Prodiamine 65WDG: When, Why, & How Much To Apply! (it's too easy!) 

To make this really easy. I dont know why the use that .183 oz. The easy figure is 5.2 grams per 1000 sq ft. .183 oz = 5.2 grams. Im not sure what kind of scale the use that measures like that. Mine reads in grams and whole ounces. I have about 6000 sq ft. So i use about 31 grams of prodiamine in May and another 31 grams in july. Thats it. I live in Ohio so depending on your area on when to apply. Google gdd tracker and based on your zip it will give u the optimal time to apply crab pre emergent (prodiamine)

Thank you so much. I got the small bottle using your link and got a Military discount on a 5 gallon pack of Next products. Much respect for what you bring to RU-vid.

Funny, I just put down Prodiamine today in DFW arera, under the months graphs you showed from the label there is another table that shows maximum rates per year by grass type per 1000sqf, I divide the max rate per year by 2 since I do fall and spring application. It is easier to covert to grams (at least for me) , so the max rate fo Brermuda grass is 0.83oz that comes like 25grams divided by 2 for 2 split application, I used 12 grams per 1000sqf.

I definitely need to mark my bottle. Smart idea!

Very informative video! Thank you for breaking down the math!

We can use prodiamine in the fall when overseeing tall fescue?.is that what I heard? I thought if you were applying prodiamine that reseeding is a no no for a few months after applying. Am I wrong here? I thought that was the reason you don't use prodiamine when overseeing in the spring. Wouldn't it be the same in the fall and prevent germination?

Thanks for the breakdown, makes it simple to follow

The big issue is I have a Chapin backpack sprayer, and it's difficult to know how much water (rate of water) comes out of that sprayer.

Since I spray my 2 acres with a 25 gallon pull behind sprayer I use a lot of chemicals compared to the normal home owner. I used Lesco Pre-M in a split application for years with some mixed results. I have used prodiamine since 2019 when I bought a 10lb bag of it for $115 from my Siteone dealer. I used that up last year so I need to buy more but dam now I only can get a 5 pound container for a $115. Price has doubled 😳 I was using a mix rate of .80 prodiamine to a gallon of water or 20oz to 25 gallons of water for one spray in March here in Oklahoma. So a 5lb container will only give me 4 application at that rate. Using that .183 for 2 months ×3 roughly. 55 oz per gallon of water for a 6 month application maybe I will try that instead of the annual max rate. It's hard for me to do the split application because of weather and mainly wind. When that 2nd application is due It's normally to windy or I have to work. Lol I have been spraying my Bermuda acreage for over 15 years so I have fought that split application of Lesco Pre-M for many years. I prefer one application in March and done! 👍 If and weeds or crabgrass later in July or August I have the chemicals for that in my arsenal.

Will you be doing a video of when you actually apply the prodiamen or pre emergent?? I'm in the Piedmont triad western foothills... Still a little early but I wasn't sure. also I saw this product in granular ... Anyway enjoy your videos have a good weekend.

Hopefully u can answer quick lol. I reseeded and arated late September 24th . Could I still put this down or should I hold off? I'm not sure if the seeds are fully germinated and i don't want to kill it. I plan to reseed the side and frot of my house which ill use tenacity and fertilizer.

Subscribed just to say "Thank You" for this video. It would be so much easier if they just put it on the label for us " Math Challenged" people. 😂

How many TSP for 4 gallons?

Mr. F. If I use the Split Method and double the .183 which equals .366 oz. / 1000 sq. ft on my lawn will that cover 8 months of Crabgrass Prevention?

This is my first time using Prodiamine and unusual temps here in Minnesota. I treat 2 acres and cannot water it in manually. Last week soils temps were in the 40's and all of a sudden this week we had record heat. Monday-Wednesday were in the 80's and yesterday hit 91. Soil temp overnight showed 61 degrees. Next week the low will get just above freezing. Did I miss my window for putting this down? I have been waiting for rain in the forecast but no luck there either. Any help is appreciated.

Great info sir!

Great video Mr. F. For a 2 gal sprayer, what nozzle do you recommend or can I use the original product nozzle? tks Mark-Michigan

Great video

Gm Mr Furgerson. Which tip do you use to apply the Prodiamine?

I’ve noticed the yellow color when you spray. I have some decorative rock beds with some larger nice stones will this stain those rocks and stones yellow over time or once it waters in will the yellow go away? Thank you!

so the measurments you mentioned do not have anything to do with the gallons. I know its probably not wise to do very little water too but i have about 15K sq ft. should i split it into 2 4 gallon applications? I'm a fast walker but again i dont want to do it all in 4 gallons if its not effective??? is too much water bad is too little water bad. hope it makes sence. I do the granular but i would not mind just throwing the battery backpack on and walk my yard like i do with my herbecide spray applications.

How long after applying the prodaimine can you mow the yard? Want to wait a certain amount of days or does it matter?

I have a good amount of broadleaf weeds right now that came up with my fall seeding last year. I sprayed with Tenacity about 3 weeks ago and it's working to kill them. I also have several bare spots and overall feels like a thin lawn (tall fescue and perennial rye mix). I was thinking about seeding this spring (located in Winston), but I've read it's not a great idea for various reasons. Would you recommend using prodiamine pre emergent and only fall seeding for all lawns even thin lawns with bare spots or could I try to seed this spring and then start with pre emergent next year? I might be able to use tenacity as a pre emergent because I can use it while seeding, although I don't think it's as effective as prodiamine.

I've heard kids/animals should keep off of it until it's dry. But if it's going to be a few days before rain, should they be kept off of it until it gets watered in, or just until the initial application itself is dry (Google says 3 hours?)

I'm thinking of getting a flowzone typhoon with the nozzle buddy. How is it possible to put out 8 gal worth of product with only 4 gallons lol. Thanks

In Alabama crabgrass hit in early early March

Just quick question, how much water per .183 ounces ? Thanks

What's the .55 you see in the statistics?

Who is Mr. Ferguson? Do you call yourself in the third person is that it?

Will it harm bushes, trees and flowers?

Thanks for the clear and simple instructions. I do wonder about the amount to purchase as several products containing that active ingredient state that it loses its strength after three years. My lawn is about the same size as yours so it will take me years to use that large of a jug of it.

After I put down the Prodiamine can I then put down a turf builder, like scotts?

It was rough listening to you talk. Just get to the point.

I'm 81, please help leaving out small talk. No offense please. St. Augustine. I'm in Memphis 95 latitude. It takes 2 1/2 trailers like yours to cover my 1.44 acres. I spray in Fall & Spring. Please tell me how much 65 WDG prodiamine to put in my 25 gal sprayer. 𝗦𝘂𝗿𝗲 𝘄𝗶𝗹𝗹 𝗮𝗽𝗽𝗿𝗲𝗰𝗶𝗮𝘁𝗲 𝘆𝗼𝘂𝗿 𝗮𝗻𝘀𝘄𝗲𝗿
