Pramitol 25E is a known leecher but how far it will depends on the amount of rain the area receives in a year. We would recommend not applying but you will need to stay at least 10 feet away, if not more depending on the slope of your property and how much rain is expected.
When using Pramitol 25E Herbicide, you actually want it to rain. This product will not provide herbicidal action in the treated area unless application is immediately followed by watering the area with at least ¼" of water or application of the product just prior to a rain event sufficient to penetrate to the root system of the target vegetation.
Yes, rainfall or watering in the Pramitol 25E after the application is recommended to help push the product deeper in the soil, which will increase the effectiveness towards the root system. If you have any other questions about Pramitol 25E, we recommend going over the product label
You should not use Pramitol 25E anywhere where you want plants to grow for at least one year. This is considered a soil sterilant and it lasts up to a year in the soil. If you are wanting to renovate an area, then you can use something that does not persist in the soil, such as GlyPhoSel Pro. We recommend waiting 2 weeks for the target plants to die completely before removing the dead plant material and putting down your groundcover or other desirable plants.
Pramitol 25E is not labeled to control horseweed/marestail.
You would want either to water in the Pramitol 25E right away or use a higher volume of water to spray it so that it gets into the soil. Waiting several months to water the product into the ground will greatly reduce the residual activity of this product. You should use 50-100 gallons of water per Acre, or at least 1-3 gallons of water per 1000 sq ft. Additional rainfall or irrigation will improve results. Please refer to the product label for complete application instructions.
Pramitol 25E is mixed at the rate of 8 ounces per gallon of water at the lowest dilution, up to 32 ounces per gallon for harder to kill brush. Please see the product label for complete application instructions.
You could potentially use a hose-end sprayer to apply Pramitol 25E if you can correctly calibrate your sprayer and avoid any potential contact or runoff to any desirable plants. For susceptible perennial grasses, you would use 12 - 18 oz per 1,000 square feet in sufficient water. For hard-to-kill perennial weeds and grasses, you would use 22 - 29.4 oz. per 1,000 sq ft. It is most important to use the correct amount of herbicide for the area you are treating and then using sufficient water or rainfall to irrigate it into the soil than it is to use a specific amount per gallon of water. Please refer to the product label for complete application instructions. Another option would be a backpack sprayer.
You will want to look at our Total Vegetation Management Page. The 3 most common bare ground herbicides to use that will prevent regrowth for the longest amount of time are Pramitol (up to 1 year), TVC Total Vegetation Control (season long control) and Bonide Ground Force Vegetation Management (up to 1 year).
You only want to mix up what you plan to use at a time and not keep it stored in a tank sprayer for more than 24-48 hours max if you want it to carry the same potency. Products like Pramitol 25E, if used correctly should only have to be reapplied every year so if you are finding you are having to treat more frequently in areas you used it in, we would suggest using a little higher ratio per 1000 sq/ft and use a higher water volume over that whole area to ensure it is getting deep enough in the soil to set up an adequate long lasting barrier.
Pramitol 25E can be applied anytime target weeds are actively growing or just before seed germination when the ground is not frozen, and temperatures are not at or below freezing. Pramitol can prevent growth for up to 1 year.
Pramitol 25E does not contain glyphosate. You can add a glyphosate product for better kill of existing plants.
Pramitol 25E is not specifically labeled for bamboo elimination. Any glyphosate product may or may not do the job right off to control the Bamboo. Since bamboo roots go so deep, you would need to apply either a product like Rodeo/Roundup QuikPro at the highest rates directly to the fresh cut stump of the bamboo after you cut it down level to the ground, or use a brush and stump killer undiluted directly on the fresh stump.
We would advise to allow 1-2 hours to let the Pramitol dry sufficiently before releasing any animals back into the treated area. Keep in mind that Pramitol shoud not be used in any grazing areas.
Pramitol 25E is a total vegetation killer and will eliminate anything growing where you spray it. This will keep anything new from growing in the treated areas for at least 1 year. Caution should be used during application as some leaching in the soil could occur and destroy nearby desirable vegetation and turf. Pramitol is mixed at the rate of 8 ounces per each gallon of water at the lowest dilution, up to 32 ounces per gallon for harder to kill brush. The time it takes for plant death to occur will depend on how much product is absorbed through the root system, whether or not rainfall or irrigation occurs after application, and plant stress. It can take days to weeks before complete death is visible. Children should be kept out of the treated area during application but can safely return as soon as everything is fully dry. Please see the product label for complete application directions.
I do apologize but we do not carry any product or device to determine if your subcontractor applied the product or not. We recommend that you contact the manufacturer for details regarding this at 281-832-2500.
