Mixing Instructions
Proper mixing is crucial for effective weed control with Hi-Yield Triclopyr Ester. Always add the herbicide to water in a spray tank and mix thoroughly. Refer to the label for specific rates.
Recommended Mixing Ratio
The recommended mixing ratio for Hi-Yield Triclopyr Ester is typically 3/8 to 3/4 fluid ounces per 1,000 square feet; This translates to roughly 2.25 to 4.5 teaspoons per gallon of water for spot treatments. It’s crucial to mix this product with sufficient water to ensure uniform coverage of the target area. For more precise applications, always refer to the product label, as variations in concentration or application needs might require slight adjustments. Remember that proper mixing ensures effectiveness against broadleaf weeds and Bermudagrass suppression. When mixing with other herbicides, always follow all label instructions and precautions for each product used. Improper mixing can lead to poor results.
Water Volume Considerations
When using Hi-Yield Triclopyr Ester, the volume of water is critical for effective application. The goal is to use enough water to ensure uniform coverage of the target area without causing runoff. Generally, sufficient water should be used to thoroughly wet the foliage of weeds without oversaturating the soil. This ensures that the herbicide is absorbed by the leaves effectively. For spot treatments, a gallon of water might suffice, while larger areas will require more. The exact amount will depend on your sprayer and the density of weeds. Always aim for a fine spray and avoid excessive use, as this can lead to wasted product and less effective results.
Mixing Sequence
The recommended mixing sequence for Hi-Yield Triclopyr Ester is crucial for proper dispersion and effectiveness. Start by adding about half of the required clean water to your spray tank. Next, add the measured amount of Hi-Yield Triclopyr Ester to the tank. Be sure to add the product to the water. Once the herbicide is in, complete filling the tank with the remaining water while continuing agitation. This ensures the herbicide mixes thoroughly. Continue moderate agitation while spraying. Do not add any additional products without verifying compatibility. Always follow the product label for specific mixing instructions and precautions to ensure the best results.
Application Methods and Precautions
For application, use a hand pump or backpack sprayer for accuracy. Apply to actively growing weeds. Do not water for 24 hours after application. Always consult the product label for complete instructions.
Best Application Practices
When applying Hi-Yield Triclopyr Ester, it is crucial to use a hand pump or backpack sprayer to ensure accurate and even coverage. Avoid using hose-end sprayers, as they may not provide the desired precision. Apply the herbicide when weeds are actively growing and not stressed due to extreme conditions; Ensure thorough wetting of the target weeds but avoid excessive runoff. Do not water the treated area for at least 24 hours post-application to allow the herbicide to be absorbed effectively. Consistent application and adherence to recommended rates are essential for optimal weed control. Always consult the product label for detailed guidance.
Sprayer Type Recommendations
For applying Hi-Yield Triclopyr Ester, using a hand pump or backpack sprayer is highly recommended over hose-end sprayers. These sprayers allow for more accurate and controlled application, ensuring the herbicide reaches the target weeds effectively while minimizing overspray. Hand pump sprayers are ideal for smaller areas, while backpack sprayers are better suited for larger lawns and landscapes. Low-pressure application is advisable, typically around 20-40 psi, to prevent drift and ensure thorough wetting of the weeds without excessive runoff. Using the correct sprayer type is critical for achieving the best results with triclopyr ester herbicides.
Post-Application Waiting Period
After applying Hi-Yield Triclopyr Ester, it is crucial to avoid watering the treated area for at least 24 hours to allow the herbicide to absorb into the weeds effectively. Furthermore, a waiting period of at least three weeks is required before overseeding or reseeding the treated area. This waiting period ensures the herbicide has fully dissipated and does not interfere with the germination and establishment of new grass seeds. Slit seeding or overseeding, where seeds are planted into the soil, should be delayed for the same period to avoid any negative impact on seed viability. Adhering to these waiting periods is essential for successful weed control and subsequent lawn establishment.
Additional Considerations
Hi-Yield Triclopyr Ester can be tank mixed with other herbicides, like 2,4-D. Always follow label directions of each product. Reseeding should be delayed for at least three weeks post-application to prevent any complications.

Typically, a mix ratio of 1 to 3 quarts of Triclopyr Ester combined with the labeled rates of the other product per 100 gallons of spray mixture is used. Always follow specific label directions and precautions. Prior to using, perform a small-scale test to ensure compatibility. Careful mixing will provide the desired result.
Reseeding Precautions
After applying Hi-Yield Triclopyr Ester, it is vital to observe specific waiting periods before reseeding or overseeding your lawn. Typically, a minimum of three weeks should pass after application before introducing new seed. This waiting period allows the herbicide to dissipate and prevents damage to germinating seedlings. Slit seeding or overseeding, which involves using machinery to plant seed, requires the same waiting period. The herbicide can negatively affect the germination of new grass if done too soon. Ensure proper timing when planning to reseed areas treated with triclopyr ester. This will result in successful establishment of new turfgrass.
