Frequently Asked Questions
How do I mix Ortho Killex 1L concentrate per gallon for 8,000 sq ft coverage?+
Mixing instructions depend on your sprayer type. The label gives precise dilution rates based on your equipment's output and target coverage. Follow those exactly — over or under-application hurts results. Calibrate your sprayer before mixing a large batch.
Can Ortho Killex be tank-mixed with liquid fertilizer in same pass?+
Not recommended unless the label says it's okay. Mixing different chemical formulations can cause compatibility problems, reduce efficacy, or damage the lawn. Apply herbicides and fertilizers separately with appropriate time between applications.
What spray volume per 1,000 sq ft gives uniform 8,000 sq ft coverage?+
Coverage depends on sprayer calibration and your application rate. The label gives the concentrate amount per area. Test with water first to make sure distribution is even. Adjust nozzle type, pressure, and walking speed to get consistent coverage across the 8,000 sq ft.
How long can diluted Ortho Killex sit in spray tank before losing potency?+
Use diluted solution within 24 hours for best results. The active ingredients degrade when mixed with water, especially in sunlight or extreme temperatures. Only mix what you'll use that day. Discard leftover solution per local regulations and rinse equipment thoroughly.
Does unopened Ortho Killex 1L concentrate have a 3-year shelf life?+
Yes, the shelf life is 36 months when stored in the original unopened container. Keep it from freezing and store in a cool, dry, well-ventilated area. Keep the cap tight to prevent leakage or chemical degradation.
What hose-end spr rate delivers 8,000 sq ft from one 1L Killex bottle?+
Hose-end sprayers vary in dilution and application rates. Check the Ortho Killex label for hose-end instructions. Set your sprayer to the recommended rate to get the right concentration and even distribution across the 8,000 sq ft.
What triple-rinse protocol cleans spray equipment after Ortho Killex use?+
Drain the tank completely, then rinse the inside with clean water and spray it through the nozzle. Repeat two more times, making sure all internal surfaces, hoses, and nozzles get flushed. Use a commercial tank cleaner for herbicide residue if needed. Dispose of rinse water per municipal guidelines.
Does Ortho Killex contain 2,4-D or other herbicides restricted on school properties?+
Yes, it contains 2,4-D, Mecoprop-p, and Dicamba. These are common broadleaf herbicides, but their use on public lands like school properties is regulated by provincial and municipal rules across Canada. Check your local bylaws and school board policies before applying on or near school grounds.
What are the physical dimensions and weight of the Ortho Killex 1L concentrate container?+
The product description doesn't list exact dimensions or weight. It comes in a standard recyclable HDPE plastic container with a 1-litre size and typical weight for that volume. It's compact enough for service vehicles or supply closets and doesn't need heavy-duty shelving.
For commercial landscaping operations, what is the typical longevity of a single 1L bottle of Ortho Killex concentrate?+
One 1L bottle covers up to 8,000 sq ft of turf. How long it lasts depends on the total area you manage. If you're handling multiple 5,000 sq ft residential properties, one bottle can cover more than one site. For larger commercial green spaces, it might handle a significant section. It's cost-effective for targeted broadleaf control across different property sizes.
