Mojave 70 EG Herbicide Rates (Mixing Guide)
Mojave 70 EG is a 70% hexazinone water-dispersible granule, but its correct rate depends on the labeled site, target vegetation, and application method. Use the current container label to choose the rate and mixing directions. Measure the treatment area, calculate only the amount needed, and do not borrow rates or mixing steps from another product.
A brush-free patch can look like a quick win, right up until a drifted spray damages the plants you meant to keep. Herbicide work rewards careful planning more than guesswork. I treat the rate calculation as a property map problem first: confirm the site, mark what must stay safe, and only then work out the product amount.
There is no responsible one-size-fits-all number for this product. The instructions on the current Mojave 70 EG label control. If your site, target vegetation, or application method is not listed there, do not assume the product is suitable.
Product, Site Eligibility & Safety Preparation
Mojave 70 EG is a 70% hexazinone water-dispersible granule. A water-dispersible granule mixes into a carrier as directed by its label; it is not a license to use any carrier or spray method. Before measuring product, confirm that the current label permits your site, target, and planned application.
Confirm the label and site
The product name alone cannot tell you the right rate. Rates and uses can differ by target plant, site, and application method, so read the full current label for the product in your container. Confirm the label is current and check for state or local restrictions before you plan the job.
Look for these items:
- The permitted site and target vegetation
- The labeled application method and rate units
- Application timing and weather limits
- The permitted carrier and any mixing directions
- Required personal protective equipment (PPE)
- Restrictions for people, animals, desirable plants, water, and other sensitive areas
- Re-entry, cleanup, storage, and disposal directions
Do not use a rate from another hexazinone product, even if the active ingredient seems familiar. Formulation and label directions matter. If the current label does not list your intended site or target, stop and ask your local pesticide regulator or a qualified pesticide professional for guidance.
Check the property before treatment
Walk the area before you mix. Mark the treatment boundary and identify desirable plants, wells, surface water, drains, and other locations the label says to protect. Consider where water flows after rain, not just where the ground looks level on a dry day.
Off-target movement or runoff can harm plants and sensitive areas. Do not apply if wind, expected rain, drainage, or site conditions could carry product outside the permitted area. Follow the label’s limits; if conditions are uncertain, postpone the work.
Keep people, pets, and unprotected workers away as the label directs. Put on the required PPE before handling the product, and keep it on through mixing and cleanup for as long as the label requires. The label, not a general rule of thumb, sets the exact PPE and re-entry instructions.
Rate Calculation, Mixing & Field Application
The application rate is the amount of product the label permits for a defined area or method. First measure the area and match it to the label’s units. Then calculate the product amount from that labeled rate; do not guess a tank concentration from the product name or percentage.
Measure the treatment area
For a uniform area, measure its length and width and calculate the area using units that match the label. For an irregular boundary, divide it into simple shapes, measure each one, and add the areas. Leave out untreated buffers, desirable vegetation, and any restricted areas.
One acre contains 43,560 square feet. Use that conversion only if it helps match your measured area to the rate units on the label. Record your measurements so another person can check the calculation before mixing.
Calculate the product amount from the label
Use the rate and units printed for your specific site, target, and application method. If the label rate is given per unit of area, multiply that rate by the area you will actually treat. Do not exceed the labeled rate.
| Planning item | Calculation or check |
|---|---|
| Treatment area | Measure the area to be treated, excluding protected areas |
| Labeled rate | Copy the rate and units for the exact site and method from the current label |
| Product needed | Labeled rate × treatment area in matching units |
| Tank area | Determine the area one tank will treat from calibration, not by guesswork |
| Product per tank | Labeled rate × the area that tank will treat |
For example, if a label gives a rate per acre, the calculation uses the number of acres you will treat. This is a calculation method, not a suggested Mojave 70 EG rate. If your label uses different units or a different application method, follow that label method instead.
Plan the tank volume separately
The amount of carrier in a tank is not the same as the amount of product required per area. First determine how much area a tank will cover with your equipment. Then calculate the labeled product amount for that area. Do not turn an area rate into a tank concentration without knowing the tank’s coverage.
If the label does not make the calculation clear, do not improvise. Ask a qualified pesticide professional or the product registrant for help interpreting the current label. Measure product with a scale or a calibrated measure suited to the label’s units. A scoop volume is not a reliable substitute for a stated weight, and handfuls are not a measure.
Mix and apply only as directed
Wear the label-required PPE and mix only what you need for the planned treatment. Use only the label-authorized carrier, mixing order, and agitation. These directions are specific to the product; do not copy them from another herbicide.
