Trizmax Herbicide Mix Ratio
When dealing with various types of corn such as field corn, field seed corn, field corn silage, sweet corn, and yellow corn, you should apply only 2.5 quarts of Trizmax herbicide per acre if the soil’s organic matter content is below 3%.
If it exceeds 3%, you have the flexibility to increase the amount to 3 quarts per acre.
For grain sorghum crops, the recommended application of Trizmax herbicide is 2.5 quarts per acre.
You can also use this product in two parts for Grain sorghum.
First, apply it at 1.25 to 1.5 quarts per acre before planting, 7 to 21 days in advance.
Then, apply a second time with 1.0 to 1.25 quarts per acre right before the Sorghum starts growing. Remember, the most you can use in this two-part method is 2.5 quarts per acre.
How to mix it?
Trizmax herbicide can be mixed according to the type of treatment you intend to use it for.
If you plan to use it as a pre-emergence application, you have to mix it differently than when treating it as a post-emergence treatment.
Mixing as pre-emergence treatment
As a pre-emergence treatment, you can mix Trizmax herbicide with clean water or liquid fertilizers.
You should not use suspension fertilizers, while the fluid fertilizers can be used only after making a compatibility test.
To perform a compatibility test, you have to go through the following steps:
- Add 1.0 pin of fertilizer or water to each of the two 1 quart jars.
- In one of the jars, include a quarter teaspoon or 1.2 milliliters of a compatible agent appropriate for this purpose, such as MixTM, Compex, or Unite (a quarter teaspoon corresponds to 2.0 pints per 100 gallons of spray). Gently shake or stir to combine the contents.
- For both jars, place the correct quantity of pesticide(s) in their respective proportions as directed by the specified label rates.
If you want to add multiple pesticides, then add them individually, starting with dry pesticides, followed by flowables, and finishing with emulsifiable concentrates.
Following each addition, gently shake or stir to ensure thorough blending. - Once all components are added, secure the lids tightly onto the jars and turn each jar upside down ten times to thoroughly combine the contents.
Allow the mixtures to sit for a duration of 15 to 30 minutes, and inspect for any indications of incompatibility such as separation, substantial flakes, precipitates, gels, a dense oily film on the jar’s surface, or other noticeable signs.
If you see signs of incompatibility, do not use the mixture.

How to use it?
When using Trizmax, you need to follow specific steps, just like you would for any other selective herbicide.
Below, you’ll find the steps explained in an easy-to-follow format on how to use the Trizmax herbicide:
- Check the weather and ensure that the forecast does not indicate strong winds exceeding 10 mph, rain, or storms.
Also, avoid applying it during extreme weather conditions such as excessively hot or cold temperatures. - Equip yourself with the appropriate personal protective equipment for handling herbicides.
To apply Trizmax, you’ll need: coveralls worn over a short-sleeved shirt and shorts, category A chemical-resistant gloves (barrier laminate, butyl rubber, neoprene rubber, or natural rubber), chemical-resistant footwear along with socks, chemical-resistant apron (only during mixing), and chemical-resistant headgear. - Once you are properly prepared, you can proceed to ready the container for mixing the herbicide.
During the mixing process, follow the specific amount indicated on the herbicide label.
If you intend to mix it with other herbicides, carefully read all labels for compatibility. - Mix all the ingredients and continuously stir and agitate until they are fully dissolved.
- Thoroughly spray the area, ensuring that the weeds are entirely covered with this herbicide.
Please remember that this can be used only as a pre-emergence treatment for corn, and you should not use it as a post-emergence treatment for this type of crop. - Once you’ve finished, clean your equipment. You need to flush the tank, hoses, boom, and nozzles with clean water.
If you’ve used a tank, wash its interior with a pressure washer.
You can also use a cleaning solution consisting of 1 gallon of household ammonia per 25 gallons of water to clean the tank. However, exercise caution, as the hoses, spray lines, and nozzles should remain in the cleaning solution for at least 1 minute.
Afterward, rinse everything again with clean water.
Trizmax and Rotational Crops
When using Trizmax herbicide while practicing crop rotation, it’s important to consider the following guidelines:
- Field corn, field seed corn, field silage corn, sweet corn, yellow popcorn, and grain sorghum (Concep® treated seed) can be replanted immediately in case of crop loss. Keep in mind that the reapplication of this product is not recommended.
- You can plant barley, rye, or winter wheat within 4.5 months after application.
- If you apply this herbicide after June 1, it is not recommended to rotate crops other than corn of all types and grain sorghum the next spring as this may result in crop injury.
- You can plant dry beans 10 months after you treat the area with Trizmax herbicide.
- Avoid rotating crops apart from Corn (all types), Cotton, Peanuts, Small grain cereals, Sorghum, or Soybeans during the Spring following the application of this product.
- In the regions of the High Plains and Intermountain areas in the Western region, characterized by limited and unpredictable rainfall or where irrigation is necessary, use this product exclusively when transitioning from Field corn or untreated Corn (all types) to Corn (all types) or Sorghum, or when Sorghum precedes other rotational crops.
- For all other types of crops, you must wait 18 months after application.
Trizmax herbicide restrictions
Trizmax has a set of restrictions that must be followed to ensure the proper application of this herbicide.
– If you are blending atrazine or atrazine-containing products with this herbicide for corn, ensure that the application rate of atrazine does not exceed 2.0 lbs per acre in a single application.
Also, the total lbs of atrazine applied should not exceed 2.5 lbs of active ingredient per acre per year.
– In cases where Corn hasn’t been treated with atrazine prior to emergence, you can apply a maximum of 2.0 lbs per acre through a broadcast application.
If a post-emergence treatment becomes necessary after an earlier herbicide application, the total atrazine applied shouldn’t exceed 2.5 lbs per acre per calendar year.
– For soils that are not highly erodible or are classified as highly erodible by the Natural Resource Conservation Service, apply a maximum of 2.0 lbs per acre in a single pre-emergence application if at least 30% of the soil has plant residues covering it.
– For soils classified as highly erodible by the Natural Resource Conservation Service, the limit is 1.6 lbs per acre for pre-emergence application if the surface has less than 30% plant residue coverage.
Alternatively, if applied only post-emergence, the limit is 2.0 lbs per acre.
– Regarding the grazing restrictions of Trizmax herbicide, the label states that animals must not graze or forage in the treated areas for a duration of 45 days following application.
– The pre-harvest interval (PHI) restriction is 60 days after application for field corn and 45 days after application for sweet corn.
– Application of this herbicide to areas with surface water is prohibited due to its toxicity to aquatic invertebrates.
– This herbicide must not be used in any type of irrigation system.
– The application of the herbicide must not exceed 3 quarts per acre per growing season.
– Trizmax herbicide cannot be used in conjunction with other solo HPPD inhibitor post-emergence herbicides like isoxaflutole (Balance Flexx), mesotrione (Callisto), tembotrione (Laudis), and topramezone (Impact) on areas that have been treated with Trizmax in the same season.
– Do not use a tank mix of this product and any organophosphate or carbamate insecticide for post-emergence applications on emerged Corn, as it has the potential to cause severe harm to the Corn plants.
– Restrict the application of this product to Field corn (grain, seed, or silage), Sweet corn (for pre-emergence applications only), Yellow popcorn (for pre-emergence applications only), and Grain sorghum (for pre-emergence applications only).
