup grass (woolly), Foxtails (annual), Goosegrass, Henbit, Itchgrass, Johnsongrass (seedling), Junglerice, Knotweed, Kochia, Lambsquarters (common), Lovegrass, Panicum (browntop, fall and Texas), Pigweed, Purslane (common), Pusley (Florida), Rescuegrass, Shepherdspurse, Signalgrass Broadleaf, Speedwell (Persian), Sprangletop, Spurge (prostate), Witchgrass, Woodsorrel (yellow, from seed) Since this is a professional formulation, there are several ways to parse the usage and rates. Our recommendation is to apply two applications in spring for crabgrass, known as “split applications” and each of those should be .183oz/1000 sq ft (5.2g). We recommend weighing product on a scale to be accurate and grams will be the easiest. Mix 5.2 grams of prodiamine 65 WDG in 1 gallon of water and this spray mix can cover 1,000 sq ft.

• 5OZ BOTTLE - Professionally formulated for DIYers who want small quantities of pre emergent. Enough for 1 entire season on a 10,000 square foot yard.
• STOP CRABGRASS - Use this in spring and fall to stop crabgrass and poa annua as a pre emergent but this also stops other listed weeds. See full product description below.
• WATER DISPERSIBLE GRANULE (WDG) - Mix in water and sprayed out as a liquid via pump or battery sprayer. Product must be watered in.
• SPRING AND FALL APPLICATIONS - Mix .183oz or 5.2 grams of prodiamine 65 WDG in 1 gallon of water and this spray mix can cover 1,000 sq ft.
• FOR ALL GRASS TYPES - Ok On Kentucky Bluegrass, Perennial Rye, Turf Type Tall Fescue, Bermuda, Zoysia, St Augustine, Centipede and Bahia Grasses.

User questions & answers

Question:	How often do you need to apply this treatment
Answer:	As often as you want as long as you do not go over the maximum amount for your turf type per year. For some turf types, that is about .83 ounces by weight of this dry granule per 1,000 sq. ft. Most typically people apply this in the late winter or early spring. Many say to put this down when the soil temps are at 55 degrees in the winter/spring, but that is when crabgrass starts to germinate. Many lawn care professionals say to put this down earlier, when the temps are 40 to 45 degrees because it is the bacteria in the soil that break down the product and at these temperatures, the bacteria are pretty much dormant. You apply at 0.185 ounces by weight per 1,000 sq. ft. (for any grass type) and that will give you 3-4 months of protection when put down at those temps above. Put down 0.28 ounces per 1,000 sq. ft. to give 4 months of protection in the fall. I apply when the night time temperatures start dropping into the low 70's and upper 60's. I saw someone say you want this down before the soil temperatures drop to 70 in the late summer/early fall, but I have not confirmed this. So if the day temps are in the 80's and 90's and the night temps are in the 70's or upper 60's, you should still be ahead of the annual weeds you're trying to prevent in the fall.
Question:	Is this product safe for centipede grass thats 1 year old
Answer:	This should be safe on any established grass which typically means the grass has grown enough to be mowed 4+ times. You can put it down a little earlier depending on the grass type, but better safe than sorry. If you put this down too soon you can harm the new grass while it is maturing and if you do this, the prodiamine will stop new grass seed (as well as weeds) from germinating for a few months.
Question:	Will it prevent crabgrass
Answer:	Yes. Prodiamine is broken down by the microbes in the soil, and the microbes do not really start to become very active until the soil temperatures are higher...like 50+ degrees (not 100% positive of what temp here, but you get the idea). Crabgrass seeds start to germinate once the ground temperatures start to reach about 55 degrees. So you can put this down when the ground temperatures are 40-45 degrees and it will still be very effective once the ground temperatures reach ~55 degrees and provide the protection you need, versus waiting until the ground temps are already at 55 degrees and you may be too late. What this does it once the crabgrass and other seeds start to germinate, Prodiamine will stop the roots from progressing once the seeds start to germinate, which kills the plant before it completely germinates and breaks through the soil. What I like to do (heard this from a lawn care professional - YouTube channel 'Pest & Lawn Ginja') is get use a cheap meat thermometer and check the soil temps and once the ground temps are around 55 degrees, put down a different pre-emergent called Dithiopyr. This will also stop seeds from fully germinating as the Prodiamine does, but Dithiopyr also acts as a post-emergent for very young weeds and crabgrass up to 2-3 tillers. So you get early protection and a second layer of protection if required.
Question:	will it work with no pre mixing sprayer connected to water hose? if so, is setting of 2tsp for one gallon will work
Answer:	I wouldn't recommend it. Prodiamine, straight out of the container, is in granular form. Each granule is about 1 mm in diameter. All the hose end sprayers I know of require dispensing of the product as a liquid. For my application, which is to treat for Annual Bluegrass (Poa Annua) in a Zoysia lawn, I used a 3 gallon backpack tank sprayer. I measured 3/4 Tbsp. Prodiamine and poured it into a quart container. I then added 3 cups water and mixed the two together into a concentrate. I then poured the concentrate into the backpack tank sprayer and added water to make 3 gallons. 3 gallons will treat 750 sq. ft. The amount to use is 1/4 Tbsp. Prodiamine per gallon of water. Each gallon will treat 250 sq. ft.There are 3 tsp. in a Tbsp.

