Apply once daytime temperatures are consistently in the 40s and then can be applied throughout the year to prevent weeds from germinating and to control weeds up to 2 inches in height.

Description:

Semera SC is a herbicide that is primarily designed to prevent a wide variety of weeds in landscape beds and along cracks and crevices.  Although Semera SC is primarily designed to be a weed preventer it can also be used to kill weeds up to 2 inches in height.

Semera SC is significantly less toxic than comparable products with a Field EIQ Score of 7.9.

Rates:

Add 1/4 Ounce of Semera SC per gallons of water in your spray tank.  For best results we recommend filing half the water you plan to mix, then adding Semera SC and then finish adding the remaining water.

Semera SC should receive a 1/4 inch of water within 5 days of application to allow the product to penetrate into the soil.  If a 1/4 inch of rain does not occur within 5 days of application then hand watering is recommended.

For best results, use a Branch Creek Pump Free System with a Spray Wand Drift Guard.

Coverage:

At the low rate one bottle of Semera SC will cover up to 44,000 square feet and at the high rate will cover up to 29,000 square feet.  That's a lot of landscape beds.  In fact, one bottle of Semera SC will last most residential properties at least two years.

When Not To Use:

Do not apply during very windy conditions.  (Consult label for additional precautions and restrictions)

Hard to install as instructed.
Size: 32 oz
Nearly impossible to get it in the tire through the valve. Yes I removed the valve core. Broke the bead on the tire and dumped it in. That worked great! So far no leaks. They should definitely redesign the installation method.

Been using it for 15 years! Not sure where the Neg reviews come from?
Size: 16 oz
I've been using Liquitube since around 2010. I use it religiously in my ATVs and lawn tractor tires. Since I've been using this stuff, I've never had a flat before. I've pulled out nails and slivers of steel out of my ATV tires but yet none of them lose air or go flat. I think some of the negative reviews come from improper use of the product or not enough of the product is being used in the tires. I think this come from variance in formula charts that Liquitube has had in the past on their bottles and on their website. The chart on their website wouldn't match the formula that was provided on the bottle. So I think alot of people get mixed up and not knowing the correct amount to add to each tire. Now Liquitube just puts pictures on the side of the bottle with an ounce measurement below each picture to tell people how to use it. But even that can be confusing. For instance, take the picture of the ATV that they show. Below the ATV it says 32oz. Now some people probably think the 32oz is for the entire ATV. Well that isn't the case. They want you to use 32oz Per Tire! Years ago Liquitube even used to say on the bottle to use 32oz per tire on an ATV. Now they just show a picture with an amount below it. Now you'll come to find out that the 32oz they recommend doesn't match up to the formula they tell you to use to calculate how much each tire is supposed to get. So if you use the formula provided, you come to find that it calculates out to use less product per tire than what the bottle tells you to use. So that's very confusing as well. So if you use it long enough, you'll be able to know how much each tire will need from experience. Just make sure there's enough on the inside of the tire to coat the entire inside as well as leaving a bit left over to circulate in the tire so it can be ready for a large puncture if that ever happens. All in all, it's a good product that does what it claims. It lasts for as long as the tire does and it doesn't freeze up in the cold either! 5 stars!

Worked on slow leak… one month already!!!
Style: 18oz
Edit: Still holding proper pressure at 2-months !!! Had a slow leak where my tire went from 44psi to ~18psi over 2-3 days… Dashboard light would let me know every few days that I had a tire problem and I would inflate the tire back up to 44psi… Anyway, I used this product and filled air back to 44 psi and it’s held the pressure for a month already !!!! Be sure to deflate tire to ~15 PSI before adding the product… it only took about 30 seconds to empty the container into my tire with the tire pressure low. Very happy with this product !!!
