Details 

For optimum results in turf, it is best to apply Surefire Propyzamide 500 SC Herbicide prior to germination or to young, actively growing winter grass plants in Autumn / early Winter.  Propyzamide is a systemic herbicide that is absorbed by the roots and translocated throughout the plant.  Therefore, immediate irrigation with 12 – 25 mm of water is required to move the chemical into the root zone. Follow-up irrigation with 12 – 25 mm is required 24 hours later. This amount of water is not solely used to incorporate the propyzamide into the root zone, this amount of water also facilitates the essential need to solubilize the propyzamide, without total solubilization of the active means the plant can only absorb less than a lethal dose of propyzamide – resulting in poor efficacy.  Best results are obtained by applying the product to cool, moist soil

When used in Turf, Surefire Propyzamide 500 SC Herbicide works by stunting the growth of Winter Grass, particularly the germinating seed which will start coming up in Autumn (generally speaking). Having stunted/stopped the plant´s growth, it can not spread/reproduce. Sustained treatment is required to control winter grass, and ok for Buffalo and Couch lawns.

FAQs

What is the best winter grass killer?

Propyzamide is a popular option for both pre and post emergent control of winter grass, particularly post emergent. The best way to treat winter grass is to apply a dedicated pre-emergent product prior to germination, Spartan is a good option for this and provides up to 6 months protection. Once the winter grass has appeared Spartan is not effective and Propyzamide would be recommended.

When should I spray for winter grass?

A pre-emergent such as Spartan should be applied prior to the winter grass germinating, this will vary depending on your location. As an example it is ideally applied in April for lawns in and around Perth Western Australia. Once the winter grass has appeared it is best to treat it with Propyzamide as soon as possible before it seeds and spreads.

What is propyzamide used for?

Propyzamide is used to treat a wide range of grassy and broadleaf weeds in various applications. It is most commonly used in lawns for the pre and post emergent treatment of winter grass (Poa Annua)

Our dog loves it but it wasn’t durable enough to last
Color: Dogwood Jack, Size: Large, Color: Dogwood Jack, Size: Large
Our lab took to it as soon as we gave it to her. Perfect size for our 80 lb yellow lab. However, now that it’s in about 10 days, she’s able to break off chunks from this bone that are dime size or larger, and we have to throw it away

No problems after a year and a half
Color: Dogwood & Calming, Size: Medium
Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long. I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

Great toy/feeder
My dog loves this!! It gives her entertainment and I use it for some of her breakfast. I put some in this and the rest in her usual food bowl. She goes to this first for the fun then goes and eats the rest of her breakfast from the usual bowl. Also good for slowing down eating while they have fun!

Good puzzle
My dog used to get puzzles often and loved them. We lost a lot of them in a house fire and subsequently move about a year ago and Im finally starting to replacing her old ones. She loves this thing. She definitely needs supervision because she’s already scratched it a bit from biting on it too hard but reasonably durable with that aside. (My dog is tough chew toys only kind of dog so fully expected) Easy to set up and fun for her is all I needed and it hit the mark

A fun puzzle for cats!
My 5 month kitten took to this puzzle right away as he watched me put food into each compartment. He solved it quickly and I think it will be a fun resource for his cognitive growth on a daily basis.
