- Tankmix Compatibility
- 8.2 Sprayer Compatibility
Always predetermine the compatibility of this product or labeled mixtures of this product with water carrier or sprayable fluid fertilizer carrier by mixing small proportional quantities in advance. See the "STANDARD SPRAYABLE FLUID FERTILIZER COMPATIBILITY TEST" section in this label to determine the compatibility of this product and the labeled tank mixtures specified for use with sprayable fluid fertilizer carrier.
For recommended tank mixes, see tank mix sections 11.3 and 12.3 of this label. It is the pesticide user's responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. Do not tank mix this product with any fungicide, insecticide, adjuvant or fertilizer solution not recommended on this label without first testing compatibility. Use this product only in sprayers that have good agitation and are in good running condition. Make sure the sprayer has been cleaned by following the instructions on the previously used products label before mixing and applying this product.
Mix this product or labeled tank mixture of this product with the appropriate carrier as follows:
1. Place a 20- to 35-mesh screen or wetting basket over filling port.
2. Through the screen, fill the sprayer tank one-half full with appropriate carrier. For preemergence applications liquid fertilizer (except suspension fertilizers) may be used as the carrier. For postemergence applications, use clean water only as the carrier.
3. If a compatibility agent is necessary to improve mixing or to prevent the formation of undesirable and unsprayable gels or precipitates, while agitating add it to the carrier already in the tank. For example, AMS should be added at this step and agitate until completely dispersed. Use only compatibility agents cleared by the FDA for this use. Read and follow all directions for use, cautionary statements and all other information appearing on the selected compatibility agent label. Check for adequate agitation.
4. If a wettable powder or dry flowable formulation is used, make a slurry with water, and add it slowly through the screen into the tank. Continue agitation.
5. If a flowable formulation is used, add slowly through screen into the tank. Mixing and compatibility may be improved when the flowable is premixed one part flowable with one part water and added slowly to the tank in diluted form.
6. Add this product slowly through the screen into the tank. Longer agitation may be required for complete dispersion of this product when using cold water sources. Mixing and compatibility may be improved when this product is prediluted with two parts of water and added to the tank in diluted form.
7. Add appropriate adjuvant and UAN if needed and allowed, then complete filling the sprayer tank with carrier. If a labeled tank mixture product is to be used, add the required amount near the end of the filling process. Remove hose from tank immediately after filling to avoid siphoning back into the water source.
Maintain good agitation at all times until the contents of the tank are sprayed.
NOTE: If spray mixture is allowed to settle at any time, thorough agitation is required to resuspend the mixture before spraying is resumed. Keep bypass line on or near bottom of tank to minimize foaming. Screen size in nozzle or line strainers should be no finer than 50-mesh. Carefully select the proper nozzle to avoid spraying a fine mist. Check for even distribution of spray droplets. For best results with ground application, use flat-fan or whirl chamber nozzle. To reduce loss of chemical due to drift of a fine mist, apply at pressures less than 40 psi.
11.3 Tank Mixtures
Harness MAX Herbicide may be tank-mixed with the following products for improved weed control spectrum in burndown or preemergence applications in corn. These tank mixtures may also be used to include a different site of action herbicide to help control or manage the development of resistant weed biotypes. Ensure that the specific product being used in the tank mixture is registered for the specific preplant, at-planting, or preemergence application timing to corn. It is the pesticide user's responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. Not all tank mixtures with HarnessMAX Herbicide have been tested at all labeled use rates in all environments. It is suggested that the user choose a use rate of the tank mix product in the middle of the rate range to reduce the potential for injury to corn. Use rates for this product can be found in the table in Section 11.1 of this label. When using fluid fertilizer as a carrier, refer to the label of the specific tank mixture product for mixing directions. The most restrictive label directions apply. For mixing instructions, see the "MIXING, SPRAYING AND HANDLING" section of this label.
Burndown Tank Mixtures
Harness MAX Herbicide may be applied in tank mixture with other registered herbicides for burndown of emerged weeds and residual weed control. Application can be made prior to planting corn or before corn emergence. This product may be tank mixed with Roundup (R) brand glyphosate-only agricultural herbicides, Gramoxone (R) brands, dicamba brands and/or 2,4-D. Use the adjuvant system which is recommended for use with the burndown herbicide. It is the pesticide user's responsibility to ensure that all products in the listed mixtures are registered for application [burndown] to corn. Users must follow the most restrictive directions and precautionary language of the products in the mixture (for example, first aid from one product, spray drift management from another).
Preemergence Tank Mixtures
Harness MAX Herbicide may be applied in tank mixture with other registered herbicides for preemergence residual weed control. It is the pesticide user's responsibility to ensure that all products in the listed mixtures are registered for application [preemergence] to corn.

12.3 Tank Mixtures
This product may be tank-mixed with the following products for postemergence use in corn (after corn has emerged). Ensure that the specific product being used in the tank mixture is registered for application postemergence (in-crop) to corn. It is the pesticide user's responsibility to ensure that all products in the listed mixtures are registered for application [postemergence] to corn. Users must follow the most restrictive directions and precautionary language of the products in the mixture (for example, first aid from one product, spray drift management from another). Not all tank mixtures with HarnessMAX Herbicide have been tested at all labeled use rates in all environments. It is suggested that the user choose a use rate of the tank mix product in the middle of the rate range to reduce the potential for injury to corn.
Observe directions for use, precautions and restrictions on the label of the postemergence herbicide. If unsatisfactory weed control occurs (due to excessively dry or excessively wet conditions) following the earlier application, a postemergence application of an appropriate labeled grass and/or broadleaf weed herbicide may be used. If a postemergence treatment includes the herbicide used early preplant, do not exceed the maximum labeled rate for corn on a given soil texture.
Use rates for this product can be found in the table in Section 12.1 of this label. Do not apply less than 40 fl oz per acre of this product postemergence or loss of residual control may result.
