0-0-7 Prodiamine Granular Pre-Emergent Herbicide

Yard Mastery 0-0-7 Prodiamine is a granular pre-emergent designed to stop weeds in the lawn, such as crabgrass, poa annua, bittercress, chickweed, and henbit. It’s the same active ingredient the pros use, formulated for easy DIY application.

Most DIYers use this Prodiamine in the spring to stop crabgrass. Crabgrass is an annual grassy weed that germinates in spring, grows lime green and large during summer, and then, towards late fall, drops seeds. The following spring, the process starts all over again. This is why crabgrass is called an “annual” grass weed.

The good news is that crabgrass can be stopped effectively using this product. The best time to apply Prodiamine is in the spring or fall, as soil temperatures are between 55°F to 70°F. This will give you approximately 3 months of pre-emergence protection.

Fast and easy but I dont trust the process to be fully automated.
The process was very smooth and fairly quick. The only challenge I had was that the CLAIM status showed complete but I had to manually go look up the status. There was no email or notification it was closed. After manually checking the status, I called customer support and they said since I called in, they would process the payout. I wonder if I didnt call in if they would have processed it? Also, the phone rep said they would issue me a amazon egift card but then the next day I received a email saying they mailed out the payout. Very poor communication but so far the process was easy and fast.

Excellent Warranty Coverage – Fast, Fair, and Hassle-Free
I purchased the ASURION 3-Year Portable Electronic Accident Protection Plan ($500–$599.99) for an Android 13 8.8” touchscreen stereo installed in my BMW (CCC system). After about two years of normal use, the Android stereo stopped working completely. I filed a claim through Asurion’s website, and the process was straightforward. Initially, Asurion asked me to remove the unit and prepare it for return, advising that they would email me a prepaid shipping label. I de-installed the stereo from my car and packed it up as instructed. After two days passed without receiving the shipping label, I was about to follow up—when I received an email notifying me that Asurion had issued a full refund of $459.00. I did not have to ship the unit back. That level of service exceeded my expectations. The claim was handled quickly, communication was clear, and the resolution was fair and hassle-free. I purchase an Asurion protection plan with every high-dollar item I buy on Amazon. I’ve had to file a three claims over the years, and each time the experience has reinforced that this coverage is well worth the cost. When something fails outside the manufacturer’s warranty, it’s a relief knowing Asurion stands behind the product. Highly recommended for expensive electronics.

PROTECTION WITH ABSOLUTE EMPATHY & RESPECT
Had an issue with a product I purchased over a year ago along with an Asurion protection plan. Thank God I chose this extended plan. I was waiting for a return ticket you get it repaired and Asurion sent me a full refund. I am so grateful for Asurion and I encourage everyone to get these plans and get the added protection on products NOT made as they once were. We as buyers are terribly taken advantage of with the garbage sent to us that we pay very very high costs of. Asurion has NEVER failed me and the customer service reps are extraordinary and kind and very very respectful. Thank you to you all at Asurion, Johnny A. Cheers...