User questions & answers

Question:	Just reseeded by Bermuda lawn last week. Is this ok to use or should I wait
Answer:	I would wait. Barricade prevent any seed to germinate.
Question:	Has anyone used this in the fall to prevent crabgrass the next spring? I've seen it recommended that way for other weeds but not for crabgrass
Answer:	From what I understand, you need to reapply as per directions, due to Crabgrass germination process from early spring to mid to late summer, depending on weather conditions. This product is a "pre"emergent,so to be effective, apply to kill weed seeds before they can germinate.

Question:	what is the Nitrogen value in this product? not seeing it on the label
Answer:	This has zero Nitrogen. This is a granular pesticide product. It does not contain any NPK.

Prevent Weeds All Season Long

Barricade is The Andersons professional-grade pre-emergent weed control. Containing 0.48% of the active ingredient prodiamine, Barricade is one of the best and most cost-effective granular weed preventers on the market. It can be used on established lawns and landscape beds to prevent over 30 grass and broadleaf weeds like crabgrass, goosegrass, foxtail, lambsquarter, henbit and more.

Barricade features The Andersons patented Dispersible Granular (DG) Technology which allows each granule to disperse into thousands of micro particles after coming into contact with water. Because of DG Technology, Barricade can move past the thatch layer of your lawn and into the soil where it prevents the germination of weed seeds.

When To Apply Barricade - Spring and Fall

Barricade is a pre-emergent weed control, which means that is designed to prevent weeds. Application timing is critical to the product's performance.

To prevent summer annual weeds in both northern and southern turf types, apply Barricade in early spring prior to soil temperatures reaching 55 degrees Fahrenheit at a four inch depth. Applying at this time will prevent weed seeds from germinating.

In southern zones, Barricade can be reapplied in the fall to prevent annual winter weeds like poa annua, also known as bluegrass.

Remember, Barricade must receive irrigation or light rainfall of at least .05 inches for the herbicide prevention to activate.

Barricade and Seeding

In the same way that Barricade prevents the germination of weeds, it can also inhibit the germination of turf.

If you already seeded wait 60 days or until after the second mowing, whichever is longer, before you apply Barricade.

How long you should wait to seed or overseed after applying Barricade depends on your climate. Refer to the table below for recommended intervals.

User questions & answers

Question:	Does it prevent crabgrass
Answer:	Yes - this product is very effective in the prevention of crabgrass and other weeds as listed on the product label.
Question:	Can this be used on Zoysia Grass
Answer:	Yes this may be used in established Zoysia.
Question:	What are the spreader settings for a scotts edge guard spreader
Answer:	It varies depending on how much of a coat you want to apply. The pictures on the page show that the edge spreader can range from 4 to 7.5
Question:	When should I put it down
Answer:	In the late winter or early spring. Crabgrass and other annual weeds that you are trying to prevent often germinate after several days with soil temperatures (NOT air temperatures) being around 55 degrees. The microbes in the soil are what break down this pre-emergent and since microbes in the soil are fairly dormant in cold weather, that means you can put this down early, well before the soil reaches 55 degrees and the pre-emergent herbicide will still be active when the soil reaches the temperatures where annual weeds start to germinate. This does not kill the seeds, it stops root development as the seeds germinate so the weed/plant does not reach a stage where it will emerge from the soil and grow. Many lawn care professionals put down their pre-emergent herbicides when the soil temperatures are in the 35-45 degree range to prevent weeds. Oddly, I have yet to see anybody state an actual temperature for the soil as a guide to apply pre-emergence herbicides in he fall...? Keep in mind this will prevent plants from growing, so if you are planning on putting down new grass seed or overseeding to thicken growth in your lawn, this will also prevent desirable plants and grass from germinating as well.

