Ronstar 50 WSP Herbicide

Ronstar 50 WSP is a pre-emergent herbicide for control of annual grasses and broadleaf weeds in turf and on a variety of woody ornamental shrubs and trees. Ronstar herbicide controls weeds through shoots, not roots. So unlike competitive products that don't distinguish between roots of weeds and roots and desirable plants, Ronstar doesn't harm healthy turf. This product can be applied to sensitive grasses and areas where roots are already weakened by winterkill, pests or injury.
Product Highlights
  • Works on warm-season grasses.
  • One pre-emergent application - even in cold weather, or weeks before seed germination – controls weeds all season long.
  • Offers an environment conducive to sprigging.
  • Doesn’t inhibit turf root growth or recovery from damage.
  • Doesn’t prevent roots from tacking down.
Pests Controlled
  • Broadleaf weeds: Bittergrass, bristly oxtongue, carpetweed, cheeseweed, common groundsel, common purslane, evening primrose ragwort, lambsquarters, liverwort, oxalis, Pennsylvania smartweed, prostrate spurge, redroot pigweed, sow thistle, speedwell, spotted catsear, swinecress, yellow woodsorrel.
  • Grassy weeds: Annual bluegrass, barnyardgrass, crabgrass, fall panicum, goose grass, green foxtail, wild oats.

Rate of use: Apply Ronstar 50 WSP herbicide broadcast, in a minimum of 50 gallons of water per acre (1.14 gallons of water per 1,000 sqft), to established ornamentals at 4-8 WS packets per acre as a single over-the-top spray application or as a single directed spray application to the soil. The maximum amount allowed per year is 12 lbs of product/A (equivalent to 6 lbs ai/A/yr) except in areas of heavy weed infestation where the maximum amount allowed per year is 16 lbs of product/A (equivalent to 8 lbs ai/A/yr). The maximum number of applications that may be made per year is two. The maximum single application rate is 4 lbs ai/A. A subsequent application can be made 4 months after the previous treatment.

Very good quality comparable to OEM at a much more reasonable price point.
Size: (Pack of 1)
Last December we bought our first new car in 21 years and the first thing I did is stock up on cabin and engine air filters. I've got nothing against dealership OEM parts and pieces but what I do have an issue with is the prices. Luckily, we all have a bit of control over access to OEM quality parts and pieces at significantly more reasonable prices via Amazon. This filter and it's matching cabin filter are excellent in value and take less than 5 minutes to replace. Compare that to paying the hourly rate at your dealer plus the dealership retail price and you'll do what I did and stock up on these two filters. Definitely recommended.

Perfect fit for my 2018 Civic—easy, affordable, and worth it
Size: 9.5" x 10.9" x 2.1"
I’ve bought this cabin air filter multiple times for my 2018 Honda Civic, and it’s consistently great quality. It fits perfectly and is super easy to install—takes just a few minutes to swap out, and I always do it myself. Way cheaper than going to a shop or dealership. The airflow is smooth, there’s no smell at all, and it keeps the inside of my car feeling clean and fresh. No weird odors, no dust blowing in—just a solid, dependable filter that does its job well. This is the only one I’ll keep buying.

Do it mayne
Size: 9.5" x 10.9" x 2.1"
Good quality and fit but find it funny that the instructions with the air flow are on the side. I assume that would be facing out and was annoyed when I tried to close and it didn’t fit. Probably should have read the directions. Still would recommend
