Tank-mixing glyphosate with 2,4-D is a common practice to achieve excellent control of both grasses and dicots. However, 2,4-D antagonism of glyphosate was reported in some species, such as Johnson grass,8) wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), and wild oats (Avena fatua L.).
The introduction of this herbicide tolerance package created a lot of questions; hopefully this article will help answer some of those questions for you and guide you to a successful weedmanagement program in 2019. Can I use glufosinate and glyphosate in a tank mix? Short answer: Absolutely!
Glyphosate and glufosinate are both non-selective herbicides that target grass and species. Glufosinate is more effective on annual broadleaf weeds, while glyphosate is more effective on annual grasses. Glufosinate is also effective on many troublesome glyphosate-resistant weeds.
A classic example of an antagonistic interaction that occurs in peanut country is when graminicides [grass herbicides such as Select (clethodim) or Poast (sethoxydim) or Fusilade (fluazifop-P)] are tank-mixed with broadleaf herbicides such as Basagran (bentazon), Cadre (imazapic) or 2,4-DB.
"In the field, we found that applying the herbicides through separate tanks, lines, and booms where the chemicals only mixed on the plants eliminated herbicide antagonism," Ferguson said.
There is no specific antidote for 2,4-D herbicide poisoning. Early initiation of urinary alkalinization (UA) can decrease the systemic toxicity and can also hamper the progression of rhabdomyolysis and acute renal failure.
Conventional cotton is highly sensitive to 2,4-D (Dunlap 1948), especially at seedling growth stages (McIlrath and Ergle 1953). Because of the hormone-like characteristics, even trace amounts of 2,4-D drift can cause crop injury, delayed maturity, and yield loss.
The results showed that 2,4-D antagonizes glyphosate remarkably in glyphosate-resistant populations but only marginally in susceptible populations. This antagonism is related to reduced glyphosate uptake and (to a lesser extent) translocation.

Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.

Investigation of Antagonism with Glyphosate and Glufosinate Tank Mixtures refers to the process of assessing how these two herbicides interact when mixed together in a solution, specifically examining whether one herbicide reduces the effectiveness of the other.
Pesticide applicators, agricultural researchers, and companies involved in the production or use of these chemicals may be required to file investigations, particularly if they are studying the efficacy and safety of these mixtures in specific applications.
To fill out the investigation, one needs to provide details such as the concentrations of each herbicide used, the conditions of the application (e.g., environmental conditions, timing), observations of effectiveness, and any adverse effects noted during the mixing and application process.
The purpose is to determine whether combining Glyphosate and Glufosinate in tank mixtures can produce antagonistic effects that impact weed control efficacy, as well as to ensure safe application practices.
Required information may include the types and rates of herbicides used, environmental conditions at the time of application, the timing of applications, observed weed control outcomes, and any phytotoxicity or other negative effects on crops.