User questions & answers

Question:	Can you apply this product during October to mature crabgrass and will it have any affect on it since we are in fall season and winter right around co
Answer:	Dimension is primarily a pre-emergent herbicide. However, it does have post-emergent effects on crabgrass (large, smooth, and southern species) during early crabgrass seedling growth following emergence in the spring, according to the label. I would be skeptical about its ability to control mature crabgrass. With the demise of MSMA, quinclorac (Drive 75, Drive XLR8, or generic quinclorac from Quali-Pro) seems to be the preferred weapon of choice for crabgrass.Check out the Dimension 2EW label - it has a section on crabgrass control: http://www.cdms.net/ldat/ld7ND010.pdf.
Question:	Does it treat Sand Spurs
Answer:	It's labeled for sandbur if that's what you mean.
Question:	If I put down this pre-emergent, how long should I wait to re-seed? Can anyone check their Dimensions bag and let me know? Thanks
Answer:	From the Dimension label: "Reseeding, overseeding, or sprigging of treated areas within 3 months after a single application or within 4 months of a split application (spring/fall) totaling more than 0.73 oz./1000 square ft. (2 pts./acre) may inhibit the establishment of desirable turfgrasses. However, overseeding with perennial ryegrass 8 weeks after an application, if slight injury to perennial ryegrass can be tolerated is a recommended exception."In practice, besides the rate, it depends on how heavy the soil is and how much rainfall you get. It is more mobile in more porous soils and with more rainfall. It also moves horizontally with runoff from heavy rainfall, concentrating in areas where water pools, but this doesn't prevent Bermuda and especially zoysia from spreading into those areas.
Question:	can it be used on post emerged crabgrass in Summer
Answer:	It won't kill the crabgrass that is already growing. However, it will prevent the crabgrass seeds released in the summer from mature crabgrass from germinating. Spray in March to control crabgrass through May, then spray again in June to carry over to September. You can then safely overseed (fescue) in Sept or Oct.

Question:	Can you seed after you lay this product
Answer:	google kudzu and learn how it was introduced into north america and spread through its use as a soil stabilizer during road building projects during the depression. it is an invasive species. repeated applications of Bonide should keep it in check - but it may be a long battle. be careful not to spray Bionide on desired species.
Question:	It’s a factor for dandelions
Answer:	Maybe once a month. It takes longer then roundup to see results. Almost 2 weeks but nothing comes back and I use half as much toma gallon vs. roundup. I like it much better.
Question:	Does this come with a shaker, or do you need a spreader to use
Answer:	No, it kills anything you spray at. So be careful when you spray weeds

User questions & answers

Question:	Can this be used with a hose end sprayer
Answer:	I have not used this product yet so can't specifically answer. Generally, any product can be used with a hose end sprayer if it is in liquid form and can pass through the nozzle where the product is mixed with the hose water. The water flow creates a vacuum that sucks the product from the sprayer container. If the liquid is too dense, the vacuum is not strong enough to suck it through. I use a type sprayer where you set the water flow to get the right mix. On thicker higher concentration products, I sometimes have to dilute the product and use a higher water setting to suck the product through the nozzle. This is not ideal when you are spraying something where the spray can drip off because you are spraying longer, and using more water, to get the same amount of product on what you are spraying. This is a lot of effort for a powder but would work under the above conditions. Frankly, had I realized this was a powder I would not have bought it. If I had a conventional hose sprayer, I would not buy it. There are too many unknown variables.
Question:	Do you mix prodiamine 65 wdg with water and spray
Answer:	Yes. Prodiamine 65 water dispersible granule (WDG). It is concentrated. You mix it with water and spray.

Question:	Did i read the application rate correctly? 1.5 tsp= .4 oz per 1000 sq ft? I found 1 Tbs = .5 oz
Answer:	3 teaspoons = 1 tablespoon. 2 tablespoons = 1 ounce, and 6 teaspoons = 1 ounce. It takes VERY LITTLE of this product to properly apply on a lawn. Unless you have a massive lawn, this bottle will last you years. This is a great value though. I just received an email from a guy I subscribe to on YouTube and he was selling a small bottle of Prodiamine for $20 and change, but it was so little it was nuts! It was only enough to do 3 applications on a 1,000 sq. ft. area. Just be sure you understand the directions. That 0.4 ounces per 1,000 sq. ft. is the amount you can apply per year (and you want to apply in a minimum of 2 times, if not 3, applying a split application after you aerate the lawn). that is off the top of my head - don't trust my memory though, read the label. Seriously, a little goes a long ways. This works well when applied properly. I bought this last summer and have applied once to date, and my Zoysia lawn is currently dormant which means it is a golden tan color, so any live weeds or undesirable grasses easily stand out. I have a 5,000 sq. ft. front lawn, and I only have about 25 sq. ft. of undesirable grass, and about 20+ sq. ft. of that is perennial grass that I need to kill off with glyphosate. The rest are either weeds that may have already germinated before application, or I am human, and I may have missed a few spots when I sprayed, or they are perennial grasses/weeds that were already established. This stuff is great! Oh, again, read the label. Different types of turf can tolerate different amounts of Prodiamine. My Zoysia can tolerate nearly twice as much as my neighbors Fescue lawn for example.
Question:	Is this effective on dandelions as a pre emergent
Answer:	Yes... but it works best using it consistently over time.
