LESCO LockUp Weed & Feed (Herbicide Guide)
LESCO LockUp Weed & Feed is a turf herbicide and fertilizer product, but its exact ingredients, rate, coverage, and directions depend on the package in hand. Check the full label and EPA Registration Number before use. Apply only to listed turf and weeds, calibrate your spreader to that label, and prevent granules from reaching gardens, drains, or water.
The must-have step is confirming which LockUp product you have before filling a spreader. Product names can cover different formulations or package sizes, and a setting or rate from another bag may not fit yours. One careful label check can prevent a poor result, turf injury, or damage to plants beyond the lawn.
Identify the exact product and read its label
The label is the controlling guide for what the product contains, where it can be used, and how to apply it. Start with the package, not a retailer description or a spreader chart for a similar product. Confirm the product identity before measuring an area or setting equipment.
Find these details on the bag:
- Exact product name and formulation
- Bag size and stated coverage
- EPA Registration Number
- Pesticide ingredient statement and fertilizer guaranteed analysis
- Label rate, listed turf types, target weeds, and use restrictions
The guaranteed analysis gives the fertilizer nutrient amounts. The pesticide ingredient statement identifies the herbicide ingredients. Do not infer either from “LockUp” alone, and do not assume that a particular herbicide blend or fertilizer grade applies to every package.
Read the full label, including directions and precautions. Check whether your lawn species and the weeds you want to control are listed. Look for limits on season, temperature, newly seeded or stressed turf, and repeat applications. If your package is missing its label or you cannot confirm its directions, do not apply until you obtain the correct label information.
Equipment Setup, Label Review & Site Safety
Preparation means checking the site, product, and equipment before opening the hopper. These steps help keep the treatment on eligible turf and reduce the chance that granules reach people, pets, ornamental plants, or water. Follow the package label for personal protective equipment and all site restrictions.
Walk the area first. Identify turf species, gardens, ornamental beds, trees, slopes, drains, water features, sidewalks, and places where people or pets may enter. Broadleaf herbicide residues can harm desirable plants, so note routes where granules could be tracked or washed off the lawn.
Use a clean, dry, working spreader suited to the product. Check that its gate opens and closes as intended, and confirm the spreader type and application pattern match the label directions. Wear the protective gear required by the label. Keep children and pets away as directed, and do not apply where drift, runoff, or tracking could carry product off target.
Calculate coverage and calibrate the spreader
Calibration is a measured test that helps you apply the label rate across a known area. It is not a way to guess a setting. Use the rate and spreader instructions for the exact product, then test the spreader on a measured area before treating the full lawn.
First measure the turf you plan to treat. Exclude beds, paths, and other areas not listed for use. Compare the measured area with the label’s stated rate and bag coverage; do not treat the entire property as lawn if it is not all eligible turf.
Use this checklist to keep the calculation tied to your package:
| Check | What to use |
|---|---|
| Product identity | Exact name, formulation, and EPA Registration Number on the bag |
| Application rate | Label rate for the intended turf and use |
| Treatment area | Measured area of eligible turf |
| Product amount | Amount calculated from that label rate and area |
| Spreader setting | Product- and spreader-specific label guidance, if provided |
| Coverage check | Label coverage matched to your measured area |
If the label gives no reliable setting for your spreader model, do not copy a setting from a different LESCO product or a generic chart. Follow label calibration directions and the spreader maker’s instructions for a measured test. Close the hopper when turning or stopping so granules do not build up in one place. Record your setting only as a note for this product and spreader combination, not as a universal value.
Field Application: Calibration, Coverage & Drift/Runoff Control
Application means spreading the product evenly over eligible turf at the label rate and under label-permitted conditions. A steady pace and planned route help limit missed strips and overlaps. Weather, turf condition, watering, and mowing instructions must come from the current package label.
Check the label for conditions that could prevent application, including restrictions tied to weather, turf stress, or recent seeding. Do not apply before heavy rain or where slopes, drains, or hard surfaces could carry granules off target. Avoid conditions that could move product onto sensitive plants or into water.
Plan a route before starting. Follow the label’s pattern instructions and keep a steady walking pace. Close the hopper while turning, stopping, or refilling. Keep granules off sidewalks, driveways, and other non-target surfaces. If stray product lands there, sweep it back onto labeled turf when safe and allowed by the label.
Do not use an application rate as a reason to treat an unlabeled grass type or weed. More product does not mean better control; exceeding the label rate can increase risk to turf and nearby plants. After spreading, follow the package for irrigation, rainfall, mowing, and access. Do not substitute timing advice from another weed-and-feed product.
Practical field scenarios: decisions before spreading
These scenarios show how to use the label and site check in common lawn situations. They are examples, not reports of named properties or proof of a product result. In each case, the package label decides whether treatment is allowed and what directions apply.
A mixed lawn with ornamental beds: A homeowner measures only the turf area and finds flower beds along the spreader route. The operator checks that the grass is listed, then plans a route that avoids throwing granules into the beds. If the label or site conditions do not allow safe application, that area is left untreated.
A sloped lawn above a drain: The operator sees that runoff could carry material toward a drain after rain. Rather than relying on a generic weather rule, they check the product label and avoid applying when the site could carry granules off target. The next step is to wait for label-permitted conditions, not to increase the rate.
A recently seeded patch: The owner wants to treat weeds in a new lawn, but the label’s restrictions for newly seeded turf have not been checked. The application pauses while the owner confirms whether that turf and timing are permitted. If they are not, the product is not applied there.
In each case, the useful decision happens before the hopper opens: confirm eligibility, map risk areas, and apply only when the label and site allow it.
Spreader Cleaning, Spill Response & Application Records
Closeout means dealing with leftover product and equipment without letting residue reach a drain, garden, or waterway. Follow the package for spills, disposal, cleaning, and empty containers. A brief record also helps you avoid repeating an application too soon or relying on an uncertain setting later.
After use, handle spills and empty packaging as the label directs. Do not wash residue into storm drains, gutters, ditches, or waterways. Clean equipment in a way that contains the residue and follows the label; do not rinse it where wash water can run off target. Wash your hands and launder contaminated clothing as directed.
Keep a simple application record with the date, product name, EPA Registration Number, treated area, amount used, spreader model and setting, weather notes, and any label-required follow-up. Record the label instructions you followed for watering, mowing, and access. These notes help you make a sound decision next time without treating a remembered setting as a substitute for the label.
Storage, Leftover Product & Seasonal Label Review
Storage means keeping the product in its original package and following the label’s storage and disposal directions. Leftovers should not be poured onto the lawn unless the label calls for that amount and the turf remains eligible. Recheck the label each season because your product, lawn conditions, or package directions may differ.
Close and store the bag as directed, away from children, pets, food, and water. Keep the label with the product. Do not transfer it to an unmarked container. If you have an unknown amount remaining, do not spread it simply to empty the bag; calculate the eligible area and follow the label rate.
Before seasonal use, check that the package is the same formulation you used before and that the label still matches your turf and intended weeds. Reconfirm any seasonal, seeding, mowing, irrigation, and repeat-application limits. If the package or directions have changed, start with the current label rather than last year’s notes.
Frequently asked questions
These answers give a short decision path, but the exact package label remains the authority. Check it for rates, species, timing, watering, mowing, access, and disposal. If a question depends on a product detail not shown here, verify the formulation and EPA Registration Number on your bag first.