Apply evenly at the labeled rate using only the permitted equipment and method. Keep the treatment within the marked boundary. Avoid overlap, leaks, and off-target movement. Stop if wind, rain, runoff, or changing site conditions could move product into protected areas.
A practical pre-mix check is to compare three numbers: the area measured, the area the tank will treat, and the product amount calculated from the label. If they do not agree, pause and recalculate before opening the container.
Applicator Calibration, Cleanup & Equipment Care
Calibration checks how much carrier your equipment applies over a known area. It helps you plan tank coverage, but it does not set the herbicide rate. Use calibration to match the label rate to your equipment, then apply only with equipment and methods permitted by the label.
Check and calibrate the applicator
Inspect the applicator before use. Check for leaks, worn parts, and any condition that could cause uneven application or drift. Keep spray or granules inside the labeled treatment area, and do not use equipment that cannot apply the product as directed.
Use the label’s instructions and your equipment manual to check application output over a measured area. Calculate how much area the planned tank volume will cover. Then use the label rate to calculate the product for that coverage. Do not change the labeled area rate to compensate for poor calibration.
If the equipment is not applying evenly, fix the issue before treatment. Recheck coverage after an adjustment. Keep people and animals clear as the label requires, and protect nearby desirable plants, wells, surface water, and restricted areas.
Finish safely and keep records
After application, follow the label directions for rinsate, equipment cleaning, and container disposal. Keep wash water and spills out of drains and away from water or non-target plants. Do not dispose of leftovers or rinsate in a place the label or local rules prohibit.
Record the product name, label rate and units used, treated area, date, application method, and any other details required by the label or local rules. A simple record helps you verify what was applied if you return to the site or need to answer a question later.
If a spill or off-target movement occurs, stop work and follow the label’s spill instructions. Do not rinse or spread the material into a drain or waterway. Use the label and local emergency guidance to decide what steps are required.
Storage, Disposal & Seasonal Restrictions
Storage and disposal directions are part of safe use, not an afterthought. Keep the product in its original container and follow the label for storage conditions, container handling, and disposal. Also check the label’s timing and weather restrictions before each application, since conditions can change between planning and treatment.
Store and dispose of product properly
Keep the container closed, labeled, and stored as directed. Store it where children and animals cannot reach it, and do not transfer it to a food or drink container. Follow the label for handling unused product and empty containers, along with any applicable local disposal rules.
Do not assume a municipal collection site will accept pesticide or rinsate. Check with the local waste authority if the label or local rules do not make the disposal route clear. Never put product or contaminated wash water where it could reach a drain, surface water, or sensitive vegetation.
Check timing and conditions again
Before application, reread the label’s seasonal timing, weather limits, and other restrictions for your intended site and target. Do not infer that a condition is acceptable because it was acceptable on another property or for another herbicide.
If rain, wind, drainage, or site conditions could move product beyond the treatment area, postpone the application. The same applies if the target or site cannot be clearly matched to a labeled use. Waiting is safer than trying to correct an off-target application later.
Frequently Asked Questions
These answers explain the main rate and mixing decisions, but they do not replace the current product label. For any site-specific question, use the directions for the exact use and method listed on your container, and confirm state or local rules before applying.
What is the correct Mojave 70 EG rate?
There is no single rate that can be given from the product name alone. Use the current label rate for your site, target vegetation, and application method.
Can I use a rate from another hexazinone product?
No. Do not transfer a rate or mixing direction from another product. Follow the current Mojave 70 EG label.
How do I calculate how much product to mix?
Measure the area, match its units to the label, and multiply by the labeled rate. If planning by tank, first determine the area that tank will treat.
Can I estimate product with a scoop or handful?
Do not estimate by handfuls or assume a scoop equals a stated weight. Use a scale or calibrated measure suited to the label’s units.
How do I know how much area one tank will cover?
Check and calibrate the applicator over a measured area using its instructions and the label. Tank coverage depends on the equipment and application setup.
Can I use any carrier or spray equipment?
No. Use only the carrier, equipment, and application method permitted by the current label.
What PPE should I wear?
Use the PPE listed on the current label. Do not substitute another product’s PPE directions or rely on a general recommendation.
What if my site or target is not listed?
Do not apply on that basis. Ask a qualified pesticide professional or the relevant local pesticide regulator for guidance.
What should I do if wind or rain could move product off target?
Stop or postpone application. Follow the label’s restrictions and spill directions if product has already moved outside the intended area.
How should I handle leftover mix and rinsate?
Follow the label’s instructions for rinsate, cleanup, and disposal. Keep it away from drains, water, and non-target vegetation.
