Prizefighter® is part of a new class of natural weed killers that penetrates the cell wall of a weed, shutting down the flow of nutrients and disrupting cellular processes; thus breaking down weeds from the inside out - a much more through killing mechanism than slats or acids. Visible results are achieved within 15 minutes; green plant tissue is killed on contact due to the rapid desiccation of weed's foliage. Prizefighter’s versatility makes it a useful addition to your landscaping maintenance plan. 

Prizefighter can also be used as an insecticide to control Prizefighter™ is used for control of Adelgids, Aphids, Earwigs, Grasshoppers, Thrips, Lacebugs, Mites, Plantbugs, Psyllids, Sawfly Larvae, Scales, Tent Caterpillars, Whiteflies and Wooly Aphids (Not Approved for Use in California).  

Why is Prizefighter a Leading Organic Weed Killer?

Herbicidal soaps work by penetrating the waxy cuticle of plants, causing the plant to dehydrate and die. The active ingredients accumulate in plants and cause intracellular damage, leading to cell death. Activity is non-selective and will kill plants the soap comes into contact with, but will not translocate to underground portions of the plant or harm the bark of mature, woody plants.  Can be safely sprayed around the base of trees, shrubs, hops, grapes without worry.  

Use on weeds within vegetable and flower gardens, landscaped areas, lawns (for spot treatment only), in the vicinity of small fruits and fruit trees, around and on buildings, sidewalks, fences, bark mulch, driveways, patios and gravel.  Use on moss and algae, around and on buildings, roofs, decks, sidewalks, fences, bark mulch, driveways, patios and gravel. Prizefighter can even be used in cool weather. Areas can be planted five days after treatment.

Prizefighter reduces tree toxicity risks and leaves no harmful residue in the soil. It won’t stain bricks, concrete or asphalt and people and pets can re-enter areas once spray dries.

            Good quality and cannot beat the value you get with a suit
            Size: Medium, Color: Black
            I recently purchased the WEEN CHARM Men's Suits Slim Fit for my son's homecoming and I must say, I am impressed with the quality and fit of this suit. Firstly, the material used in this suit is of exceptional quality. The fabric feels soft and smooth, and it has a nice weight to it which gives it a luxurious feel. The suit doesn't feel cheap or flimsy at all. The slim fit design is impeccable. It hugs my son's body in all the right places, giving him a sharp and stylish look. The suit is tailored to perfection and accentuates his physique beautifully. I also appreciate the attention to detail in the craftsmanship. The stitching is neat and sturdy, and there were no loose threads or flaws that I could find. The suit looks like it was made with care and precision. Additionally, the suit was surprisingly comfortable. My son didn't complain about any discomfort or restriction of movement throughout the evening, which is always a plus. The only reason I haven't given it a five-star rating is because the suit did require some minor alterations for a perfect fit. Nonetheless, this is a small inconvenience considering the overall satisfaction we had with this purchase. In conclusion, I highly recommend the WEEN CHARM Men's Suits Slim Fit. It is a stylish, well-made suit that will definitely make a statement at any formal event. My son looked dashing in it and received many compliments.

            Fit like a glove and soft to the touch.
            Size: Small, Color: Black
            My son loved the suit. It was not itchy. The fabric was soft. He did not like the vest but it is because he normally wears baggy clothes. He did not want a slim fit suit but he ended feeling good in it. For the price you can't miss. He is 140 lbs and is 5'7". We used the sizing chart for reference and bought size small. The length and waist of the pants were perfect and the arms were just right.

            I felt cute
            Gorgeous. Little snug for the jacket for recommended size but I got 6 months to lose some stomach to fit better LOL I don't blame the jacket.

            Color is not accurate
            Size: Medium, Color: Grey
            Suit quality is good. This is NOT dark grey. Its a very standard grey when you have it in person. I might return just for this reason as we were really looking for a dark grey suit.
