Product Description:
Prodiamine 65 WDG is a professionally formulated pre-emergent 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.

Most DIYers use this product in spring to stop crabgrass. Crabgrass is an annual grassy weed that germinates in spring, grows lime green and large during summer, then, towards the later fall, drops seeds. The following spring, the process starts all over again. This is why crabgrass is called an “annual” grassy weed. The good news is that it can be stopped very effectively using this product.

The best time to apply Prodiamine is in the spring or fall, as soil temperatures are between 55F to 70F. This will give you approximately 3 months of pre-emergence protection.

FOR LARGER LAWNS, you can purchase a five-pound bottle here.

Application Information:

  • For cool and warm-season lawns, our recommendation is 2 applications in the spring if your target is crabgrass. Check out our FREE Pre-Emergent Guide for specific details.
  • The best time to apply Prodiamine is in the spring or fall, as soil temperatures are between 55F to 70F. This will give you approximately 3 months of pre-emergence protection. Download our FREE app it will tell you exactly when your soil temps cross these milestones.

TireJECT cannot work miracles
Size: Compact Car, Mid-size Sedan, Size: Compact Car, Mid-size Sedan
TireJECT is a surprisingly thin fluid that supposedly contains fibers that must help stop up holes. Frankly I'm still confused as to how this stuff can plug a leak, but apparently it does. Tons of reviews say so. I say apparently because the product did not completely stop a slow leak in my tire, but that's OK. I knew it likely wouldn't. I'll have to replace the tire unfortunately. I had a garage install four nearly-new tires on my car. After installing, a heavy leak was discovered in one of them. They took the tire off again and found a small tear near the rim/bead of the sidewall. Since the tear would be flat against the rim, they suggested to let them try and repair it with tire patch adhesive and lots of bead sealer. They were confident, so I went for it. It seemed to work, but it went flat a few days later. TireJECT seemed like the perfect solution to the slow leak since I wouldn't have to disturb the repair. I bought the kind without the syringe and regretted it immediately upon trying to use it. First, the valve stem removal tool broke as it loosened it. I had to buy a new tool down the road. When I went to inject, I squeezed as hard as I could but it just wouldn't flow past the TPM. It also kept leaking out of the flex joint of the nozzle. I had a huge syringe on hand, so I sucked up the rest from the bag, ziptied the hose on both ends and got the rest of the product into the tire. HURRAY! The tire pressure had fallen considerably by the next morning. BOOOoo. I contacted TireJECT, and after several emails (and long waits in between). They determined their product was not suitable for my use case. They refunded what I paid without me even asking. I really appreciated that. That said, before injecting, the tire would go flat overnight. So, TireJECT does work to a good degree. I'm half tempted to overdose the tire with another package. Give TireJECT a try! Though, be sure your situation matches their criteria. If you have a TPM, opt for the package that comes with a syringe. You will need it. Also, throw the cast pot metal, tire stem tool out and get a decent machined one before you do the repair. Thank me later.

Works once again!
Size: Compact Car, Mid-size Sedan
Third time using TireJect on a vehicle, and it's worked perfectly each time. First was the off-road formula for leaking motorcycle tire beads.... then this formula my light SUV with a slow leak until I could get the tire replaced. This was for a stubborn tire that had a leak SOMEWHERE, and usually would lose 10-15 psi overnight after a fill-up. Two days later, still fully inflated and no signs of trouble. This is great because this formulation is also okay for tire pressure sensors. Will continue to purchase this product for similar issues going forward. High quality, durability, and easy to use.

Works like a champ!
Size: Full-size Truck, SUV
It works great! I had one fairly slow leak and 2 very slow leaks. 3 Tires. 2 were on my 94 Ford Ranger. I put a little more than 1/2 the packet in my fastest leaking tire (on the Ranger) and about 1/4 of the packet in the 2nd tire of the same vehicle. Lastly, I put the final 1/4 in a very slow leaking tire on my 2000 Ford F-150. All tires have stopped leaking!! I am delighted with the effectiveness of this product!!

Seems to have done a great job.
Size: Full-size Truck, SUV (2-pack)
One of our cars has suffered from rim leaks and was driving me nuts. Constantly being asked by my wife to top off the tires on her car. When I replaced a damaged rim I asked the tire shop to look for the source of the leaks. They said the "alloy" rims had started to corrode and did their best to get them to seal but warned me they would likely leak again. This spring when I removed her snow tires I found 3 of her 4 tires had gone completely flat in storage. The fourth was the new rim which was fine. I considered buying new rims that won't have this problem but wanted to wait until her times need to be replaced. The batteries in the TPMS sensors are getting very low so likely these will need to be replaced as well. I thought to try some sort of sealant. Most of the products I saw were not rated for automotive systems and offered warnings about risk to the TMPS sensors. This seemed to be the only product rated for my application and claimed it would not harm our car's sensors. So I gave it a shot. I ordered the SUV package that came with an injector and two 8-oz bottles. I put 4 oz in each tire per the instructions. Overall the process was easy except the valve core extractor broken on one of the tires. I had to pick up a replacement at a local auto parts store. Also, injecting the sealant creates a small amount of pressure in the tire that, if one doesn't release by drawing out the plunger, will burp a small amount of sealant onto the rims. Fairly easy to clean up with WARM water and easier to avoid after the first experience. Drove the car around at a variety of speeds for 10-15 minutes (had errands to run) and waited to see what happened. Great results. Weeks later and the tires still have the correct pressure. I am not sure how long this will last but hopefully for the remaining life of the tires at least. I took one star off for easy of use / easy to install because the valve core extractor is made of extremely cheap aluminum and I am sure others will have a poor experience with it. Be forewarned and consider buying one before you start jacking up your car and letting the air out of the tires only to find you break the tool on a sticky valve core and are unable to complete the job without a trip to the auto parts store. I'll update this review in about a year to report on the long-term outlook for this product.

It Works!
Size: Full-size Truck, SUV
When I bought my vehicle it didn't come with a spare. I knew what I was in for. I was on my way to an important meeting and as fate would have, the tire pressure indicator reported a flat. I imagined the worst but experienced the best! The directions said to let all the air out of tire and remove the valve stem core, it seemed like I was making a bad situation worse. Then it said to attach the tube to the stem and squeeze the contents into the tire. I thought "this is never going to work" the fluid seemed too watery to seal anything, but I followed instructions, I reinstalled the valve core and reinflated the tire, and it worked! I expected it to leak immediately, it didn't. It lasted all day and most of the next day until I could get the tire to the shop. They removed a nail and patched the hole, overall I'm very satisfied, I bought a replacement right away, just in case!
